  FIG. 1 is a hardware block diagram showing the configuration of a personal computer and a scanner.

  As shown in the figure, a personal computer has a central processing unit (CPU) as a center, a main memory (MM), a hard disk device (HD) connected by a bus (BUS), and a display device (DISP) as output means. And a keyboard (KBD) as input means.

  A scanner (SCN) as a photographing unit is connected via a USB interface (USB I / F).

  Although the illustration of the internal configuration of this scanner (SCN) is omitted, it incorporates an infrared irradiation means (LED), a filter that cuts the predetermined wavelength component of the reflected light, and an image sensor (CCD or CMOS) that captures the image. The reflected light from an ID tag, a paper keyboard or a paper controller, which will be described later, can be imaged, and a dot pattern printed on the medium surface can be processed as image data.

<Description of dot pattern GRID1>
Next, a dot pattern used in the present invention will be described with reference to FIGS.

  FIG. 2 is an explanatory diagram showing GRID1, which is an example of the dot pattern of the present invention.

  In these drawings, vertical and horizontal grid lines are provided for convenience of explanation, and are not present on the actual print surface. The key dots 2, information dots 3, reference grid point dots 4 and the like constituting the dot pattern 1 are printed with carbon ink that absorbs infrared light when the scanner as imaging means has infrared irradiation means. It is desirable that

  FIG. 3 is an enlarged view showing an example of a dot pattern information dot and a bit display of data defined therein. FIGS. 4A and 4B are explanatory diagrams showing information dots arranged around key dots.

  The information input / output method using a dot pattern according to the present invention includes generation of a dot pattern 1, recognition of the dot pattern 1, and means for outputting information and a program from the dot pattern 1. That is, the dot pattern 1 is captured as image data by the camera, the reference grid point dot 4 is extracted first, and then the key dot 2 is extracted because the dot is not originally placed at the position where the reference grid point dot 4 is located. Next, the information dot 3 is extracted and digitized to extract an information area to digitize the information, and information and a program are output from the dot pattern 1 based on the numerical information. For example, information such as voice or a program is output from the dot pattern 1 to an information output device, a personal computer, a PDA, a mobile phone, or the like.

  The dot pattern 1 according to the present invention is generated in accordance with a predetermined rule for fine dots, that is, key dots 2, information dots 3, and reference grid point dots 4, in order to recognize information such as voice by a dot code generation algorithm. Arrange. As shown in FIG. 2, the block of the dot pattern 1 representing information has a 5 × 5 reference grid point dot 4 on the basis of the key dot 2, and the center of the center surrounded by the four reference grid point dots 4. Information dots 3 are arranged around the virtual grid point 5. Arbitrary numerical information is defined in this block. In the illustrated example of FIG. 2, a state is shown in which four blocks (inside the thick line frame) of the dot pattern 1 are arranged in parallel. Of course, the dot pattern 1 is not limited to four blocks.

  One corresponding information and program can be output to one block, or one corresponding information and program can be output to a plurality of blocks.

When the dot pattern 1 is captured as image data by the camera, the reference grid point dot 4 corrects distortion of the lens of the camera, imaging from an oblique direction, expansion / contraction of the paper surface, curvature of the medium surface, and distortion during printing. Can do. Specifically, a correction function (X _n , Y _n ) = f (X _n ′, Y _n ′) for converting the distorted four reference grid point dots 4 into the original square is obtained, and the same function is obtained. Then, the information dot 3 is corrected to obtain a correct information dot 3 vector.

  If the reference grid dot 4 is arranged in the dot pattern 1, the image data obtained by capturing the dot pattern 1 with the camera corrects the distortion caused by the camera. Even when the image data of the dot pattern 1 is captured by the camera, it can be accurately recognized. Even if the camera is tilted and read with respect to the surface of the dot pattern 1, the dot pattern 1 can be accurately recognized.

  As shown in FIG. 2, the key dot 2 is a dot in which four reference grid point dots 4 at the corners of the four corners of the block are shifted in a certain direction. The key dot 2 is a representative point of the dot pattern 1 for one block representing the information dot 3. For example, the reference grid point dots 4 at the corners of the four corners of the block of the dot pattern 1 are shifted upward by 0.1 mm. When the information dot 3 represents the X and Y coordinate values, the coordinate point is a position where the key dot 2 is shifted downward by 0.1 mm. However, this numerical value is not limited to this, and can be changed according to the size of the block of the dot pattern 1.

  The information dot 3 is a dot for recognizing various information. The information dot 3 is arranged around the key dot 2 as a representative point, and the center surrounded by the four reference grid point dots 4 is set as a virtual grid point 5 and expressed as a vector using this as a starting point. It is arranged at the end point. For example, the information dot 3 is surrounded by the reference grid point dot 4, and as shown in FIG. 3A, a dot 0.1 mm away from the virtual grid point 5 has a direction and length expressed by a vector. Therefore, it is rotated 45 degrees clockwise and arranged in 8 directions to represent 3 bits. Accordingly, 3 bits × 16 pieces = 48 bits can be expressed by one block of dot pattern 1.

FIG. 3B is a method of defining information dots 3 having 2 bits for each grid in the dot pattern of FIG. 2, and each 2-bit information is shifted by shifting the dots in the + direction and the x direction. Defined. Thus, although 48-bit information can be originally defined, data can be given every 32 bits by dividing according to usage. A maximum of 2 ¹⁶ (about 65000) dot pattern formats can be realized by combining the + direction and the X direction.

  In the illustrated example, 3 bits are expressed by arranging in 8 directions. However, the present invention is not limited to this, and 4 bits can be expressed by arranging in 16 directions. Of course, various changes can be made. is there.

  The diameter of the key dot 2, the information dot 3 or the reference grid point dot 4 is preferably about 0.05 mm in consideration of appearance, printing accuracy with respect to paper quality, camera resolution, and optimal digitization.

  Further, in consideration of a necessary amount of information with respect to the imaging area and misidentification of the various dots 2, 3, and 4, it is desirable that the interval between the reference grid point dots 4 is about 0.5 mm vertically and horizontally. In consideration of misrecognition of the reference grid point dot 4 and the information dot 3, the shift of the key dot 2 is preferably about 20% of the grid interval.

  The distance between the information dot 3 and the virtual grid point 5 surrounded by the four reference grid point dots 4 is preferably about 15 to 30% of the distance between the adjacent virtual grid points 5. This is because if the distance between the information dot 3 and the virtual lattice point 5 is closer than this distance, the dots are easily recognized as a large lump and become unsightly as the dot pattern 1. On the contrary, if the distance between the information dot 3 and the virtual grid point 5 is longer than this distance, it is difficult to identify which of the adjacent virtual grid points 5 is the information dot 3 having the vector directivity. Because it becomes.

For example, as shown in FIG. 4A, in the information dot 3, the lattice interval in which I ₁ to I ₁₆ are arranged clockwise from the block center is 0.5 mm, and 2 bits × 2 mm and 3 bits × 16 = 48. Represents a bit.

In addition, it is possible to further provide sub-blocks having independent information contents in the block and not affected by other information contents. FIG. 4B illustrates this, and sub-blocks [I ₁ , I ₂ , I ₃ , I ₄ ], [I ₅ , I ₆ , I ₇ , I, which are composed of four information dots 3. ₈ ], [I ₉ , I ₁₀ , I ₁₁ , I ₁₂ ], [I ₁₃ , I ₁₄ , I ₁₅ , I ₁₆ ] are independent data (3 bits × 4 = 12 bits) developed into information dot 3 It has come to be. By providing sub-blocks in this way, error checking can be easily performed on a sub-block basis.

  It is desirable that the vector direction (rotation direction) of the information dots 3 is uniformly determined every 30 to 90 degrees.

  FIG. 5 shows an example of the information dot 3 and the bit display of the data defined therein, and shows another form.

  In addition, using two types of information dots 3 that are long and short from the virtual lattice point 5 surrounded by the reference lattice point dot 4 and eight vector directions, 4 bits can be expressed. At this time, it is desirable that the longer one is about 25 to 30% of the distance between adjacent virtual lattice points 5, and the shorter one is about 15 to 20%. However, it is desirable that the center interval between the long and short information dots 3 is longer than the diameter of these dots.

The information dot 3 surrounded by the four reference grid point dots 4 is preferably one dot in consideration of appearance. However, if it is desired to ignore the appearance and increase the amount of information, one bit is assigned to each vector, and the information dot 3 is expressed by a plurality of dots, so that a large amount of information can be provided. For example, the vector of concentric eight directions, an information dot 3 surrounded by four points lattice dots 4 can represent information of 2 ^8, and 16 pieces of information dots of one block 2 ^128.

  FIG. 6 is an example of information dot and bit display of data defined therein, where (a) shows two dots, (b) shows four dots, and (c) shows five dots arranged. It is shown.

  FIG. 7 shows a modification of the dot pattern, where (a) is a six information dot arrangement type, (b) is a nine information dot arrangement type, (c) is a 12 information dot arrangement type, and (d). Is a schematic diagram of a 36 information dot arrangement type.

  The dot pattern 1 shown in FIGS. 2 and 4 shows an example in which 16 (4 × 4) information dots 3 are arranged in one block. However, the information dots 3 are not limited to 16 pieces arranged in one block, and can be variously changed. For example, according to the amount of information required or the resolution of the camera, six information dots 3 (2 × 3) are arranged in one block (a), and nine information dots 3 in one block (3 × 3) Arranged (b), 12 (3 × 4) information dots 3 arranged in one block (c), or 36 (d) arranged 36 information dots 3 in one block.

  8 to 9 are explanatory diagrams showing the relationship among the dot pattern, the code value, and the identifier.

The dot pattern is a dot pattern composed of 4 × 4 block areas, and is partitioned into C _{1-0 to} C _31-30 within this block. FIG. 9 shows the dot code format of each area.

FIG. 9A shows a case where the dot pattern is composed of only code values, and the code value for each dot of the dot pattern in each region shown in FIG. 8 is registered in C _{0 to} C ₂₇ . Parities are registered in C _{28 to} C ₃₀ .

In FIG. 9B, XY coordinates are registered together with the code value. That is, in FIG. _8, X coordinates in the C 0 -C _7, Y coordinates for C 8 _{-C 15,} code values for C 16 _{-C 27} is adapted to be registered, respectively.

  As described above, in this embodiment, the XY coordinates can be registered together with the code value in the dot pattern.

  Further, FIG. 9C shows a format in which coordinate indexes are registered together with XY coordinates. The coordinate index is an area for registering a page number or the like of paper as a medium, and an identifier or page number for identifying the medium itself in which the XY coordinates are registered as a dot pattern can be registered.

  As described above, the dot pattern of the present invention can be formatted in a flexible manner, such as when registering only code values, when registering code values and XY coordinates, and when registering XY coordinates together with coordinate indexes. It is.

<Description of dot pattern GRID2>
Next, the basic principle of the GRID2 dot pattern will be described with reference to FIGS. GRID2 is a dot placement algorithm using a difference method.

  First, as shown in FIG. 10, lattice lines (y1 to y7, x1 to x5) are assumed at predetermined intervals in the XY direction. The intersection of the grid lines is called a grid point. In this embodiment, 4 blocks (4 grids) in the XY direction, that is, 4 × 4 = 16 blocks (16 grids), are defined as one information block as the minimum block (1 grid) surrounded by the four grid points. To do. It should be noted that the information block unit of 16 blocks is merely an example, and it is needless to say that an information block can be configured with an arbitrary number of blocks.

  The four corner points constituting the rectangular area of the information block are corner dots (x1y1, x1y5, x5y1, x5y5) (dots surrounded by a circle in the figure). These four corner dots are matched with the grid points.

  Thus, the information block can be recognized by finding four corner dots that coincide with the lattice points. However, even if only this corner dot can recognize the information block, the direction is not known. For example, if the direction of the information block cannot be recognized, even if it is the same information block, if it is rotated by ± 90 degrees or 180 degrees, it becomes completely different information.

  Therefore, vector dots (key dots) are arranged at the lattice points in the rectangular area of the information block or in the adjacent rectangular area. In the figure, a dot (x0y3) surrounded by a triangle is a key dot (vector dot) arranged at the first grid point vertically above the midpoint of the grid line constituting the upper side of the information block. Yes. Similarly, the lower information block key dot is arranged at the first grid point (x4y3) vertically above the midpoint of the grid line constituting the lower side in the information block.

In the present embodiment, the distance between lattices (inter-grid) is 0.25 mm. Therefore, one side of the information block is 0.25 mm × 4 grid = 1 mm. This area is 1 mm × 1 mm = 1 mm ² . In this range, 14-bit information can be stored. When 2 bits are used as control data, 12-bit information can be stored. Note that the distance between the lattices (inter-grid) is set to 0.25 mm only, and may be freely changed within a range of, for example, 0.25 to 0.5 mm.

  In GRID2, every other information dot is arranged at a position shifted from the lattice point in the x and y directions. The diameter of the information dot is preferably greater than 0.03 to 0.05 mm, and the amount of deviation from the lattice point is preferably about 15 to 25% of the distance between lattices. Since this deviation amount is also an example, it may not necessarily be within this range, but generally when the deviation amount is larger than 25%, the dot pattern tends to appear as a pattern when visually observed.

  In other words, since the deviation from the grid point is alternately vertical (y direction) deviation and left and right (x direction) deviation, there is no uneven distribution of dot arrangement, and moire and patterns on the paper surface. The appearance of the printed paper can be maintained.

  By adopting such an arrangement principle, every other information dot is necessarily arranged on a grid line in the y direction (see FIG. 11). This means that when reading a dot pattern, it is only necessary to find every other grid line arranged in a straight line in the y-direction or the x-direction, and the calculation algorithm in the information processing apparatus at the time of recognition is simplified. In addition, there is an advantage that speed can be increased.

  Also, even if the dot pattern is deformed due to the curvature of the paper surface, etc., the grid line may not be an exact straight line, but since it is a gentle curve approximating a straight line, finding the grid line is relatively easy. Therefore, it can be said that the algorithm is strong against deformation of the paper surface and displacement and distortion of the reading optical system.

  FIG. 12 explains the meaning of the information dots. In the figure, + indicates a grid point, and ● indicates a dot (information dot). The case where the information dot is arranged in the −y direction with respect to the grid point is 0, and the case where the information dot is arranged in the + y direction is 1.

  Next, a specific information dot arrangement state and a reading algorithm will be described with reference to FIG.

  In the figure, a circled number 1 information dot (hereinafter referred to as information dot (1)) is shifted in the + direction from the grid point (x2y1), meaning "1". In addition, the information dot (2) (the numerical value with circles in the figure) means “1” because it is shifted in the + y direction from the grid point (x3y1). Further, since the information dot (3) (circled number in the figure) is shifted in the −x direction from the lattice point (x4y1), the information dot (4) (circled number in the figure) is “0”. The information dot (5) (circled number in the figure) means “0”.

  In the case of the dot pattern shown in FIG. 13, the information dots (1) to (17) have the following values.

(1) = 1
(2) = 1
(3) = 0
(4) = 0
(5) = 0
(6) = 1
(7) = 0
(8) = 1
(9) = 0
(10) = 1
(11) = 1
(12) = 0
(13) = 0
(14) = 0
(15) = 0
(16) = 1
(17) = 1

  In the present embodiment, the value is calculated using the information acquisition algorithm based on the difference method, which will be described below, for the information bit. However, the information dot may be output as it is as the information bit. Further, a true value may be calculated by performing arithmetic processing on a value of a security table to be described later for this information bit.

  Next, an information acquisition method using the difference method based on the dot pattern of the present embodiment will be described with reference to FIG.

  In the description of the present embodiment, the numbers enclosed in parentheses are the numbers enclosed in a circle (circled numbers) in the figure, and the numbers enclosed in [] are the numbers enclosed in a square shape in the figure. is doing.

  In this embodiment, each 14-bit value in an information block is expressed by the difference between adjacent information dots. For example, the first bit is obtained by the difference between the information dot (1) and the information dot (5) at the position of +1 lattice in the x direction. That is, [1] = (5) − (1). Here, since the information dot (5) means "0" and the information dot (1) means "1", the first bit [1] means 0-1 or "1". Similarly, the second bit [2] is represented by [2] = (6)-(2) and the third bit [3] = (7)-(3).

  In the following difference equation, the value is an absolute value.

[1] = (5)-(1) = 0-1 = 1
[2] = (6)-(2) = 1-1 = 0
[3] = (7)-(3) = 0-0 = 0

  Next, the fourth bit [4] is obtained by the difference between the information dot (8) and the information dot (5) located immediately below the vector dot. Therefore, the fourth bit [4] to the sixth bit [6] take a difference from the value of the information dot at the position of one grid in the + x direction and one grid in the + y direction.

  In this way, the fourth bit [4] to the sixth bit [6] can be obtained by the following equation.

[4] = (8)-(5) = 1-0 = 1
[5] = (9)-(6) = 0-1 = 1
[6] = (10)-(7) = 1-0 = 1

  Next, with respect to the seventh bit [7] to the ninth bit [9], the difference between the values of the information bits located at one grid in the + x direction and one grid in the −y direction is obtained.

  In this way, the seventh bit [7] to the ninth bit [9] can be obtained by the following expression.

[7] = (12) − (8) = 0−1 = 1
[8] = (13)-(9) = 0-0 = 0
[9] = (14)-(10) = 0-1 = 1

  Next, for the tenth bit [10] to the twelfth bit [12], the difference between the information dots at the position of one grid in the + x direction is obtained as follows.

[10] = (15)-(12) = 0-0 = 0
[11] = (16)-(13) = 1-0 = 1
[12] = (17)-(14) = 1-0 = 1

  Finally, the 13th bit [13] and the 14th bit [14] take the difference between the information dot (8) and the information dot at the positions of +1 and −1 grids in the x direction, respectively, as follows: Ask for.

[13] = (8)-(4) = 1-0 = 1
[14] = (11) − (8) = 1−1 = 0

  The first bit [1] to the 14th bit [14] may be used as read data as they are as true values, but in order to ensure security, a security table corresponding to the 14 bits is provided, A key parameter corresponding to a bit may be defined, and a true value may be obtained by adding or multiplying the key parameter to the read data.

  In this case, the true value T can be obtained by Tn = [n] + Kn (n: 1 to 14, Tn: true value, [n]: read value, Kn: key parameter). A security table storing such key parameters can be registered in a ROM in the optical reader.

For example, if the following key parameters are set as a security table,
K ₁ = 0
K ₂ = 0
K ₃ = 1
K ₄ = 0
K ₅ = 1
K ₆ = 1
K ₇ = 0
K ₈ = 1
K ₉ = 1
K ₁₀ = 0
K ₁₁ = 0
K ₁₂ = 0
K ₁₃ = 1
K ₁₄ = 1

  The true values T1 to T14 can be obtained as follows.

T ₁ = [1] + K ₁ = 1 + 0 = 1
T ₂ = [2] + K ₂ = 0 + 0 = 0
T ₃ = [3] + K ₃ = 0 + 1 = 1
T ₄ = [4] + K ₄ = 1 + 0 = 1
_{T 5 = [5] + K} 5 = 1 + 1 = 0
T ₆ = [6] + K ₆ = 1 + 1 + 1 = 0
T ₇ = [7] + K ₇ = 1 + 0 = 1
T ₈ = [8] + K ₈ = 0 + 1 = 1
T ₉ = [9] + K ₉ = 1 + 1 + 1 = 0
T ₁₀ = [10] + K ₁₀ = 0 + 0 = 0
T ₁₁ = [11] + K ₁₁ = 1 + 0 = 1
T ₁₂ = [12] + K ₁₂ = 1 + 0 = 1
T ₁₃ = [13] + K ₁₃ = 1 + 1 + 1 = 0
T ₁₄ = [14] + K ₁₄ = 0 + 1 = 1

  FIG. 14 shows the correspondence between the information bits described above, the security table, and the true value.

  In the above description, the information bit is obtained from the information dot and the true value is obtained by referring to the security table. On the contrary, when the dot pattern is generated from the true value, the nth bit [N] can be obtained by [n] = Tn−Kn.

  Here, as an example, when T1 = 1, T2 = 0, and T3 = 1, the first bit [1] to the third bit [3] are obtained by the following equations.

[1] = 1-0 = 1
[2] = 0-0 = 0
[3] = 1-1 = 0

  The first bit [1] to the third bit [3] are represented by the following differential equation.

[1] = (5)-(1)
[2] = (6)-(2)
[3] = (7) − (3)

  Here, given initial values of (1) = 1, (2) = 1, and (3) = 0, dots (5) to (7) can be obtained as follows.

(5) = (1) + [1] = 1 + 1 = 0
(6) = (2) + [2] = 1 + 0 = 1
(7) = (3) + [3] = 0 + 0 = 0

  Although the following description is omitted, the values of the dots (8) to (14) can be obtained similarly, and the dots may be arranged based on these values.

  The initial values of the dots (1) to (3) are arbitrary random numbers (0 or 1).

  That is, by adding the values of information bits [1] to [3] to the assigned initial dots (1) to (3), dots (5) to (5) to (5) to (5) to ( The value of 7) can be obtained. Similarly, the values of dots (8) to (10) can be obtained by adding the values of information bits [4] to [6] to the values of dots (5) to (7). Furthermore, the values of dots (12) to (14) can be obtained by adding the values of information bits [7] to [9] to these. Furthermore, the values of dots (15) to (17) can be obtained by adding the values of information bits [10] to [12] to this.

  The dots (4) and (11) are obtained by subtracting the information bit [13] and adding the information bit [14] based on the dot (8) calculated above.

  As described above, in this embodiment, the arrangement of dots on the grid line yn is determined based on the dot arrangement on the grid line y (n−1), and the entire information dot arrangement is determined by sequentially repeating the dot arrangement. To do.

(Paper keyboard)
15 to 17 are diagrams illustrating a paper keyboard that is an embodiment of the present invention.

  FIG. 15 is an explanatory diagram showing a paper keyboard in which a scanner (SCN) reads a dot pattern printed on one side (medium side) of a paper keyboard as a medium, and performs various input operations of the personal computer. is there. This paper keyboard has a booklet shape with one long side bound, and a keyboard (key top) pattern is printed on each page surface of the booklet.

  Specifically, as shown in FIG. 16, a single hiragana or English character (“A”, “I”, “A”, “B”, etc.) or a plurality of characters imitating the key top of a personal computer. A plurality of square image areas printed with the following words (“send”, “yes”, etc.) are provided.

  In each rectangular image area, the code value of the interrupt key corresponding to each character (in the case of a single-character square image area) is registered as a dot pattern. It matches the code value defined at the key top of each character of the hardware keyboard.

  That is, when the scanner (SCN) reads the dot pattern of the square image area on which the English letter “A” is printed, the code value of the interrupt key generated when the “A” key of the hardware keyboard is pressed. Is input to a personal computer (information processing apparatus).

  In addition, as a function that does not exist on the hardware keyboard, words such as greetings "Nice to meet you", "Hisashiri", "Thank you", etc. are printed as square image areas, and these areas correspond to each wording The character string code value string is printed as a dot pattern. In addition to the case where the character string is printed as it is as a dot pattern of code values assigned to the key tops, an input command code value of a predetermined number of digits is printed as a dot pattern, which will be described later with reference to FIG. Character input information corresponding to the index table to be stored may be held in advance.

  In FIG. 16, a square image area in which words such as “view home page” and “send email” are printed in addition to these words, the former is a browser program, and the latter is a mailer program. The start command code value is printed as a dot pattern.

  In FIG. 16, the keyboard is arranged in the order of the Japanese syllabary and alphabetical order. However, the arrangement is not limited to this and may be the same as the actual JIS layout keyboard.

  In addition, on the paper keyboard shown in FIG. 16, in addition to the code values described above as dot patterns, the above coordinate values are also registered in each square image region.

  Here, when the dot pattern on the paper keyboard surface (medium surface) is imaged, in addition to replacing keyboard input using code values, it is also possible to replace mouse or tablet input using coordinate values. Is possible. As described above, whether to use a code value or a coordinate value is determined by providing a square image area on which a character “code / coordinate switching” is displayed on a paper keyboard and adopting the code value in this area. A code value for switching whether to adopt the coordinate value may be printed as a dot pattern, and the input of the code value and the coordinate value may be switched each time this square image area is scanned.

  Furthermore, the dot-patterned code value printed in the square image region can be used as a code value having a different meaning from the code value depending on the reading procedure.

  For example, when the dot pattern of the square image area “A” is read continuously within a predetermined time (the scanner is tapped on the square image area “A”), that is, the tip of the scanner is continuously applied to the medium surface. The coordinate image reading image has changed, such as when the up / down movement is repeated so that it touches or separates, or when the scanner is scratched, that is, when the scanner is rubbed back and forth or left and right on the key top image. In this case, the same state as when the shift key of the hardware keyboard is pressed may be used.

  Specifically, when a lowercase “a” is photographed by a scanner (SCN), the code value of the interrupt key corresponding to “A” is input to the personal computer, and then the tapping operation is performed, the personal computer The central processing unit (CPU) detects a change in the captured image of the scanner based on the program, and converts the interrupt code value corresponding to the lowercase “a” into the interrupt code value corresponding to the uppercase “A”. And hand it over to an application program such as a word processor.

  In the case of tapping operation, the dot pattern is read only once, and then only the intensity of light recognized by the scanner (SCN) CMOS sensor is detected to detect that the tapping operation is being performed. May be.

  In addition to such a tapping operation, uppercase “A” is used when the scanner is stopped on the square image area for a predetermined time or longer to read a dot pattern, and lowercase letters are used for a predetermined time or less. It may be determined as “a” and each code value may be transferred to the application program.

  Furthermore, when the coordinate value changes while reading the same code value on the square image area (scratch operation of the scanner), when the scanner tilt is detected by the change in the light intensity distribution within the captured image range, etc. It is also possible to switch between uppercase and lowercase input and pass each code value to the application program.

  FIG. 31B is a diagram for explaining this grid tapping operation.

  That is, the grid tapping operation of the scanner (SCN) is an operation in which the scanner is set up vertically on the map, and the scanner is moved up and down to hit the icon on the medium surface (here, the key top image of the letter “A”). It is.

  FIGS. 31A and 31C are explanatory views showing the grid scratch operation of the scanner (SCN).

  The grid scratch operation refers to an operation of moving the scanner a plurality of times so as to be scratched on the map. The user (operator) performs a grid scratch operation on the icon on the medium surface (here, the key top image of the letter “A”). As a result, the input characters to the application program can be switched between the uppercase “A” and lowercase “a” interrupt codes.

  FIG. 32 is an explanatory diagram showing the grid grinding operation of the scanner (SCN).

  The grid grind operation is an operation of rotating the rear end (upward in the drawing) of the scanner while capturing the same icon (here, the key top image of the letter “A” in English). Grid grinding to the right (clockwise) with respect to the paper surface may be referred to as “grid grinding right”, and grid grinding to the left (counterclockwise) may be referred to as “grid grinding left”.

  As shown in FIG. 78, when the brightness of the captured image of the scanner is recognized and the brightness area changes with respect to the center of the imaging, the central processing unit recognizes that the scanner has been operated as shown in FIG. it can. Keyboard operations such as keyboard shift, control, and conversion of input characters may be performed by such scanner operations.

  Another example of the operation of changing the brightness of the image captured by the scanner is a grid pump operation (not shown). The grid pump operation is an operation of repeatedly tilting the scanner forward or backward.

  FIG. 78 is a diagram illustrating the relationship between the scanner tilt and angle.

The dot pattern on the key top image is superimposed and printed in the same direction as the vertical direction of the paper. As shown in (a), an angle formed by the direction of the dot pattern and the direction of the camera in the scanner is α. Further, as shown in (b), when the user tilts the scanner, an angle formed between the tilt of the scanner and the direction of the camera is β. In this case, an angle γ formed by the direction of the dot pattern and the inclination of the scanner is an angle obtained by inclining the scanner with respect to the key top image. That is, the angle γ is
γ = α + β
It becomes.

  FIG. 79 to FIG. 83 are diagrams for explaining a method of calculating the brightness and the inclination direction of the image captured by the scanner in the above-described scanner operation.

  As shown in FIG. 78B, the inclination of the scanner (imaging means) with respect to the medium surface (key top image) in the vertical direction can be recognized by the difference in brightness in the imaging field of view of the scanner.

  The inclination direction of the scanner means an angle formed between the scanner and the map as shown in FIG. Which direction the user tilts the scanner can be obtained by the following method.

  First, calibration is performed. The scanner is set up vertically with respect to the map, and the brightness of the cells 1 to 48 shown in FIG. 79 is measured. FIG. 79 shows an area around the scanner. The brightness at this time is assumed to be BL0 (i). i is the value of the measured cell. For example, the brightness of the cell No. 24 is displayed as BL0 (24).

  Two LEDs are installed inside the scanner. Therefore, even if the scanner is set up vertically with respect to the map, the brightness differs between cells near the LED and cells located away from the LED. Therefore, calibration is performed.

Next, the brightness when the scanner is tilted is measured. As shown in FIG. 80A, when the scanner is tilted in a certain direction, the brightness from cell 1 to cell 48 is measured, and the brightness in cell i is defined as BL (i). Then, the difference between BL (i) and BL0 (i) in each cell is calculated. And
Max (BL0 (i) -BL (i))
Calculate

  When the scanner is tilted, the direction opposite to the tilted direction becomes dark. This is because the LED also tilts in the direction in which the scanner is tilted, so that the distance from the LED is longer in the direction opposite to the tilted direction. Therefore, as shown in FIG. 80B, the direction opposite to the cell where the difference is the maximum is the position where the scanner is tilted.

  As a result, the direction in which the scanner is tilted is determined.

  Next, another method for determining the inclination direction and the angle by performing calibration will be described with reference to FIGS.

  First calibrate. First, the scanner is set up vertically with respect to the map, the brightness of the cells 1 to 48 shown in FIG. 79 is measured, and the brightness in the cell i is set to BL0 (i).

  Next, the scanner is tilted by 45 °, and is rotated once around the pen tip as shown in FIG. In this case, the brightness when the scanner comes to the position of the cell i is BL45 (i). BL45 (i) from cell 1 to cell 48 is obtained. Calibration is completed by the above operation.

  Next, when the user tilts the scanner, the brightness from cell 1 to cell 48 is measured, and the brightness in cell i is set to BL (i), i = 1, n (= 48). And

を求める。

Ask for.

  Since BL0 (i) -BL45 (i) is constant, when the value of BL0 (i) -BL (i) is the largest, that is, when BL (i) is the smallest.

は最大値となる。上述した如く、スキャナを傾けた方向と逆の方向が最も暗くなるため、この場合のセルｉの逆方向が、スキャナを傾けた方向となる。

Is the maximum value. As described above, the direction opposite to the direction in which the scanner is tilted is the darkest, so the reverse direction of the cell i in this case is the direction in which the scanner is tilted.

  The angle at which the scanner is tilted is

となる。

It becomes.

  In addition, although the above-described equation assumes that the angle θ is linear with respect to brightness, strictly speaking, approximation can be further improved by approximating as follows using a trigonometric function or the like. This way the angle is

となる。

It becomes.

  FIG. 82 shows a method of measuring the tilt direction using a Fourier function.

  As shown in FIG. 81, eight cells 1 to 8 are used as measuring points, and the brightness of each cell is measured.

The sine function is
αj {sin (1/2) j−1 (θ−βj)}
It is represented by That is, there are two unknowns.

  Accordingly, when there are n measurement points, there are n discrete points, so the sum of n / 2 sine functions is obtained, and this is the brightness BL (i) at the radius from the analysis center. That is,

ただし、n=2m（nは測点の数）
で表される。

However, n = 2m (n is the number of stations)
It is represented by

  In this embodiment, since the number of measurement points is 8, n = 8. Therefore, the Fourier series α1 to α4 and β1 to β4 are obtained by synthesizing four sine function equations. Then, the brightness BL (i) at the radius from the analysis center is represented by the sum of four sine functions.

  From the above formula, the angle θ at which BL (i) becomes the minimum value is the darkest position, and the opposite direction of 180 ° is the direction in which the scanner is inclined.

  FIG. 83 shows a method of measuring the tilt direction by solving an nth-order equation.

The graph in FIG. 83 shows an n-order function. When an n-order function is used, the brightness BL (i) at the radius from the analysis center is
BL (i) = α1 (θ−β1) · α2 (θ−β2)... Αj (θ−βj)
However, j = n / 2, n = 2m
It is represented by

  As shown in FIG. 81, since there are eight measurement points in this embodiment, it is necessary to obtain eight solutions. Since one equation includes two unknowns αj and βj, four equations are solved to obtain α1 to α4 and β1 to β4.

  Thereby, the angle θ at which BL (i) is the minimum value is obtained. The position corresponding to the angle θ is the darkest position, and the opposite direction by 180 degrees is the direction in which the scanner is inclined.

  Note that the measurement method shown in FIGS. 82 and 83 cannot measure the inclination of the scanner with respect to the vertical line of the key top image. Therefore, by using in combination with the measurement method shown in FIGS. 79 to 80, it is possible to measure a specifically tilted angle.

  Further, as described above with reference to FIG. 78, when the dot pattern on the medium surface is read using the scanner, the fact that the scanner is tilted with respect to the medium surface is recognized by the difference in brightness of the captured image of the scanner. By doing so, it is possible to operate the GUI on the screen in accordance with the inclination direction of the scanner with respect to the medium surface.

  As shown in FIG. 78, when the central processing unit (CPU) recognizes the brightness of the captured image of the scanner and the brightness area moves to the opposite side with respect to the imaging center, the scanner is tilted with respect to the medium surface. Can be determined.

  On the other hand, when the brightness of the captured image changes so as to rotate with respect to the imaging center, the central processing unit (CPU) determines that the scanner has performed a grid grinding operation (see FIG. 32).

  In addition, when the brightness of the captured image changes repeatedly in the forward or backward direction with respect to the imaging center, the central processing unit confirms that the scanner has been repeatedly tilted forward or backward (grid pump operation). Can be judged. Along with such operation operation of the scanner, GUI operations such as movement of the cursor displayed on the display screen and scrolling of the screen may be performed.

  GUI operations on the screen are specifically operations such as scrolling the screen, moving the cursor, designating icons on the screen, dragging and dropping operations, menu selection, and mouse operation operations such as character position input operation. is there.

(Paper controller)
18 to 30 are diagrams illustrating a paper controller which is an embodiment of the present invention.

  On one side (medium side) of the paper controller, as shown in FIG. 18, an instruction for instructing a browser program (such as Microsoft Internet Explorer (trademark)) for accessing the Internet is provided on the surface of the paper medium. Is printed as an icon area. On the paper controller, as shown in the figure, a “user (operator) registration” instruction, a cursor movement instruction when browsing the web, a URL copy / link instruction, a registration / display displayed on the display device, An icon area indicating an operation instruction on the editing panel, an instruction to open / close the registration / editing panel, a URL of the registration / editing panel, and an instruction to delete the link is printed. In these icon areas, dot patterns representing respective instruction codes are printed. For example, an interrupt code for moving the screen displayed in the browser program upward is registered in the “upward △” area of the scroll icon area for web browsing, and the browser is displayed in the “downward ▽” area. An interrupt code that moves the screen displayed in the program downward is registered.

  FIG. 19 shows a paper controller for registering an Internet URL as a bookmark. A rectangular area (icon area) in which an English letter G is designed is provided for 9 rows × 11 columns, and dot patterns having different code values are registered in these 99 icon areas. On the right side, an icon region indicating a category is provided in 9 rows × 2 columns.

  FIG. 20 shows a state in which various operations of the personal computer are performed by the scanner (SCN) reading the dot pattern printed on one surface (medium surface) of the paper controller described in FIGS. 18 and 19. It is explanatory drawing.

  The paper controller main body is made of sheet-like paper or synthetic resin, and a printing surface including a dot pattern is formed on the upper surface, and a transparent protective sheet is laminated on the printing surface. It has a laminate structure. Of course, such a protective sheet is not necessarily essential, and the printed surface may be exposed.

  Further, FIG. 21 shows that each icon area of the paper controller described in FIG. 19 has a peelable seal structure and is attached to a system notebook or the like to be associated with voice or music data.

  FIG. 24A shows a local index table provided in the hard disk device (HD) of the personal computer.

  In the local index table, as shown in FIG. 5A, a code number meaning a dot code and an instruction are associated with each other. Specifically, the contents of the index table include an area (first area: “ID (in the figure) for an ID (for a member)” that registers an instruction to be executed when the dot pattern ID registered in the tag is read. (For members) ”, an area that associates the code number converted by reading the dot pattern of the paper controller and the access destination (second area:“ paper controller ”in the figure), and code The area can be divided into an area (a third area: an area indicated as “medium” in the drawing) in which the number and the registration destination of the content are associated.

  For example, as an example of using the first area, when the first digit of the code number is 1 in the read result of the dot pattern of the tag, the central processing unit (CPU), based on the analysis program, By referring to this index table, it is recognized that the information is from the tag. In this case, the dot code management server is accessed to access the dot code management server index table (the management server table shown in FIG. 24B).

  As an example of using the second area, when the code number is 00001 to 00004 or later in the read result of the dot pattern of the paper controller, the file associated with each is accessed.

  For example, as shown in the figure, as an access destination, a drive name, a startup file, and parameters are registered as a set. More specifically, when the dot pattern read from the paper controller is code number 00001, an e-mail application program is associated with this, and a command meaning creation of a new mail is set as a parameter. Yes. As a result, the e-mail program is started, and a new e-mail can be created.

  For example, in the case of code number 00002, activation of the movie player is designated, and player software registered in the personal computer is activated.

  Furthermore, a character string can be directly input from a paper controller in the same manner as a physical keyboard. For example, when a code number 00003 is read, an English letter “A” or “B” is displayed in a specific application. These character codes are input and passed to the application.

  Furthermore, as an example of using the third area, when a dot pattern printed on a mail order catalog (medium) or the like is read and the code number is 00100, access to a URL associated with the code number (Web browsing), program execution, and movie file activation (playback) are performed.

  If the scanner reads the code number and converts it into a code number, and the code number does not exist in the index table, the central processing unit (CPU) accesses the management server via the network.

  The management server is provided with a user database for managing personal information and an index table on the server side (see FIG. 24B). Personal information corresponding to the code number read from the tag is registered in the server-side personal information management table (not shown). For the code number in which 1 is added to the first digit described above, When the personal information is not registered, the central processing unit (CPU) of the management server causes the personal computer to download an initial registration program according to the program. In this initial registration program, the user's own personal information, such as an address, a name, and a telephone number, are input. Based on the personal information input in this way, a user database of the management server is generated.

  That is, by registering personal information associated with a tag in the user database of the management server, authentication processing such as network access and payment can be easily performed.

  In the management server table of the management server, a table similar to the local index table described with reference to FIG.

  This management server table is a table that complements the code number registered in the local index table. When the code number of the result read by the scanner does not exist in the local index table, the management server table is accessed. .

  For example, if the reading result by the scanner is the code number 00100 that did not exist in the local index table, the central processing unit (CPU) of the personal computer accesses the management server via the network according to the program. Refer to the management server table.

  In the management server table, the code number 00190 defines a predetermined URL access (Web browsing), so the personal computer executes an access to the URL (Web browsing).

  If the code number is, for example, 00201, meaning streaming distribution, the distribution server is accessed to download streaming data.

  In this case, the contents of the management server table are downloaded to the index table of the personal computer along with the streaming data.

  Therefore, after that, even if the reading result from the scanner is the code number 00201, the personal computer can process only the local index table without accessing the management server table.

  25 to 28 are diagrams for explaining another embodiment of the paper controller.

  The paper controllers shown in these drawings are substantially the same as the paper controllers described with reference to FIGS. 18 to 20, except that a guide bank is provided for each predetermined icon area.

  As shown in FIG. 27, the guide bank is a rib-shaped bank guide in which a plastic plate is further provided on the upper layer of the paper controller main body, and a part of the plastic plate protrudes in the exposed surface direction.

  When this bank guide is slid on the upper sheet surface with the tip of the scanner (lower end in the figure) (translated along the sheet surface), the operator who holds the scanner will see a slight obstacle to the sliding direction. It is preferable that the height is as high as it feels, and it is also possible to get over it intentionally and continue to slide.

  By providing such a bank guide, the operator can place the scanner on the intended icon area even if the operator does not rely on visual observation, if the positional relationship between the bank guide and the icon area on the paper controller body is remembered to some extent. Is possible. For example, in FIG. 25, a maximum of four icon areas (for example, “URL”, “Link”, “All URLs”, “All URLs” in the middle of the left column of FIG. 25) are surrounded by a rectangular bank guide. Link ”), but the user (operator) can print on the paper controller at hand by sliding the scanner in the upper left, upper right, lower left, and lower right directions (to the four corners of the guide bank). Even if the surface is not watched, the scanner can be stopped accurately on each icon area and each code value can be read.

  The guide portion may be provided with a protrusion on the card itself by embossing the card itself. Further, as shown in FIG. 28, the guide may be formed of a separate plastic, and only the card may be interchangeable with respect to the guide.

  FIG. 29 and FIG. 30 are obtained by providing Braille protrusions together with a dot pattern in an area surrounded by the bank guide of this paper controller. By providing Braille and dot patterns in the same area in this way, the same input efficiency as that of a healthy person can be maintained even when a visually impaired user (operator) uses the scanner.

  In particular, in FIG. 30, a dot pattern is printed above a predetermined square area of a medium (for example, paper or a synthetic resin plate) and braille is provided below, and the square area is surrounded by a wall (bank). Therefore, even a visually impaired user can grasp sensuously that different areas are scanned when the tip of the scanner crosses the bank.

  In this embodiment, the area where the dot pattern is printed and the area where the braille is printed are provided separately. However, the present invention is not limited to this, and the dot pattern and the braille are printed in the same area. Of course, it may be.

(Mouse pad)
33 to 39 are diagrams illustrating a mouse pad according to an embodiment of the present invention.

  FIG. 33 is an explanatory diagram showing a mouse pad system that performs various operations of a personal computer by a scanner (SCN) reading a dot pattern printed on one surface (medium surface) of a mouse pad as a medium. .

  This mouse pad is made of sheet-like paper or synthetic resin, similar to the paper controller and paper keyboard described above, and has a printing surface including a dot pattern on its upper surface. It has a laminated structure in which a transparent protective sheet is laminated on top. Of course, such a protective sheet is not necessarily essential, and the printed surface may be exposed.

  As shown in FIG. 34A, the printing surface is composed of an inner peripheral area and an annular outer peripheral area.

  Coordinate values and code A are printed as dot patterns in the inner peripheral area. In the outer peripheral area, the coordinate value and the code B are printed as a dot pattern. When the mouse pad is used for coordinate input, it is possible to input coordinates like a tablet using all the areas in a circle.

  In FIG. 5B, an image area in which alphabetic code values are registered is provided in the outer peripheral area.

  Such a mouse pad does not necessarily have a circular shape, and may have a rectangular shape as shown in FIGS.

  FIG. 35 is a diagram in which the input instruction areas of the personal computer are respectively arranged in the annular outer peripheral area. In each input instruction area, code values for the operation of the computer are printed in dot patterns. It also functions as a mouse pad and the paper controller described above.

If the pull-down menu is displayed, touching the icon (functional area) of (13) and (14) moves the active item of the displayed item up and down.

(15) When the memory display icon is clicked, a list of texts that have been selected or copied or cut out is displayed from the top in the new order. By touching the icons (functional areas) of (11) and (12), the active item can be moved up and down. All text is preserved unless (6) the active item is deleted.

(16) ENTER
When the position of the cursor is moved to a predetermined position and there is an instruction at that position, when the icon (functional area) is touched, the instruction is executed. Kana-Kanji conversion can also be determined. Has the same function as a general ENTER key.

  36 (a) to 36 (d) and FIGS. 37 (a) to 37 (b) show the scroll operation of the web page of the Internet browser program by the operation of the scanner using such a mouse pad.

  FIG. 38A is a plan view of a three-dimensional mouse pad, and FIG. 38B is a cross-sectional view thereof.

  The mouse pad is provided with an annular groove so that an operator who grasps the difference in the area can experience it through the scanner.

  Such grooves may have a radial shape as shown in FIG. 39 in addition to the annular shape shown in FIG.

(Other paper controllers)
FIG. 40 proposes a new keyboard provided with this input reading means.

  Regarding the keyboard layout, the images of the key tops are arranged in a fan shape centering around “H”, “double”, “Y” and “conversion”, “Enter”, and the images of the key tops are arranged in a fan shape in the center direction The key top images are arranged at positions shifted so as not to be arranged in a straight line.

  Each key top image is centered on “H”, “double”, “Y” and “conversion” “Enter”, with vowels (“A” “I” “U” “E” “O”) inside, Consonants (“K”, “S”, “T”, “N”, “M”, “Y”, “R”, and “W”) are arranged on the outside thereof.

  On these key top images, a dot pattern registered in the same format as the code value and the XY coordinates as shown in FIG. 9B is superimposed and printed.

  The XY coordinates may be defined independently for each icon, or the XY coordinates may be defined over the entire medium surface.

  By using this keyboard, it is possible to input characters by touching and releasing the medium surface with a scanner (SCN). For example, to input “umbrella”, first, the key top image portion of “K” is read by the scanner. Then, the scanner (SCN) is traced (slid) on the paper keyboard in the order of “A” → “S” → “A”. Such an operation between the key tops can be recognized by a change in the coordinate value of the dot pattern superimposed and printed on the medium. Thereafter, the scanner is released (lifted up) from the key top image of the last “A”. The central processing unit (CPU) of the personal computer recognizes the input of “KASA” for Roman characters input by the recognition program and the “conversion instruction” by the release operation, and the application program (Japanese input program for the personal computer). ). As a result, “umbrella” is displayed in Chinese characters at the cursor position on the display device. In addition, if it is desired to convert input characters into Japanese, “conversion” may be read by a scanner.

  If the user wants to input “patent” (see FIGS. 42 (1) to (5)), first read the key top image portion of “T” with a scanner and slide it as it is to “O” → “K”. ”→“ Double ”→“ Y ”→“ O ”, and release (pull up) the scanner from the key top image of the last“ O ”or slide to“ Convert ”. Here, “double” is an area read by the scanner when the previous character is input twice in succession. The central processing unit (CPU) of the personal computer recognizes that it is a “conversion command” by input of “TOK (double) YO” in Roman characters, release operation, or subsequent reading of “conversion” by a recognition program. To an application program (Japanese input program) such as a personal computer. As a result, “patent” is displayed in Chinese characters at the cursor position on the display device.

  FIG. 41 shows a list of rules for Japanese conversion, but this is not a limitation.

  FIG. 43 shows an application as an auxiliary device for voice reading.

  This figure shows a system for assisting Japanese input by voice. When a user (operator) speaks through a microphone, a central processing unit (CPU) of the personal computer analyzes voice information input from the microphone and displays conversion candidates on a display device. Here, a case where the user (operator) utters “Ishi” is shown. Conversion candidates corresponding to the utterance of “Ishi” are displayed on the display device as “1 intention”, “2 stone”, “3 will”, “4 doctor”, and “5 will”.

  Here, the user (operator) selects a number from the candidates displayed on the display device, and scans the icon area (for example, “2”) of the number of the paper controller (paper keyboard) with the scanner. A dot pattern in which each number is coded is printed in the icon area of these numbers, and the coded number is input to the personal computer by the operation of the scanner. The central processing unit (CPU) of the personal computer reads a number associated with the input candidate from the input code, and delivers a conversion character (for example, “stone”) corresponding to the number to the application program.

  44 to 56 show an example in which a paper keyboard is used as input means of the infrared remote controller.

  In these, the scanner is integrated with the remote control. FIG. 44 (a) shows the structure in which the scanner is provided at the tip of the remote control, and FIG. 44 (b) shows the surface on the side opposite to the operation panel of the remote control. The structure provided with the scanner is shown.

  A user (operator) scans a radio / television column such as a newspaper using a scanner of a remote controller. In the newspaper TV column, channels and broadcast stations are displayed in the XY direction, and the program name, performers, and contents are printed in text information. In such a radio / TV column, a viewing / recording reservation code is printed as a dot pattern. By scanning this dot pattern with a scanner, the reservation code assigned to each program is read by a remote controller and set top The transmission is made toward the box (STB) or the infrared receiver of the television main body.

  FIG. 45 shows a remote controller having a structure in which a scanner can be placed on a cradle (base), and a central processing unit (CPU) that generates an infrared signal by analyzing a read signal from the scanner and a power source (BAT) in the cradle. Is built-in.

  FIG. 46 is an explanatory diagram in the case where program reservation / recording is performed for a set-top box for CS broadcasting or Internet broadcasting using the scanner (SCN) and cradle of FIG.

  The connection between the scanner (SCN) and the cradle may be performed wirelessly in addition to the wire shown in FIGS.

  47 shows an example of a paper controller used for the remote control shown in FIGS. 45 and 46, and FIG. 48 shows an example of a paper controller used for a remote control with a set top box as a control target.

  49 to 56 are associated with execution instructions of the television (TV) or set-top box, which means the code value of each functional area (area where dot pattern is printed, icon) of the paper controller shown in FIG. Is.

  For example, when the “power” area printed on the cover of FIG. 47 is read with a scanner, the dot pattern printed on the area is read and converted into a code value, and a power-on signal is sent to the TV or set-top box. Sent to.

  FIG. 57 is an implementation of the paper controller of the present embodiment as a medium for controlling a set top box provided in a guest room in a hotel.

  On this paper controller, symbols are printed for English, Chinese, Korean, and Japanese, and a dot pattern is printed on each symbol. A control signal is output from the remote control as radio or optical communication so that the set-top box performs an operation that each symbol means.

  58 and 59 show an example of a paper controller (paper keyboard) in the case of controlling music or a video player. Although detailed explanation of the music / video player is omitted, video and audio can be recorded and reproduced using the scanner (SCN) and these paper controllers (paper keyboard) in the operation of the music / video player. It is. A dot pattern is also input to each command area of these paper controllers (paper keyboard). Further, as shown in FIG. 59, a paper controller (paper keyboard) capable of inputting characters may be prepared.

  FIGS. 60 to 67 are associated with execution instructions of the music / moving image player, which means the code value of each functional area (area on which the dot pattern is printed, icon) of the paper controller shown in FIGS. is there.

  68 to 70 show a case where a white board is used as the medium surface, and a dot pattern is also printed on the white board. It is assumed that the dot pattern on the whiteboard is printed with a dot code (see FIG. 9) that means a coordinate value.

  As shown in FIG. 70, a predetermined image is projected and displayed by a projector on a whiteboard on which a dot pattern representing coordinate values is printed. The projector is connected to a personal computer (not shown). When the scanner of the present invention (see FIG. 1) connected to the personal computer is used to operate any position on the whiteboard, the dot pattern at that position is changed to the scanner (SCN). ) And converted into coordinate values in the personal computer. In the hard disk device in the personal computer, an index table (see FIG. 24) in which coordinate values and instructions or addresses are associated with each other is referred to, and information display and instruction execution specified for the corresponding addresses are performed. It has become.

  In this whiteboard, as shown in FIG. 69, an adhesive layer is provided on the surface of the whiteboard, and a transparent sheet on which a dot pattern is printed is pasted with the dot pattern as the adhesive layer side. ing.

  Therefore, since the dot pattern itself is protected by the transparent sheet, the dot pattern itself does not deteriorate even if the tip of the scanner comes into contact with the pen tip for the whiteboard.

  In the example of FIG. 70, when the dot pattern on the area where the icon is displayed on the whiteboard is read by the scanner, the dot pattern is converted into a coordinate value on the personal computer and registered in advance corresponding to the coordinate value. The application program that is being started is started.

  As shown in FIG. 68, an image of the remote control may be projected on the left side of the whiteboard, and a moving image controlled by the remote control may be played on the right side.

  In this case, when the portion corresponding to the projected image of each button of the remote control is read by the scanner, the coordinate value is read into the personal computer and the operation corresponding to the coordinate value, for example, playback, fast forward, rewind, pause Etc., and the projection moving image (image) can be controlled.

  FIG. 71 shows an example in which a board is a translucent acrylic board (screen board) instead of a white board, and a personal computer desktop screen or video (image) is projected from the rear by a rear projector. .

  In this screen board, an infrared cut filter sheet is attached to the rear projector side of the acrylic board via an adhesive layer, and a transparent sheet is attached to the opposite surface via an adhesive layer. And the dot pattern which means a coordinate value is printed on the adhesive layer side of the transparent sheet.

In this way, since the infrared cut filter sheet is attached to the rear projector side of the screen board, the infrared component in the irradiation light from the rear projector is cut, so the infrared component from the rear projector is placed on the scanner side. The noise light does not reach. Therefore, it is possible to maintain high dot pattern reading accuracy.
In FIG. 71, when the icon portion of the browser program is photographed by the scanner, the coordinate value is a correspondence table in which coordinates and processing instructions are paired by the central processing unit (CPU) of the personal computer (not shown). ), It is recognized that the position is the icon placement position of the browser program, and a processing command (in this case, activation of the browser program) corresponding to the coordinates is executed.

  In FIG. 73, in order for the user (operator) to create the paper keyboard described above, the image information of the paper keyboard is edited on the screen, for example, a mask is formed by cutting a mask in a part of the area, This is an example for creating a paper keyboard that can be used by a user (operator) by freely arranging dot pattern codes on a mask.

  Prepare a program that allows you to delete, add, and arrange function icons yourself with the application on the screen, and print the image of the screen with the dot pattern or print it on the paper on which the dot pattern is printed. As a result, the execution instructions for the functions of application programs such as a word processor and spreadsheet software can be realized by a paper keyboard that is customized and printed for its own use.

  As a result, the arrangement of function buttons on the screen can be reduced, and the screen interface of the word processor, spreadsheet, and application program can be made extremely simple.

  74 and 75 show an embodiment in which the dot pattern reading device described above in this embodiment, an index table, a server management table, and the like are applied in the form of a distribution material as a technical introduction.

  As shown in the distribution materials (FIGS. 74 and 75), the present technology can be realized as Grid Onput (trade name).

  74 and 75 show a case where a scanner is used as GAM (Grid Application Manager, where GAM is the name of an application program installed in a hard disk device of a personal computer) and a personal computer (PC) as hardware. This is an example.

  In the figure, (1) to (5) and (7) show actual operation examples. That is, as shown in (1) of FIG. 74, the user executes an installation program downloaded by accessing a CD-ROM or Internet distribution server on a personal computer (PC), and GAM is executed on the OS (operating system). And register the driver program as a resident program. In addition, the application program bundled in the GAM and content data such as images and moving images are also installed in the hard disk device (HD).

  Next, when the scanner is connected to the USB terminal, the resident driver program recognizes this.

  Next, when the surface of the tag is read by the scanner, the captured image (dot pattern) is read into a personal computer (PC) via a USB cable and developed in a video memory (VRAM). The GAM read into the central processing unit (CPU) is decoded from the captured image (dot pattern) into a code (code number) according to the algorithm (GRID1 or GRID2) described above.

  Here, when the tag is scanned for the first time by the scanner, a screen prompting the user to input personal information corresponding to the tag is displayed on the display device (DISP) of the personal computer (PC). Register personal information such as address, credit card number, etc. The personal information input in this way is registered in the management server table shown in FIG. 24 and used for subsequent authentication.

  That is, after that, when the personal computer (PC) is activated, the tag is scanned by the scanner to perform authentication at the management server. When this authentication is completed, the GAM is activated.

  Next, a paper medium or a paper controller (paper keyboard) on which the dot pattern is printed is scanned (read) by the scanner, so that the dot pattern is photographed and photographed image data is input to the personal computer. A dot code (code number) consisting of a 32-bit numeric string is decoded.

  Based on this dot code (code number), a GAM dot code management table (index table) is referred to.

  If the dot code (code number) is already registered in the index table, it is recognized that the content data is already installed in the personal computer (PC), and the content data is read out. Played. If the content data is a moving image or image, the movie or image is displayed on the display device (DISP) by a moving image reproduction application program or image display program corresponding to the content data.

  In addition, when an Internet address (URL) is registered in the dot code (code number) of the index table, a browsing program (Microsoft Internet Explorer, etc.) is activated to access the address. .

  By the way, as shown in (5) of FIG. 74, when the dot code (code number) as a result of reading the dot pattern is not registered in the local (in the personal computer) dot code management table (index table), the Internet It refers to the dot code management server above. Here, if a dot code (code number) is registered in the management server table of the dot code management server, according to the instruction (command) for the dot code (code number), the specified web server (1 ) Download content, specifically download content from server A, (2) Stream video distribution, specifically data distribution from server B as streaming distribution server, (3) Web browsing, specific Download of the Web file designated by the address (URL) of the server C is automatically started.

  Next, when content data is downloaded to a personal computer (PC), additional data (a code number and an address) are paired with the content data in a dot code management table (index table) for starting the content data. Data) is also downloaded and thereafter managed by a dot code management table (index table) in the personal computer.

  Therefore, after that, when the same code number as described above is read, the server A, B or C on the Internet is not accessed again, and the dot code management table (index table) including newly added data is stored. Based on this, the content data downloaded in the hard disk device (HD) of the personal computer is reproduced.

  76 and 77 illustrate an example in which the paper controller is used in an order system of a restaurant such as a restaurant.

  As shown in the figure, each table of a restaurant has a menu in which a dot pattern with a different code number is printed for each menu item, and a computer terminal having a display device (DISP) at one end of the table Is installed.

  The scanner incorporates a short-range wireless communication system such as Bluetooth, and the code number and the number information read from the menu can be transmitted to and from the computer terminal.

  The code number and the number information corresponding to the menu item read from the scanner are transmitted to the computer terminal. A central processing unit (CPU) in the computer terminal generates an order signal in which a table number is added to the code number and the number information of the menu item, and transmits the order signal to the order server.

  The order server extracts the table number, the code number of the menu item, and the number information from the order signal, and sets the order for the kitchen. Specifically, a menu item corresponding to the table number and code number and the number thereof are displayed on the display device displayed in the kitchen so that the person in charge of the kitchen can prepare for cooking.

  The table number is added in the computer terminal when generating the order signal. However, a sticker or the like on which the dot pattern indicating the table number is printed on the surface of the stand of the computer terminal or the surface of the table in advance. When the scanner is distributed on the table, the table number and the computer terminal are related by reading the surface of the seal with the scanner.

  Therefore, a plurality of scanners may be distributed on the table so that orders from a plurality of people can be received simultaneously.

  FIG. 84 shows an example of a paper keyboard using XY coordinate values as a mouse pad.

  FIG. 84A shows a mouse keyboard area provided on a part of a paper keyboard.

  In this embodiment, only the code value is registered in the dot pattern printed on the key top image, and the code value and the XY coordinate value are registered in the dot pattern printed on the mouse pad area. When the user slides the scanner upward in the mouse pad area, the screen is scrolled upward. Similarly, when the scanner is slid downward, the screen is scrolled downward. The same applies to the right direction and the left direction.

  FIG. 84B uses the entire paper keyboard as a mouse pad area.

  In this embodiment, both the code value corresponding to the contents of the key top and the coordinate value are registered in all the key top images. When the user taps the scanner twice or more at an arbitrary position on the paper keyboard and then slides the scanner upward, the screen is scrolled upward. Similarly, when the scanner is slid downward after tapping the scanner twice or more, the screen is scrolled downward. The same applies to the right direction and the left direction.

  In FIG. 85, in the dot pattern formed on the projection board, the coordinate value and the code value are defined in one dot pattern format, a predetermined matrix section is formed on the board, and the same pattern is formed. In the matrix section, the same code value is given regardless of the change of the coordinate value.

  In this embodiment, the icon image is arranged over one or a plurality of matrix sections, and the dot pattern of the icon image is read by the reading unit, thereby controlling the video corresponding to the icon image or starting the program. Is instructed.

  FIG. 86 shows the relationship between the dot pattern code value and the XY coordinate values in each matrix of the whiteboard.

FIG. 86A shows a table of values defined in 32 bits from C _{0 to} C ₃₁ of the dot pattern. As shown in the figure, C _{0 to} C ₇ mean Y coordinate, C _{8 to} C ₁₅ mean X coordinate, C _{16 to} C ₂₉ mean code value, and C _{30 to} C ₃₁ mean parity.

  These numerical values are arranged in the lattice region shown in (b), and (c) shows a specific dot pattern.

  FIG. 87 shows a code value / command correspondence table provided in a hard disk device (HD) of a personal computer. For example, when the dot code corresponding to the dot pattern read by the scanner is 11 or 12, the reproduction of the video is stopped. If the dot code is 13, playback is paused.

  88 to 90 are diagrams for describing a technique for creating a paper keyboard on which icons of a desktop screen are printed by capturing and printing the desktop screen.

  In this embodiment, when a desktop screen is captured by pressing a “print screen” button (prt sc) on a keyboard (KBD), an icon is printed together with a dot pattern on a paper surface. A program to be output as is prepared.

  FIG. 88 (a) shows a desktop screen of a display (display means). For example, a word processor, the Internet and a spreadsheet icon image and a start button are displayed on the desktop screen.

  When the desktop screen is captured, the hard disk device (HD) of the personal computer recognizes where the icon is displayed on the desktop screen and calculates the coordinate value of the position where the icon is displayed. Then, the XY coordinates of the desktop and the XY coordinates of the printing paper are made to correspond to generate a dot pattern corresponding to the icon. In this dot pattern, a dot pattern that represents coordinate values on the screen and a code value that represents the function of an icon are included in one format. Then, a superimposition printing process of the desktop screen image and the generated dot pattern is performed. FIG. 88 (b) is a diagram showing a paper keyboard on which a desktop screen and a dot pattern are printed.

  FIG. 89 is a diagram illustrating a table indicating the correspondence between code values and activation programs. When the dot pattern is generated by the above-described processing, a table in which the code value of the dot pattern is associated with the activation program (icon function) meaning the icon is generated in the hard disk device (HD). For example, when a dot pattern corresponding to an icon indicating a word processor is generated and a code value 0001 is assigned, the code value 0001 and the activation program Warpro. A table corresponding to exe is generated. The same applies to icons indicating the Internet and spreadsheets. By creating such a table, for example, when the user clicks on the picture of the graph of the paper keyboard shown in FIG. 88B with the scanner, the spreadsheet program is started.

  FIG. 90 is a diagram showing the dot pattern format described above. Since the dot pattern format is the same as that described above, a description thereof will be omitted.

  In this way, the icons can be easily specified by printing the icons on the desktop screen in advance. For example, even if the icons on the desktop are hidden from the screen due to the activation of multiple programs, the program can be easily started by clicking the icon image with a scanner on the printed paper keyboard. It is possible to raise.

  The present invention can be used for an input system of information processing equipment such as a personal computer, a television, and a music player.
