Abstract

PURPOSE:To display the menu displaying using an input indicator near a cursor by checking whether or not the menu area can be assigned concerning the upper, lower and right, left areas based on a cursor position, specifying one of them as a menu area and executing the menu displaying. CONSTITUTION:A menu displaying area is assigned based on the cursor position of an input character instruction and the menu displaying is executed to the assignment position. When the menu area based on the cursor position is assigned, it is judged concerning the upper and lower and right and left of the cursor position by calculation whether or not the menu area enters and optimum one of the upper and lower and right and left is specified as the menu area. Thus, by using the input indicator to unify the input displaying, a menu can be displayed near the input character.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an input display in which an input and a display are integrally stacked, and particularly to a menu display device using this input display.

[Conventional technology]

A conventional example is JP-A-58-184644. This Japanese Patent Laid-Open No. 58-184644 has a CRT, and has a plurality of input areas on its display surface, and the areas are moved according to the position of screen display data. Thus, the two CRs
This has the advantage of requiring only one CRT instead of the T.

[Problem to be solved by the invention]

JP-A-58-184644 is an example using a CRT, and is not intended for an input display device with an integrated input display.

SUMMARY OF THE INVENTION An object of the present invention is to provide a menu display device using an input display that displays a menu near input characters by using an input display integrated with an input display.

[Means to solve the problem]

In the present invention, a menu display area is allocated based on the cursor position of an input character instruction, and the menu is displayed at the allocated position. When allocating a menu area based on the cursor position, it is determined by calculation whether a menu area can fit in the upper, lower, left, or right sides of the cursor position, and the optimal one of the upper, lower, left, and right areas is specified as the menu area.

[For production]

According to the present invention, it is checked whether menu areas can be assigned to the upper, lower, left, and right areas based on the cursor position, one of the areas is specified as a menu area, and the menu is displayed.

〔Example〕

FIG. 2 shows an overall configuration diagram of the present invention. The input display device 1 has a liquid crystal display surface and a transparent sensing surface for pen press input, which are laminated together. A pen 2 can be pressed on the transparent sensing surface, and when an operator letters a character with the pen 2, the normalized character can be displayed on the liquid crystal display surface.

The information processing section 4 takes in the pressed characters as a signal from the transparent sensing surface and recognizes the pressed characters. The recognized characters are normalized as characters and displayed on the liquid crystal display screen corresponding to the pressed location. That is, when a character is handwritten on the sensing surface, the character is recognized and normalized, and the normalized character is displayed at a position corresponding to handwriting.

In addition to this character recognition, the information processing device 4 includes a buffer for storing recognized characters and character editing function means.

The printer 5 prints edited text and the like in response to a print instruction.

FIG. 3 shows a longitudinal cross-sectional view of the input display 1. As shown in FIG. This input display device 1 includes a liquid crystal display surface 7 and a transparent sensing surface 6 for pen press input.
are laminated and integrated. Since the sensing surface 6 is transparent, there is no problem in viewing the display on the liquid crystal display surface from above. Further, the liquid crystal display surface 7 and the sensing surface 6 have various electrodes, but these are omitted in the drawing. When handwriting is pressed with the pen 2 on the input display 1, the pressed position can be extracted as an electrical signal, which is input by the processing device 4 and used for character recognition.

FIG. 4 shows an example of the display state of the input display. In the figure, an example is shown in which alphabets are input in the order of A-)84C→... and normalized A, B, C,... are displayed. If the pen 2 is present at the latest input position on the display screen and one handwriting is in progress, displaying the menu display area at a position closer to the position of the pen 2 can simplify menu instructions. Therefore, in this embodiment, as shown in FIG. 3, the menu 3 is displayed on the lower right side near the position of the pen 2 (cursor display).

Here, menu 3 means various editing instructions, and in the figure, "insert", "delete", and "convert".

One menu was composed of four instructions: "full-width/half-width". Of course, there are other types on the menu as well.

The display position of the menu varies depending on the current character input position. FIG. 5 shows an example. The figure on the left is an example of the first line being displayed; in this case, a menu area is set at the bottom right of the most recently input character position. The middle diagram shows an example of the menu displayed when the display of the first line is almost completed, and the menu area is set at the bottom. The figure on the right is an example of a display after the display has finished covering most of the display screen, and is an example in which a menu area is set and displayed at the top of the latest row.

The above settings as shown in FIG. 5 are automatically performed according to calculation results automatically determined based on the cursor position (latest input character position).

FIG. 1 shows a processing flowchart for menu area allocation. This processing is performed by the processing device 4, and the prerequisites necessary for understanding it are shown in FIG.

In Figure 6, the size of the display screen is 0, where length x width = QXm.
The display screen starts at (1,1) in the upper left, and (1, 1) in the lower right.
Q, m) was set as the end position. The size of the menu area is
Length x width = n, Xn.

nl and n2 were fixed. Latest input character position (x t
It is assumed that the cursor 10 is displayed at y).

The first VjA will be explained. When instructed to display the menu,
The process shown in FIG. 1 begins. First, in step 11, it is checked whether the menu is on the right side at the current cursor position (xty). How to check this?

m −x > n z・・・・・・・・・・・・(1
), and if formula (1) is satisfied, the menu can be displayed on the right side and the process moves to step 11.

If formula (1) does not hold, the menu cannot be displayed on the right side, and the process moves to step 15.

Step 12 checks to see if the menu is below the cursor position. This check method follows the formula (2), where Q-y>n, and if formula (2) is satisfied, the menu can be displayed at the bottom. , proceed to step 14.

If formula (2) does not hold, the menu cannot be displayed at the bottom, and the process moves to step 13.

In step 14, the display position of the menu is calculated. Specifying the display position of the menu means specifying the top left top position of the n□×n2 menu area, and step 14
Now, calculate m−n2 and y+i, and find this locus JR (
m-n2. y+1) was set as the menu display position. Here, setting (y+1) instead of y means that the menu display position has been moved to the next position after the cursor position.

In step 13, the menu position is calculated based on the result of step 12. That is, calculate m-n2 and y-1-n, and calculate this coordinate (m nil y 1-n□)
Let be the menu position. Here, y-1-n means that since there is no menu display area below the current cursor position, the position one line before the current cursor position should be the last line of the menu, and the first position of the menu display. Calculated.

In step 15, a check is made to see if the menu is below the cursor position. This checking method is α-y>n (3). If the formula (3) is established, it can be displayed at the bottom and the process moves to step 16. If formula (3) does not hold, it cannot be displayed on the lower side, and the process moves to step 17.

In step 16, the menu display position is calculated in response to equation (3) being satisfied in step 15. That is, (mn −)
/ z and y+1 are calculated and this coordinate ((m
nz)/2t y + 1) as the menu top coordinates. Here, (m-n,)/z is used because the menu cannot be inserted on the right side, so the difference between m in one display and the menu width n2 is calculated, and the position half of this difference is set as the start position. This is because of this. Furthermore, the reason why the cursor is set to y+1 is that the starting position is set to the line next to the current cursor position y.

In step 17, in response to the failure in step 15, a new menu top position is calculated. That is, (m-T1.
)/2 and (y-1-n□), and calculate the coordinate ((m
-nz)/z+YLnx) is set as the top position of the menu. The reason for (m-n2)/z and (y-1-n) here is step 16. This is the same as step 13.

In step 18, step 13 is determined according to one condition.
．． Import the menu top display position of 14.16.17,
A menu of size n, Xn is displayed at this top position.

In the above example, if there is enough display space on the right side and bottom,
Although the menu is displayed on the right side at the bottom, it may be displayed on the right side itself. However, if it is on the right side and in the lower row, it has the advantage that the menu can be displayed without overlapping with the current display position. Furthermore, if the present invention is generalized, the menu display position is set in the vicinity of the current cursor position. Needless to say, the neighborhood definition and neighborhood calculation algorithm can be easily set.

〔Effect of the invention〕

According to the present invention, a menu can now be displayed near the cursor using the input display.
