Embodiment
In order to make the object of the invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
The theory diagram of the input media of the electronic equipment that the embodiment of the invention provides is as shown in Figure 2, comprises gravity sensing module, data sampling module, data conversion module, character recognition module and input function On/Off module.Wherein:
Input function On/Off module links to each other with data sampling module, is used for controlling the On/Off of the input function of electronic equipment input media; During concrete the realization; Input function On/Off module comprises button and corresponding control circuit, and when button was pressed, input function On/Off module output control signal was given data sampling module; Data sampling module is sampled to the motion trace data of gravity induction module output; When button was released, input function On/Off module output control signal was given data sampling module, and data sampling module stops the motion trace data of gravity induction module is sampled;
The gravity sensing module links to each other with data sampling module, is used for the motion of induced electricity subset, to the motion trace data of data sampling module output electronic equipment, like the acceleration information on three dimensions X, Y, three directions of Z; When the user need import electronic equipment; Can hand-hold electronic equipments, press the button of input function On/Off module, the motion of control electronic equipment; Electronic equipment is used as pen paddling aloft; The movement locus respective user of electronic equipment is wanted the character imported, and the motion of gravity sensing module induced electricity subset is to the motion trace data of data sampling module output electronic equipment;
Data sampling module links to each other with data conversion module, is used for the motion trace data of the electronic equipment of gravity induction module output is sampled, and obtains the three-dimensional coordinate data of electronic equipment when each sampled point; The three-dimensional coordinate data that data sampling module is obtained sampling is transferred to data conversion module;
Data conversion module links to each other with the literal identification module, is used for converting the three-dimensional coordinate data of electronic equipment movement locus to two-dimensional coordinate data, and the two-dimensional coordinate data generation movement locus image according to conversion is transferred to character recognition module with the movement locus image;
Character recognition module is used for identifying corresponding characters according to trace image.
Specifically, the gravity sensing module can be sensed the acceleration of gravity of electronic equipment on X, Y, three directions of Z, and data sampling module can calculate the movement locus of electronic equipment in view of the above.At first, suppose that electronic equipment has moved a segment distance S aloft, institute's spended time is T, and this segment distance possibly not be the straight line of rule, and possibly be one section relatively more crooked line, and is corresponding with the stroke of numeral, letter and Chinese text etc.According to the infinitesimal analysis principle; If time T is more little; Then the track of S then possibly can reach desired precision as long as can guarantee this time T, such as 0.1 second near straight line more; Track in this inner electronic equipment motion in 0.1 second can be regarded as rectilinear motion basically, just can very simply calculate this section track S.So in very long a period of time, the geometric locus of electronic equipment motion is divided into some very little parts according to the principle of infinitesimal analysis, and then the summation of all some very little distances is the track of electronic equipment motion.
In practical application; When the button of input function On/Off module is pressed; The controlled instruction of data sampling module begins sampling, gathers the electronic equipment motion trace data that the gravity sensing module is obtained at each sampled point, mainly is X, Y, last acceleration of gravity and the angle value of Z; Thereby the three-dimensional coordinate data of electronic equipment when confirming this sampled point, data sampling module is transferred to data conversion module with the three-dimensional coordinate data of the electronic equipment of each sampled point sampling.As, set an initial coordinate point (0,0,0), this point is the starting point of electronic equipment motion; Gather the three-dimensional coordinate data of electronic equipment again at next sampled point T1 then, thus the coordinate when drawing this sampled point (X1, Y1, Z1); Sample at next sampled point T2 then, thereby the coordinate when drawing this sampled point (X2, Y2, Z2) ...; When the Tn sampled point, sample electronic equipment three-dimensional coordinate data (Xn, Yn, Zn) ..., until the electronic equipment stop motion till.
Three-dimensional coordinate figure as shown in Figure 3, X, Y, Z are respectively three-dimensional direction among the figure, and A1 is the three-dimensional motion curve of electronic equipment to Ai among the figure; Theoretical according to infinitesimal analysis, this section movement locus is divided into some segment tracks, as long as the sampled point time is enough little; Then this segment distance can be regarded as straight line; And because the time is enough little, then can think the uniform acceleration motion in this segment distance, move for uniform acceleration; Distance equals result that acceleration multiply by time square again divided by 2, that is: S=A T
2/ 2.Wherein, S represents distance, and A represents acceleration, the time of T representative motion (two sampled point between the time interval).The gravity sensing module is sensed the acceleration of gravity (be A) of electronic equipment in X, Y, three directions of Z, and data sampling module can calculate the three-dimensional coordinate data of electronic equipment at each sampled point according to this formula.
Corresponding to the track among Fig. 3, can obtain following data:
At T1 constantly, the three-dimensional coordinate of electronic equipment be (X1, Y1, Z1);
At T2 constantly, the three-dimensional coordinate of electronic equipment be (X2, Y2, Z2);
At T3 constantly, the three-dimensional coordinate of electronic equipment be (X3, Y3, Z3);
At T4 constantly, the three-dimensional coordinate of electronic equipment be (X4, Y4, Z4);
......
At Ti constantly, the three-dimensional coordinate of electronic equipment be (Xi, Yi, Zi);
During concrete the realization, the interval between each sampled point can dwindle as far as possible, promptly increases sampling number, to guarantee the precision of data.
As stated; What the data sampling module sampling obtained is three-dimensional coordinate data; And character recognition module mainly is to be directed against two-dimensional coordinate data; Therefore, data sampling module is transferred to data conversion module with three-dimensional coordinate data, converts three-dimensional coordinate data to two-dimensional coordinate data by data conversion module.Concrete conversion can be adopted following scheme: user's hand-hold electronic equipments is aloft during paddling; The movement locus of electronic equipment needs the stroke of input character corresponding with the user; Then electronic equipment basically just relative to a plane move; So from the three-dimensional coordinate analysis, must have the coordinate data amplitude of variation of one dimension wherein less relatively, curve projection that therefore can this three-dimensional coordinate data is corresponding is to the vertical plane of the less relatively one dimension coordinate axis of this amplitude of variation.For example among Fig. 3, Z1 to the amplitude of variation of Z4 less than X1 to X4 and Y1 to Y4, then with the curve projection of three-dimensional coordinate data correspondence to the vertical plane of Z axle; Obtain the two dimensional surface coordinate data that constitutes at X, Y behind this curve projection, as coordinate A1 (X1, Y1); A2 (X2, Y2), A3 (X3, Y3), A4 (X4; Y4) ..., Ai (Xi, the two-dimensional coordinate data shown in Yi).In addition, data conversion module also is used for generating corresponding movement locus image according to the two-dimensional coordinate data after the conversion, and the movement locus image is transferred to character recognition module.
Image recognition goes out character to character recognition module according to movement locus, comprises Chinese character, letter and number etc., and this recognition technology has been ripe prior art, and this does not give unnecessary details.
Concrete when realizing technical scheme provided by the invention, the beginning of pressing/unclamping corresponding data sampling respectively of the button of input function On/Off module/stop, the time interval of the intermittence sampling of pilot process can be controlled by system.But consider the singularity of character, like Chinese character, a lot of strokes of same word are independently, also need be relatively independent between the different Chinese characters, and the user is when the motion of control electronic equipment, and the movement locus of electronic equipment but is continuous.If in the sampling process to the movement locus of electronic equipment, do not treat with a certain discrimination, the movement locus image that then is transferred to character recognition module will be a disjunctor, and the identification difficulty of character recognition module will be very big like this, and the speed of identification and efficient will reduce.As shown in Figure 4, for the user imports the situation of cursive script character, because the cursive script input all is to connect pen; Use simple and convenient, in the time of (1) point, push button the movement locus of opening entry electronic equipment; When running to (2) point, unclamp button, then judge a character input completion.
For reducing the difficulty of character recognition module identification; Concrete when using technical scheme provided by the invention; Can input function On/Off module be connected with data conversion module, the button of input function On/Off module is pressed or when unclamping, will transmits control signal to data conversion module; A threshold value T0 is set in system simultaneously, and system is used for the operation of control data modular converter according to this threshold value T0.
Specifically, when the user need import a character, at first press the button of input function On/Off module; When if the user imports, employing be cursive script, each stroke of character connects pen; Then after each stroke input is accomplished; Short time is unclamped the button (the released lasting time of this button is less than threshold value T0) of input function On/Off module, then system default this moment button to unclamp be the transition between the different strokes of same character, be not that a character input is accomplished.In the time period that this button was unclamped by the short time, data sampling module keeps the sampling to gravity induction module output data, and the three-dimensional coordinate data that sampling obtains is transferred to data conversion module.Data conversion module is owing to receive the control signal that input function On/Off module is sent; In the time period of unclamping in the button short time; Stop to convert three-dimensional coordinate data to two-dimensional coordinate data, also stop to generate the movement locus image according to two-dimensional coordinate data.Like this, the company's pen (transition stroke) between the different strokes of same character then can not be embodied in the movement locus image of last generation.When the user imports all strokes of a character when finishing; Unclamp button (the released lasting time of this button is greater than threshold value T0); Then all the stroke inputs of character of the system default released representative of button this moment are accomplished; Data sampling module stops the sampling to gravity induction module output data, need import character late up to the user, when pushing button again till.。
Fig. 5 A is an electronic equipment actual motion trajectory diagram, and Fig. 5 B is the last electronic equipment movement locus image that generates, in Fig. 5 B; Because the short time was unclamped button when the user accomplished at each stroke of same character, pushed button during like point (1), unclamped button during point (2); Push button at point (3) then, unclamp button during point (4), point is pressed when (5); Point (6) is to unclamp; Point is pressed when (7), and point unclamps when (8), as long as the time interval that pushed button next time after guarantee point unclamped is less than above-mentioned threshold value T0.Behind point (8), unclamp button, when the duration that continues reaches threshold value T0, then judge the input completion.Fig. 6 is an embodiment of the invention process flow diagram, specifically comprises following step:
1, press the button of the input function On/Off module of electronic equipment, the control electronic equipment is paddling aloft;
2, the gravity sensing module is sensed the motion trace data of electronic equipment, and the motion trace data of sensing is transferred to data sampling module;
3, data sampling module is sampled to the motion trace data of electronic equipment, obtains the three-dimensional coordinate data of electronic equipment at each sampled point, and three-dimensional coordinate data is transferred to data conversion module;
4, data conversion module converts three-dimensional coordinate data to two-dimensional coordinate data;
5, input is accomplished, is the button of input function On/Off module released? If change step 6, otherwise change step 2;
6, data conversion module generates trace image according to the two-dimensional coordinate data after changing, and trace image is transferred to character recognition module;
7, character recognition module identifies the trace image corresponding characters.
The electronic equipment input media that the embodiment of the invention provides can become an integral body with electronic device design, and for little electronic equipment, like mobile phone etc., the user can directly control the motion of electronic equipment, accomplishes the input of character by this, and is of the above embodiments; Also can the electronic equipment input media be designed to independently parts, be connected through wired or wireless mode with electronic equipment, the user is when input character, and only need controlling independently, input media gets final product.
