DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a data input device according to the present invention will be described below with reference to the drawings.

[First Embodiment] In this embodiment, an electronic organizer is used as a data input device. FIG. 1 is a diagram showing an external configuration of a pen-input type electronic notebook equipped with a data input device. The electronic notebook 11 is large enough to be held by the user with one hand, and a touch panel 12 is provided at the center of the electronic notebook 11 main body.

The touch panel 12 has an input area 12.
a and an output (display) area 12b. The input area 12a is an area for performing a handwriting input operation using a touch pen. The output area 12
b is an area for displaying input data determined by a conversion process or the like. In the vicinity of the touch panel 12, there is an electronic notebook 1
1 is provided with a power key 15 for turning on the power.

FIG. 2 is a block diagram of the electronic organizer 11. This electronic organizer 11 has a tablet 1 as an input device.
4. The liquid crystal display device 13 is provided as an output device. More specifically, the input device includes a tablet controller 21, a coordinate detecting unit 22, and a pen pressure detecting unit 27 in addition to the tablet 14. The output device includes a display driver 25 in addition to the liquid crystal display device 13.
In addition, the electronic organizer 11 has a communication control unit 26 for performing communication with an external terminal, a ROM 23 storing a control program, and a RAM 2 serving as a temporary storage device for internal data.
4 are provided, and have a CPU 20 for controlling them.

The tablet 14 is disposed so as to overlap the display screen of the liquid crystal panel 13, and has a transparent touch area corresponding to the display input area 12a of the touch panel 12. When the tablet 14 is touched (pressed) with a touch pen or the like as data input means to the tablet 14,
The coordinate position on the touched tablet 14 is detected by the coordinate detecting unit 22 and is converted into digital plane coordinate data. At the same time, the pen pressure of the touch is also detected by the pen pressure detecting section 27 and is converted into digital pen pressure data.

The CPU 20 executes a control program stored in the ROM 23 in accordance with a touch input operation signal input from the tablet 14 via the tablet controller 21. Here, the touch input operation signal is an input signal detected by the tablet 14 by an operation of a touch pen or the like. The programs stored in the ROM 23 include a handwriting input processing program for displaying handwriting, and a program corresponding to various operation modes such as converting handwritten data into output data. In addition, font patterns (fixed data such as a character recognition dictionary) of characters, numbers, symbols, and characters to be displayed on the liquid crystal display device 13 are also stored.

Next, the operation of detecting coordinate data and pen pressure data will be described. First, when the tablet 14 is pressed with the touch pen, an electric action (change in voltage) is generated at that position in the tablet 14. The coordinates of the position where the voltage has changed are set as coordinate data (X, Y), and the amount of change in the voltage is set as pen pressure data. The detected voltage change is converted into 256-step digital data of 0 to 255 according to the change.

FIG. 3 is a diagram showing the concept of coordinates on the tablet 14. In the figure, coordinates such as (Xm, Ym) are set at the origin (0, 0) at the upper left corner of the input area 12a of the touch panel 12.
0). Input area 1 of touch panel 12
The trajectory of the handwritten data input by touching 2a with a touch pen or the like is sampled as the coordinate position (X, Y) of each pixel of the trajectory. Each of the sampled coordinates (X1, Y1), (X2, Y2),.
., (Xn, Yn) are sequentially drawn to display the trajectory of the handwritten data.

Next, the control in the case where the pressing force (pen pressure) and the input speed (moving speed) are used as the operation characteristics will be described. Below, based on the coordinate data and pen pressure data,
That is, the operation of converting the input data when the pressing force is set as the operation characteristic will be described with reference to the flowchart of FIG. First, the operator touches the touch panel 1 with a touch pen.
A character or a figure is drawn on the line 2 with an arbitrary locus (S1). Then, a pressing force (pen pressure) corresponding to each pixel (or a pixel at a predetermined interval) in the drawn locus is detected (S2).
Then, an average value of the pressing force is calculated from the pressing forces corresponding to all the pixels in the trajectory (S3). For example, the digital value D1 of the pressing force of the pixel 1 is 150, the digital value D2 of the pressing force of the pixel 2 is 120, and the digital value D3 of the pressing force of the pixel 3 is 15
7. When the digital value Dm of the pressing force of the pixel m is 139, the average value Davr of the pressing force is obtained by the following equation. Davr = (D1 + D2 + D3 +... + Dm) /
m

Next, the average value Davr of the pressing force is set to a predetermined value (for example, a digital value: 12 which is an intermediate point between 0 and 255).
8) It is determined whether or not it is above (S4). When the average value Davr of the pressing force is equal to or more than a predetermined value (S4: YE
S), since the input (trajectory) of the operator means that the input is strong and confident, the input is directly used as input information without conversion (S5). On the other hand, when the average value Davr of the pressing force is not equal to or larger than the predetermined value (S4: N
O), meaning that there is no confidence in the input by the operator, the input conversion processing is performed to obtain input information (S)
6). The input information is determined based on the input information in S5 or S6 (S7), and the process ends.

FIG. 5 is a conceptual diagram in the case where the locus of handwritten data is converted by pen pressure. The left diagram is a locus (line) drawn on the touch panel 12 by the operator with the touch pen. When the operator draws a line with certainty with certainty, the average value Davr of the pressing force is equal to or greater than a predetermined value, and the line as it is becomes the input information (upper right figure). On the other hand, when the operator draws the line weakly without confidence, the average value of the pressing force Davr
Is smaller than a predetermined value, the line is converted into a straight line as one of the standard figures (lower right figure).

In FIG. 5, the trajectory is converted to a straight line. However, the thickness of the trajectory line may be reduced. FIG.
It is a conceptual diagram in case the thickness of the locus | trajectory of handwritten data is converted by pen pressure. If the operator draws the line with confidence, the average value Davr of the pressing force is equal to or greater than a predetermined value, and the line as it is becomes the input information (upper right figure). on the other hand,
If the operator draws a weak line without confidence, the average value Davr of the pressing force is less than a predetermined value, and the point of the line is converted to a smaller value (lower right figure).

FIG. 5 shows the case where the trajectory is converted into a straight line which is one of the standard figures. However, depending on the shape of the trajectory, other standard figures such as circles, ellipses, arcs, parallelograms, etc. may be used. May be converted to FIG. 7 is a conceptual diagram in the case of converting a figure of handwritten data by pen pressure. When the line is drawn strongly, the average value Davr of the pressing force is equal to or more than a predetermined value, and the graphic as it is becomes the input information (upper right figure). On the other hand, when the pressing force is weak, the average value of the pressing force D
Since avr is equal to or less than a predetermined value, pattern matching processing is performed and converted as data representing a recognized figure (lower right figure).

If the input trajectory is a character, a function for converting the character into the character code can be provided. In such a data input device, it may be determined whether or not to perform conversion in accordance with the pressing force, and if it is determined that the conversion is to be performed, the data may be converted to a character code. In this case, for example, when the pressing force is weak, the input locus can be converted into a character code. In addition, the editing mode may be switched, the color of the character, the character font, etc. may be converted.

When the apparatus has a function of recognizing input information as characters and outputting the input characters as voice,
It is also possible to determine whether or not to output a sound according to the pressing force, and to output the sound when it is determined that the sound is to be output. In this case, for example, when the pressing force is weak, the input trajectory can be language-converted and output as voice. In addition, the volume of the output sound may be changed, or the timbre may be converted.

Next, an operation of converting input data based on handwriting information obtained from input information, that is, when input speed is set as an operation characteristic, will be described with reference to a flowchart of FIG. First, the operator draws a character or a figure on the touch panel 12 with an arbitrary locus using a touch pen (S
11). Next, the pressing timing of each pixel corresponding to the position of the drawn locus is detected (S12). Then, the input speeds of all the trajectories are detected from the detection results of the pixels having continuous trajectories (S13). Specifically, pixel 1, pixel 2, pixel 3,
By detecting the pressing timing of each successive pixel corresponding to the trajectory information, such as pixel m, the input speed of the entire trajectory can be detected.

Next, it is determined whether or not the input speed is equal to or higher than a predetermined value (S14). If the input speed is equal to or higher than the predetermined value (S14: YES), it means that the input (trajectory) of the operator is input quickly and confidently, and the input is input information without conversion. (S15).
On the other hand, if the input speed is not higher than the predetermined value (S14: N
O), which means that the operator does not have confidence in the input, so that the input is converted and used as input information (S1).
6). The input information is determined based on the input information in S15 or S16 (S17), and the process ends.

FIG. 9 is a conceptual diagram in the case where the trajectory of the handwritten data is converted by the handwriting speed. The left figure is the locus (line) drawn on the touch panel 12 by the operator with the touch pen
It is. If the operator draws the line quickly with certainty, the input speed becomes equal to or higher than the predetermined value, and the line as it is becomes the input information (upper right figure). On the other hand, if the operator draws a line slowly without confidence, the input speed is lower than a predetermined value, and the line is converted into a straight line (lower right figure).

FIG. 10 is a conceptual diagram in the case where the thickness of the trajectory of the handwritten data is converted by the handwriting speed. When the operator draws a line quickly, the line is used as input information (upper right figure). On the other hand, when the operator draws a line slowly, the point of the line is converted to a smaller value (lower right figure).

FIG. 11 is a conceptual diagram in a case where a figure of handwritten data is converted by a handwriting speed. When the operator draws a line quickly, the figure as it is becomes the input information (upper right figure). On the other hand, when the operator draws slowly, a pattern matching process is performed and converted as data representing the recognized figure (lower right figure).
