[0010]

Embodiments of the present invention will be specifically described below with reference to the drawings. FIG. 1 is a block diagram showing a configuration of an information input / display apparatus implementing a stamp graphic display method according to the present invention. The information input / display device includes a touch panel display 1 and a control device 2 using a personal computer. The control device 2 includes a coordinate input unit 3, a touch panel control unit 4, and an image memory 5.

The touch panel display 1 has a transparent touch panel overlaid on a display screen, and the touch panel optically determines a position touched by a finger or the like to the resolution of the display (the number of pixels in the X-axis direction: 1024, the number of pixels in the Y-axis direction: 768, etc.), and the coordinate data is transmitted to the coordinate input unit 3 of the control device 2 by detecting the x and y coordinate values on the display. An image developed in the image memory 5 of the control device 2 is displayed and output on a display integrated with the touch panel.

The coordinate input unit 3 of the control device 2 has an RS232
The coordinate data is received from the touch panel of the touch panel display 1 using a communication interface such as C or USB.

The touch panel control unit 4 extracts coordinate data from the coordinate input unit 3 and determines the thickness and color (thickness and color are determined by the control unit) based on the previous coordinates, the newly extracted coordinates, and the extracted coordinates. Can be changed by the user I / F possessed by the user), or the stamp graphic data stored in the storage device is pasted on the image memory at the touched location. R on the image memory
The GB image data is developed and output and displayed on the display by the video output means. The “stamp graphic” refers to an image that has a meaning in a direction registered in advance in order to be displayed for attention or emphasis in a presentation or the like.

Next, the input operation and the display of the stamp figure on the display screen of the touch panel display will be described with reference to FIG. FIGS. 2 to 4 show a display screen 1a of the touch panel display 1. As shown in FIG. 2, when the stamp button 11 is touched while a toolbar capable of selecting the stamp button 11 and the edit button 12 is displayed. , A stamp list is displayed as shown in FIG. In this example, three types of stamp figures can be selected. The stamp figure displayed at this time has a rotation angle of 0 °
It is a stamp figure displayed at the time of.

Then, for example, as shown in FIG. 4, after selecting an arrow stamp figure, when touching an arbitrary position on the display screen 1a with a finger or the like, the coordinates (starting coordinates) of the position are read, and When the stamp figure is dragged and detached (released) in the direction in which the stamp figure is turned, the coordinates (end coordinates) of that position are read and sent to the coordinate input unit 3 of the control device 2 shown in FIG. As a result, the start coordinate and the end coordinate are put on the connecting line, and the arrow stamp figure 14 is displayed.
Is displayed with the tip as the end coordinate position.

Here, the calculation of the stamp figure rotation angle will be described with reference to FIG. Start coordinates (x
From the (1, y1) and end coordinates (x2, y2), a change amount Δx (x2−x1) in the X coordinate direction and a change amount Δy in the Y coordinate direction
(Y2-y1) is obtained, and the stamp figure rotation angle?
= ΔY / ΔX.

[0017]

[Table 1]

Table 1 shows an example in which the stamp figure rotation angles are obtained at intervals of 10 ° from the Y-axis direction. This angle interval is arbitrarily determined. The rotation angle of the stamp figure uses an approximate value of the calculation result. For example, -ΔY,
In the case of −ΔX and ΔY / ΔX = 0.900, the tamped figure rotation angle θ is “0.0.0” where ΔY and ΔX are both negative in Table 1 and the value of ΔY / ΔX is closest to “0.900”. 839 ”, which is“ 230 ° ”.

The stamp figure is rotated clockwise from the Y-axis by the figure rotation angle calculated in this way, and is drawn so that the end coordinate is at the tip of the stamp figure. Also,
If the stamp figure has text, figure rotation angle (θ °)
As shown in Table 2, horizontal writing characters and vertical writing characters are selectively used, and the characters are rotated by the character rotation angle and drawn over the stamp figure. FIG. 6 shows a stamp 15 with characters.
Shows the relationship between the display example of the above and the stamp figure rotation angle.

[0020]

[Table 2]

For example, if the stamp figure rotation angle is 45 °
When the angle is 89 °, the character is written vertically and the character is (90-θ)
Rotate counterclockwise by °. In order to erase the stamp figure, the user touches the display screen with a finger or the like, then drags the stamp figure in a direction opposite to the direction in which the stamp figure was pasted, and performs a detach operation.

For example, as shown in FIG. 7A, the finger touched is drawn from left to right and detached, and after the stamp graphic 14 shown in FIG. As shown, touch the tip of the arrow of the stamp figure 14,
When the finger is drawn from left to right, the stamp figure 14 is erased as shown in FIG. Or,
When the one-touch erase mode is selected, the stamp figure is erased only by touching the displayed stamp figure.

The processing according to the present invention described above by the control device 2 of the information input / display apparatus shown in FIG. 1 is performed as shown in the flowchart of FIG. When this process is started, the process waits for the touch panel on the display screen to be touched, and when touched, stores the start coordinates. After that, it waits for detachment, and when detached, saves the end coordinates. Then, the stamp figure rotation angle is calculated from these coordinate values, and the drag length is calculated by the equation.

Next, when the drag length is L (for example, 1c
(the length corresponding to m) is determined. If not, the process returns to the first touch check. If it has exceeded, then it is determined whether or not the start coordinate is on the stamp. If it is not on the stamp, the stamp figure is rotated by the previously calculated rotation angle, the end coordinates are attached to the tip, and the rotation angle and the stamp coordinates are stored.

Next, it is determined whether or not the stamp is a character stamp. If the stamp is not a character stamp, the process returns to the beginning. If the stamp is a character stamp, the range of the rotation angle of the stub figure in Table 2 is checked. Select vertical or horizontal writing. Then, the character rotation angle is calculated, the character rotation direction is selected, the character is drawn, the character is rotated and attached to the stamp figure, and the process returns to the beginning.

It is determined whether or not the preceding start coordinate is on the stamp. If the start coordinate is on the stamp, the stamp figure is erased if the one-touch erase mode is set, and the process returns to the beginning. Judge whether or not
If so, delete the stamp figure and return to the beginning, otherwise return to the beginning.

[0027]

As described above, according to the present invention, a stamp figure can be easily rotated and pasted in an arbitrary direction in an information input / display apparatus. There is no need to bother to select a figure, and it is also possible to eliminate the waste of storing stamp figure data having different angles for each required angle.

In addition, the character of the stamp figure with the character is selected to be horizontally written or vertically written according to the direction of rotation, and is drawn by rotating it at an angle within 45 °. It is possible to eliminate the difficulty of reading characters by being displayed vertically.

Furthermore, since the pasting and erasing of the stamp figure can be performed without switching the mode, the usability is greatly improved in the operation of repeating the pasting and erasing of the stamp figure. Alternatively, it is also possible to delete the stamp figure just by touching it.
