2. Description of the Related Art Conventionally, a device for inputting various instructions using a human finger or the like using a touch panel or the like is generally used to select information mainly by pointing some one of coordinate positions. Met. One selection operation is completed by pressing and releasing the item to be selected with a finger.

The touch panel itself is 1
It has already been proposed that not only a point can be detected but also a plurality of touch positions can be detected at the same time systematically.
In addition, a touch panel that can detect the vertical and horizontal directions of the screen and also the vertical direction of the screen, that is, the strength of the pressure applied by the touch is already in practical use.

[0004]

However, in the conventional touch panel described above, although a touch input device capable of simultaneously detecting a plurality of touches can be realized,
When a plurality of points are touched, the center of the circle connecting the coordinates of touching the plurality of points is interpreted as the touch position, so in reality, it is the same as the operation of touching with one point. Therefore, when drawing a figure that connects multiple points,
In the end, the touch input had to be performed several times, which was troublesome for the work.

The present invention has been made in view of the above problems, and in a figure forming apparatus for drawing a figure by touch input, when drawing a figure connecting a plurality of points, touch input of a plurality of points is performed at the same time. An object of the present invention is to provide a figure forming device and method for drawing a figure by performing detection without performing touch input in plural times.

[0006]

The input device according to the present invention for achieving the above object has the following configuration. That is, in a figure forming device that draws a figure by touch input, when a plurality of touch positions are detected at the same time by a detection unit that detects a touch position with respect to a coordinate detection surface, and a plurality of touch positions are detected by the detection unit. An acquisition unit that acquires each of the images and a determination unit that determines a figure to be drawn based on the plurality of touch positions acquired by the acquisition unit are provided.

A figure forming method according to the present invention for achieving the above object has the following configuration. That is, it is a figure forming method of drawing a figure by touch input, and a step of detecting a touch position with respect to the coordinate detecting means, and when a plurality of touch positions are simultaneously detected by the detecting means, each of the plurality of touch positions is detected. And a step of determining a figure to be drawn based on the plurality of touch positions acquired by the acquisition means.

[0008]

With the above configuration, when there are a plurality of touch inputs on the coordinate detection surface at the same time, the touch positions of the plurality of touch inputs are acquired, and drawing should be performed based on the acquired touch positions. The figure is determined.

Here, when the finger is released from the touch input unit 3, a linear figure is determined by the two points touched at that time.

FIG. 3 is a flowchart showing the control flow of the touch input device according to the first embodiment. The control flow relating to this embodiment will be described with reference to the flowcharts of FIGS. First, in step S101, the touch detection of the touch input unit 3 waits for two points to be touched. When two touches are detected (YES in step S101),
The process moves to step S102. In step S102,
Obtain two touch coordinate positions. Next, step S1
In 03, a figure connecting the two points based on the acquired two coordinates, in this case, if a straight line is selected as the mode of the figure in advance, a straight line connecting the two points is drawn on the display unit as the figure. It In step S104, it is checked whether or not the touch is released. If the touch is released, the control is moved to step S106, and if the touch is not released, the control is moved to step S105.

If the touch is not released, it is checked in step S105 whether or not the touch position has moved. If the touch position has moved, the process returns to step S102 to execute the drawing process again. On the other hand, if the movement of the touch position is not detected, the process returns to step S104 again to check whether or not the touch position has been released. Step S104
When it is detected that the touch is released, the current drawing information is stored and stored in step S106, and the process is terminated.

As described above, according to the first embodiment, it is possible to instruct a plurality of points at the same time to draw a figure, and the efficiency of the figure drawing operation is improved. <Second Embodiment> In the first embodiment, graphic drawing is performed in a preset graphic mode. In the second embodiment, it is possible to switch the graphic mode by touch pressure when drawing the graphic.

As a result, the figure connecting two points at the touch position is displayed from a straight line to a rectangle. If the finger is released here, a rectangular figure is determined.

FIG. 5 is a flowchart showing the control flow of the touch input device of the second embodiment. The flow of control relating to this embodiment will be described with reference to the flowcharts of FIGS. First, in step S201, it waits for two points to be touched by the touch detection of the touch input unit. Two

Next, in step S203, based on the acquired two coordinates, a figure connecting the two points, in this case, if a straight line is selected as the mode of the figure in advance (first), a straight line connecting the two points is obtained. It is drawn on the display. In step S204, it is checked whether or not the touch is released, and if the touch is released (YES in step S204).
S) If the touch is not released to step S208 (NO in step S204), the control is moved to step S205.

If the touch has not been released, it is checked in step S205 whether or not the touch position has moved. If the touch position has moved (YES in step S205), the process returns to step S202 to execute the redrawing process. However, if the movement of the touch position is not detected (NO in step S205), the control proceeds to step S206. In step S206, it is checked whether or not the touch pressure has changed, and if there is no change in pressure (step S20).
(NO in step 6), the process returns to step S204 again to inspect whether or not it has been released. If there is a change in pressure (step S
(YES in 206) The control is moved to step S207.

A step S207 changes the mode of the graphic. In this example, the mode is changed from a straight line to a rectangle. Therefore, returning to step S203, a rectangle is drawn instead of a straight line. When it is detected in step S204 that the touch is released, the current drawing information, that is, a rectangular figure in this embodiment is stored and stored in step S208, and the process ends.

As described above, according to the second embodiment, it is possible to draw a figure by designating a plurality of points at the same time, and to change the figure to be drawn by touch pressure (change the drawing mode). And the operability is improved. <Third Embodiment> FIG. 6 is a diagram showing an operation example of the third embodiment.

Reference numeral 61 denotes that two points on the touch input device are touched and a straight line connecting the two points is displayed on the display section. Reference numeral 62 indicates a state where the original straight line is displayed even if the thumb is released. The coordinates of the thumb released here are fixed. Reference numeral 63 indicates that the touched index finger is displaced to draw a straight line from the coordinates touched by the thumb to the coordinates indicated by the index finger touched. If the finger is released here, the figure at that time (a straight line in this case) is determined.

FIG. 7 is a flow chart showing the control flow of the touch input device of the third embodiment. The control flow of this embodiment will be described with reference to the flowcharts of FIGS. 6 and 7. First, in step S301, it waits until two points are touched by the touch detection of the touch input unit. Two

Based on the acquired two coordinates, a figure connecting the two points, in this case, if a straight line is selected as the mode of the figure in advance, a straight line connecting the two points is drawn on the display unit. Step S
In 304, it is checked whether or not the touch is released, and if the touch is released in either one of them (YES in step S304), the control is transferred to step S306, and if the touch is not released (step S304). (NO in S304), the control is moved to step S305.

If the touch has not been released, it is checked in step S305 whether the touch position has moved. If the touch position has moved (YES in step S305), the process returns to step S302 to execute the redrawing process. However, if the movement of the touch position is not detected (step S

Move to 09.

In step S309, it is checked whether or not the remaining one touch position has moved, and if it has moved (YES in step S309), step S309.
A graphic (a straight line in this case) based on the coordinates moved in 310 is redrawn, and the process returns to step S308. If it has not moved (NO in step S309), step S3
Return to 08.

When both touches of the two points are released, in step S311, the information of the figure (in this case, a straight line) which is the current drawing information is stored and stored, and the process is ended. As described above, according to the third embodiment, when two points are simultaneously touch-input to draw a figure, the positions can be determined one by one. Therefore, it is possible to easily perform graphic drawing of a size in which it is difficult to determine two points at the same time.

As described above, according to each of the above-described embodiments, when a figure connecting a plurality of points is drawn, the coordinates of the plurality of points can be detected at the same time, so that the coordinates of the plurality of points can be divided into a plurality of times and displayed on the screen. You can draw a figure without inputting into. Further, in the above embodiment, the case where the mode of the figure is the straight line and the rectangle has been described, but the mode can be easily applied to various figures such as a circle and an ellipse. Further, it is possible to change not only the type of figure but also the type of figure modification, for example, drawing with a solid line or a dotted line.

Further, in the above-described embodiment, in the method of changing the mode (type, modification) of the figure, a method of determining in advance (Example 1) and a case of changing each time the pressing pressure is changed (Example 2) However, when there is no change in the position such as coordinates by a timer,
A method of automatically changing the mode is also conceivable. Also,
In the method of changing the mode by pressing pressure according to the second embodiment, a processing method such as changing the type of figure or changing the modified state by, for example, a single click and a double click, depending on the difference in pressure change within a unit time. Can also be considered.

Further, although the simultaneous touch input of two points has been described in each of the above embodiments, the positions of simultaneous touch input may be three or more points. For example, if 3 points are input simultaneously, a triangle
You can determine a circle passing through the points. The present invention may be applied to a system including a plurality of devices or an apparatus including a single device. Further, it goes without saying that the present invention can be applied to the case where it is achieved by supplying a program to a system or an apparatus.

[0028]

As is apparent from the above description, according to the present invention, when drawing a figure or the like connecting a plurality of points, the touch input of a plurality of points is detected at the same time so that the touch input can be divided into a plurality of times.
