Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an information processing device equipped with coordinate input means such as a touch panel.

[Prior Art] Some coordinate input devices are equipped with a switch, such as a mouse, and are capable of capturing not only coordinate data for specifying a coordinate position (but also a signal indicating whether the switch is pressed or not). When such a device is used as a coordinate manual means for an information processing device, it is possible to add and input the switch signal input from the switch in addition to the coordinate data. In addition to specifying the coordinate position, it is also possible to give meaning to the specified position.

On the other hand, there are coordinate input devices such as tablets and lightbens that can simply input coordinate data manually, and when these are used, the input coordinate data simply means an address, for example, an address on a display screen. Ta.

[Problem to be Solved by the Invention] For this reason, conventionally, in an information processing device that requires processing that requires input of data other than coordinate data from a coordinate input device, It was not possible to use a coordinate input device.

The present invention has been made in view of the above problem, and even in an information processing apparatus using a coordinate input device that can input only coordinate data, data input that gives a predetermined meaning to the coordinate data, such as a switch signal, can be performed. An object of the present invention is to provide an information processing device that can perform various inputs.

[Means and operations for solving the problems] In order to solve the above problems, an information processing apparatus according to the present invention is configured as follows.

An information processing device for processing coordinate data, comprising an input means for inputting coordinate data by specifying a coordinate position, a measuring means for measuring a time continuously indicated by the input means, and a measuring means for measuring by the measuring means. and an addition means for adding predetermined functional information to the coordinate data input by the input means in accordance with the time at which the coordinate data is input.

With the above configuration, when coordinate data is input, it is possible to perform a function corresponding to the length of time the coordinate position continues to be specified.

[Example] Hereinafter, a case where a touch panel is used as an example of the present invention will be described with reference to the accompanying drawings.

In this embodiment, a two-button (left and right) mouse is emulated using a touch panel. This means that if the touch panel is pressed continuously, the amount of time the touch panel remains pressed is measured, and that time corresponds to which of the two mouse buttons was pressed.

FIG. 1 is a block diagram showing an information processing apparatus that emulates a mouse using a touch panel, which is an embodiment of the present invention.

In the figure, 1 is a CPU that controls the entire touch panel device;
2 is shown in the flowcharts of FIGS. 3 and 4, C
ROM stores a control program executed by the PUI, 3 is a RAM that stores data, 4 is a CPU
This timer 4 is used to interrupt the touch panel at regular intervals, and measures the amount of time the touch panel is pressed. 5 is a display device such as a CRT, and 6 is a touch panel for inputting coordinate data.

In addition, there is a part in the RAMB that stores some characteristic information. 31 is color information, which stores the display color of the cursor that displays the coordinate position specified on the touch panel 6 on the display unit 5. .32 is coordinate information for storing the address of the cursor displayed on the display unit 5, and 33 is a touch time for storing the time for which the touch panel 6 is kept pressed.

34 is called a touch flag, and is a flag for storing the state of whether or not the touch panel 6 is pressed.

If this value is "O", it means "not pressed", and if this value is "1", it means "pressed". 35 is touch panel 6
This is function information indicating the function to be performed depending on the time that the key is pressed. Functional information has the same meaning as information about which button is pressed when a mouse with buttons is operated. Reference numeral 36 denotes an area fixedly reserved on the RAM in order to pass the coordinate information and function information obtained in the timer interrupt processing shown in FIG. 2 to other processes.
It is called an area.

FIG. 2 is a flowchart showing the processing of interrupts from timer 4 in this embodiment. First, an interrupt request is generated from the timer 4, and the CPU 1 starts interrupt processing.

In step S1, first, touch information indicating whether the touch panel 6 is being pressed and coordinate data indicating which position on the touch panel 6 is being pressed are obtained, and this coordinate data is set in the coordinate information 32. If the touch panel 6 is not pressed, the coordinate information 32 is left as is.

Next, a cursor is displayed on the display section 5 according to this coordinate information 32 and color information 31. The color of the cursor indicates the function corresponding to each of the two buttons on a mouse.

As long as it corresponds to the function, it does not have to be a color (for example, the shape of the cursor may be changed to visualize the correspondence with the function. In this embodiment, the initial value of the color information 31 is 2. It may be a value indicating an appropriate color among the colors, and the coordinate information 3
The initial value of 2 may be any value as long as it is within the range that can be displayed on the display unit 5, such as a corner of the display screen.

In step S2, it is checked whether or not the touch panel 6 is pressed based on the touch information obtained in step 1. If it is pressed, the process advances to step S3, and if it is not pressed, the process advances to step S9.

In step S3, the touch panel is pressed, so in order to measure the pressed time, a touch time 33
Add 1 to . In other words, the touch time is recognized as the number of consecutive times it is determined that the object has been touched during the timer interrupt processing. That is, (timer interrupt interval) x (value of touch time 33) is the pressed time.

In step S4, the touch time 33 is referred to.

If the touch time 33 has reached an appropriately determined value, that is, if a certain period of time (for example, 1 second) has elapsed, step S
Perform the process in step 5. If it has not yet passed, step S5 is skipped and the process proceeds to step S6.

In step S5, the value of the color information 31 is changed so that the value up to that point is "
If it is "red", it is written as "white", and if it is "white-", it is written as "red", and so on. Once the color information 31 has been rewritten, the cursor is displayed again in order to immediately reflect it in the color of the cursor. Also, in order to alternately change the color of the cursor at regular intervals, the touch time 33 is cleared and set to "0".

In step S6, the value of the touch flag 34 is set to "1". That is, it is set to "pressed".

In step S7, the value of the function information 35 is cleared. This is because the value of the function information 35 is set depending on the time the touch panel is pressed, and the value of the function information 35 is not determined while the touch panel 6 is being pressed.

In step S8, the values of the coordinate information 32 and the function information 35 are copied to the fixed RAM area 36 in order to pass them from the interrupt processing to other processes.

On the other hand, if it is determined in step S2 that the touch panel 6 is not pressed, the process of step S9 is performed.

In step S9, the value of the touch flag 34 is determined, and if the value is "0" (not pressed), step S7
Branch into. This branch occurs when the touch panel 6 is not pressed at the moment and was not pressed during the previous timer interrupt processing. After the 0 branch, the function information 35 is cleared in step S7 as already mentioned. Then, in step S8, function information 35 and coordinate information 32 are set in the fixed RAM area.

If the touch flag 34 is “1”, the next step S
IO is performed. This case is a case where the touch panel 6 is not currently pressed, but it was determined that it was pressed in the immediately preceding timer interrupt process, and corresponds to when the time period during which the touch panel 6 has been pressed has been determined.

In step S10, first, the touch flag 34 is set to "0" (
(not pressed) is set. Also, touch time 3
Clear the value of 3 and return it to "0". Since the time that the touch panel 6 was pressed has been determined, the function information 35
You can also determine the value of The functional information 35 is determined according to the value of the color information 31 at the time when the time that the touch panel 6 has been pressed is determined. For example, color information 31
If the value of is “red”, the value of function information 35 is “function 1”
, if the color information 31 is "white", the value of the function information 35 is "
Function 2” is given.

Thereafter, the process branches to step S8, and in step S8, the coordinate information 32 and function information 35 are set in the fixed RAM area 36 in order to pass them to a process that requires them, such as an application process.

This completes the timer interrupt processing. Based on the functional information and coordinate information obtained through this process, emulation of the specific functions of the two-button mouse is performed.

If the data set up in the fixed RAM area 36 by the timer interrupt processing is passed to an application process, for example, a two-button mouse can be emulated by the procedure described in the flowchart of FIG.

First, in step 31, if the functional information received by the application in the fixed RAM area 36 is cleared, it is assumed that no operation other than specifying coordinates has been performed, and no further processing is performed on the data obtained from the touch panel. do not have.

If the function information in the fixed RAM area 36 contains some value, the value is further determined in step S3.
Judgment is based on 2.

In step S32, if the function information in the fixed RAM area 36 is "Function 1", that is, if you take your finger off the touch panel when the cursor is white, the command will simply indicate the address of the cursor on the display screen. Suppose it is a meaning. This is done by pressing somewhere on the touch surface of the touch panel,
This means that if you release your finger while the white cursor is displayed, the cursor will simply move to that position.

If the function information in the fixed RAM area 36 is "Function 2", that is, if you release your finger from the touch panel when the cursor is red, it means that the image specified on the screen, for example, an icon, is designated as the object of movement. shall have it. The image targeted for movement is moved to the position of the cursor address specified immediately after. That is, for example, an icon pointed to by a red cursor moves to the next position pointed to by a white cursor.

As described above, even in a system using a touch panel, operations can be performed as if using a mouse. This is not just two functions as in the example;
It is possible to have three or more.

Further, the present invention is not limited to a touch panel, and even an information processing device using a coordinate input device such as a penlight or a digitizer can perform the same operations as the touch panel described in the embodiment.

Note that FIG. 4 is a flowchart of timer interrupt processing for the mouse.

Since a mouse allows input from a switch in addition to coordinate data, it is sufficient to perform a function corresponding to the input value of the switch. Therefore, extra steps such as measuring input time are unnecessary.

In step S31, coordinate data is read and input signals from the switches are read, and a cursor is displayed based on the value of the coordinate data.

In step S32, the read data is written into a predetermined memory area (memory area corresponding to the fixed RAM area in FIG. 2). This memory area is also used to pass functional information and coordinate information in the same way as explained in FIG. 2. If the right button is pressed, "Function 1" is set as the function information in the memory area, and if the left button is pressed, "Function 2" is set as the function information in the memory area. If the button is not pressed, it is cleared.

The functional information and coordinate information obtained through the above procedure can be processed as they are by the application process shown in FIG. 4. That is, it is possible to obtain data having the same meaning when using the mouse as described above and when using the touch panel described in the embodiment.

[Effects of the Invention] As explained above, by measuring and utilizing the pressing time of the touch panel, even if the information processing device uses a coordinate input device that can only input coordinate data, coordinates can be input while specifying an address. This has the effect of being able to handle data input without data, such as processing that requests input from a switch.
