Abstract

PURPOSE:To impart specific meaning to coordinate data by selecting a choice which is displayed even when the information processor uses a coordinate input device where only coordinate data can be inputted. CONSTITUTION:When function information in a fixed RAM area 35 has any value, it is decided what the value is. When a function 1 is decided, it is meant to be the instruction of the address of the cursor on a display screen and when a choice 1 is selected, the cursor is moved to the position of a touch panel 6 which is pressed right before a menu is displayed. When a function 2 is decided, an image instructed on the screen is moved to the position of the cursor address instructed right after the specification. When a function 3 is decided, an image instructed on the screen, i.e., an image specified as an object to be copied is copied to the position of the cursor address instructed right after the specification. Thus, a system which uses a touch panel can be operated as if a mouse were used.

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 can simultaneously capture not only coordinate data for specifying a coordinate position, but also a signal indicating whether or not the switch is pressed. There are things you can do. When such a device is used as a coordinate input means of an information processing device, the coordinate position is simply specified by the switch signal input from the switch in addition to the coordinate data indicating the coordinate position specified by the coordinate input means. In addition, it is possible to give meaning to the position specification.

On the other hand, there are coordinate input devices such as tablets and lightbens that can simply input coordinate data, 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 device using a coordinate input device that can input only coordinate data, by selecting a displayed option, a predetermined meaning can be assigned to the coordinate data. The purpose of the present invention is to provide an information processing device that can be used as an information processing device.

[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 that processes coordinate data, comprising an input means for specifying a coordinate position and inputting the coordinate data, and a menu for displaying one or more options as a menu in response to input of the coordinate data by the input means. a display means; a timer for timing the time during which the coordinate position is designated by the input means; and a clock means for executing the designated choice when the choice displayed by the menu display means is designated by the input means. and control means for controlling.

With the above configuration, when coordinate data is input, a function selected from a menu displayed according to the length of time the coordinate position continues to be specified is performed.

[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 three-button (left, middle, and right button) mouse is emulated using a touch panel.

This means that if the touch panel is pressed continuously for 1 second, a pop-up menu with three options will be displayed.
Have them choose one of the three options.

Then, which one is selected corresponds to the functions assigned to the three switches on the mouse.

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 the control program executed by PU1, 3 is RAM for storing data, 4 is CPU
This is a timer for interrupting at regular intervals. Reference numeral 5 represents a display unit such as a CRT, and reference numeral 6 represents a touch panel that outputs the designated coordinate data to the CPU 1 when a coordinate point is designated, for example, with a finger.

In addition, there is a part in the RAMB that stores some characteristic information. 31 is coordinate information for storing the address of the cursor displayed on the display unit 5, and 32 is the time period during which the touch panel 6 is pressed. is the touch time to remember.

33 is a menu flag indicating that the pop-up menu is being displayed; if it is "1", the menu is being displayed;
"O" indicates that the menu is not being displayed. Function information 34 indicates a function to be performed depending on the time the touch panel 6 has been pressed. This function information is information that specifies the function associated with the coordinate instruction, similar to information about which button is pressed when a button-equipped mouse is operated, for example. Reference numeral 35 denotes an area fixedly reserved on the RAM 3 in order to pass the value of the coordinate information 31 and the value of the function information 34 obtained in the timer interrupt processing shown in FIG. 2 to other processes, and is referred to as a fixed RAM area. ing.

FIG. 2 is a flowchart showing the processing of CPU i, which shows the processing of interrupts from timer 4 in this embodiment.

First, an interrupt request from timer 4 occurs, and CPLII
interrupt processing is started.

In step S1, a determination is made as to whether or not the touch panel 6 is being pressed. If it is not pressed, there is no information to be obtained, so the touch time 32 is cleared in step SIO, and the interrupt processing ends. touch time 32
indicates the time that the touch panel 6 continues to be pressed, so if the touch panel 6 is not pressed, it is "0".
is set. On the other hand, if the touch panel 6 is pressed, step S2 is performed next.

In step S2, the coordinate position being pressed on the touch panel 6 is set in the coordinate information 31.

In step S3, the value of the menu flag 33 is determined. If the value of the menu flag 33 is "0", that is, if the menu is not being displayed, the process of step S4 is performed.

In step S4, the coordinate information 31 obtained in step S2
The cursor is displayed on the attachment indicated by the value.

In step S5, the time period during which the touch panel 6 continues to be pressed is determined. This is to ensure that the menu is displayed only when the touch panel 6 is pressed continuously for a certain period of time. In this way, if you just want to change the cursor position, for example, you only need to specify the coordinates on the touch panel 6, and there is no need to select from the menu. In this embodiment, the predetermined time is 1 second. Further, the determination is made based on the value of the touch time 32. The touch time 32 is a simple counter, and is incremented by 1 in step S6, which will be described later. That is, in step S5, (value of touch time 32) x (timer interrupt interval time)
is the elapsed time, and the touch time 3 is such that this is 1 second.
With a value of 2, it is determined that 1 second has elapsed.

In step S6, since the pressed time has not yet reached 1 second, 1 is added to the touch time 32. That is,
This means that the timer interrupt interval time has elapsed.

Further, if it is determined in step S5 that one second has elapsed while the touch panel 6 has been pressed, step S7 is performed.

In step S7, a menu is first displayed, and then the menu flag 33 is set to 1. This menu is for selecting functions, and is equivalent to the 9 button on a mouse.
In this embodiment, since the mouse has three buttons, there are also three menu options.

Interrupt processing ends here. Once step S7 has been completed, all that remains is to wait for a menu to be selected.

On the other hand, the value of the menu flag 33 is "1" in step S3.
If it is determined that this is the case, the process of step S8 is performed.

When the menu flag is "1", the expected input is only menu selection, so in step S8, it is determined whether the touch panel 6 is pressed in the menu selection area or in other areas. It is determined whether it is an area. If the pressed button is not in the selection area, the input is ignored and the interrupt process ends. If any of the options displayed on the menu is pressed, the process advances to step S9.

In step S9, the function information 340 is set according to the item selected from the menu.

Since this embodiment emulates a three-button mouse, the displayed menu has three options.For example, these options are called option 1, option 2, and option 3, and each is selected. The values set in the function information 34 when
Each option is selected by pressing a designated area for each option on the touch panel 6.

Further, the function information 34 set in the previous stage of this step and the coordinate information 31 set in step S2 are copied to the fixed RAM area 35, which is an area for passing data to other processes.

This completes the timer interrupt processing. The fixed RA
Based on the value of the function information 34 passed through the M area 35 and the value of the coordinate information 31, emulation of the specific functions of the three-button mouse is performed.

If the data set in the fixed RAM area 35 by the timer interrupt processing is passed to an application process, for example, a three-button mouse can be emulated by the procedure described in the flowchart of FIG.

First, in step S31, if the value of the function information in the fixed RAM area 35 received by the application is cleared, it is assumed that no operation other than specifying coordinates has been performed, and the processing for the data obtained from the touch panel is as follows. I can't get enough of this.

If the function information in the fixed RAM area 35 contains some value, the value is further determined in step S32.
Judge by.

In step S32, if the value of the function information in the fixed RAM area 35 is "function 1", it is assumed that this only means an instruction for the address of the cursor on the display screen. That is, for example, if option 1 is selected, the cursor moves to the position indicated by the value of the coordinate information passed to the application process along with the function information. The position indicated by the value of the coordinate information is the position where the touch panel 6 was pressed immediately before the menu was displayed.

If the value of the function information in the fixed RAM area 35 is "Function 2", it means that the image designated on the screen, such as an icon, is designated as the object to be moved. The image designated to be moved is moved to the position of the cursor address designated immediately after the designation. That is,
For example, if the icon displayed on the display unit 5 is specified by pressing the touch panel 6 and option 2 is selected, the icon is then specified by pressing the touch panel 6 again to specify the moved position, and When option 1 is selected, it is moved to the specified position. Fixed RAM
If the value of the function information in the area 35 is "Function 3", it means that the image designated on the screen, for example, an icon, is designated as a copy target. The image designated to be copied is copied to the position of the cursor address designated immediately after the designation.

That is, for example, if an icon displayed on the display unit 5 is designated by pressing the touch panel 6' and option 3 is selected, that icon is then displayed on the touch panel 6 again.
is pressed to specify the position after copying, and when option 1 is selected, the copy is made to the specified position.

As described above, even in a system using a touch panel, operations can be performed as if using a mouse. This is not just three functions as in the example, but
It may be two, four, or of course more than that.

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

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, the coordinate data is read, the input signal is read by the switch, 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 selected, if the middle button is pressed, "Function 2" is selected, and if the left button is pressed, "Function 3" is selected in the memory area. is set as the function information. 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. 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, even in an information processing device using a coordinate input device that can input only coordinate data, by selecting a displayed option, the coordinate data can be given a predetermined meaning. It has the effect of being able to
