JPS6326719A - Multi-input system consisting of keyboard and pointer device - Google Patents

Abstract

PURPOSE:To ensure the simultaneous inputs through a keyboard and a pointer device by using a mail box as a common data storing area secured between a keyboard input task and a pointer device input task. CONSTITUTION:When an input key routine 10 is started, a keyboard input task II-A and a mouse input task II-B are produced in a task generating process I and work in parallel with each other in a multi-task form. If a keyboard is started, a key code is put into a mail box 33 as long as a key input exists. While an index is obtained to show a specific number of an icon where a pointer is set as long as a mouse button is pushed in case a mouse is started. Then said index is converted into a key code and put into the box 33. In a key code setting process III the key code is extracted out of the box 33 and set to a designated address.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a multi-input method using a keyboard and a pointer device, and in particular to a keyboard that can perform input from a keyboard and input from a pointer device in parallel. and a pointer device.

[Conventional technology]

Conventionally, the input method for information processing devices that can use both keyboard input and a pointer device such as a mouse is that a program selectively selects either the keyboard input mode or the pointer device input mode. It was possible to input data from either the device or the pointer device. That is, the pointer device cannot be used when inputting from a keyboard, the keyboard cannot be used when inputting from a pointer device, and the keyboard and pointer device cannot be used at the same time.

[Problem that the invention seeks to solve]

In the input method of the conventional information processing device described above, only one of the keyboard input mode and the pointer device input mode could be selected, so inputting numbers in the pointer device input mode became troublesome, and the pointer device input mode in the keyboard input mode. The disadvantage is that a simple input method cannot be used.

An object of the present invention is to provide a multi-input method using a keyboard and a pointer device, which allows input from the keyboard and input from a pointer device to be performed simultaneously.

[Means for solving problems]

The multi-input method from the keyboard and pointer device of the present invention includes a task generation process that generates a keyboard input task and a pointer device input task at the beginning of an input key routine, and a key code input from the keyboard that is sent to a mailbox. the pointer device input task that converts a pointer position input from a pointer device into a key code by referring to a key code conversion table and puts this key code into a mailbox; It has a key code setting process of getting a key code and setting it to a designated address.

[Effect]

In the multi-input method from the keyboard and pointer device of the present invention, the task generation process generates a keyboard input task and a pointer device input task at the beginning of the input key routine, and the keyboard input task is a key code input from the keyboard. into the mailbox, the pointer device input task converts the key code by referring to the key code conversion table at the pointer position input from the pointer device, gets this key code into the mailbox, and executes the key code setting process. Get the key code from your mailbox and set it to the specified address.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 3 is a block diagram showing an example of a hardware system configuration to which a multi-input method from a keyboard and a pointer device according to an embodiment of the present invention is applied. This system includes a CPUI for controlling processing, a display device 2 consisting of a CRT, and a keyboard 3 for performing key input.
Mouse 4, which indicates the position on the screen with a mouse on the screen that moves according to the movement, and random access memory (R
AM) 5, hard disk device (HDD) 6, floppy disk device (FDD) 7, and printer (PRT)
8.

Referring to FIG. 1, the processes in the input key routine 10 in the multi-input method from the keyboard and pointer device of this embodiment include a task generation process I, a keyboard input task II-A, and a mouse input task II-A. -B
and key code setting processing ■.

The task generation process f is a process for generating a keyboard input task II-A and a mouse input task II-B at the beginning of the input key routine 10.

The keyboard input task (IA) consists of a key input waiting step 11, a key input determination step 12, and a get mail step 13.

The mouse input task II-B consists of a pointer presence/absence determination step 21, a button press determination step 22, a key code conversion step 23, and a put mail step 24. The key code conversion step 23 converts the pointer position into a key code by referring to the key code conversion table 25 (see FIG. 2).

The address setting process ■ is the get mail step 31,
This step consists of a key code setting step 32. In the get mail step 31, when the key code is input into the mail box 33, the key code is obtained from the mail box 33.

Referring to FIG. 2, the key code conversion table 25 is as follows:
The icon type, which identifies whether the icons are arranged vertically or horizontally, and the width of the icon (if the icons are arranged horizontally) or the height of the icon (if the icons are arranged vertically) , the horizontal coordinate x start and the vertical coordinate Y start of the top left position of the icon menu, and the one direction coordinate X end and the vertical coordinate Y end of the bottom right position of the icon menu
and a correspondence table between indexes and key codes for specifying icons. In the case of this embodiment, each icon is provided with the same width or height horizontally or vertically, and the index can be easily obtained by performing an operation such as division on the pointer position of the mouse 4. .

Next, the operation of the multi-input method from the keyboard and pointer device of this embodiment configured as described above will be explained.

First, in the main routine, an icon menu is displayed on the display device 2 under the control of the CPUI. This determines the area of the icon where the pointer of the mouse 4 is to be set, and the mouse 4 becomes usable as an input device.

From this state, when the input key on the keyboard 3 or the button on the mouse 4 is pressed and the input key routine 10 is activated in the main routine, the internal task generation process I generates keyboard input tasks ~A and mouse input tasks II. -B is generated, and these two tasks operate in parallel as a multitask.

If the input key routine 10 is activated by the keyboard 3, a key input is determined after entering the key input waiting step and block 11 (step 12), and if there is no key input, the process returns to step 11 and the key input is If so, the key code is put into the mailbox 33 (step 13).

If the input key routine 10 is started by the mouse 4, the coordinate X5ta of the key code conversion table 25 is
rt, Ystatt, Xend and Yen
Based on d, it is determined whether the pointer is in the icon area (step 21). If the pointer is in the icon area, then it is determined whether the mouse 4 button is pressed (step 22). If there is no pointer in the icon area, or if there is a pointer but no button is pressed, the process returns to step 21. If the button is pressed in step 22, an index indicating which icon the pointer is located on is obtained using the key code conversion table 25, and this index is converted into a key code (step 23). .

The obtained key code is then put into the mailbox 33 (step 24).

Note that the keyboard input task n-A and the mouse input task n-B are deleted after the control passes through the tasks.

In the key code setting process ■, the keyboard input task II-A or mouse input task II is sent to the mailbox 33.
When the key code is obtained from -B, the put key code is obtained from the mailbox 33 (step 31) and set to the specified address (step 32).

Thereafter, the input key routine 10 is exited and control returns to the main routine.

In this embodiment, a case has been described in which the mouse 4 is used as the pointer device, but it goes without saying that other pointer devices such as a light pen may also be used.

Further, in this embodiment, a case has been described in which an icon menu is used as the function selection screen, but it goes without saying that other function selection screens such as a pull-down menu may be used.

〔Effect of the invention〕

As explained above, according to the present invention, the keyboard input task and the voice input task are run in parallel as a multitask, and the mailbox is used as a common data storage area between the tasks. This has the effect of allowing input to be made simultaneously from both the computer and the pointer device.
