JPH0498514A - Pointing device control system - Google Patents

Abstract

PURPOSE:To enable a user to carry out his/her accustomed pointing operations and to secure the merits of a mouse and a tablet in the same system by attaining the simultaneous utilization of two pointing devices, i.e., the mouse and the tablet. CONSTITUTION:A main input control part has the pointing device information given from both tablet and mouse control parts. When both pointing devices, i.e., a tablet and a mouse are used simultaneously, these two devices must move a single cursor. In this respect, the tablet coordinates are read and converted into the coordinates of a screen to move the cursor to the corresponding position on the screen as long as a stylus pen is applied on the tablet. The mouse control part converts the displacement of the mouse into the coordinates of the screen only when the mouse is moved and then moves the cursor by an extent equal to the displacement of the mouse. Thus the screen cursor is moved by the tablet with the stylus pen kept on the tablet and by the mouse with the pen kept distant from the tablet respectively.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a pointing device control method.

[Conventional technology]

In this type of conventional pointing device control method, either a mouse or a tablet, or a mouse and a tablet are used by switching. This is because it is difficult to move (control the position) one cursor using multiple pointing devices.

FIG. 5 shows an outline of a conventional pointing device control method.

In FIG. 5, when there is an input request, the main input control section is brought into a state in which it can receive signals sent from the keyboard control section and the mouse control section. Then, when a keyboard input signal is received, control is transferred to the keyboard input analysis section, and when a mouse input signal is received, control is transferred to the mouse input analysis section, and the control is set to wait until the signal is received (pause). ).

At this time, the keyboard control unit is configured to transmit a keyboard input signal at the time of keyboard input (when the return key is pressed).

Further, when the mouse is moved, the mouse control section is configured to move a cursor on the screen by an amount corresponding to the amount of movement, and when a button is pressed, it is configured to transmit a mouse input signal.

If there is a keyboard input, the main input control unit receives the signal sent from the keyboard control unit, moves to the keyboard input analysis unit, and determines what key was pressed (
What kind of character string was input) is analyzed and used as input information.

Similarly, when there is a mouse input, the main input control unit receives the signal sent from the mouse control unit, moves to the mouse input analysis unit, and analyzes the cursor coordinates, the number of the pressed button, etc. Use as input information. Finally, the main input control unit sets the reception of keyboard input signals and mouse input signals to be disabled, passes the input information to the upper level, and ends the process.

[Problem to be solved by the invention]

In the conventional pointing device control method described above,
The system determines whether the pointing device is a mouse or a tablet, and the user cannot select the pointing device.

This has the disadvantage that the user cannot operate the CAD using a pointing device with which he or she is accustomed, and in some cases may be required to learn how to operate multiple pointing devices.

Another disadvantage is that the advantages of each pointing device cannot be utilized at the same time.

[Means to solve the problem]

The pointing device control method of the present invention includes: a tablet control means that allows a mouse and a tablet to be used simultaneously; a mouse control means that allows a mouse and a tablet to be used simultaneously; a means for simultaneously controlling a tablet and a mouse; and a tablet and a mouse. and means for controlling the position of one screen cursor with two pointing devices.

〔Example〕

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

FIG. 4 is a schematic diagram of the configuration of a general CAD system.

A general CAD system has each command that is visible to the user and a core part at a lower level.
Input/output control, screen control, etc. are performed in this core part.

FIG. 1 is a schematic diagram of one embodiment of the invention.

When there is an input request from a higher level CAD command, the core part receives it and sends it to the main input control part or the tablet control part.
It instructs each control section, such as the mouse control section, to "notify the main input control section if there is an input," and waits until there is an input. Each control unit determines whether there is an input, and if there is an input, notifies the main input control unit. In other words, the main input control section waits for pointing device information from both the tablet control section and the mouse control section.

Using two pointing devices, a tablet and a mouse, at the same time means that you have to move one cursor with the two pointing devices. Therefore, we changed the flow of the tablet control unit as shown in Figure 2, and when there is a stylus pen on the tablet table, we read the tablet coordinates, convert them to screen coordinates, and place the cursor at the corresponding position on the screen. It's moving.

Further, as shown in FIG. 3, only when the mouse is moved, the mouse control section similarly converts the displacement into screen coordinates and moves the cursor by the amount of displacement.

By doing this, if there is a stylus pen on the tablet table, the coordinates on the tablet will be read,
You can move the screen cursor depending on the tablet.
If the stylus pen is removed from the tablet, the coordinates of the tablet cannot be read, so the screen cursor can be moved using the mouse under mouse control.

In addition, the control unit (tablet control unit, mouse control unit) of each pointing device has a function of notifying the main input control unit when a button is pressed, so the main input control unit receives these button information and coordinate information ( By analyzing the coordinates (converted into the CAD coordinate system) and notifying the higher-level command unit, the user can perform CAD operations using a pointing device of his choice, either a tablet or a mouse.

〔Effect of the invention〕

As explained above, the present invention enables CA
By allowing users to use two pointing devices, a mouse and a tablet, at the same time, the D system allows users to perform all pointing operations with the pointing device they are familiar with, and also allows users to use the advantages of a mouse (easy button operations, cursor control, etc.) within the same system. -The advantage of being able to take advantage of the advantages of a tablet (such as being able to take your hands off the tablet after determining the position, etc.) is that you can paste rough shapes onto the tablet and input them by tracing them, you can use the tablet command menu, etc. be.
