Abstract

PROBLEM TO BE SOLVED: To prevent a mouse cursor from being missed even if a user does not operate a mouse device for a certain time, by masking the non-existing area of the mouse cursor if the mouse device is not moved for a prescribed time. SOLUTION: A start signal is sent to a mouse cursor decision means 103 if a mouse has not moved and the time counted by an internal counter exceeds a prescribed set time. The means 103 generates the information on a screen area where no mouse cursor exists by the received start signal based on the obtained coordinate of a mouse cursor and the information on a screen area management table that is managed at a screen management part 102. Then, the means 103 sends the screen area information to a mask pattern transfer means 104. The means 104 generates a mask pattern to mask the area where no mouse cursor exists on the display screen of a display device 3507 based on the screen area information and writes the mask pattern into a video memory 3505.

FIG. 12 is a diagram of a mask pattern example 2.

Reference numeral 101 denotes a mouse movement information management unit that monitors movement information from the mouse device 3501 and, when there is no movement information from the mouse device 3501 for a predetermined period of time, issues a start signal for masking a screen area to a mouse cursor determination. Means 1
Send to 03. A screen management unit 102 stores information for managing a screen area. Reference numeral 103 denotes a mouse cursor determination unit that transmits information on a screen area to be masked to the mask pattern transfer unit 104. The mask pattern transfer unit 104 generates a mask pattern and writes the generated mask pattern in the video memory.

Next, the operation of FIG. 1 will be described with reference to FIGS. 2, 7 and 8.

The mouse movement information management unit 101 monitors the movement information output from the mouse device 3501 in step 5 of FIG. In step 6, it is determined whether or not the mouse has moved. If the mouse has moved, the internal counter for counting the non-moving time is cleared, and the process returns to step 5. If there has been no movement, in step 7, the counted internal counter is compared with a preset time, and if not, the process returns to step 5. If exceeded,
An activation signal is sent to the mouse cursor determination means 103.

In step 8 of FIG. 2, the mouse cursor determination means 103 determines the coordinates of the mouse cursor acquired in step 5 and the screen area management table of FIG. According to the information,
Screen area information where no mouse cursor is present is generated and sent to the mask pattern transfer means 104. In step 9, the mask pattern transfer unit 104 generates a mask pattern for masking an area where the mouse cursor does not exist on the display screen of the display device 3507 based on the transmitted screen area information and writes the mask pattern in the video memory 3505.

[0065]

According to the present invention, since the non-existence area of the mouse cursor is masked when the mouse device has not been moved for a predetermined time, the mouse can be operated even when the user does not operate the mouse device for a predetermined time. It is possible to prevent the cursor from being lost.

Further, since the non-existence area of the mouse cursor is masked when the manual switch is pressed or a certain key is input from the keyboard device in the same manner, when the user loses the mouse cursor, When the manual switch is pressed or a specific key is input from the keyboard device, the area where the mouse cursor does not exist is masked, so that the mouse cursor can be easily found.

According to the present invention, a window for notifying the screen area where the mouse cursor is located is displayed, so that the user can know the screen area where the mouse cursor is located by looking at the window. It is easy to find the mouse cursor when you lose it, and you can prevent it from being lost.

According to the present invention, when the mouse device does not move for a predetermined time, the mouse cursor automatically moves to a specific display pattern, so that the user does not operate the mouse device for a predetermined time. However, it is possible to prevent the mouse cursor from being lost.

In a similar manner, the mouse cursor automatically moves to a specific display pattern when a manual switch is pressed or when a specific key is input from a keyboard device. When a manual switch is depressed or a specific key is input from a keyboard device when the user loses his / her eyesight, the mouse cursor automatically moves to a specific display pattern, so that the mouse cursor is easily found.
