Abstract

PURPOSE:To erase a mouse cursor at the time of not operating a mouse for a certain time or longer by monitoring not only whether information of the mouse cursor is changed or not but also the continuation state by a display information storage buffer, a preceding display information storage buffer, and a timer. CONSTITUTION:The contents of an input information acquisition buffer (d) where information of the mouse cursor is stored are stored in a display information storage buffer (c), and it is monitored whether the state of information of the mouse cursor is changed or not by this buffer (c) and a preceding display information storage buffer (b). A mouse cursor display timer (f) monitors the continuation state of change/non-change of the state. If the timer (f) detects that the state is not changed for a certain time, the mouse cursor is erased from a display part (a); otherwise, the mouse cursor is displayed on the display part (a). Thus, the mouse cursor is erased when the mouse is not operated for a certain time or longer, and the cursor is displayed when the mouse is operated, and display data on the picture is always made easy to see.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mouse cursor display system, and more particularly to a mouse cursor display system for controlling the display of a cursor on the screen of a display terminal used in a computer system.

[0002]

2. Description of the Related Art Conventionally, a mouse cursor has been continuously displayed at the same position on the screen even when the coordinate movement by the mouse does not occur.

[0003]

In the above-mentioned conventional mouse cursor display method, the mouse cursor on the screen is always displayed even when the mouse is not operated (moved or clicked) and is displayed on the screen. There was a problem that the data and the mouse cursor overlap and the data on the screen was difficult to see.

An object of the present invention is to provide a mouse cursor display method that makes it easy to see the data on the screen by outputting the screen data without the mouse cursor when the mouse is not operated (moved or clicked) for a certain time or longer. It is in.

[0005]

According to the mouse cursor display system of the present invention, in a display device having an input means by a mouse, a buffer for storing information of the mouse cursor input by the input means and a buffer for storing the information in the buffer. A monitoring means for monitoring the presence / absence of a change in the state of the mouse cursor information, and a mouse cursor display timer for monitoring the continuous state of the presence / absence of a change in the state of the mouse cursor information detected by the monitoring means. When the mouse cursor display timer detects that there is no change in the state for a predetermined time, the mouse cursor is erased from the display unit of the display device, and when the monitoring means detects that there is a change in state. A mouse cursor is displayed on the display unit of the display device.

[0006]

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the mouse cursor display system of the present invention.

Referring to FIG. 1, a display device having a mouse input means includes a display section (a), a previous display information storage buffer (b), a display information storage buffer (c), and an input information acquisition buffer. (D) and input device (mouse)
(E), a mouse cursor display timer (f), input data D1, and display data D2.

In the display device having a mouse input means, when the operator inputs the data D1 from the input device (mouse) (e), the input data D1 is stored in the input information acquisition buffer (d). Next, the stored data in the input information acquisition buffer (d) is converted into display information and stored in the display information storage buffer (c), where it is compared with the data in the previous display information storage buffer (b). Data in previous display information storage buffer (b) and display information storage buffer (c)
When the data of the above is different, that is, when the mouse is operated (moved or clicked), the data in the previous display information storage buffer (b) is updated to the data in the display information storage buffer (c), and the mouse cursor is updated. Display data D2
Is output to the display unit (a). At this time, the mouse cursor display timer (f) is set to a constant value and the countdown is started.

On the other hand, when the data in the previous display information storage buffer (b) and the data in the display information storage buffer (c) are the same, the mouse cursor display timer (f) is checked. When the countdown mouse cursor display timer (f) set to a constant value is 0 or less, the display data D2 without the mouse cursor is output to the display unit (a). If the countdown mouse cursor display timer (f) set to a constant value is not 0 or less, the display data D2 with the mouse cursor is output to the display unit (a).

The above check is repeated. Therefore, mouse operation (move or click) for a certain period of time
Even if the data without the mouse cursor is output to the display unit (a) without performing, the data with the mouse cursor is output to the display unit (a) when the mouse operation (move or click) is performed again, Resume displaying the mouse cursor.

As described above, the present invention has an advantage of making it easy to see the display data on the screen by displaying the data without the mouse cursor unless the mouse is operated (moved or clicked) for a certain period of time. .

[0013]

As described above, according to the mouse cursor display method of the present invention, the mouse cursor can be erased when the mouse operation (move or click) is not performed for a certain time or longer, and the mouse operation (move or click) is performed. The mouse cursor can be displayed, and the display data on the screen is always easy to see.

Claims (1)

[Claims] 1. A display device having a mouse input means, and a buffer for storing mouse cursor information input by the input means, and whether or not there is a change in the state of the mouse cursor information stored in the buffer. And a mouse cursor display timer for monitoring the continuous state of the presence or absence of a change in the state of the mouse cursor information detected by the monitoring means, and the mouse cursor display timer has a predetermined constant time. When the absence of the state change is detected, the mouse cursor is erased from the display unit of the display unit, and when the monitoring unit detects the presence of the state change, the mouse cursor is displayed on the display unit of the display unit.
