Abstract

PURPOSE: To easily recognize a cursor within a display screen by displaying the cursor with emphasis if the change of the cursor position is not detected for a prescribed time. CONSTITUTION: The position of a mouse 3 is detected at every fixed time by hardware interruptions and the present position of the mouse 3 is stored in a register. Then a user operates the mouse 3 to detect whether a mouse cursor position is changed or not. When the mouse 3 is at pause, 1 is added to a time counter which is previously set at 0. Then it is decided whether the value of the time counter is larger than the time constant that is optionally set through an input part 1. If the value of the time counter is smaller than the time constant, the interruption processing is finished. Then it is decided that the mouse 3 is not operated for a prescribed time and the cursor is displayed with magnification if the value of the time counter is equal to or larger than the time constant.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display control method, and more particularly to a display control method for a mouse cursor in an information processing device.

[0002]

2. Description of the Related Art In the conventional mouse cursor display method, as shown in FIG. 2A, the mouse cursor 10 is displayed in a stationary state at a predetermined position on a display screen 20. Then, when the user attempts to perform a selection operation using the mouse, the user operates the mouse to move the mouse cursor 10 to a predetermined position on the screen 20 where an icon or the like is displayed and gives an instruction to the system. Is going.

[0003]

However, in the conventional display control method, when performing a selection operation with a mouse, it is first necessary to operate the mouse to confirm where the mouse cursor 10 is on the display screen 20. However, there is a drawback that it is difficult to recognize the mouse cursor 10 especially when the mouse cursor 10 is located at one corner of the display screen 20.

The display control method of the present invention has been made in view of such a problem, and an object thereof is to provide a display control method capable of easily recognizing a cursor on a display screen. Especially.

[0005]

Means for Solving the Problems The means of the first invention is as follows. The first detection step detects the position of the cursor on the screen. The second detection step detects whether or not the detected position of the cursor has changed. The highlighting step highlights the cursor when a change in the position of the cursor is not detected within a predetermined time. The means of the second invention is the means of the first invention, wherein the highlighting step enlarges and displays the cursor. The means of a third aspect of the invention is the means of the first aspect of the invention, wherein the highlighting step blinks the cursor.

[0006]

The operation of the means of the present invention is as follows. First, in the first detection step, the position of the cursor on the screen, for example, the mouse cursor is detected. Next, in the second detection step, for example, by comparing the contents of the register storing the current mouse position with the contents of the register storing the previous mouse position, the detected cursor Detects whether the position has changed. Then, for example, when it is detected that the position of the cursor does not change for a predetermined time or more by comparing the contents of the time counter arbitrarily set from the input unit, the cursor is highlighted, for example, enlarged display, Make it blink.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to FIGS. FIG. 1 is a block diagram showing the configuration of a display control device to which the present invention is applied. In the figure, reference numeral 2 is a CPU, which controls each part described below. An input unit 1 is composed of a keyboard or the like for the user to input data and to give a predetermined instruction to the CPU 2. For example, the data input by the user operating the input function keys of the input unit 1 is CP
It is displayed on the display unit 4 via the display control unit 5 under the control of U2. Reference numeral 3 denotes a mouse as a pointing device, which allows the user to operate the mouse 3 to move a mouse cursor, which will be described later, to a predetermined position where an icon or the like is displayed on the screen to instruct the system. You can

2A and 2B are views for explaining the outline of this embodiment. In this embodiment, when the mouse 3 is operated, the mouse cursor 10 in the display screen 20 is displayed in a normal size as shown in FIG.
When is not operated for a certain period of time, the mouse cursor 10 is enlarged and displayed as shown in FIG.

The above outline will be described in detail below with reference to the flowchart of FIG. First, the position of the mouse 3 is detected by a hardware interrupt at regular time intervals and is stored in the register Px for storing the current mouse position (step S1). Next, it is detected whether or not the position of the mouse cursor 10 is changed by the user operating the mouse 3. This is done by comparing the contents stored in the register Px for storing the current mouse position with the contents of the register Py for storing the previous mouse position (step S2). And 2
When the values of the two registers are equal, that is, when the mouse 3 is at rest, the process proceeds to step S3 and 0 is set in advance.
1 is added to the time counter T set to. Next, it is determined whether or not the value of the time counter T is larger than the time constant n arbitrarily set from the input unit 1. Then, while the value of the time counter T is smaller than the time constant n, this interrupt processing is ended. Then, the above steps are repeated for each interruption, and when the time constant n becomes equal to or becomes larger than the time constant n, it is determined that the mouse 3 has not been operated for a predetermined time, and as shown in FIG. The enlarged display is performed (step S5).

On the other hand, if the contents of the two registers are not equal in step S2, the process proceeds to step S6 and the contents of the register Px for storing the current mouse position is changed to the register for storing the previous mouse position. Substitute for Py. Then, it is determined whether or not the mouse cursor 10 is currently being enlarged and displayed (step S7), and if the mouse cursor 10 is being enlarged and displayed, reduction processing is performed in the next step S8, and as shown in FIG. It returns to the normal mouse size and is displayed. After the reduced display, or when the enlarged display is not performed in step S7, the process proceeds to step S9 and 0 is substituted into the time counter T to clear it.

FIGS. 4A and 4B are views for explaining a mouse display control method according to another embodiment. FIG.
(A) is a newly provided step S41, and it is determined whether or not the position of the mouse cursor 10 is outside the window frame. That is, the mouse cursor 10 moves to FIG.
As shown in (a), when it is outside the window frame, enlarged display is performed, but when it is not outside the window frame, enlarged display is not performed.

Further, in FIG. 4B, in step S42 newly provided, it is determined whether or not the position of the mouse cursor 10 is in the designated area around the screen. That is, the enlarged display is performed only when the mouse cursor 10 is in a predetermined designated area around the screen as shown in FIG. 5B. By doing so, it is possible to easily identify the mouse cursor 10 that has been unused around the screen for a certain period of time.

As described above, according to the present embodiment, when the mouse operation is paused for a predetermined time, the mouse cursor is enlarged more than the normal mouse cursor for highlighting. Therefore, the user can change the position of the mouse cursor. Easily recognizable.

Although the mouse cursor is magnified and highlighted in the above embodiment, the invention is not limited to this, and the mouse cursor may of course be displayed in blinking.

[0015]

According to the present invention, the user can easily recognize the cursor on the display screen.
