Abstract

PURPOSE:To easily and quickly perform the returning of an index to a pre scribed reference position, by changing the index being displayed on a display picture to a value representing a relative position for the reference position of the index when a prescribed indication means is operated. CONSTITUTION:The titled device is equipped with a memory means 51 which stores the relative position for the reference position of the index, an instructing means 53 which supplies instruction to return the index to a standard unit, and a control means 55 which changes the relative position of the index stored in the memory means 51 to the reference position according to the instruction from the instruction means 53, and returns the index to the reference position. It is assumed that (0, 0) is set as the coordinate value of a set reference position 21 of the index 20 on the display picture. When a mouse operation is performed, a CPU detects an operated quantity, and performs the arithmetic calculation of an absolute coordinate value (x1, y1) for the set reference position 21, and moved the index 20 to a position of (x2, y1). When an operation to return the index 20 to the set reference position 21 is performed in operating, the CPU resets a current absolute coordinate value (xn, yn), and changes it to (0, 0). In this way, the index 20 is returned to the set reference position 21.

Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention is intended for use in devices such as a so-called mouse or a trackball.
The present invention relates to an indicating device for indicating the position of an index on a display screen.

(Prior Art) In recent years, with the improvement in the resolution of display devices such as CRTs and the development of display software technology, it has become possible to display various types of complex and diverse graphics on display devices. With the realization of such complex and diverse display technologies,
2. Description of the Related Art Pointing devices such as so-called mice and trackballs have come into use for directly inputting various commands on a display screen.

(Problems to be Solved by the Invention) By the way, whether it is a mouse or a trackball, a reference position is usually set in advance on the display screen.
For example, a bright spot serving as an index is moved on the display screen by an amount proportional to the constant operated with respect to this reference position. However, this is troublesome because once the mouse or trackball is operated, the bright spot does not return to its reference position and the lifting platform must perform the necessary movement of the bright spot. Improvements were desperately needed in terms of simplicity and speed.

The present invention has been made in view of the above, and an object of the present invention is to provide an indicator position that makes it easy and quick to return an index to a predetermined reference position.

[Structure of the invention]

(Means for solving the problem) In order to achieve the above purpose, an instruction to calculate the relative position with respect to the reference position by a predetermined operation and move the index shown on the display screen by an extent proportional to this operation. In the apparatus, as shown in FIG. 1, the present invention includes a storage means 51 for storing a value indicating a relative position of the index with respect to a reference position;
instruction means 53 for giving an instruction to return the indicator to the reference position;
In response to an instruction from this instruction means 53, the storage means 51
It is necessary to have a control means 55 for changing the value indicating the relative position of the index stored in the index to a value indicating the reference position and returning the index to the reference position.

In the indicating device according to the present invention, when the predetermined indicating means is operated, the indicator shown on the display screen is changed to a value indicating the relative position of the indicator with respect to the reference position. By changing to , it returns to the standard position.

(Example) Hereinafter, the present invention will be explained in detail using the drawings.

FIG. 2 shows an embodiment in which the pointing device of the present invention is applied to a mouse. In the figure, reference numeral 1 denotes a microcomputer, which includes a CPU 3, a ROM 5. RAM 7. mainly stores the position coordinates of the index 20, which will be described later. It has a general configuration having input/output ports (Ilo>9).A mouse 11, a keyboard 13, and a CRT display 15 are connected to this microcomputer 1 via an input/output port 9. , the CPU 3 constitutes a control means, and the RAM 7 constitutes a storage means.The mouse 11 has a plurality of operation buttons 17 on its operation section 17.
-1.17-2.17-3, of which the operation button 17-3 constitutes an instruction means, and the indicator on the display screen that is moved in accordance with the operation of the mouse 17 is set in advance within the display screen. This is to instruct the user to return to the reference position set in .

Next, the operation of this embodiment will be explained using FIGS. 3 and 4. 3 shows an operational flowchart of the CPU 3, and FIG. 4 shows an example of a display screen on the CRT display 15.

In addition, the setting reference position 21 (
It is assumed that the coordinate values of (see FIG. 4) are set to (0, 0).

First, when the mouse 11 is operated while the index 20 is at the set reference position 21 (see FIG. 4), the CPU 3
detects the amount of operation, calculates the absolute coordinate value (χ+, V+> for the set reference position 21, and moves the index 20 to the position (χ+, '/+) according to this calculated value (steps 100 to 13o). .

Thereafter, until the operation button 17-3 is not operated,
Similarly to the above, the CPU 3 determines the absolute coordinate values (yn,
The index 20 is moved according to the calculation result of yn).

During such an operation, when the operation button 17-3 is pressed to return the index 20 to the set reference position 21, the CP
tJ3 is the current absolute coordinate value (yn.

yn) and change it to (0, O). As a result, the index 20 is returned to the set reference position 21 (steps 140 to 160).

Therefore, according to this embodiment, in order to return the indicator 20 to the set reference position 21, the user must press the operation button 17-
3 and there is no need to take the trouble to move the index 20 to the setting reference position 21 using the mouse 11, thereby reducing the operation effort and saving labor.

Note that although this example has been explained using a mouse,
The invention is not limited to this, and can also be applied to other trackballs, for example.

Further, in this embodiment, the operation button 1 constituting the command means is
7-3 is provided on the mouse body, but this is done solely in consideration of operability; for example, the return command means may also be configured on the keyboard, and furthermore, it may be used in conjunction with the operation buttons on the mouse body. Good too.

〔Effect of the invention〕

As explained above, according to the present invention, when a predetermined indicating means is operated for an index shown on a display screen, a value indicating the relative position of the index with respect to a reference position is changed to a value indicating the reference position. Since the index is returned to the reference position by this, it is possible to return the index to the predetermined reference position more easily and quickly than in the past.
