Abstract

PURPOSE:To directly indicate coordinates on a picture display by temporarily displaying a cursor at the prescribed position of a picture display, and moving it by an operating button or the like. CONSTITUTION:An operating part 1 is provided with an operating button 4 for point, and a command signal for displaying and moving a cursor CR on a picture display 5 of a receiver 2 is emitted from a light emitting part 3 by the operation of the operating button 4. At the time of pressing the central part of the operating button 4, the cursor CR can be displayed at a central position Co of the picture display 5. Also, at the time of pressing the peripheral part of the operating button 4 in up-and-down and right-and-left directions, the cursor CR can be moved to the directions. Triangular marks indicating the directions are displayed on the operating button 4 in order to clarify the moving directions. At the time of moving the cursor CR to the desired position by the operating button 4, and pressing the central part of the operating button 4 again, the pointing of the coordinates is operated. Thus, the coordinates on the display 5 can be directly indicated.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pointing device for designating coordinates on an image display, and more particularly to a pointing device for generating a command to an image display or a device displaying an image on the image display by designating the coordinates. Regarding the device.

2. Description of the Related Art While remote control of television receivers has become widespread, the repulsion of users to high-performance telephones is obvious, and it is necessary to find an optimum balance between high functionality and easy operation. It is important for product development. In this respect, the game machine has a feeling that the user is much closer to the user than a personal computer having a keyboard, but the penetration to the middle-aged and elderly people is limited, because of the input device such as a mouse and a keypad. However, the amount of information supplied to the user is increasing more and more, and it is difficult to suppress the sophistication of functions even if only the selection of information is selected. The output of the mouse and the like described above is indirectly reflected on the screen, so that it is not always easy for middle-aged and elderly people to be familiar with.

SUMMARY OF THE INVENTION The present invention was devised to solve the above-mentioned conventional problems, and provides a pointing device capable of directly indicating coordinates on an image display in a device having an image display. The purpose is to do.

[0004]

According to the pointing device of the present invention, a cursor is temporarily displayed at a predetermined position on the image display, and the cursor is moved by an operation button or the like to instruct coordinates on the image display.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, one embodiment of a pointing device according to the present invention will be described with reference to the drawings.

FIG. 1 shows an operating section 1 in one embodiment of a pointing device according to the present invention. This operating section also serves as a remote control device for a television receiver 2 (FIG. 2) and controls A light emitting unit 3 that emits infrared rays is provided.

The operation unit 1 is provided with a point operation button 4. By operating this operation button 4, a command signal for displaying and moving the cursor CR on the image display 5 of the receiver 2 is issued. Emitted from 3. The operation button 4 has a cursor CR when its center is pressed.
Is displayed at the central position Co of the image download play, and the cursor CR can be moved in that direction by pressing the upper, lower, left and right peripheral portions thereof. In order to clarify this moving direction, a triangular mark indicating the direction is displayed on the operation button 4. When the cursor CR is moved to a desired position by the operation button and the central portion of the operation button 4 is pressed again, the pointing of the coordinates is performed.

Here, the processing on the receiver 2 side for the command signal will be described. In the flowchart of FIG. 3, it is first determined whether or not there is a cursor display start command (whether or not the central portion of the operation button has been pressed) (step S1). If no command has been received, the process ends and a command is received. If so, the process proceeds to step S2 and thereafter.

In step S2, the cursor CR is displayed, and thereafter, "determination of presence / absence of upward movement command (step S3: whether or not upper edge of operation button is pressed)", "determination of presence / absence of downward movement command" (Step S5: Whether lower edge of operation button is pushed), "Determination of presence / absence of right movement command (Step S7: Whether right edge of operation button is pushed)", "Left movement command" According to the determination (step S9: whether or not the left edge of the operation button has been pressed), the cursor is appropriately moved in that direction and the coordinate value is increased or decreased. The above processing ends when the position confirmation command is issued (when the central portion of the operation button is pressed again) (step S11), and the coordinate value (X, Y) of the cursor CR on the image display is output. , The cursor is erased (step S12), and the process ends.

By the above pointing, the coordinates (X, Y) on the display 6 can be directly designated,
Operations corresponding to relatively advanced functions such as selection of a menu displayed on the display 6 and designation of a region can be instructed by an intuitively understandable instruction method. Therefore, a user-friendly man-machine interface can be realized, and the present invention can be applied not only to the television receiver but also to many devices having an image display. The image display 6 includes various display devices such as CRT, LCD, vacuum microdevice, and plasma display.

[0011]

As described above, in the pointing device according to the present invention, the cursor is temporarily displayed at a predetermined position on the image display and the coordinate is designated by moving the cursor with the operation button or the like. It has an excellent effect that the coordinates on the image display can be directly indicated in the device having the.
