Abstract

PURPOSE:To directly indicate coordinates on a picture display by displaying the same picture as the picture display on the compact display of an operating part, and transmitting it by operating pointing to the compact display. CONSTITUTION:An operating part 1 is provided with a pen 7 for point, and at the time of indicating the surface of a display 5 with the pen 7, the coordinates on the display 5 are indicated, and the coordinates correspond to the coordinates(X, Y) of a picture display 6. As the detecting means of the coordinates of the display 5, for example, a transparent rubber whose electric resistance is changed according to pressurization is adhered to the surface of the display 5, and the decrease of a voltage is measured around. Coordinate values detected as mentioned above are transmitted from a light emitting part 3 to a receiver 2, and the pointing of the coordinates of the receiver 2 is operated. Thus, the coordinates on the picture display 6 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]

A pointing device according to the present invention displays the same image as an image display on a small display of an operation unit, performs pointing on the small display, and transmits the pointing to the image display side. It is a thing.

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 unit 1 in one embodiment of a pointing device according to the present invention, which operating unit is a television receiver 2
It also serves as the remote control device (FIG. 2) and is provided with a light emitting section 3 for emitting infrared rays for control. The operation unit 1 is provided with an antenna 4 for receiving television radio waves, and a small display 5 for displaying an image of a broadcast selected by the receiver 2. Therefore, the image displayed on the image display 6 (FIG. 2) of the image receiver 2 can be confirmed on the operation unit 1, and direct pointing can be performed as follows.

A point pen 7 is provided on the operation unit 1, and when the user points the surface of the display 5 with this pen 7,
The coordinates on the display are designated, and these coordinates correspond to the coordinates (X, Y) of the image display 6. As a means for detecting coordinates in the display 5, a) a structure in which a transparent rubber whose electric resistance changes by pressing is attached to the surface of the display 5 and the voltage drop is measured in the surroundings. b) A configuration in which the scanning line of the display 5 is detected by the pen 7 and the coordinates are calculated based on the position of the scanning line and the detection timing. c) A configuration that emits an infrared beam horizontally and vertically along the surface of the display 5 and detects the infrared beam at a facing position by a sensor to detect interruption of the infrared beam by a pen, and calculates coordinates based on this. . Alternatively, other known configurations may be adopted.

The coordinate value detected in this way is used as the light emitting unit 3.
Is transmitted to the receiver 2 and the pointing of the coordinates (X, Y) of the receiver is realized.

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. Image display 6 here
Includes various display devices such as CRT, LCD, vacuum micro device, plasma display, etc., and LCD is generally used as the display 5.

As described above, since the same image as the image on the image display is displayed on the operation unit and the pointing result for this is transmitted to the image display side, direct display coordinate instruction is possible and a user-friendly man. It can realize a machine interface and can be adopted not only in a television receiver but also in many devices having an image display.

Further, the operation unit 1 has a function of reproducing a voice signal of a received radio wave, and is provided with a button 8 and a speaker 9 for adjusting the volume thereof. Therefore, the operation unit 1 can be used alone as a portable television.

The supply of the video signal to the operation unit 1 may be received by wire from the outdoor antenna or the receiver 2.

[0012]

As described above, the pointing device according to the present invention displays the same image as the image display on the small display of the operation unit, performs the pointing on the small display, and transmits it to the image display side. Therefore, in a device having an image display, it has an excellent effect that coordinates on the image display can be directly designated.
