Abstract

PURPOSE:To minimize the shifting of the signal point of a user and to retrieve and operate easily information by equipping the titled device with a touch panel on the scope of a television receiver to be used as an input device of the data. CONSTITUTION:A video signal 6 of a character or a pattern made by a video signal of a video disk 4 and a computer 3, is displayed from a superimposer 11 onto the scope of a television receiver 1. By touching with the finger directly on the part of a touch panel 10 corresponding to the position of the video or a menu displayed on the screen with the finger, the menu is selected, and video data are read from the video disk 4, and displayed on the screen of the television receiver 1. Each time respective video data are retrieved, the explanation of the video is displayed by the character and the pattern.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to interactive data retrieval, and particularly to an interactive video data retrieval device aimed at non-experts.

[Conventional technology]

FIG. 3 is a block diagram showing a conventional video data retrieval device, in which l is a television receiver, 2 is a keyboard, 3 is a computer, 4 is a video disk, and 5 is a display device CRT using a cathode ray tube.

6 is the video disc 4 signal, 7 is the computer 3
The character or graphic video signal produced by 8 is the keyboard 2
This is the keyboard signal.

Next, the operation will be explained. The video signal 6 of the video disc 4 is displayed on the television receiver 1, and the video signal 7 produced by the computer 3 is displayed on the CRT 5.

To search for video data that the user needs, first a menu created by the computer 3 is displayed on the cathode ray tube of the television receiver 1, and the user selects the information from the menu using the keyboard 2. Input to computer 3. On the other hand, computer 3 has video disk 4.
The video data thus read out is displayed on the screen of the television receiver 1.

[Problem that the invention seeks to solve]

Conventional video data retrieval devices were configured as described above, and the user had to move his/her viewpoint to the CRT, keyboard, and television receiver screen, and since the input device was a keyboard, it was difficult for non-specialists to do so. The problem with houses was that they were difficult to use.

This invention was made to solve the above-mentioned conventional problems, and provides an interactive video data retrieval device that can reduce the movement of the user's viewpoint and facilitate information retrieval operations. The purpose is to obtain.

[Means for solving problems]

The interactive Eirin data retrieval device according to the present invention superimposes a computer signal on the screen of a television receiver, and also has a touch channel mounted on the screen of the television receiver as a data input device. 0 [Function] Since all the information displayed in this invention is displayed on the screen of the television receiver, there is no need for the user to move his or her viewpoint significantly, and the information can be adapted to the display on the screen. The operator simply touches the desired location on the touch panel with his or her finger, and the necessary information is input into the computer.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. 1st
In the figure, the same reference numerals as in FIG. 3 indicate the same or equivalent parts, 10 is a touch channel, and 11 is a superimposer. 12 is a character or graphic video signal produced by the computer 3; 13 is a video signal from the superimposer 11; 14 is a control signal for the video disc 4 output from the computer 3; 8 is a signal from the touch panel 2 to the computer 3.
This is the signal input to the

Next, the operation will be explained. The video signal 6 of the video disk 4 and the video signal 6 of characters or figures produced by the computer 3 are displayed on the screen of the television receiver 1 by the imposer 11. The characters and figures created by the computer 3 are superimposed on the image of the John receiver 1.The user can search for the image data he/she needs by searching for the image displayed on the screen or at the position of the menu. Compatible touch panel
By directly touching the part O with a finger, a menu is selected, and the video data is read from the video disc 4 and displayed on the screen of the television receiver 1.

For example, we will explain the steps from displaying a world map to displaying a map of Tokyo.0 First, a world map is displayed on the screen of the television receiver 1, and the part of the touch panel 100 that shows Japan is displayed on the screen of the television receiver 1. By touching with your finger, a map of all of Japan is searched on the video disc 4, and displayed on the screen. map will be searched and displayed. Each time each piece of video data is retrieved, a description of the video is displayed by the computer 3 in text and graphics. This is a search by touching the video directly, but the same is true for a search using a menu.

FIG. 3 is a flowchart of the operation when searching for a map as described above, and it is assumed that a world map is displayed on the screen of the television receiver 1. If there is no touch panel IOK input data in step S1, wait for NO1 input,
If yes, proceed to step S2 and send the input data to the computer 3.0 The input data here are the (x-y) coordinates of the map of Japan on the screen. Next, the input data sent in step S3, that is, the 0C- of the point touched by the finger.
7) Find the address of the video disc 4 using the coordinates.

In step S4, it is determined in step S3 whether or not the corresponding Eirin data exists at the address. If there is no data, the process returns to step S1; if there is, the process proceeds to step S5, where the display color of the area touched by the finger (Japan map on the screen) is changed in order to allow the user to confirm the input data. At step 86, the corresponding video data (a map of all of Japan) is read from the video disc 4. In step S7, the computer 3 generates characters and figures to be superimposed on the corresponding video data.

Next, in step S8, the video signal 6 of the video disc 4 and the video signal 12 of characters and figures generated by the computer are transferred to the superimposer 11, where they are subjected to superimpose processing and then displayed on the television receiver 1. Display it on the screen. Next, the process returns to step 81 and waits for the next operation (search for a map of Tokyo).

In addition, although the case where a touch panel was used as a data input device was demonstrated in the said Example, a mouse|mouth or a voice input device may be used. In addition, in the above embodiment, the case of map search was explained, but it is also possible to
Public road guidance, tourist information, musical instrument performance, gymnastics, golf,
The same effect can be achieved as a video data retrieval device for testing, fishing, car driving lessons, car repair, plant system repair, etc.

〔Effect of the invention〕

As described above, according to the present invention, a touch panel is attached to the screen of a television receiver, and this is configured to be used as a data input device to search for images. This has the effect of making it possible to concentrate on the screen and making it easier to search for video data.
