Abstract

PURPOSE:To make it possible to indicate the specific part on a drawing to an opposite party by emphasizing it by changing the color, luminance or form of an indication mark. CONSTITUTION:The operation information inputted from an input device 1-3 is processed in a terminal control device 1-2 and is reflected to a display device 1-1. At the same time, the information is transmitted from a communication control device 1-4 to terminal equipments for other remote conference, the same processing is performed for the information in a terminal, control equipment 1-6 and it is reflected to a display device 1-5. Therefore, the same picture is always displayed on the display devices 1-1 and 1-5. When a user B indicates a character X on data to a user A, the coordinate value of the character X is inputted by using an input device 1-7 and an indication mark 2-2 is moved to the character X. When the input showing the emphasis of the indication mark 2-2 is performed, the color, luminance or form of the indication mark 2-2 is changed. Therefore, the user A can know that the user B indicated the character X.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote instruction system for instructing an arbitrary point on the screen of a display device in a remote conference system.

[0002]

2. Description of the Related Art In the prior art, Japanese Patent Laid-Open No. 2-17697
As described in Japanese Patent Laid-Open No. 6, in order to identify which instruction mark belongs to which user, the type of instruction mark is displayed differently for each user.

[0003]

The above-mentioned prior art does not consider emphasizing and instructing an already-indicated position, and the user wants to emphasize a specific portion on the screen to instruct the other person. Sometimes it is necessary to move the instruction mark,
There was a problem that it took time and effort.
Further, when the portion to be emphasized and instructed is a part of a detailed drawing, moving the instruction mark may cause the wrong portion to be conveyed to the other party.

An object of the present invention is to solve the problems of the prior art and to provide a remote instruction system in a remote conference system capable of emphasizing and instructing an instructed position.

[0005]

In order to achieve the above object, a plurality of information processing devices having input means such as a keyboard and mouse, display means such as CRT, control means and communication control means communicate with each other. Connected by a line, the same screen is displayed on the display means, and the coordinate values on the screen input from the self input means,
Based on the coordinate values on the screen input from the other input means transmitted by the other communication control means, the control means instructs the display means to display an instruction mark for indicating an arbitrary point on the screen. In the conference system, when there is an input indicating the emphasis of the instruction mark from the input means, the display of the instruction mark is changed.

[0006]

When the same coordinates as the coordinates where the instruction mark is already displayed are input, or when there is an input indicating the emphasis of the instruction mark, by changing the color or the brightness or the form of the instruction mark, It becomes possible for the user to instruct the other party by emphasizing a specific portion on the screen.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a block diagram of a remote conference system. The remote conference system is composed of a plurality of remote conference terminal devices connected by a communication line 1-9. Each remote conference terminal device includes a display device 1-1, 1-5, a terminal control device 1-2, 1-6, an input device 1-3, 1-7, a communication control device 1-4, 1-8. Have.

The operation information input from the input device 1-3 is processed by the terminal control device 1-2, and the output result is reflected on the screen of the display device 1-1. At the same time, the operation information is transmitted from the communication control device 1-4 to the other remote conference terminal device. The terminal control device 1-6 having received the transmitted operation information performs the same processing as the terminal control device 1-2, and reflects the output result on the display device 1-5. As described above, the same screen is always displayed on the display devices 1-1 and 1-5, and the terminal user can hold a conference while watching the same screen as the other party.

FIG. 2 is a diagram showing an example of a screen displayed on the display devices 1-1 and 1-5. Here, the display device 1
The screen example is -1. 2-1 is a conference material used in the conference. 2-2 is the other party's instruction mark. 2-3 is one's own instruction mark. The operation of the instruction mark is performed by the input devices 1-3 and 1-7 such as a mouse, for example, in the case of a mouse, a simple operation such as on / off of a button. When the coordinate value on the screen is input from the input device, the instruction mark moves to that position and is displayed. The instruction mark 2-2 is operated by the input device 1-7, and the instruction mark 2-3 is operated by the input device 1-3. In this embodiment, the arrow is used as the instruction mark, but other forms may be used.

Now, it is assumed that the user B inputs the coordinate value of the character X using the input device 1-7 in order to indicate the character X on the material to the user A. At this time, if the instruction mark 2-
If 2 is not at the position of the character X, the instruction mark 2-2 moves to the position of the character X, so that the user A can know that the user B wants to instruct the character X. Even if the instruction mark 2-2 is already at the position of the character X and the instruction mark 2-2 does not move, the color, brightness or form of the instruction mark 2-2 changes. User A
Can know that the user B has designated the letter X.

FIG. 3 is a flowchart of an embodiment of the present invention. First, in step 3-1, the input devices 1-3 and 1
From -7, read the coordinate value of the position you want to remote-instruct. The coordinate value read in step 3-2 is compared with the coordinate value of the current instruction mark. If the coordinate values are different, the instruction mark is moved to the read coordinate value and displayed in step 3-3. If the coordinate values are the same, in step 3-4 the color, brightness or form of the instruction mark is changed and displayed.
Then, in step 3-5, it is determined whether the input is continued, and if it is continued, the input is repeated. If it does not continue, it ends.

In the present embodiment, when the same coordinates are input, the color, the brightness or the form of the instruction mark is changed. The color, brightness, or form of the instruction mark may be changed by pressing the function key indicating.

[0014]

According to the present invention, since the color, the brightness, or the shape of the instruction mark is changed, it is possible to emphasize a specific portion on the screen that the other party wants to see and to give a remote instruction. ..
