Abstract

PURPOSE:To execute such a non-plotting will transfer as indicating, tracing, etc., by providing a mechanism for transmitting and receiving pointing device information between each terminal, and displaying independently a cursor for following its information, respectively. CONSTITUTION:Information from a pointing device 30 is decoded by a managing part 29 and sent to a cursor control part 28, and a position of a local cursor 15 is determined and displayed on a device 24. Simultaneously, position information is sent out to the other party side terminal by an information transmitting/ receiving part 25. In such a state, when plotting of a character and a graphic is generated, it is sent out together with a voice to the other party side terminal from a communication control part 21 through a plotting information transmitting/receiving part 22. On the other hand, in the other party side terminal, receive data is separated into plotting information, pointing device information and voice information by the communication control part 21, and thereafter, the plotting information is displayed on the display part 24, and also, a position of a cursor 16 is displayed by a cursor control part 28. In such a way, such a will transfer as each talker indicates, traces, etc., the same image in real time can be executed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drawing communication terminal.

[0002]

2. Description of the Related Art In recent years, drawing communication represented by a field called telewriting has attracted attention. These are for transmitting / receiving character / graphic information at the same time as a voice call, and callers exchange information while changing the same image in real time.

[0003]

However, in the above-described conventional drawing communication, the only means of expression that the caller can make with respect to the image is drawing, and the desire to communicate without changing the image is transmitted.
In other words, no means of communication such as pointing and tracing was provided. However, when two or more people exchange their intentions using a drawing that is actually written on paper or a blackboard, the action for the corresponding drawing is a non-drawing action such as pointing or tracing rather than adding or deleting characters or figures. There was a problem that it was not possible to communicate smoothly because there were far more people.

The present invention solves the above-mentioned conventional problems, and an object of the present invention is to provide a drawing communication terminal capable of transmitting non-drawing intentions.

[0005]

In order to achieve the above object, the present invention provides a mechanism for transmitting and receiving pointing device information such as coordinates and movement amount between terminals, and a cursor for following a pointing device connected to itself. And a mechanism for independently displaying a cursor that follows the pointing device information transmitted from the partner terminal.

[0006]

Therefore, according to the present invention, it is possible to display, on the partner terminal, a cursor which moves exactly the same as the cursor on the operator terminal, which follows the pointing device of the operator terminal. This allows the movement of the cursor itself to be transmitted in both directions.

[0007]

FIG. 1 shows an image and a cursor displayed on a display device according to an embodiment of the present invention. In FIG. 1, 11 is a display device screen, 12 and 13 are menus including drawing tools, 14 is a drawing area, 15 is a cursor that follows the pointing device of the operator side terminal (hereinafter referred to as local cursor), and 16 is the other side. It is a cursor that follows the pointing device information transmitted from the terminal (hereinafter referred to as a remote cursor).

FIG. 2 shows the construction of a drawing communication terminal in one embodiment of the present invention. In FIG. 2, reference numeral 21 is a communication control unit for controlling a call with a partner drawing communication terminal device through a communication line, 22 is a drawing information transmitting / receiving unit, 23 is a drawing unit, and 24 is a drawing unit.
Is a display device, 25 is a pointing device information transmitter / receiver, 26 is a voice transmitter / receiver, and 27 is a receiver for inputting / outputting and transmitting / receiving voice. 28 is a cursor control unit, 29 is a pointing device management unit, and 30 is a pointing device.

Next, the operation of the above embodiment will be described with reference to FIGS.
Will be described. Pointing device manager 29
Decodes the information from the pointing device 30 and passes it to the cursor control unit 28. The cursor control unit 28 determines the position of the local cursor 15 from the information of the pointing device 30 and displays it on the display device 24, and at the same time, sends the position information of the local cursor 15 to the other terminal by the pointing information transmitting / receiving unit 25. When the local cursor 15 acts on the menus 12 and 13 managed by the drawing unit 23 to draw a character or figure, the drawing is performed on the display device 24, and at the same time, the drawing information is the drawing information transmitting / receiving unit. The data is sent to the communication control unit 21 by 22 and these data including voice are integrated by the communication control unit 21 and sent to the partner terminal via the communication line.

The data received from the communication line is the communication control unit.
It is separated by 21 into drawing information, pointing device information, and voice information. The drawing unit 23 acquires drawing information from the drawing information transmitting / receiving unit 22 and displays characters / graphics on the display device 24. As a result, it is reflected on the drawing receiving side terminal generated at the partner side terminal. The cursor control unit 28 acquires the position of the remote cursor 16 from the pointing device information transmitting / receiving unit 25, and displays the remote cursor 16 on the display device 24. As a result, the movement of the cursor on the partner terminal is reflected on the receiving terminal as the movement of the remote cursor.

[0011]

As is apparent from the above embodiment, the present invention is a bidirectional drawing in which character / graphic information is transmitted / received at the same time as a voice call, and callers exchange information while changing the same image in real time. In addition to the basic functions of communication terminals, it has the effect of enabling daily communication such as pointing, tracing, or tracing without destroying images.
