Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a shared screen system. More specifically, the present invention relates to a shared screen system shared on a communication network. More specifically, the present invention relates to a shared screen system that can be used for an education system using a communication network.

[0002]

2. Description of the Related Art As a conventional education system using a communication network, an education system using television broadcasting and radio broadcasting is known. On the other hand, there is also known an education system in which classrooms are set up in each region to provide individual guidance to students. Among them, a whiteboard, a blackboard and the like are used.

[0003]

However, an educational system using television broadcasting and radio broadcasting is intended for an unspecified number of students, and does not provide individual education to the students. Furthermore, the education provided is one-way from the instructor side, and any contact from the trainee to the instructor, such as a question, must be made by mail or other means. There was a problem that it was difficult to proceed simultaneously by making contact with the teacher and the lecturer from the student side. No use of a whiteboard to share the screen was made. On the other hand, in an educational system in which a classroom is set up and individual attendees are instructed, it is possible for the instructor to simultaneously contact the instructor and instruct the instructor to simultaneously proceed. However, in the same education system, the instructor and the student must be in the same place at the same time, and if the teacher and the student are located in different places or separated places, the time loss for moving may be lost. In addition, there was a problem that the possible time of the professor was also limited. Or
If the instructor and the applicants are located between remote locations, there is a problem that education is impossible in the first place.

[0004]

SUMMARY OF THE INVENTION According to the present invention, a lecturer and a student share a screen on a communication network using a communication network, and a person who writes on the screen uses a color not already used on the screen.
