Abstract

A remote operation system includes a computer, a projector means for projecting onto a screen pictures produced by application software installed on the computer, a first terminal and a plurality of second terminals. The first terminal selects one of the second terminals and allows the selected second terminal to operate application software. The selected terminal operates application software based upon such permission and operations of application software by the terminal are projected onto the screen. In the form of school lesson, the teacher allows students to operate application software while they are being seated.
