Abstract
A display system includes a sheet member onto which information is input, and a position coordinate detector such as a pressure sensitive touch panel. The position coordinate detector is formed as a body separate from the sheet member and is arranged behind the sheet member. It detects the position of information input on the sheet member. A computer, to which the output data of the position coordinate detector is transferred, processes the information input to the sheet member. When the sheet member is used as a projection screen, the computer connects to a projector to project the input information onto the sheet member.
