<p>A display system of the present invention includes a sheet member (20) onto which information is input, position coordinate detecting means (10), such as a pressure sensitive touch panel, which is formed as a body separate from the sheet member (20) and is arranged behind the sheet member (20) and detects the position of information input on the sheet member (20), and a computer (104), to which the output data of the position coordinate detecting means (10) is transferred and which processes the information input to the sheet member (20). When the sheet member (20) is used as a projection screen, the computer (104) connects to a projector (106) to project the input information onto the sheet member (20). The sheet member preferably has a plurality information input surfaces. <IMAGE></p> |
