ABSTRACT:
A computer system including a multi-device input system has a screen operation mode and a menu display item selection mode, to eliminate mode switching and achieve better operability. The computer system has: a display unit; a computer incorporating a regular processor and a menu selector; and a coordinate detector having a coordinate detection area superimposed with a menu display. The coordinate detector simultaneously detects coordinate information of two position pointing devices and supplies the coordinate information to the computer; a first position pointing device is exclusively used for selecting menu items from the menu display. A device for identifying position pointing devices detects the type of position pointing device being used on the coordinate detector. In response to the identifying device determining that the first position pointing device is used, the coordinate information about the first device is supplied to the menu selector and a symbol corresponding to the selected menu item is displayed. In response to the identifying device determining that a second position pointing device is being used, coordinate information about the second device is supplied to the regular processor so movement of the second device results in lines being drawn on the display.
