Abstract
Disclosed are a coordinate input system and a method of controlling the coordinate input system, which can protect work of a user under progress against troubles even when the user touch an operating surface of a pad by mistake during key input operation on a keyboard. When the user operates a coordinate detecting device (PD) such as a pad, the operating action is sent to a coordinate outputting device (PC) such as a personal computer and analyzed by a data analyzer (12). If the user enters key inputs through a keyboard (19), a controller (15) instructs a mode converter (13) not to inform the operating action detected and sent from the data analyzer (12). After that, the controller (15) clears a timer built in a measuring unit (14) each time an key input is entered. Subsequently, if the key input operation is stopped, the measuring unit (14) actually starts counting of the timer. If the timer value exceeds a certain threshold, this is informed to the controller (15). In response to this notice, the controller (15) instructs the mode converter (13) to resume notice of the operating action detected and sent from the data analyzer (12).
