<p>PURPOSE:To display a cursor at a position set on an extended line that is pointed by a pen or a finger. CONSTITUTION:An almost vertically extended projection point detecting means 15 detects the input coordinates Pv of a pressure contact type input tablet put on the display screen of a display device 4. A simple extended projecting point detecting means 16 detects the coordinates Pe of the point where the offset equivalent to the difference between the pressure contact position pointed by a pen, a finger, etc., in the (x) and (y) directions and the position set on an extended line pointed by a pen, a finger, etc., is given to the coordinates Pv. A cursor display means 3 displays a cursor including the position put on the coordinates Pe on the device 4. An almost extended projecting point control means 6 corrects the coordinates Pe as necessary.</p> |
