Patent number: 6670561Abstract: Digitizer pointer position data corresponds to the absolute coordinates of a digitizer tablet having coordinate axes, and so when a user wishes to use a digitizer pointer like a mouse, different procedures are imposed on the user, sometimes requiring unnatural hand movements. A psuedomouse coordinate input method consists of providing a digitizer or coordinate input system having a coordinates indicator (e.g., a puck) for manipulation by a user, a tablet which detects the position of the coordinates indicator, and a host computer connected to the tablet to receive the output of the tablet. When the user grasps and moves the coordinates indicator, a coordinate information detecting step occurs which causes the coordinates indicator's position to be detected by the tablet, and the tablet then generates coordinate information data including coordinate values of the coordinates indicator on the tablet before and after its movement or displacement.Type: GrantFiled: August 10, 2001Date of Patent: December 30, 2003Assignee: Wacom Co., Ltd.Inventor: Toshio Aoki

Publication number: 20020080124Abstract: A coordinate input method consists of a coordinate input system having a coordinate indicator time, a tablet which detects the position indicated by the coordinate indicator, and a host computer which obtains the coordinate data output by the tablet. A coordinate information detecting step occurs which, upon retention and displacement of the coordinate indicator on the tablet, causes coordinate information data to be detected by the tablet, with the coordinate information data including coordinate values of the coordinate indicator on the tablet before and after its displacement. During a data transmission step, the coordinate indicator information data which has been detected is transmitted to the host computer by the tablet. During an indicator coordinate access standard data acquisition step, the coordinate indicator information is received by the host computer and utilized as data while each of the coordinate axes of the coordinate indicator is designated as a standard.Type: ApplicationFiled: August 10, 2001Publication date: June 27, 2002Inventor: Toshio Aoki
