USER DEFINED ACTIVE ZONES FOR TOUCH SCREEN DISPLAYS ON HAND HELD DEVICE

摘要

An application program installed in a hand held computing device such as a tablet computer presents a graphical user interface (GUI) on a touch screen display and receives touch input signals from the touch screen display. When an unintentional touch event is detected, the application switches from an active mode to a configuration mode. In the configuration mode, graphical tools are displayed on the touch screen display to enable a user to define or adjust the active zone of the touch screen display so as to exclude the area of the touch screen display touched by the hand that is grasping the hand held device. Interactive elements in the GUI are then rearranged so that the interactive elements are within the newly defined active zone.
