HAND-HELD POINTING DEVICE

摘要

One implementation provides a hand-held device (102) to control motion of a pointer (120) on a display (118). The device includes a shell (103), a pressure sensor (106), and an actuator (104). The shell is capable of being held by hand. The pressure sensor contains pressure sensitive zones (105 A-D) that are each associated with a direction of motion of the pointer on the display screen. The actuator is positioned to be manipulated by a digit of the hand holding the shell, and includes protrusions (202 A-D) that can each press against one of the pressure sensitive zones (232 A-D). When the actuator (104) is manipulated, at least one of the protrusions presses against one of the pressure sensitive zones to cause the pointer to move on the display screen in a direction determined by the direction of motion associated with the at least one pressure sensitive zone against which the at least one protrusions is pressed.
