A hand-held computer input pointing device (100) has at least one motion detector (314), the at least one motion detector being capable of detecting motion in at least three dimensions. At least one pressure sensor (316) is capable of sensing pressure quantitatively. The input device is operable within a hand of a user to transmit signals from the motion detector and the pressure sensor, without contacting a base, work surface or pad. The pointing device may, for example, be used to control a computer (701) executing a program to display a movable virtual puppet (710). |
