POINTING DEVICE FOR NAVIGATING A 3 DIMENSIONAL GUI INTERFACE

摘要

A pointing device for entering data into an information processing system for a 3-dimensional graphical user interface. The pointing device comprises: a switch mounted on a pointing device for producing a first signal during actuation by a vertical downward pressure on a first region of the switch; a circuit for coupling the first signal to a Z-axis on a display attached to the information processing system so as to control movement of information along the Z-axis presented on the display. In another embodiment, the switch produces a second signal by a vertical downward pressure on a second region of the switch; and a circuit for coupling the second signal to a Z-axis on the display so as to move information present on the display along the Z-axis in a direction opposite to that of the movement along the Z-axis in response to the first signal.
