ABSTRACT:
A cursor control device electrically connected to a computer is used for controlling movements of an object within a three-dimensional image displayed over a screen of the computer. The computer comprises a computer program for controlling display of the three-dimensional image over the screen and for moving the object within the three-dimensional image. The three-dimensional image comprises a first, a second and a third coordinates mutually perpendicular to each other. The cursor control device comprises a housing having a first panel and a second panel perpendicular to each other, a first cursor controller installed on the first panel for generating a first two-dimensional signal, and a second cursor controller installed on the second panel for generating a second two-dimensional signal. The computer program moves the object within a two-dimensional plane formed by the first and second coordinates within the three-dimensional image according to the first two-dimensional signal and moves the object within a two-dimensional plane formed by the second and third coordinates within the three-dimensional image according to the second two-dimensional signal.
