Abstract:
A multiple coordinate controller device comprising:a three-dimensional body having a first surface portion and a second surface portion which is not coplanar with said first surface; a first transducer having a first sensing surface, said first transducer being coupled to said first portion of said body and being capable of detecting both positions and a range of pressure forces at said positions on said first sensing surface, wherein said first transducer is further capable of providing a first range of z coordinates at a detected x,y coordinate in response to said range of pressure forces on said first sensing surface, said first range of z coordinates provided only if said range of pressure forces are greater than a first threshold pressure; a second transducer having a second sensing surface, said second transducer being coupled to said second surface portion of said body and being capable of detecting both positions and a range of pressure forces at said positions on said second sensing surface, wherein second transducer is further capable of providing a second range of z coordinates of opposite polarity to said first range of z coordinates in response to said range of forces on second sensing surface, said second range of z coordinates provided only if said range of pressure forces are greater than a second threshold pressure.
