1. A device for manually entering information into a computer, comprising: pressure sensing means attachable proximate to the tip of a finger of a hand for generating a pressure signal corresponding to the pressure of the finger tip against a surface; position sensing means attachable proximate to the finger tip for generating a finger tip position signal corresponding to the position of the finger top over a surface relative to a reference position, said position sensing means further comprising: first acceleration sensing means attachable proximate to the finger tip for generating a first acceleration signal, the first acceleration signal being a function of the acceleration of the finger tip along a first axis; second acceleration sensing means attachable proximate to the finger tip for generating a second acceleration signal, the second acceleration signal being a function of the acceleration of the finger tip along a second axis, the second axis being different than the first axis; and means for relaying the pressure and first and second acceleration signals to the computer sufficient for the computer to calculate a position on the surface where the finger makes contact, said position corresponding to at least a portion of the information to be used by the computer.
