Abstract

See full text

A XY control system for controlling vector movement in two mutually perpendicular directions (for example for computer cursor control, i.e. emulating a conventional computer mouse) uses a XY pressure sensitive digital pad or more preferably a XYZ pressure sensitive digital pad generating different signals based on the selected location at which pressure is applied to the pad. These signals are divided into X or Y and a directional signal and then converted into a velocity signal for controlling the vector motion in the required direction dependent on the selected location for application of pressure to the pad and at a velocity the magnitude of which is proportional to the displacement of the selected location from a datum area on the pad, or in the case of a XYZ pad dependent on both displacement and the amount of pressure applied at the selected location.
