Abstract

This article describes a three-axis touch-sensitive pad for general computer input, cursor positioning and control. Much effort is being expended in the area of a simplified man/ machine interface. Menu-driven software, in which the user is presented a list of available options, is a common approach taken to achieve this simplification. Many hardware devices exist to make the selection task easier. Cursor control keys, mice, touch-sensitive screens (overlay on display) and touch-sensitive pads are common in the market place today. This disclosure deals with an improvement made to touch-sensitive pads. A touch-sensitive pad is a device consisting of a flat surface which represents a position on that surface (the location of a pointing object, such as a person's finger or a stylus) to the computer.
