Abstract

A technique is described for an improved man-machine interface control, whereby a variable position trigger mechanism is used in conjunction with a direction indicating mechanism to create an integrated device useful in the process of transmitting digital signals so as to represent manual inputs from an operator to a digital processor. The mechanism is unique in that it combines trigger and controls into an integrated mechanism. It provides a multi-variable interface to software algorithms of a digital processor. In prior art, joystick, keyboards, touchpads, mice, lightpens, etc. were used as devices to interface a user with a digital processing system. A typical input-output path, when using these devices, required the operator to actuate the control device so as to produce the required electrical signals.
