Handgrip exercising, computer game controller

Abstract

A computer input device used simultaneously for amusement, physical exercise and strength measurement. The device consists of handgrips separated by a metal spring, a system of levers, a variable electrical resistor (potentiometer), conductor wires and a plug designed for insertion into the game controller socket of a home or arcade computer. The operator or player grasps and squeezes the handgrips of the device causing the levers to move the control arm of the potentiometer. The electrical resistance is varied an amount proportional to the amount of squeeze. The computer will run programs which "read" the potentiometer's resistance values and use these values to control the movement of graphic symbols on the computer's video display. For example, the operator will squeeze the handgrips to "throw", "hit" or "kick" a ball (for a distance and speed proportional to the squeeze) from one location of the computer's video display screen to a designated target at another location on the screen. The computer program will also measure, record and monitor the amount of physical exercise. The device in conjunction with a computer will provide exercise in a way that amuses and entertains the operator thereby promoting adherence to an otherwise boring program of physical therapy or development.
