Abstract:
A computer pointer control device for persons with limited dexterity comprising:a base having a top surface; a translation device positioned in said top surface of said base; a cradle having a front end, a back end, a bottom surface shaped to mate with said top surface of said base and contact said translation device, and a top surface adapted to accept a human limb; said translation device adapted to detect movement of said cradle within said base; a circuit for converting said detected movement into control signals for a computer device, whereby movement of said cradle is translated into control signals for said computing device; and an extension projecting upwardly from said base and in front of said front end of said cradle, said extension having at least one button positioned in front of said cradle, whereby an operator of said apparatus may operate said button with said limb; wherein said top surface of said base and said bottom surface of said cradle are semicylindrical and mating whereby movement of said cradle along a longitudinal axis of said partially cylindrical top surface is converted into control signals corresponding to a first direction and rotation of said cradle about said longitudinal axis is converted into control signals corresponding to a second direction orthogonal to said first direction.
