ABSTRACT:
A cushion that can be attached to an existing cursor pointing device (control stick) on a computer or keyboard, or be integrally formed with the cap during manufacture. The cushion is flexible enough to prevent tissue damage to the user's fingers due to repetitive motions over an extended period of use, yet firm enough to transmit the desired pressure to the control stick. The cushion designed to be used on an existing control stick can be applied with an adhesive to a cap, or with a frictional fit directly to the control stick. The cushions are designed to be easily installed and replaced when worn.
