ABSTRACT:
A hand support device for use with a computer pointing device relieves repetitive motion stress and includes a top surface, a bottom surface, and a perimeter surface connecting the top surface and the bottom surface. The top surface includes: a palm support region, that is an inclined planar surface; a little finger support portion extending from the palm support region; a thumb support region extending from the palm support region; a front index positioned on a side of the palm support region, and between the little finger and thumb support regions; and a side index adjacent to and extending from the palm support and thumb support regions. The bottom surface facilitates sliding of the hand support device on a work surface. The hand support device reduces stress and risk of injuries resulted from repetitive motions by encouraging the user of a computer pointing device to employ two fields of motion to control the pointing device. The user engages the fingers, the hand, and the wrist to make fine movements while holding the hand support device stationary. The user moves the computer pointing device and the hand support device in unison with the arm and shoulder when making coarse movements.
