  • Patent number: 6489947
    Abstract: An ergonomic dual-section computer-pointing device, that includes a cursor control section fixedly and movably attached to an ergonomic hand support section, reduces stress and helps to prevent cumulative trauma disorder. The ergonomic dual-section computer-pointing device keeps the hand in a neutral position, which imitates the natural roll of the hand, the wrist and the forearm. The ergonomic dual-section computer-pointing device facilitates two fields of motion. In a first field of motion, the fingers, the hand, and the wrist are used to manipulate the cursor control section while the ergonomic hand support section remains substantially stationary. In a second field of motion, the arm and shoulder are used to move the cursor control section and ergonomic hand support section in unison. The cursor control section is fixedly and movably attached to the ergonomic hand support section by a coupler.
