ABSTRACT:
A hand-held control device which fits interchangeably into a user's right or left hand. An ergonomically correct housing allows the device to fit snuggly into the grasp of the users hand and be used without creating user fatigue. The operative element in the control device may be a trackball, joystick, touch pad, or other device that can be manipulated by the user's thumb and, in conjunction with one or more switches actuated by phalangeal regions of the fingers, provides functional equivalence to a standard computer mouse or trackball. An optional band or strap may be provided to secure the control device to the user's hand such that the fingers of the hand are available for other tasks without setting the control device down. The control device may communicate with a computer or similar apparatus by a wired cable or a wireless interconnection, typically an RF or IR connection.
