Claim:
An input device adapted for receiving an x-y input and input from at least one input actuator on the input device; the input device comprising: a) a housing adapted for use independent of any solid surface beyond the user's hand; b) the housing comprising a main body section with a long axis substantially parallel to a line in the body of a user grasping the pointing device running through the forearm of the user to the tip of the user's extended thumb; c) the housing further comprising a platform for containment of an x-y input device, the platform placed to be protruding outward from and substantially perpendicular to and slightly skewed to one side of the long axis of the main body section; d) the housing having a channel for placement of the user's index finger; e) the housing having a channel for placement of the user's middle finger; f) the channels positioned to place the user's index and middle fingers below and substantially orthogonal to the orientation of the user's thumb while the user is grasping the device; g) an input actuator being integrally formed into a recessed portion of at least one of the channels; and h) an x-y input sensor placed at the end of the input device, distal to the user's wrist, such that the x-y input is provided to the x-y input sensor by movements of the thumb primarily comprised of circumduction of the thumb's basal joint.
