Abstract:
A pointing device for generating a plurality of computer input signals by a user's hand and control a cursor position on displays, the device being designed to prohibit a wrist stress and keep the wrist joint at safe and comfortable rest thus minimizing tension in the user's hand, avoid pain, fatigue, and computer generated repetitive strain injuries even during protracted periods of continuous use, comprising following mutually arranged elements:(a) a generally flat bottom member for stably translatably positioning the device on an underlying substantially horizontal surface; (b) a generally convex housing attached on top of said generally flat bottom member upon which to rest a hand; (c) said generally convex housing having a contiguous front, top, and rear surface, left and right side surfaces to support a relaxed user's hand and proximal phalanges of fore-, middle, and ring fingers; (d) means for controlling the cursor position; (e) a plurality of actuators for generating input signals; (f) at least one to three of said actuators are mounted adjacent to said front surface to be in proximity to the relaxed fore-, middle or ring finger in highly operable position so that the front actuators are activatable by the fingers out of their relaxed position, while the hand itself rests in its relaxed position; (g) the front actuators being designed to be sensitive to the finger moves directed substantially horizontally or vertically upward; (h) the front actuators being designed protected from activation by substantially vertical downward loads.
