Abstract

ErgoPad is a design for an ergonomic touch pad that allows users to use a touch pad at the natural rest position of the hand. The natural rest position of the hand is vertical, with the palms parallel to the sides of the body. Many ergonomic mice and keyboards are now being developed ‘vertical’ (as opposed to the traditional ‘horizontal’ layout) to minimize wrist pronation, and thereby minimize Repetitive Stress Injuries (RSI).

4. General Description

There is a rapidly growing market for ergonomic computer peripherals ranging from mice to keyboards. The current 'horizontal' designs of mice and keyboards cause excessive arm pronation. Most of the new peripherals are designed to a 'vertical' design. This allows the users hand to remain at a rest position parallel to the sides of the body, a more natural posture. This can easily be demonstrated by standing straight and allowing your hands to dangle freely. In the natural position the palms lie parallel to the thighs, a natural position that minimizes arm pronation. Excessive pronation -which is characterized by cross over of the two bones in the forearm- occurs when using horizontal keyboards.
