Will the orbiTouch cause damage to other parts of the arm given that it eliminates finger motion and wrist motion?

Extensive research has lead to the design of the orbiTouch Keyless Keyboard. Each orbiTouch dome moves 7 millimeters from their center position. This distance is about the same that most typists move their hands in typing on a regular keyboard. As such, the biomechanical requirements in the upper arm in using a regular QWERTY keyboard are similar to those when typing with the orbiTouch.
