Keyboard |
摘要 |
A keyboard assembly having keys which provide input signals to a processing unit includes a flexible printed circuit and underlying mat which enable the keyboard to be warped upward at its center by a system of cams which are driven by a controlled motor. Such warping induces rotation of the forearms of the user so as to have ergonomic value with respect to repetitive stress trauma.
