Abstract:
A method of utilizing raised parts on a keypad surface, called separation walls, is disclosed. Separation walls can help prevent unintended key hits so that keys can be smaller and be placed with higher densities on small devices. Separation walls with slits can also make light beam keypads operable with multiple fingers at a higher input speed.
