Method and apparatus for displaying multiple images on individual keys of a keyboard

Image Number 4 for United States Patent #8085244.

A key for an information handling system, the key including a finger surface configured for interaction with a user's finger and an inverted lenticular lens positioned beneath the finger surface. The finger surface may be substantially transparent to at least one wavelength of visible light. The inverted lenticular lens may include a first image and a second image. Light incident on the lens at a first angle of incidence may project the first image from the lens onto the substantially transparent finger surface of the key and light incident on the lens at a second angle of incidence may project the second image from the lens onto the substantially transparent finger surface of the key.
