  • LIGHT-TRANSMISSIVE KEY AND OPTICALLY-RECOGNIZABLE SIGNATURE
    Publication number: 20110074739
    Abstract: A machine vision input system includes a light-transmissive key including a base surface and an opposing touch surface. The base surface is configured to optically mate with a display surface so that images displayed on the display surface are viewable through the touch surface. An optically-recognizable signature is registered to the light-transmissive key for detection by an image capture device. The optically-recognizable signature provides machine vision differentiation from other optically-recognizable signatures while transmitting images displayed on the display surface for viewing through the touch surface of the light-transmissive key.
