Method and apparatus employing multi-functional controls and displays
Methods and apparatus are disclosed video displays that can sense finger, object or other control information proximate the display face. Electro-optical sensing is general employed, though some embodiments illustrate conventional electronic means. Diverse applications to vehicles, homes and control systems and the like are discussed.
1 . A method for displaying images and sensing the presence of finger touches or other object presence proximate the display face comprising the steps of:
providing a display capable of displaying both visible and near infrared pixels;
electro-optically detecting information reflected back toward the display face from said finger touches or objects; and
determining the presence and location of said fingers or objects using said information.
