First Claim
1. A touch screen display system comprising:
- a display screen positioned in a first plane;
a touch surface positioned in a second plane adjacent to the display screen;
an illumination source configured to illuminate the display screen and the touch surface;
a first imaging sensor positioned in the second plane configured to detect an object coming in contact with the touch surface;
a second imaging sensor positioned in the second plane configured to detect the object coming in contact with the touch surface; and
an imaging system electrically coupled to the first and second imaging sensors and configured to receive electrical signals from the first and second imaging sensors relating to the detection the an object coming in contact with the touch surface, the imaging system also configured to detect an angular position on the touch surface of the object coming in contact with the touch surface based upon the received electrical signals.

Abstract
A touch screen display system includes a display screen positioned in a first plane. A touch surface is positioned in a second plane adjacent to the display screen. An illuminating source is configured to illuminate the display screen and the touch surface. A first imaging sensor is positioned in the second plane and configured to detect an object coming in contact with the touch surface. A second imaging sensor is positioned in the second plane and configured to detect an object coming in contact with the touch surface. An imaging system is electrically coupled to the first and second imaging sensors and configured to receive electrical signals from the first and second imaging sensors relating to the detection of the object coming in contact with the touch surface. The imaging system configured to determine an angular position on the touch surface of the object coming in contact with the touch surface based upon the received electrical signals.
