Systems and methods for high resolution optical touch position systems

A method for determining a touched position within a bounded area, said method comprising:

• positioning an integrated array of interleaved emitters and detectors on opposing edges of said bounded area, and
• detecting by at least one detector on one array a signal sent from at least one emitter on said opposing array.

A touch position sensitive device comprising:

• a surface bounded by at least two integrated arrays of opposing alternating emitters and detectors;
• and
• means for determining a temporarily touched position with respect to said bounded surface.

A hand held device comprising:

• a plurality of integrated alternating signal emitters and signal detectors arranged to form arrays, said arrays positioned to define a display area;
• and
• a processor operable from signals emitted from at least one of said signal emitters and by at least one of said detectors for determining the relative position within said display area of a temporary intrusion between at least one signal emitter and at least on signal detector.

A device comprising:

• an interleaved set of emitters and detectors integrated onto a single substrate, said emitters operable for providing optic signals and said detectors operable for detecting optic signals.
