ACOUSTIC CONDITION SENSOR EMPLOYING A PLURALITY 0F MUTUALLY NON-ORTHOGONAL WAVES
First Claim
1. A touch input system, comprising:
- a surface which is neither planar nor a small solid angle section of a sphere, adapted to receive a touch input from a human finger;
a sensor adapted to detect a touch and produce at least one signal representing a unique position of the touch input on the surface;
a processor, adapted to receive the at least one signal and produce an output representing a touch detection and a mapping of a coordinate position on the surface.

Abstract
A touch input system, comprising a surface, adapted to receive at least one simultaneous touch inputs from human fingers; a sensor adapted to detect the at least one touch inputs and produce at least one signal representing a unique position for the at least one touch input; and a processor, adapted to receive the at least one signal and produce an output representing a touch detection and a mapping of a coordinate position on the surface for each of the simultaneous touch inputs. The system may detect, for example, two touch inputs simultaneously. The surface may be non-planar and distinct from a small solid angle section of a sphere.
