DCFirst Claim
1. A position sensing assembly comprising:
- an interactive surface element defining a surface;
at least one pixel array comprising a plurality of detector elements configured to detect electromagnetic radiation at a baseline level, the at least one pixel array being configured to sense a position of at least one object with respect to a surface thereof according to locations of ones of the plurality of detector elements at which at least one of an amount of radiation detected and a change in the amount of radiation detected exceeds a predetermined threshold, the at least one pixel array being configured to sense at least a position of the at least one object with respect to the at least one pixel array when the at least one object has at least a predetermined degree of propinquity to the at least one pixel array;
circuitry coupled to and receiving an output from the at least one pixel array receiving, the circuitry being configured to provide a non-imagewise input representing the position of the at least one object relative to the at least one pixel array; and
wherein the change in the amount of radiation detected results from ones of the plurality of detector elements detecting reflected light from the object in addition to detecting the radiation at the baseline level.

Abstract
An interactive assembly including at least one interactive surface element, at least a first region of the at least one interactive surface element having first user sensible functionality and at least a second region of the at least one interactive surface element having second functionality, different from the first user sensible functionality, input sensor functionality, including at least one input sensor located in propinquity to at least one of the at least one interactive surface element, operative to sense impingement of an electromagnetic radiation spot on at least one of the at least one first region and the at least one second region of the at least one interactive surface element and utilization functionality for employing outputs of the input sensor functionality in respect of impingement on either or both of the at least one first region and the at least one second region.
