1. An interactive assembly comprising:

  • 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;

    at least one input sensor located in propinquity to at least one of the at least one interactive surface element, each of the at least one input sensor being configured to provide an output indicative of an 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;

    utilization circuitry coupled to the output of each of the at least one input sensor;

    wherein the at least one input sensor includes a detector assembly arranged at at least one edge of the interactive surface element;

    wherein the detector assembly includes a support substrate and an arrangement of detector elements; and

    wherein the arrangement of detector elements is configured to detect electromagnetic radiation at a baseline level and to sense a position of at least one object with respect to the interactive surface element and wherein the utilization circuitry is further configured to provide an output according to a location of at least one detector element in the arrangement for which at least one of an amount of radiation detected and a change in the amount of radiation detected exceed a first predetermined threshold.
