Claim Text:
1. A non-contact sensing device, comprising: a sensor comprising a plurality of function key sensors having a plurality of non-overlapping field of views (FOVs), each FOV corresponding to a different function key; a function key sensor of the plurality of function key sensors constructed and arranged to detect a presence of a body part at in its field of view, and to generate a function key control signal in response to detecting the body part at the field of view, wherein the body part of a user activates a function key to which the FOV of the function key sensor corresponds without the user physically touching the function key; a processor that receives and processes the function key control signal and outputs a command according to an assigned task of the function key sensor to a remote apparatus under control of the non-contact sensing device in response to the processed function key control signal, wherein the processor further stores data of the function key for identifying the function key and associating the function key with the assigned task of the function key sensor; and a control spot generator that illuminates the non-overlapping FOVs corresponding to the function keys to visually distinguish the different function keys.
