Disclosed are methods, circuits, apparatus, systems and computer executable code for providing a multimode touchless human machine interface (TLHMI). The TLHMI may include one or more touchless sensors to sense a position or a movement of a subject portion within a sensing zone of the one or more sensors. Tracking logic may receive an output of the one or more sensors and may track a position or movement of a portion of a computing platform user within the sensing zone. A user input generator may convert an output of the tracking logic into signals indicative of a user input and may provide the user input signals to a functionally associated computing platform.
