Abstract
An infrared sensing assembly for allowing detection of a location of an external object, as well as a mobile device employing such an assembly and related methods of operation, among other things, are disclosed. In one exemplary embodiment, the sensing assembly includes a pyramid-type housing structure having a central surface and multiple outer surfaces each of which extends in an inclined manner away from the central surface. The sensing assembly further includes multiple phototransmitters each positioned proximate to a respective one of the outer surfaces, and a photoreceiver positioned proximate to the central surface, with each respective photoelectric device being oriented so as to correspond to its respective surface. The sensing assembly is operated so that light is emitted from the phototransmitters, reflected by the object, and received by the photoreceiver. By processing signals from the photoreceiver that are indicative of the received light, the external object's location is determined.
