1. A machine implemented method comprising:
- emitting electromagnetic energy from one or more emitters of a mobile device; and
estimating a range from said mobile device to a proximate surface based, at least in part, on spectral properties of reflected energy received by one or more sensors of said mobile device, said reflected energy including electromagnetic energy that was emitted from said one or more emitters and reflected from said proximate surface.

Abstract
A mobile device may determine a material-type of a surface proximate to the device and/or a distance between the device and the proximate surface, in at least one implementation. In some implementations, proximate material-type information may be used to estimate a distance between a mobile device and a proximate surface. A material class may also be determined for a proximate surface in some implementations. Various context-based applications are disclosed for material-type, material class, and/or distance information in connection with a mobile device.
