Abstract
A mobile device configured to modify the mobile device's behavior based on the local environment of the mobile device. The mobile device determines the local environment based on a comparison of sound detected by the mobile device's audio sensor to sound detected by an exterior audio sensor. In particular, the mobile device determines if it is covered and, if covered, the mobile device determines properties of the covering material.
