Abstract
Systems and methods are disclosed for estimating speed and/or velocity for a portable device using an optical sensor. The optical sensor may capture a plurality of samples to be processed to estimate speed. The speed or velocity may be estimated based on a determined context and/or usage of the portable device. The estimated speed or velocity may be used to supplement other navigational solutions or may be used independently.
