Abstract
An electronic device includes a laser source configured to direct laser radiation toward a user's hand. A laser detector is configured to receive reflected laser radiation from the user's hand. A controller is coupled to the laser source and laser detector and configured to determine a plurality of distance values to the user's hand based upon a time-of-flight of the laser radiation, calculate a mean absolute deviation (MAD) value based upon the plurality of distance values, and identify whether the user's hand is moving in a first or second gesture based upon the MAD value.
