Abstract
An electronic device includes at least one laser source configured to direct laser radiation toward a user's hand. Laser detectors are configured to receive reflected laser radiation from the user's hand. A controller is coupled to the at least one laser source and laser detectors and configured to determine a set of distance values to the user's hand for each respective laser detector and based upon a time-of-flight of the laser radiation. The controller also determines a hand gesture from among a plurality of possible hand gestures based upon the sets of distance values using Bayesian probabilities.
