Patent attributes
An augmented reality system with encoding light emitting beacons placed in a scene. Beacons placed at desired locations in a scene emit light modulated with multiple access encoding that conveys an identifier for its emitting beacon. The emitted light signals are also blanked for longer than a time between image capturing by an image augmenting device. Beacons viewed in captured images are identified by correlating an absence of a beacon in an image with an absence of a received identifier in received light signals. In a view of the scene presented to a user, augmenting images are obtained based upon the determined beacon identifier and are displayed at locations in the scene based upon the determined location of that beacon. Beacons that emit pulsed light signals encoded with the multiple access coding are also provided.
