1. A method comprising:
energizing plural lamps one at a time;
detecting events from energizing the lamps using an event detector sensor (EDS); and
using output of the EDS to generate simultaneous localization and mapping (SLAM) information in an augmented reality (AR) environment at least in part by generating, from the SLAM information, plural motion hypotheses; and
selecting one of the hypotheses for use of the one of the hypotheses to execute SLAM.
