ABSTRACT:
A system for identification and tracking of a tag distributed in a room is presented. A laser base station is configured to scan laser beams through a portion of a room. A tag is configured to be reactive to incident laser beams scanned from the laser base station to provide a data signal back to the laser base station. A tag tracking system is configured to receive input derived from the data signal from the laser base station. The tag tracking system stores state records of position and informational content of the tag generated from the input. The tag tracking system determines angular position of the tag with respect to the laser base station based on the position and information content of the tag stored in the state records.
