Abstract:
1. A tracking product comprising: a plurality of coded data sources; an imager, the imager having a field of view, the field of view extending along each of three orthogonal axes, the field of view having a reference point, the imager being adapted to detect light concurrently from several coded data sources from the plurality of coded data sources when the several coded data sources are spatially separated in the field of view; a first coded data source from the plurality of coded data sources, the first coded data source being in the field of view at a first coded data source location relative to the reference point, the first coded data source representing a first coded data source identity, the first identity being represented by the first coded data source without any physical nor spatial nor temporal dependence on the representation of a second identity by a second coded data source from the plurality of coded data sources; a first track signal, the first track signal being caused when light from the first coded data source is detected by the imager, the first track signal representing the first coded data source identity, the first track signal representing the first coded data source location relative to the reference point.
