Abstract
A tracked device may be used in an extended reality system in coordination with a tracking device. The tracked device may be ordinarily difficult to track, for example due to changing appearances or relatively small surface areas of unchanging features, as may be the case with an electronic device with a relatively large display surrounded by a thin physical outer boundary. In these cases, the tracked device may periodically present an image to the tracking device that the tracking device stores as an indication to permit tracking of a known, unchanging feature despite the image not being presented continuously on the display of the tracked device. The image may include a static image, designated tracking data overlaid on an image frame otherwise scheduled for presentation, or extracted image features from the image frame otherwise scheduled for presentation. Additional power saving methods and known marker generation methods are also described.
