Abstract
Methods and systems for displaying a computer generated image corresponding to the pose of a real-world object in a mixed reality system. The system may include of a head-mounted display (HMD) device, a magnetic track system and an optical system. Pose data detected by the two tracking systems can be synchronized by a timestamp that is embedded in an electromagnetic field transmitted by the magnetic tracking system. A processor may also be configured to calculate a future pose of the real world object based on a time offset based on the time needed by the HMD to calculate, buffer and generate display output and on data from the two tracking systems, such that the relative location of the computer generated image (CGI) corresponds with the actual location of the real-world object relative to the real world environment at the time the CGI actually appears in the display.
