Abstract
A method tracks a pose of an object in a field of view of a camera; derives movement of the display apparatus or movement in the field of view using at least one of: the sensor data and the image data; determines, using the processor, whether or not the derived movement exceeds a first threshold; if the derived movement exceeds the first threshold, continues tracking the pose of the object; and if the movement does not exceed the first threshold: (1) stops tracking the pose of the object and (2) displays, using the display, the image based on a previously derived pose of the object.
