Abstract: A system and method are described for tracking the location and orientation of a user's feet for an augmented reality display. A depth sensor generates a depth map of a scene within the field of view of the depth sensor, the field of view containing at least a portion of the user. A processor is configured to identify a portion of the depth map as a candidate object for foot tracking, determine a central skeleton representation of the identified portion, determine a location of a toe of the user's foot and a location of an ankle of the user's foot, based on the central skeleton representation, and calculate an orientation of the user's foot based on the determine locations of the toe and the ankle.

Abstract: An augmented reality system is described for providing a user with a facility to try out virtual clothing or accessories. The system comprises a database storing data defining at least one augmented reality object and a set of associated audio clips, each audio clip in the set corresponding to a different characteristic, trait or parameter of an associated augmented reality object, a camera for imaging a scene containing the user, logic for detecting the motion of a feature within the scene, a display device for displaying an image of the scene in which an augmented reality object is superimposed, an audio processing module for selecting an audio clip associated with the superimposed augmented reality object, and an audio device for playing a sound associated with the augmented reality object, wherein the sound is varied in accordance with the detected motion.
