Abstract: Multi-player co-located AR experiences are augmented by assigning characters and costumes to respective participants (a.k.a. “users” of AR-enabled mobile devices) in multi-player AR sessions for storytelling, play acting, and the like. Body tracking technology and augmented reality (AR) software are used to decorate the bodies of the co-located participants with virtual costumes within the context of the multi-player co-located AR experiences. Tracked bodies are distinguished to determine which body belongs to which user and hence which virtual costume belongs to which tracked body so that corresponding costumes may be assigned for display in augmented reality. A host-guest mechanism is used for networked assignment of characters and corresponding costumes in the co-located multi-player AR session. Body tracking technology is used to move the costume with the body as movement of the assigned body is detected.
