Claim:
1. A method of assisting a user wearing a head-mounted display (HMD) in locating a physical handheld controller located on a physical base station, the HMD covering the user's field of vision and having a HMD tracker which provides information regarding the position of the HMD, the method comprising: generating and outputting, by a processor, instructions to the HMD to display on the HMD a virtual world; determining, by the processor, the position of the HMD in the physical world using information from the HMD tracker; generating and outputting, by the processor, instructions to the HMD to display on the HMD a virtual base station, a virtual controller and a virtual hand in the virtual world, the virtual base station and virtual controller in apparent locations corresponding to actual physical locations of the physical base station and physical controller and the virtual hand in an assumed apparent location; determining, by the processor, based upon the position of the HMD, that the user has moved toward the physical base station in the physical world; generating and outputting, by the processor, instructions to the HMD to display on the HMD the virtual base station, virtual controller, and virtual hand, with the virtual hand closer to the virtual base station than the assumed apparent location; determining, by the processor, that the physical controller has been removed from the physical base station; and generating and outputting, by the processor, based upon the determination that the physical controller has been removed from the physical base station, instructions to the HMD to display on the HMD a virtual hand in the virtual world, without displaying the virtual base station or the virtual controller.
