Abstract
Range finding methods and apparatus that may be implemented by VR/MR systems that include a head-mounted display (HMD) and an accessory that the user holds or wears. Range finding sensors (e.g., ultrasonic transducers) may be included on the HMD and on the accessory and used to track distances to and relative position of walls, objects, and other obstacles within constrained physical environments such as rooms, gyms, yards, or fields, or in unconstrained physical environments. Range finding information from the sensors on the HMD and accessory can be used to generate a 3D map of the user's environment that can be used for various purposes in the VR/MR system. In addition to mapping the user's environment, the range finding methods and apparatus may also be used to track the relative position of the accessory with respect to the HMD.
