Abstract: A head-mounted display (HMD) is provided, including the following: an emitter configured to emit a scanning beam into an interactive environment in which the HMD is disposed, the scanning beam being configured to continuously trace a predefined scan pattern; a detector configured to detect reflections of the scanning beam back to the HMD by each of a plurality of reflectors; a processor configured to, for each reflector, determine a time at which the reflection of the scanning beam by the reflector occurred, wherein the time is used to determine a location or orientation of the HMD in the interactive environment; a display device configured to render a view of a virtual space that is determined based on the determined location or orientation of the HMD.
