Abstract
A head-mounted display (HMD) is provided, including: an emitter configured to emit a scanning beam into an interactive environment, 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 modulating retroreflectors; a processor configured to, for each detected reflection of the scanning beam, analyze the detected reflection to identify the modulating retroreflector that produced the reflection, and further determine a time at which the reflection occurred, wherein the times at which the reflections occurred and the identification of the modulating retroreflectors that produced the reflections are 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.
