    Abstract: A system is provided, including: a head-mounted display (HMD), including, a plurality of retroreflectors, and a display device; an emitter/detector unit, 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, and a detector configured to detect reflections of the scanning beam back to the HMD by each of the plurality of retroreflectors; a computing device, including, a processor configured to, for each retroreflector, determine a time at which the reflection occurred, wherein the time is used to determine a location or orientation of the HMD in the interactive environment, the computing device configured to generate a view of a virtual space based on the determined location or orientation of the HMD; wherein the display device of the HMD is configured to render the view of the virtual space.

    Abstract: Methods and systems for using a robot to provide feedback to a user when the user is engaged in a physical activity includes detecting presence of the user in a geo-location. The user is identified and associated with the robot. User activity in the geo-location is monitored and when the robot detects the user is performing an exercise from an exercise routine, the robot is positioned to one or more positions proximate to the user so as to capture image of a posture held by the user while performing the exercise. The captured image is analyzed and feedback provided to the user to allow the user to improve their posture.

    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.
