Abstract
Techniques are described herein that enable advanced gaming and virtual reality control using radar. These techniques enable small motions and displacements to be tracked, even in the millimeter or submillimeter scale, for user control actions even when those actions are optically occluded or obscured.
Claims20
A computer-implemented method for detecting optically occluded user control actions in a gaming or virtual reality environment, the computer-implemented method comprising:
- receiving a radar signal representing a superposition of reflections of two or more points within a radar field provided by a radar-system, at least one of a first or second points of the two or more points being optically occluded, the optical occlusion residing between a radar antenna of the radar system and the first or second point that is optically occluded;
- determining a relative displacement between the first and second points by spatially resolving the first and second points;
- and
- determining a user control action for a gaming or virtual reality application based on the relative displacement between the first and second points or providing the relative displacement between the first and second points effective to enable determination of the user control action even though the at least one of the first or second points are optically occluded.
1 more element
An apparatus comprising:
- one or more computer processors;
- a radar system comprising:
- one or more radar-emitting elements configured to provide a radar field;
- and
- one or more antenna elements configured to receive a radar signal representing a superposition of reflections of two or more points within the radar field provided by the radar system, at one least one of the two or more points optically occluded or visually obscured;
- and
- one or more computer-readable storage media having instructions stored thereon that, responsive to execution by one or more computer processors, implement a plurality of modules including a micromotion tracking module and a control recognition module:
- the micro-motion tracking module configured to determining a relative displacement between a first and second point of the two or more points, at least one of the first or second points associated with a user, the determining by spatially resolving the first and second points;
- and
- the control recognition module configured to determine a user-control action based on the relative displacement between the first and second points, and pass the user-control action to an application effective to enable control of the application.
