Abstract
Techniques are provided for alerting a user of a virtual reality (VR) system of hazards in the proximate environment. An example method of proximity sensing with a virtual reality headset includes communicating with a station via a first wireless link, detecting a target object using radio frequency sensing on a second wireless link, determining a rate of approach associated with the target object, and generating an alert based at least in part on the rate of approach.
Claims71
A method of proximity sensing with a virtual reality headset, comprising:
- communicating with a station external to the virtual reality headset via a first wireless link that operates in a first frequency band;
- detecting a target object using radio frequency sensing on a second wireless link, wherein the second wireless link operates in a second frequency band that is different from the first frequency band;
- activating at least one camera based at least in part on detecting the target object using the radio frequency sensing on the second wireless link;
- determining a rate of approach associated with the target object;
- and
- generating an alert based at least in part on the rate of approach;
- wherein activating the camera is based on a size of the target object exceeding a threshold size.
