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.

Abstract: Disclosed are systems and techniques for performing mapping using radio frequency (RF) sensing. For instance, a server can obtain a first set of RF sensing data and orientation data corresponding to a first wireless device from a plurality of wireless devices. The first set of RF sensing data can be associated with at least one received waveform that is a reflection of a transmitted waveform from a first reflector. Based on the first set of RF sensing data, orientation data, and location data corresponding to the first wireless device, an indoor map can be generated that includes a reference to the reflector.

Abstract: System and techniques are described herein for providing variable rate touch sampling for touch sensors. In one illustrative example, a method of monitoring activity of a person includes obtaining one or more images of a user performing a first movement during a usage instance of an extended reality (XR) device; obtaining first biometric information of the user from at least one first biometric sensor of the XR device while the user performs the first movement; determining fatigue information of the user at least in part based on the one or more images and the first biometric information of the user; and determining an action based on the fatigue information.

Abstract: Techniques are provided for reducing signaling latency in multi-link devices (MLDs). An example method of providing latency sensitive information with a MLD includes receiving downlink data packets from a station via a first radio link, performing radio frequency sensing with a second radio link, detecting a latency sensitive event, and transmitting an indication of the latency sensitive event.

Abstract: Disclosed are systems and techniques for detecting user presence, user motion, and for performing facial authentication. For instance, a wireless device can receive a waveform that is a reflection of a transmitted radio frequency (RF) waveform. Based on RF sensing data associated with the received waveform, the wireless device can determine a presence of a user. In response to determining the presence of the user, the wireless device can initiate facial authentication of the user.

Abstract: Embodiments described herein address these and other issues by providing radio frequency (RF) sensing to determine the status of a driver or other occupant of the vehicle. RF sensing may be provided by existing radios of a vehicle, such a Wi-Fi transceiver, and may therefore provide RF sensing functionality to a vehicle with little added cost. RF sensing can be leveraged to implement safety features such as detecting an unattended child or pet in a vehicle, detecting driver alertness, and the like.

Abstract: Disclosed are techniques for wireless sensing. In an aspect, a user equipment (UE) detects an object and a direction to the object in an environment of the UE, determines whether the object is a human, identifies, based on the object being the human, a sensitive body part of the human, and performs, based on identification of the sensitive body part, a maximum power exposure (MPE) mitigation operation.
