Abstract: An apparatus, system, and method for a waveguide system may be used to support eye tracking in a head mounted display (HMD). The waveguide system may be positioned in a user's field of view and within a lens assembly of the HMD to capture light that is reflected from an eye. The waveguide system may have a number of multi-directional gratings configured to direct light to an out-coupling grating. The multi-directional gratings include first and second in-coupling diffraction gratings disposed in a waveguide. The first and second in-coupling diffraction gratings are oriented to direct incident light in multiple directions within the waveguide towards the out-coupling diffraction grating.

Abstract: In one aspect, the systems and methods may automatically trigger ranging include a device which may establish a connection between a first device comprising a first ultra-wideband (UWB) antenna and a second device having a second UWB antenna. The device may receive from one or more motion sensors of the first device, motion data of the first device during an inactive ranging phase. The device may determine to switch from the inactive ranging phase to an active ranging phase responsive to the motion data indicating motion of the first device satisfying a threshold criteria. The device may perform a first ranging operation between the first device and the second device using the first UWB antenna of the first device and the second UWB antenna of the second device, responsive to switching from the inactive ranging phase to the active ranging phase.

Abstract: An apparatus, system, and method for an imaging system that compensates for chromatic aberration. The imaging system may include a metalens that provides image light to a camera module. The camera module may include an optical splitter and a number of image sensors. The optical splitter separates the image light into a number of color components. The optical splitter directs the number of color components to individual image sensors. Processing logic may adjust image data for each of the color components to compensate for chromatic aberration. Processing logic may form a single chromatic aberration corrected image by recombining the adjusted image data from each of the color components.

Abstract: A method for providing a relightable avatar of a subject to a virtual reality application is provided. The method includes retrieving multiple images including multiple views of a subject and generating an expression-dependent texture map and a view-dependent texture map for the subject, based on the images. The method also includes generating, based on the expression-dependent texture map and the view-dependent texture map, a view of the subject illuminated by a light source selected from an environment in an immersive reality application, and providing the view of the subject to an immersive reality application running in a client device. A non-transitory, computer-readable medium storing instructions and a system that executes the instructions to perform the above method are also provided.

Abstract: A computer-implemented method for determining if a player has reached a certain level of gameplay-performance while playing a game within a virtual reality, VR, environment. The player wears a headset having a display for viewing the VR environment and an object tracking system. The headset's object tracking system is capable of tracking movement of a portion of the player in 3-D space to establish an actual-response path by the player during gameplay. The method includes calculating, at a first time, an ideal-response path of gameplay for the tracked portion of the player in 3-D space. The ideal-response path is the path that will achieve the certain level of gameplay performance. The method then compares, at a second time, the actual-response path with the calculated ideal-response path, and finally indicates, in response to a match in the comparing step, that the play has reached a certain level of gameplay performance.

Abstract: A method for motion-tolerant optical heart-rate monitoring may include calibrating an array of heart rate sensors of a handheld device by (i) evaluating, while the handheld device is being held by a user, an output of each sensor in the sensor array, (ii) selecting, based on the evaluation of the output of each sensor, a subset of sensors in the sensor array for use in detecting a heart rate of a user, and (iii) using the subset of sensors to monitor the heart rate of the user. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: In one embodiment, a method includes establishing a video call between a plurality of client systems, wherein access to an assistant system is persistently maintained during the video call, receiving, from a first client system of the plurality of client systems, a request by a first user to be performed by the assistant system during the video call, wherein the request references one or more activities associated with one or more users associated with the plurality of client systems, analyzing, by a context engine of the assistant system, images of a scene of the video call to identify the one or more activities within the scene, instructing the assistant system to execute the request based on the identified one or more activities, and sending, to one or more of the plurality of client systems, a response to the request while maintaining the video call between the plurality of client systems.

Abstract: A head-mounted device may include a frame, a display coupled to the frame, a front head-engaging structure coupled to the frame, a retention mechanism configured to secure the front head-engaging structure to the head of the user, and one or more non-contact sensor(s) disposed on one or more of the frame, the display, the retention mechanism, and/or the front head-engaging structure. The non-contact sensor(s) may be configured to detect a measurement of the head of the user. In some examples, the measurement may include a head circumference, a size and/or shape of the head. In some examples, the head-mounted device may dynamically adjust a length of the retention mechanism based in part on the sensor data received from the one or more non-contact sensor(s).

Abstract: A necklace manager of an interactive necklace can sense user conditions and transmit messages to recipient computing devices. The necklace manager can compare sensed user conditions from the interactive necklace sensors to predefined user condition templates to determine a match. The matching predefined user condition template can be mapped to a user intent. The necklace manager can, in response to mapping the sensed user conditions to the user intent, transmit a message to a recipient device that is based on the mapped user intent and a user identifier. In some implementations, the recipient device can be an other interactive necklace that performs a mapped interactive necklace action in response to the received message. For example, a wearer of the recipient interactive necklace can perceive sentiments, emotions, and/or reactions from a user wearing the originating interactive necklace by perceiving interactive necklace actions triggered by the received message.
