Abstract: Features described herein generally relate to providing spatiotemporal guidance within a 360-degree video. Particularly, while a 360-degree video is being displayed to a user, a current location of the view of the user within the 360-degree video is determined. Additionally, regions of interest may be identified within the 360-degree video, along with their location and a time in which the regions of interest are active within the 360-degree video. A visual guide is then overlaid onto the 360-degree video that indicates a current location of the view of the user, as well as locations of one or more regions of interest, as well as the time during which each region of interest is active (able to be viewed) within the 360-degree video. By viewing the visual guide, the user may be able to anticipate a location and timing of regions of interest within the 360-degree video and adjust their gaze to the correct location at the correct time to view such regions of interest.

Abstract: A system for controlling notification outputs at a head-wearable device that is in communication with one or more peripherals. The system is configured to receive a request to provide a notification, and in response to receiving the request to provide the notification: in accordance with a determination that the head wearable device and one of the one or more peripheral devices are in a first state based on first data from one or more sensors of the system, presenting a notification in a first manner that corresponds to the request to provide the notification, and in accordance with a determination that the head wearable device and one of the one or more peripheral devices are in a second state based on second data from the one or more sensors of the system, presenting a notification in a second manner that corresponds to the request to provide the notification.

Abstract: A non-transitory, computer-readable storage medium includes instructions to be executed at an extended-reality (XR) headset is described herein. The instructions cause the XR headset to present, via the XR headset worn by a first user, a three-dimensional volumetric representation of an area of space within an XR application that was selected to be collaboratively edited by the first user and a second user. The three-dimensional volumetric representation of the area of space is viewable by the second user. The instructions further cause the XR headset to receive an indication that the second user has provided an input to add an XR object to the area of space. The instructions further cause the XR headset to, in response to receiving the indication, update the three-dimensional volumetric representation to include the area of space with the XR object.

Abstract: Systems and methods are provided for power beaming that increase power density at the target location by exploiting scattering from terrain. The disclosed systems and methods further provide a variable focus feature allowing the beam power to be concentrated at specified standoff distances from the transmitter and increase the radio frequency (RF) power handling of the receiver using an overvoltage protection circuit in the DC load.

Abstract: The disclosed computer-implemented method may include (1) identifying a trigger element within a field of view presented by a display element of an artificial reality device, (2) determining a position of the trigger element within the field of view, (3) selecting a position within the field of view for a virtual widget based on the position of the trigger element, and (4) presenting the virtual widget at the selected position via the display element. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: A method of saccade-based positioning of a radial user interface includes performing operations while a first radial user interface is displayed on a display. The operations include (a) detecting a saccade movement based on eye-tracking data received from an eye-tracking system; (b) determining whether the saccade movement crosses a first region border corresponding to a first region of the first radial user interface; (c) determining a velocity of the saccade movement based on the eye-tracking data; and (d) dynamically determining a location for a subsequent radial user interface in response to the velocity and in response to determining that the saccade movement crosses the first region border. The method also includes displaying, on the display, the subsequent radial user interface at the location.

Abstract: In one embodiment, a system includes an automatic speech recognition (ASR) module, a natural-language understanding (NLU) module, a dialog manager, one or more agents, an arbitrator, a delivery system, one or more processors, and a non-transitory memory coupled to the processors comprising instructions executable by the processors, the processors operable when executing the instructions to receive a user input, process the user input using the ASR module, the NLU module, the dialog manager, one or more of the agents, the arbitrator, and the delivery system, and provide a response to the user input.

Abstract: Various embodiments of the present disclosure provide an antenna system including a first set of receive antenna elements and a second set of transmit antenna elements. Each receive antenna element is paired with one of the transmit elements. Paired receive and transmit antenna elements point in the same azimuthal direction, and the receive antenna element feeds its paired transmit antenna element. Each receive antenna element and each transmit antenna element has a phase center, and the phase centers of the receive and transmit antenna elements are all positioned substantially along the same axis. The receive and transmit elements are arranged in a phase-conjugate configuration such that, for each pair of receive and transmit antenna elements, those receive and transmit antenna elements are altitudinally spaced substantially the same distance from a plane through the antenna system.

Abstract: A phased array antenna system includes an RF front end, a radome, and an optical calibrator embedded in the radome for enabling in-situ calibration of the RF front end. The optical calibrator employs an optical timing signal generator (OTSG), a Variable Optical Amplitude and Delay Generator array (VOADGA) for receiving the modulated optical output signal and generating a plurality of VOADGA timing signals, and an optical timing signal distributor (OTSD). The in-situ optical calibrator allows for reduced calibration time and makes it feasible to perform calibration whenever necessary.
