Abstract: An AR or VR display device. First and third input gratings receive light of a first color from first and second projectors, respectively, coupling the light into a first waveguide. Second and fourth input gratings receive light of a second color from the first and second projectors, respectively, coupling the light into a second waveguide. An output diffractive optical element couples light out of the waveguides towards a viewing position. The first and second projectors provide light to the input diffractive optical elements in directions that are at a first and second angle, respectively, to a waveguide normal vector. The output diffractive optical element couples light out of the waveguides in a first range of angles for light from the first projector and in a second range of angles for light from the second projector, the first range of angles and the second range of angles differing but partially overlapping.

Abstract: Devices, media, and methods are presented for an immersive augmented reality (AR) experience using an eyewear device with spatial audio. The eyewear device has a processor, a memory, an image sensor, and a speaker system. The eyewear device captures image information for an environment surrounding the device and identifies an object location within the same environment. The eyewear device then associates a virtual object with the identified object location. The eyewear device monitors the position of the device with respect to the virtual object and presents audio signals to alert the user that the identified object is in the environment.

Abstract: A method and system for predicting remaining thermal runtime in an electronic device is disclosed. The method involves obtaining the device's current processor power consumption and temperature sensor reading, selecting a predefined function relating temperature and time at that power level, determining the position of the current temperature on the function, calculating the time position for a shutdown temperature, and determining the time difference to estimate remaining runtime. In some examples, the functions are quadratic curves fitted to empirical time-temperature data collected at different processor power levels. In one embodiment, the prediction is implemented in augmented reality glasses and continuously adjusted using updated power and temperature data. The runtime prediction enables the device to warn the user prior to shutdown and perform graceful shutdown procedures.

Abstract: A system, method, and medium for inferring cognitive load of a user of an extended reality (XR) display system. Visual content is presented to a user's eye from a display device.

Abstract: A user interface with a message composition area is presented at a user device. The message composition area includes message content presented in a base size. The user interface further includes a resizing graphical element presented at a base position within the user interface. A resizing gesture commences at the base position. While the resizing gesture is in progress, the resizing gesture is tracked and the message content is dynamically resized as positioning of the resizing gesture changes relative to the base position. Transmission of a message is caused when ending of the resizing gesture is detected at an adjusted position relative to the base position. The message includes the message content in an adjusted size relative to the base size.

Abstract: An XR system is provided that enhances user interaction within extended reality environments through precise hand scale estimation. The XR system is configured to capture tracking data of a user's hand as the user interacts with a mobile device. Concurrently, the XR system captures pose data of itself and uses the tracking data and the pose data to determine a reference line segment. This segment aids in calculating three-dimensional distances between node pairs of the user's hand. By employing these measurements, the XR system effectively calculates a hand scale factor that is used for accurately integrating the user's hands into an XR user interface.

Abstract: A system and method for contextual three-dimensional messaging in augmented reality (AR) environments receives chat messages with specified real-world destinations and stores them associated with those locations. When a user wearing an AR device enters a destination location, the system detects their presence using techniques like GPS, Wi-Fi positioning, or computer vision. It then generates a 3D visual representation of the message and determines an appropriate spatial position within the physical environment based on environmental analysis and object detection. The 3D message is displayed at the determined position in the AR view. The system can analyze message content to identify topics and match them to detected real-world objects for contextual placement. Users can interact with displayed messages through gestures or voice commands to reply, forward, delete, or reposition messages. This enables immersive, location-aware messaging experiences that seamlessly blend digital content with the physical world.

The mobile device determines a bounding box and a geometric center of the bounding box to determine the path to circumnavigate the object. The mobile device determines a height above a ground to assist in navigation.

Abstract: An adaptive calibration method in a brain-computer interface is disclosed. The method is used to reliably associate a neural signal to an object whose attendance by a user elicited that neural signal. A visual stimulus overlaying one or more objects is provided, at least a portion of the visual stimulus having a characteristic modulation. The brain computer interface measures neural response to objects viewed by a user. The neural response to the visual stimulus is correlated to the modulation, the correlation being stronger when attention is concentrated upon the visual stimulus. Weights are applied to the resulting model of neural responses for the user based on the determined correlations. Both neural signal model weighting and displayed object display modulation are adapted so as to improve the certainty of the association of neural signals with the objects that evoked those signals.
