Abstract: In an exemplary technique, audio information responsive to received input is provided. While providing the audio information, one or more conditions for stopping the provision of audio information are detected, and in response, the provision of the audio information is stopped. After stopping the provision of the audio information, if the one or more conditions for stopping the provision of audio information have ceased, then resumed audio information is provided, where the resumed audio information includes a rephrased version of a previously provided segment of the audio information.

Abstract: A mixed reality system including a head-mounted display (HMD) and a base station. Information collected by HMD sensors may be transmitted to the base via a wired or wireless connection. On the base, a rendering engine renders frames including virtual content based in part on the sensor information, and an encoder compresses the frames according to an encoding protocol before sending the frames to the HMD over the connection. Instead of using a previous frame to estimate motion vectors in the encoder, motion vectors from the HMD and the rendering engine are input to the encoder and used in compressing the frame. The motion vectors may be embedded in the data stream along with the encoded frame data and transmitted to the HMD over the connection. If a frame is not received at the HMD, the HMD may synthesize a frame from a previous frame using the motion vectors.

Abstract: A mixed reality system that includes a device and a base station that communicate via a wireless connection The device may include sensors that collect information about the user's environment and about the user. The information collected by the sensors may be transmitted to the base station via the wireless connection. The base station renders frames or slices based at least in part on the sensor information received from the device, encodes the frames or slices, and transmits the compressed frames or slices to the device for decoding and display. The base station may provide more computing power than conventional stand-alone systems, and the wireless connection does not tether the device to the base station as in conventional tethered systems. The system may implement methods and apparatus to maintain a target frame rate through the wireless link and to minimize latency in frame rendering, transmittal, and display.

Abstract: Methods and apparatus for spatial audio navigation that may, for example, be implemented by mobile multipurpose devices. A spatial audio navigation system provides navigational information in audio form to direct users to target locations. The system uses directionality of audio played through a binaural audio device to provide navigational cues to the user. A current location, target location, and map information may be input to pathfinding algorithms to determine a real world path between the user's current location and the target location. The system may then use directional audio played through a headset to guide the user on the path from the current location to the target location. The system may implement one or more of several different spatial audio navigation methods to direct a user when following a path using spatial audio-based cues.

Abstract: One exemplary implementation provides an improved user experience on a device by using physiological data to initiate a user interaction for the user experience based on an identified interest or intention of a user. For example, a sensor may obtain physiological data (e.g., pupil diameter) of a user during a user experience in which content is displayed on a display. The physiological data varies over time during the user experience and a pattern is detected. The detected pattern is used to identify an interest of the user in the content or an intention of the user regarding the content. The user interaction is then initiated based on the identified interest or the identified intention.

Abstract: In one implementation, a method includes: synthesizing an AR/VR content stream by embedding a plurality of glints provided for eye tracking into one or more content frames of the AR/VR content stream; displaying, via the one or more AR/VR displays, the AR/VR content stream to a user of the HMD; obtaining, via the image sensor, light intensity data corresponding to the one or more content frames of the AR/VR content stream that include the plurality of glints, wherein the light intensity data includes a projection of an eye of the user of the HMD having projected thereon the plurality of glints; and determining an orientation of the eye of the user of the HMD based on the light intensity data.

Abstract: In an exemplary technique, speech input including one or more instructions is received. After the speech input has stopped, if it is determined that one or more visual characteristics indicate that further speech input is not expected, a response to the one or more instructions is provided. If it is determined that one or more visual characteristics indicate that further speech input is expected, a response to the one or more instructions is not provided.
