    Abstract: Single-touch immersion control of head-mounted display (HMD) systems is described. One method outputs video from an electronic device to a HMD system that includes a display layer and a variable-transparency layer. The electronic device controls the variable-transparency layer to operate in a first state in which the variable-transparency layer is transparent and to operate in a second state in which the variable-transparency layer is opaque. The electronic device switches between the second state and the first state in response to a single-touch event detected by the electronic device.

    Abstract: Disclosed herein are techniques and systems for inter-device bearing estimation. Particularly, sensor fusion techniques are disclosed that combine motion data of a local computing device with beamforming data of the local computing device to determine a line-of-site path between the local computing device and a remote computing device. A motion sensor(s) of a local computing device may generate motion data from movement of the local computing device. The local computing device may further determine a direction, relative to the local computing device, of a beampattern in which an antenna(s) of the local computing device radiates energy, the beampattern direction being along a communication path between the local computing device and a remote computing device. The local device may then determine, based at least in part on the motion data and the direction of the beampattern, whether the communication path corresponds to a line-of-sight path between the local and remote devices.

    Abstract: A head-mounted wearable device (HMWD) incorporates a visual indicator device (VID) that provides a visual cue to a wearer about activity of the HMWD. The VID may be positioned in a frame of the HMWD to be within an upper portion of a wearer's field of view during wear. The VID may provide a diffuse illumination that is visible to the wearer but does not obtrusively illuminate the face of the wearer, resulting in the visual indicator being unobtrusive to bystanders. Activation, intensity, color, blink rate, or other characteristics of the visual indicator may be used to provide the wearer with information. For example, the VID may illuminate with a solid color while a microphone on the HMWD is active, or blink while the microphone is muted. Input from an ambient light sensor may be used to adjust the operation of the VID during operation.
