  • Patent number: 9766462
    Abstract: Control of head-mounted display (HMD) systems is described. One method displays at least one image on a first display layer of a HMD system. While displaying the at least one image, the method adjust a transparency setting of a second display layer from a first value to a second value to cause the second display layer to be opaque to limit an amount of light that passes through the lens for viewing the at least one image on the first display layer.

  • Patent number: 9609468
    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.

  • Patent number: 9158115
    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.
