Abstract: A virtual reality (VR) headset includes a first camera and a second camera capturing image data of an environment of the VR headset. Each camera has a field of view, and a portion of the fields of view of the first and second cameras overlap while a portion of the fields of view do not overlap.

Abstract: Disclosed herein is a lanyard adjuster that adjusts the length of a lanyard that passes through the lanyard adjuster. The lanyard adjuster includes a housing and a plate residing within the housing. The plate includes flanges that couple with locking slots of the housing to achieve a locked configuration. In the locked configuration, the plate contacts and applies a force on segments of the lanyard that passes through the lanyard adjuster. Therefore, the lengths of the lanyard on either side of the lanyard adjuster are fixed. The plate can be further decoupled from the housing to enable adjustment of the lengths of the lanyard on either side of the lanyard adjuster.

Content is generated based at least in part on the determined location of the VR headset and is provided to the VR headset for presentation.

Abstract: Embodiments relate to crosstalk cancellation to reduce crosstalk vibrations during use of multiple bone conduction transducers. A system, for example, a head-mounted display (HMD) for providing audio to a user, uses vibration sensors to detect vibrations caused by the bone conduction transducers. In particular, a vibration sensor may generate an error signal representing residual vibrations due to crosstalk at a given ear region of the user. The system uses estimated transfer functions for noise propagation paths through the user's head to generate an anti-crosstalk signal. In response to the anti-crosstalk signal, a bone conduction transducer transmits anti-crosstalk vibrations that reduce the error signal at the given ear region.

Abstract: A system maps a user's interaction with a game controller to predefined hand positions that can be used in gaming and multimedia applications. A game controller with sensors receives user input with capacitive sensors and generates sensor outputs. A controller modeling module receives the sensor outputs and trains a model based on the outputs. The trained kinematic model maps the sensor outputs to one or more of a plurality of predefined hand positions. When an application requests the status of a user's hand position, e.g., through an API, the mapped hand position is sent to the application.
