Abstract: An optical scanner includes a cantilevered optical member protruding from the base portion and a transducer assembly comprising one or more piezoelectric actuators coupled to the cantilevered optical member and configured to induce motion of the cantilevered optical member in a scan pattern. In some cases, the cantilevered optical member has a tapered shape with a distal end narrower than a proximal end adjacent to the base portion of the optical scanner. In some cases, the cantilevered optical member has an elongated width along a first plane and includes a plurality of waveguides. The transducer assembly is configured to induce motion of the cantilevered optical member in a second plane orthogonal to the first plane.

Abstract: A system for subvocalized speech recognition includes a plurality of sensors, a controller and a processor. The sensors are coupled to a near-eye display (NED) and configured to capture non-audible and subvocalized commands provided by a user wearing the NED. The controller interfaced with the plurality of sensors is configured to combine data acquired by each of the plurality of sensors. The processor coupled to the controller is configured to extract one or more features from the combined data, compare the one or more extracted features with a pre-determined set of commands, and determine a command of the user based on the comparison.

Abstract: A control for a virtual reality (VR) system environment includes a portion and an additional portion each configured to contact different portions of a user's body. As one of the portions of the user's body moves towards the other potion of the user's body, the corresponding portion of the material contacting the moving portion of the user's body also moves towards the other portion of the material contacting the other portion of the user's body. Different positions of the portion and the additional portion relative to each other may correspond to different instructions that cause the VR system environment to perform different actions. In some embodiments, the control includes one or more feedback mechanisms providing the user with tactile feedback that simulates interactions with one or more virtual objects presented by the VR system environment.

Abstract: A wearable eye tracking system includes a pair of looping coils in a Helmholtz configuration and an additional looping coil. In one configuration, areas enclosed by the pair of looping coils in the Helmholtz configuration are in parallel with each other, while an area enclosed by the additional looping coil is offset from (i.e., not parallel with) the areas enclosed by the pair of looping coils. In this configuration, the pair of looping coils generates uniform magnetic fields between the two areas of the pair of looping coils in a first direction orthogonal to the areas of the pair of looping coils, and the additional looping coil generates additional non-uniform (or divergent) magnetic fields in a second direction transversal to the first direction.

Abstract: A head-mounted display (HMD) device includes a plurality of deformation sensors attached to a liner formed around a periphery of a HMD, adopted for direct or indirect contact a user's face. The deformation sensors measure deformations of the liner caused by movement of an upper portion of a user's face when the user is wearing the HMD. The deformation sensors are strain gauges embedded in or otherwise coupled to the liner of the HMD. The sensors translate muscle movements of the upper face of the user to changes in the bending strain and radius of curvature on the surface of the strain gauges. The HMD includes a module that reconstructs and projects a facial animation model of the user based on signals from the deformation sensors while the HMD is in use by the user.

Abstract: A head-mounted display (HMD) device includes a plurality of deformation sensors attached to a liner formed around a periphery of a HIVID, adopted for direct or indirect contact a user's face. The deformation sensors measure deformations of the liner caused by movement of an upper portion of a user's face when the user is wearing the HIVID. The deformation sensors are strain gauges embedded in or otherwise coupled to the liner of the HIVID.
