摘要： A system includes a display panel, a temperature sensor configured to measure a temperature of the display panel, a thermoelectric device coupled to the display panel and configured to transfer heat to or from the display panel, and a controller electrically coupled to the temperature sensor and the thermoelectric device. The controller is configured to receive the measured temperature of the display panel and, based on the measured temperature of the display panel, send a second signal to the thermoelectric device to cause the thermoelectric device to remove a first quantity of heat from the display panel or send a third signal to the thermoelectric device to cause the thermoelectric device to provide a second quantity of heat to the display panel.

摘要： A head-mounted display device for providing images to a wearer includes a focus-supporting light projector and a beam steerer. The focus-supporting light projector is configured to project light for rendering images based at least on virtual reality contents and/or augmented reality contents. The light projected from the focus-supporting light projector corresponds to an image plane that is selected based at least in part on a position of a pupil of an eye of the wearer. The beam steerer is configured to change a path of the light projected from the focus-supporting light projector based on the position of the pupil of the eye of the wearer.

摘要： A method for classifying a gesture made in proximity to a touch interface. A system receives data related to the position and/or movement of hand. The data is delimited by identifying a variable length window of touch frames. The variable length window of touch frames is selected to include touch frames indicative of feature data. The variable length window of touch frames is classified based upon classifications learned by the classifying module to identify gestures.

摘要： A depth camera assembly (DCA) for depth sensing of a local area. The DCA includes a transmitter, a receiver, and a controller. The transmitter illuminates a local area with outgoing light in accordance with emission instructions. The transmitter includes a fine steering element and a coarse steering element. The fine steering element deflects one or more optical beams at a first deflection angle to generate one or more first order deflected scanning beams. The coarse steering element deflects the one or more first order deflected scanning beams at a second deflection angle to generate the outgoing light projected into the local area. The receiver captures one or more images of the local area including portions of the outgoing light reflected from the local area. The controller determines depth information for one or more objects in the local area based in part on the captured one or more images.

摘要： A head mounted display (HMD) includes an electronic display configured to display a virtual scene to a user, an optics block, an eye tracking system, and a varifocal actuation that mechanically changes a distance between the optics block and the electronic display. The varifocal actuation block is configured to change a location of an image plane of the HMD and includes a motor, a power screw coupled to the actuating motor configured to turn responsive to actuation of the motor, and a nut sled on the power screw that is coupled to the electronic display. The nut sled is configured to move back and forth along a length of the power screw responsive to the power screw being turned by the motor that results in movement of the electronic display relative to the optics block.

摘要： An electronic device tracks, for a user performing a target acquisition movement within a 3D space, movement parameters of a plurality of input devices of the user. The electronic device predicts, for the user, a region of interest within the 3D space, based on the movement parameters. The region of interest includes a plurality of targets in close proximity. The electronic device predicts an endpoint of the target acquisition movement, within the region of interest. In some embodiments, the plurality of input devices includes an eye tracking input device, each input device corresponds to a predefined input device type, and the movement parameters include gaze data from the eye tracking input device. In some embodiments, input devices includes an eye tracking input device, a head-mounted display, and a hand-held controller, and the user's eye, hand, and head movements are coordinated.
