摘要： A head mounted display (HMD) in a VR system includes sensors for tracking the eyes and face of a user wearing the HMD. The VR system records calibration attributes such as landmarks of the face of the user. Light sources illuminate portions of the user's face covered by the HMD. In conjunction, facial sensors capture facial data. The VR system analyzes the facial data to determine the orientation of planar sections of the illuminated portions of face. The VR system aggregates planar sections of the face and maps the planar sections to landmarks of the face to generate a facial animation of the user, which can also include eye orientation information. The facial animation is represented as a virtual avatar and presented to the user.
A facial tracking system generates a virtual rendering of a portion of a face of a user wearing a head-mounted display (HMD). The facial tracking system illuminates portions of the face inside the HMD. The facial tracking system captures a plurality of facial data of the portion of the face using one or more facial sensors located inside the HMD. A plurality of planar sections of the portion of the face are identified based at least in part on the plurality of facial data. The plurality of planar sections are mapped to one or more landmarks of the face. Facial animation information is generated based at least in part on the mapping, the facial animation information describing a portion of a virtual face corresponding to the portion of the user's face.

摘要： A virtual reality (VR) console receives slow calibration data from an imaging device and fast calibration data from an inertial measurement unit on a virtual reality headset. Using a model of the VR headset, the VR console identifies model locators corresponding to locators on the VR headset and generates estimated positions for locators included in slow calibration data. The VR console adjusts calibration parameters so a relative distance between estimated positions of the locators and positions of their corresponding model locators is less than a threshold value. From the estimated positions, the VR console generates calibrated positions of a reference point on the VR headset associated with images from the slow calibration data. The VR console determines predicted positions of the reference point from the calibrated positions and adjusts calibration parameters so intermediate estimated positions of the reference point are within a threshold distance of the predicted positions.

摘要： A virtual reality (VR) headset includes an electronic display element, an optics block, and an adjustment mechanism. The electronic display element outputs image light. The optics block includes a cone and an additional cone coupled to a lens and an additional lens, respectively. Image light is directed to the lens and to the additional lens via the cone and additional cone, respectively. Each of the cones comprises an opaque material that is deformable to adjust a distance from a base portion of a cone to a top portion of a cone, via, compression, elongation, or both. An adjustment mechanism may receive input from a user and is configured to adjust said distance of one or more of the cone and the additional cone.

摘要： An object is identified or tracked within a volume by projecting a light beam encoded with one or more predefined properties to have a predefined optical structure into the volume. A detector captures light from the predefined optical structure reflected from the volume. By analyzing one or more characteristics of light from the predefined optical structure reflected from the object, the object is segmented from the volume.

摘要： Embodiments relate to a metal frame in a head-mounted display (HMD) that is structured to absorb impact and protect components of the HMD. The metal frame has a wall that is spaced away from a protection shell securing a display panel in the HMD. When the HMD is dropped or subject to external force, the wall may deform but keep the protection shell intact. Moreover, the metal frame has protruding ridges and brackets that surround outward facing cameras on the HMD. If the HMD is dropped, the protruding ridges and brackets can provide protection to the cameras.

摘要： A depth camera assembly (DCA) determines distances between the DCA and objects in a local area within a field of view of the DCA. The DCA includes an illumination source that projects a known spatial pattern modulated with a temporal carrier signal into the local area. An imaging device capture the modulated pattern projected into the local area. The imaging device includes a detector that comprises different pixel groups that are each activated to captured light at different times. Hence, different pixel groups capture different phases of the temporally modulated pattern from the local area. The DCA determines times for light from the illumination source to be reflected and captured by the imaging device from the phases captured by the different pixel groups and also determines distances between the DCA and objects in the local area based on deformation of the spatial pattern captured by the imaging device.
