  • Publication number: 20170251176
    Abstract: A vehicle camera system captures and transmits video to a user device, which includes a viewing device for playback of the captured video, such as virtual reality or augmented reality glasses. A rendering map is generated that indicates which pixels of the video frame (as identified by particular coordinates of the video frame) correspond to which coordinates of a virtual sphere in which a portion of the video frame is rendered for display. When a video frame is received, the rendering map is used to determine the texture values (e.g., colors) for coordinates in the virtual sphere, which is used to generate the display for the user. This technique reduces the rendering time when a user turns his or her head (e.g., while in virtual reality) and so it reduces motion and/or virtual reality sickness induced by the rendering lag.

  • Publication number: 20170251181
    Abstract: In embodiments of immersive interactive telepresence, a system includes a vehicle that captures an experience of an environment in which the vehicle travels, and the experience includes audio and video of the environment. User interactive devices receive the audio and the video of the environment, and each of the user interactive devices represent the experience for one or more users who are remote from the environment. A trajectory planner is implemented to route the vehicle based on obstacle avoidance and user travel intent as the vehicle travels in the environment. The trajectory planner can route the vehicle to achieve a location objective in the environment without explicit direction input from a vehicle operator or from the users of the user interactive devices.

  • Publication number: 20170201722
    Abstract: A tele-immersive environment is described that provides interaction among participants of a tele-immersive session. The environment includes two or more set-ups, each associated with a participant. Each set-up, in turn, includes mirror functionality for presenting a three-dimensional virtual space for viewing by a local participant. The virtual space shows at least some of the participants as if the participants were physically present at a same location and looking into a mirror. The mirror functionality can be implemented as a combination of a semi-transparent mirror and a display device, or just a display device acting alone. According to another feature, the environment may present a virtual object in a manner that allows any of the participants of the tele-immersive session to interact with the virtual object.

  • Patent number: 9613450
    Abstract: Dynamic texture mapping is used to create a photorealistic three dimensional animation of an individual with facial features synchronized with desired speech. Audiovisual data of an individual reading a known script is obtained and stored in an audio library and an image library. The audiovisual data is processed to extract feature vectors used to train a statistical model. An input audio feature vector corresponding to desired speech with which the animation will be synchronized is provided. The statistical model is used to generate a trajectory of visual feature vectors that corresponds to the input audio feature vector. These visual feature vectors are used to identify a matching image sequence from the image library. The resulting sequence of images, concatenated from the image library, provides a photorealistic image sequence with facial features, such as lip movements, synchronized with the desired speech. This image sequence is applied to the three-dimensional model.

  • Publication number: 20170045952
    Abstract: The subject disclosure is directed towards a technology by which dynamic hand gestures are recognized by processing depth data, including in real-time. In an offline stage, a classifier is trained from feature values extracted from frames of depth data that are associated with intended hand gestures. In an online stage, a feature extractor extracts feature values from sensed depth data that corresponds to an unknown hand gesture. These feature values are input to the classifier as a feature vector to receive a recognition result of the unknown hand gesture. The technology may be used in real time, and may be robust to variations in lighting, hand orientation, and the user's gesturing speed and style.

  • Patent number: 9536312
    Abstract: A depth construction module is described that receives depth images provided by two or more depth capture units. Each depth capture unit generates its depth image using a structured light technique, that is, by projecting a pattern onto an object and receiving a captured image in response thereto. The depth construction module then identifies at least one deficient portion in at least one depth image that has been received, which may be attributed to overlapping projected patterns that impinge the object. The depth construction module then uses a multi-view reconstruction technique, such as a plane sweeping technique, to supply depth information for the deficient portion. In another mode, a multi-view reconstruction technique can be used to produce an entire depth scene based on captured images received from the depth capture units, that is, without first identifying deficient portions in the depth images.

  • Patent number: 9529426
    Abstract: Head pose tracking technique embodiments are presented that use a group of sensors configured so as to be disposed on a user's head. This group of sensors includes a depth sensor apparatus used to identify the three dimensional locations of features within a scene, and at least one other type of sensor. Data output by each sensor in the group of sensors is periodically input, and each time the data is input it is used to compute a transformation matrix that when applied to a previously determined head pose location and orientation established when the first sensor data was input identifies a current head pose location and orientation. This transformation matrix is then applied to the previously determined head pose location and orientation to identify a current head pose location and orientation.
