  • Patent number: 10055013
    Abstract: Systems and approaches provide for user interfaces that are based on object tracking. For example, the object may be a user's head or face. As the user moves his head or face and/or tilts a computing device, the content displayed on the computing device will adapt to the user's perspective. The content may include three-dimensional (3D) graphical elements projected onto a two-dimensional (2D) plane and/or the graphical elements can be associated with textural shading, shadowing or reflections that change according to user or device motion to give the user the impression that the user is interacting with the graphical elements in 3D environment. A state of motion of the device can be determined and jitter and/or latency corresponding to the rendering of content can be altered so as to minimize or decrease jitter when the device is stationary and/or to decrease or minimize latency when the device is in motion.

  • Patent number: 10027883
    Abstract: Various embodiments enable a primary user to be identified and tracked using stereo association and multiple tracking algorithms. For example, a face detection algorithm can be run on each image captured by a respective camera independently. Stereo association can be performed to match faces between cameras. If the faces are matched and a primary user is determined, a face pair is created and used as the first data point in memory for initializing object tracking. Further, features of a user's face can be extracted and the change in position of these features between images can determine what tracking method will be used for that particular frame.

  • Patent number: 9975483
    Abstract: Approaches are described for utilizing a combination of location determining and tracking techniques to attempt to provide driver assistance under a variety of different circumstances, such as location assistance to locate or get back to a particular object or location, and visual and/or audible assistance to alert a driver of potential danger. For example, a driver assistance system can be provided that can monitor traffic conditions as well as attentiveness of a driver using a portable computing device (such as a mobile phone) to provide visual and/or audible notifications to alert the driver to potential dangers and/or take defensive action. The driver assistance system can further be used to automatically determine the location of a user's parked automobile and provide assistance, such as directions, to get back to the location where the user parked his or her automobile.

  • Patent number: 9866820
    Abstract: An electronic device can have two or more pairs of cameras capable of performing three-dimensional imaging. In order to provide accurate disparity information, these cameras should be sufficiently calibrated. Automatic calibration can be performed by periodically capturing images with a pair of front-facing cameras and locating matching facial or other feature points in corresponding images captured by those cameras. Correspondences can be detected between feature points and the corresponding feature points can be normalized and outlier feature points can be rejected. A transformation matrix can be determined using at least a portion of remaining feature points and can be used to determine rotation and translation parameters to correct for misalignment between the cameras. The calibration parameters can be refined or otherwise adjusted, and can be used or stored for use in correcting images subsequently captured by those cameras.

  • Patent number: 9860517
    Abstract: Various embodiments provide a method for determining conditions associated with the presence of a user in order to perform object detection. For example, various heuristic tests can be used to identify movement within a sequence of images or to identify user engagement therewith and, if movement or user engagement is identified, stereo disparity can be computed in an attempt to detect an object within a predetermined distance of the computing device. Accordingly, if the distance of the object is within the predetermined distance, object detection is performed. If the object is beyond the threshold distance, however, object detection is not performed in order to conserve battery life of the computing device.
