    摘要: A tabletop display providing multiple views to users is described. In an embodiment the display comprises a rotatable view-angle restrictive filter and a display system. The display system displays a sequence of images synchronized with the rotation of the filter to provide multiple views according to viewing angle. These multiple views provide a user with a 3D display or with personalized content which is not visible to a user at a sufficiently different viewing angle. In some embodiments, the display comprises a diffuser layer on which the sequence of images are displayed. In further embodiments, the diffuser is switchable between a diffuse state when images are displayed and a transparent state when imaging beyond the surface can be performed. The device may form part of a tabletop comprising with a touch-sensitive surface. Detected touch events and images captured through the surface may be used to modify the images being displayed.

    摘要: Techniques for user-interaction in augmented reality are described. In one example, a direct user-interaction method comprises displaying a 3D augmented reality environment having a virtual object and a real first and second object controlled by a user, tracking the position of the objects in 3D using camera images, displaying the virtual object on the first object from the user's viewpoint, and enabling interaction between the second object and the virtual object when the first and second objects are touching. In another example, an augmented reality system comprises a display device that shows an augmented reality environment having a virtual object and a real user's hand, a depth camera that captures depth images of the hand, and a processor. The processor receives the images, tracks the hand pose in six degrees-of-freedom, and enables interaction between the hand and the virtual object.

    摘要: Speckle sensing for motion tracking is described, for example, to track a user's finger or head in an environment to control a graphical user interface, to track a hand-held device, to track digits of a hand for gesture-based control, and to track 3D motion of other objects or parts of objects in a real-world environment. In various examples a stream of images of a speckle pattern from at least one coherent light source illuminating the object, or which is generated by a light source at the object to be tracked, is used to compute an estimate of 3D position of the object. In various examples the estimate is transformed using information about position and/or orientation of the object from another source. In various examples the other source is a time of flight system, a structured light system, a stereo system, a sensor at the object, or other sources.

    摘要: Three-dimensional user interaction is described. In one example, a virtual environment having virtual objects and a virtual representation of a user's hand with digits formed from jointed portions is generated, a point on each digit of the user's hand is tracked, and the virtual representation's digits controlled to correspond to those of the user. An algorithm is used to calculate positions for the jointed portions, and the physical forces acting between the virtual representation and objects are simulated. In another example, an interactive computer graphics system comprises a processor that generates the virtual environment, a display device that displays the virtual objects, and a camera that capture images of the user's hand. The processor uses the images to track the user's digits, computes the algorithm, and controls the display device to update the virtual objects on the display device by simulating the physical forces.

    摘要: Generating computer models of 3D objects is described. In one example, depth images of an object captured by a substantially static depth camera are used to generate the model, which is stored in a memory device in a three-dimensional volume. Portions of the depth image determined to relate to the background are removed to leave a foreground depth image. The position and orientation of the object in the foreground depth image is tracked by comparison to a preceding depth image, and the foreground depth image is integrated into the volume by using the position and orientation to determine where to add data derived from the foreground depth image into the volume. In examples, the object is hand-rotated by a user before the depth camera. Hands that occlude the object are integrated out of the model as they do not move in sync with the object due to re-gripping.

    摘要: A system that can enable establishment of a self-describing data network is provided. Generally, the innovation provides a mechanism by which self-describing data can be collected, validated and stored in such a way that permits each data element to be inherently self-describing. The manner in which the data is stored can be analogized to a ‘data chemistry’ whereby data is stored in the smallest meaningful bit (e.g., atom) coupled with descriptive metadata (e.g., tags). In a specific example, the data network maintains health-related data where each element includes a core data element wrapped with descriptive metadata. The descriptive metadata (e.g., tags) can be employed to interrelate the data elements for storage as well as to facilitate efficient traversal of the data network as a whole.
