    摘要： Augmented reality with direct user interaction is described. In one example, an augmented reality system comprises a user-interaction region, a camera that captures images of an object in the user-interaction region, and a partially transparent display device which combines a virtual environment with a view of the user-interaction region, so that both are visible at the same time to a user. A processor receives the images, tracks the object's movement, calculates a corresponding movement within the virtual environment, and updates the virtual environment based on the corresponding movement. In another example, a method of direct interaction in an augmented reality system comprises generating a virtual representation of the object having the corresponding movement, and updating the virtual environment so that the virtual representation interacts with virtual objects in the virtual environment. From the user's perspective, the object directly interacts with the virtual objects.

    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： 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： Three-dimensional environment reconstruction is described. In an example, a 3D model of a real-world environment is generated in a 3D volume made up of voxels stored on a memory device. The model is built from data describing a camera location and orientation, and a depth image with pixels indicating a distance from the camera to a point in the environment. A separate execution thread is assigned to each voxel in a plane of the volume. Each thread uses the camera location and orientation to determine a corresponding depth image location for its associated voxel, determines a factor relating to the distance between the associated voxel and the point in the environment at the corresponding location, and updates a stored value at the associated voxel using the factor. Each thread iterates through an equivalent voxel in the remaining planes of the volume, repeating the process to update the stored value.

    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.
