    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.
