Architecture For Controlling A Computer Using Hand Gestures
First Claim
1. A system that facilitates a user interface, comprising:
- a tracking component that detects at least one of a plurality of objects within a scene and tracks the respective object, detection of the object based at least in part upon image comparison of a plurality of images relative to a course mapping of the images;
a seeding component that iteratively seeds the tracking component with object hypotheses based upon the presence of the object and the image comparison; and
a filtering component that selectively removes the tracked object from the object hypotheses and/or at least one object hypothesis from the set of object hypotheses, the tracked object removed based at least in part upon a region-based approach in determining depth to cursors and move windows.

Abstract
Architecture for implementing a perceptual user interface. The architecture comprises alternative modalities for controlling computer application programs and manipulating on-screen objects through hand gestures or a combination of hand gestures and verbal commands. The perceptual user interface system includes a tracking component that detects object characteristics of at least one of a plurality of objects within a scene, and tracks the respective object. Detection of object characteristics is based at least in part upon image comparison of a plurality of images relative to a course mapping of the images. A seeding component iteratively seeds the tracking component with object hypotheses based upon the presence of the object characteristics and the image comparison. A filtering component selectively removes the tracked object from the object hypotheses and/or at least one object hypothesis from the set of object hypotheses based upon predetermined removal criteria.
