Abstract

Virtual environments provide a whole new way of viewing and manipulating 3D data. Current technology moves the images out of desktop monitors and into the space immediately surrounding the user. Users can literally put their hands on the virtual objects. Unfortunately techniques for interacting with such environments have yet to mature. Gloves and sensor based trackers are unwieldy, constraining and uncomfortable to use. A natural, more intuitive method of interaction would be to allow the user to grasp objects with their hands and manipulate them as if they were real objects.We are investigating the use of computer vision in implementing a natural interface based on hand gestures. A framework for a gesture recognition system is introduced along with results of experiments in color segmentation, feature extraction and template matching for finger and hand tracking and hand pose recognition. Progress in the implementation of a gesture interface for navigation and object manipulation in virtual environments is discussed.
