Hand Tracking using Spatial Gesture Modeling as Visual Feedback

The ability to accurately track hand movement provides new opportunities for human computer interaction (HCI). Many of today’s commercial hand tracking devices based on gloves can be cumbersome and expensive. An approach that avoids these problems is to use computer vision to capture hand motion. In this paper, we present a complete real-time hand tracking and 3-D modeling system based on a single camera. In our system, we extract feature points from a palm down left hand image and to control a virtual hand model with 2-D global motion and 3-D local motion. The on screen model gives the user instant feedback on the estimated position of the hand. This visual feedback allows a user to compensate for the
