Using ARToolKit for 3D Hand Position Tracking in Mobile Outdoor Environments

Introduction This poster presents how we have used the ARToolKit to develop a cheap and low cost 3DOF (degrees of freedom) hand tracker, allowing us to use a video camera (see figure 2) mounted on the head to track the motion of the hands of the user (see figure 1) as real world X, Y, Z values. This tracker is most useful when working in mobile outdoor environments, as traditional tracking technology (magnetic, ultrasonic, acoustic) is not available. When using mobile computers outdoors, traditional desktop devices such as mice and keyboards do not work well, and so we have developed purely glove based user interfaces based on our ARToolKit hand tracker. i l i l l , ll i i i i i l l , , l . i i l i i il i , i i l i l i , l i , i i il l . i il , i i l i i ll, l l l i l i .
