Movement tracking is represented in this window by a sphere contained in a cube. The program creating this image I wrote in C++ using OpenGL. The cube is a representation of the relative detentions of the transmitter's range. The sphere's position corresponds to the position of the tracker attached to the user's wrist. Below the sphere is a display of its coordinate position in a range from A to Z. The location reads into a web address in this form:

     (X,Y,Z)
<--- C, N, N
     www.cnn.com 
        

In this way the participant can visually witness the formation of the website address as they move.
