openGL window
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:
<--- C, N, N 
In this way the participant can visually witness the formation of the website address as they move.
