**Experimental Control System**
===== Goggles Input =====
Input to the goggles is controlled by the NTIVideoSwitcher software, located in the 'Programs' folder under the 'Start' menu. It is helpful to add this program to your start menu.

Figure 1

As shown in Figure 1, to show the input from the XP computer in the goggles, click on the Goggles/Proj row in column #2 (column #2 is the XP computer input). It is also a good idea to connect the 4 output (labelled "None" in the figure) to the same computer because that is also used for goggle connections.
