[simpits-tech] Head tracking

[Marv De Beque]

The next step in head mounted LCD displays is selective virtual reality 
over the viewing area.

This has been tried for things like surgery where the surgeon can see 
both the patient and a VR image painted on sections of his field of view.

For us, you would program an area in 3-D space that you do not want the 
virtual world to be painted (the inside of your cockpit).  As you gaze 
out, any area that you can see that lies inside the cockpit would be 
left clear, that is, no image would be presented to the LCD and you 
would be able to see through the LCD glass.  Areas outside the cockpit 
boundary would be replaced with the VR image in the LCD.  So, as your 
gaze crosses the boundary you will see part of the LCD fill with the VR 
image and the rest would be transparent so you can see and operate your 
controls.

A computer is needed to provide the image switching function by 
recognizing the area that is inside your cockpit and that which is 
outside your cockpit.  A small visor mounted camera is used by the 
computer to tell where you are facing and how much of the image is to be 
kept and what is to be painted as VR.
