Also, we humans constantly make tiny involuntary head movements to aurally recalibrate our surroundings. Smyth's use of a head tracker completes the illusion by making sure sounds remain fixed at their intended direction, even (especially) when you move your head.
During my first demo, upon hearing the test tone over my right shoulder I reflexively turned my head towards that direction, and the virtual speaker stayed exactly where it was supposed to image. Without the head tracker, even the best externalization algorithm would have lost the illusion, as the entire soundstage would have moved when I turned my head.
