Sweet, and by the way, I found about this research study.
People wore belts that vibrated in what ever direction was North. However, many people found that their sense of direction was greatly enhanced, beside a knowing which way was North. They never got lost, and could create highly detailed maps in their head of the area simply by walking around.
How it relates to Trem is, in FPS people often simply associate what places connect to where, which does little in knowing which door to take or which route is fastest. With a simple compass, they could relate which way they are going, and how they got there, with a single point of reference.
When I first started playing Halo, I easily got lost in multiplayer. I soon learned just to look for the nav point that marked the enemy flag. I then found my way around the levels much easier and soon knew the levels like the back of my hand.
Viola, research study, application, and anecdote.
