Polyphony Digital is on verge of introducing an extraordinary new feature for console gaming that could really have a major impact on the racing game genre by adding “Head tracking” system into GT5's feature list using the PlayStation Eye.  
While Head tracking concept is not new since PCs already have used this feature for racing sims for some time now using head tracking glasses, what was really new and special about Polyphony Digital announcement is the why they are using "head tracking" feature using the PlayStation Eye only.  
I think it's maybe hard for some of us to imagine how exactly the head tracking system can be utilized in racing games so I found this video maybe useful in explaining what the head tracking idea is all about and how it could be implemented on racing games and manipulate the “cockpit camera” in a fantastic way.
