I think this was the technology used in Avatar to get the facial expressions of the actors onto the alien characters. They fitted the actors with facial sensors so they could capture emotional expressions.
I wonder how far we are from being able to record the perfect golf swing and then compare yours to the one on the screen. We all know several people will do whatever they can to improve their ability in the sports arena. I don't think it will be long before the technology allows everyone to hit the ball like Tiger Woods. Now the interesting part for me will be to see if the perfectly trained athelete will be as good as the naturally trained. Can computers and science replace natural ability? Or will science reach it's limits before human nature which can go the extra mile.
I have seen applications where Hollywood would dress an actor in a MEMS suit and use the feedback from it to "vitualize" them for use in CGI; much more lifelike than regular computer animation. I think it has been used for video game design as well.
Yes, this is like a virtual co-pilot. One application I've seen is that pro golfers and ball players are capturing their expert golf or baseball swings. Users can then match their own swings to the experts to see where they are matching for falling short of the expert's swings.
I imagine this technology has been available for some time in the movie industry, what with millions of budget dollars. Glad to see the form and functionality has advanced to be useful to sporting pursuits.
