Hi, I'm sceptical as well; if it only relies on the image, would a dark object against a light background stand out as being near you or far away, or this combination in reverse. For this to be more accurate, would it not need ultrasonic distance and imageing to build a 3d surrounding? 2D is fine, but I don't see how it would stop you bumping into things etc, it would make you more on edge as you would have no depth perception. Rant over, we'll just have to wait on Apple coming up with something!! Regards, Mike
