New gadget is available for iPhone to allow camera to follow you automatically when moving around the room.
I will be surprised is similar automatic system wasn't yet invented for HD video camera.
Suppose that I could attach blinking LED to my helmet, turn on video camera lrft on the beach bank ( or in the car for safety
and go sailing. Camera then will concentrate on my movements on the water so I could later precisely watch my own video.
So maybe there is already such gadget at reasonable cost available somewhere but longer distance and waterproof ?
