Attending the Tokyo Game Show is like hunting for treasure without a map. Invariably, somewhere on the show floor is a hidden gem that makes the whole trip really special, and for TGS 2013 that diamond in the rough was Food Practice Shooter.
Abbreviated to FPS (get it?), Food Practice Shooter is the brainchild of assistant professor Dr. Takayuki Kosaka of the Kanagawa Institute of Technology. The idea is fairly simple, though its execution is a bit more convoluted: In order to obtain more ammo in-game, the player must eat healthy foods in real life.
The system has three high-sensitivity scales that measure the weight of three cups of vegetables. When prompted by the game, the player removes some food from the required cup, which slightly lessens the load on the scale, which in turn communicates to the game which type of food has been taken. Then, a head-mounted sensor measures the movement of your cheek, telling the game whether you've eaten your veggies like a good boy/girl.
There's probably a less obtuse way to encourage healthy eating habits in today's youth, but where's the fun in that? Strap this thing to your face and shoot this zombie tomato or no dessert.
