Tokyo University professor Michitaka Hirose (R) and his team developed a camera-equipped special goggle, which makes cookies bigger to help users' diet at his laboratory in Tokyo on June 2, 2012. Hirose conducted an experiment, asking examinees to eat as many cookies as they want with and without the glasses. The results showed they ate 9.3 percent less on average with the goggle showing cookies 1.5 times bigger than they actually are and ate 15 percent more with cookies looking two-thirds of their real size.
