At CES, I got to try out Waterloo Labs' eyes-only gaming tech ("electro-oculography"). If you remember, Waterloo Labs previously demoed eyes-only Super Mario Bros. (see below). The tech is actually intended for medical applications–paraplegics, those with amblyopia (“lazy eye”), etc. But as you'll see below, it makes for a very cool gaming peripheral. Unfortunately, Waterloo Labs (and it's parent company, Analog Devices) couldn't obtain the rights to SMB for CES, but I got to try out a DDR clone and a variation on Whack-a-Mole (not shown in video). Enjoy!
