The kids (and grown-ups) at Waterloo Labs in Austin, Texas have come up with a way for us to play video games with nothing but our eyes.
Blink, look left and look right replace things like press A and push left. Sure, it looks a little janky at first. And also looks slightly useless. But once you get past the idea of it being crafted for stoners or computing students with too much spare time on their hands, you realise that it could actually be a really great way for people with certain disabilities (especially ones affecting their hand or finger control) to enjoy video games.
