Japan has some pretty high-tech trains, but bumpy rides are still common. If you’re squashed between dozens of commuters and gripping a strap with one hand while holding reading material in the other, turning the page as the speeding carriage lurches to and fro can be downright dangerous.
That’s why NTT DoCoMo has developed a prototype tablet that you can control with your eyes. The “i beam” has a gaze-tracking function that frees your other hand so you can hang on to that subway strap, or, for instance, pull a suitcase around if you’re walking through an airport.
On display at the 2012 Ceatec technology trade show outside of Tokyo, the i beam lets you turn pages with your eyes, scroll through a Web site, or select items like photos in a gallery. A green dot follows your gaze around the screen.
