Tobii and SteelSeries Release Consumer Eye Tracker

Tobii and SteelSeries have released the Sentry, a consumer eye tracker that
you can (finally) buy.

At CES 2011, Tobii demonstrated an arcade cabinet featuring a classic game of
Asteroids that you could play with your eyes. Using infrared cameras and
illuminators, the game system tracked the player’s pupils to determine
exactly where on the screen his or her gaze was focused. Gamers were able to
blow up incoming asteroids just by looking at them. It’s an effortless and
intuitive way to interact with a computer, and it feels like magic.

The eye tracker conrols the cursor with your gaze, effectively eliminating
the middleman. You still push a button (on the keyboard) to denote an action
(a click), but your hands can stay on the keyboard. And since the computer
can tell where your attention is, as opposed to just where the mouse cursor
happens to be, it can much more easily figure out how to intuitively respond
to you, such as by automatically scrolling up when you’ve read to the bottom
of your screen.

By 2013, Tobii was selling development kits of its eye tracking hardware for
$1,000, and it became immediately obvious that the technology was going to
have a huge impact on the gaming industry.
