 I'm Sean Hollister with The Verge and I'm about to put my eyes into a video game. Sony has a demo at GDC 2014 of eye tracking technology and we're about to calibrate it right now. Let's go ahead. About 60 centimeters away from the screen, all I have to do is look at these two dots and this sensor bar in front of me knows where my eyes are, where I'm looking at. It's a gaze tracking system. And as you'll see in a moment, we'll jump right into a game and I'll be able to look at whatever I want to see. All I have to do is turn my eyes in a direction and it's going to look at whatever I'm aiming at. Right now I'm just going to look for the top of the space needle and it's there. It stops as soon as I get there. It knows that's what I'm looking at and it stops the camera right there. If I want to go back and look at that power beater of the wall again, eyes look for that box. It stops right there. I'm not touching anything. I don't have the controller in front of me. I just look at something and it goes there. So now I'm playing an actual part of the game. I'm just running around this environment. I can throw fireballs. Previously I'd have to use this right analog stick to carefully aim where I want to go. Maybe even I'd have to stop in my tracks if I wanted to be able to accurately aim a fireball. Now fireballs go wherever I'm looking. Now I'm in a combat scenario. I've got some guards here. They've all been patrolling with submachine guns. Normally I'd probably have to stop or maybe enter a bullet time mode and shoot them. But here I can just dance around. I'm just looking at these folks. I can run towards them. Run away from them. Just keep tapping. I'm just shooting wherever I want. Wherever I look. Wherever I think I want to hit something. Out comes a fireball. That's particularly well when I'm running away from a target too, which is something that's completely counterintuitive normally, but something that I guess a superhero would probably be able to do.

 Let's go ahead.
 About 60 centimeters away from the screen, all I have to do is look at these two dots
 and this sensor bar in front of me knows where my eyes are, where I'm looking at.
 It's a gaze tracking system.
 And as you'll see in a moment, we'll jump right into a game and I'll be able to look
 at whatever I want to see.
 All I have to do is turn my eyes in a direction and it's going to look at whatever I'm aiming
 at.
 Right now I'm just going to look for the top of the space needle and it's there.
 It stops as soon as I get there.
 It knows that's what I'm looking at and it stops the camera right there.
 If I want to go back and look at that power beater of the wall again, eyes look for that
 box.
 It stops right there.
 I'm not touching anything.
 I don't have the controller in front of me.
 I just look at something and it goes there.
