Eye-tracking is one of Sony's unnoticed cool game-technology demos

Sony has received a lot of attention for Project Morpheus, its virtual-reality goggles that it unveiled in March. But an equally cool demo that came from the same tech-development lab is eye-tracking, where you can control where you’re aiming in a video game with your eyes. Simply by looking at something, you can pinpoint a reticle on the target without ever touching a game controller.

At this year’s Game Developers Conference and the recent Neuro Gaming event, Sony demonstrated how the eye-tracking works with Infamous: Second Son, a popular open-world superhero game for PlayStation 4, that it had modified for the eye-tracking input system. I played around in a limited environment of the game as Delsin Rowe, the protagonist. When I looked around the game world with my eyes, the camera followed.
