Eye Tracking

Source: Popular Science

All of that head gear to the right is little bit of tech-wizardry import called a HeadCam. Developed in Germany the HeadCam has many possible applications, but how does it work?

There are four cameras built into the HeadCam, two of which are responsible for tracking your eye movements in 3D by following your retinas. Another camera uses that information to provide a zoomed in view of whatever your eyes are currently looking at and the final camera moves in whichever way your eyes move.

Utilizing this technology has practical benefits, such as studying the eyes in general. More advanced possible uses could be for surgeons, or other similar fields, to use the HeadCam as a teaching tool.

What does this technology mean for film?

You may recall the Robert Zemeckis movies such as The Polar Express, Beowulf and most recently A Christmas Carol. All of these films have used a version of the HeadCam to make the eye movements of the animated characters in an attempt to render them as realistic as possible.

While it is not perfect it is technology that has some serious potential both in movies and practically.
