So they talk about 4 ways to use eye tracking, 1) Use gaze to control the camera pivot -- That sounds incredibly annoying. Like I wouldn't be able to just look around a screen without it constantly moving. Though if a system is built with this use case in mind it could be cool. Imagine having a whole 360* view on screen but with it kind of squished around the edges, when you look out to an area on the edge it could immediately foveate the display to that area. 2) Eye contact - Could be really cool. Monsters that can only move when you look away (or blink). Or they disappear if you look directly at them. The NPC's stop talking or get upset if they think that you're not paying attention. 3) natural targeting - I'd like to try this but I'm skeptical. What If I want to look where I'm running for a moment? Then my gun careens across the screen. 4) Immersive Graphics and Sound - This is the most interesting one and it has the worst name. This application dynamically focuses and blurs the depth of field of an image as you look around. One of the big problems with 3D immersive tech right now (Real3D, oculus) is that you can't capture this element of natural vision. They usually default to rendering everything as extremely sharp. I'm surprised they didn't take about typing with your eyes since it's something that eye-tracking is currently used for.
