Gaze Gaming Tech Promises Faster Eye-Controlled Interaction
NewScientist is reporting that further research is progressing on new types of user input devices. Specifically, "gaze gaming," a technology that promises faster interaction using only your eyes. Currently technology for sight-based interaction is far too slow for practical applications in things like gaming. "Eye-gaze systems bounce infrared light from LEDs at the bottom of a computer monitor and track a person's eye movements using stereo infrared cameras. This setup can calculate where on a screen the user is looking with an accuracy of about 5 mm."
There is going to have to be a very accurate system of "disabling tracking". I mean, take the FPS example. How often am I going to be spinning around when I glance down for a quick ammo count?
Or, if you look up to check your HP/MP in an MMO, will you be randomly changing targets, or worse, disengaging them to move?
Its an interesting idea, definitely useful for somethings, but it shouldn't ever take the place of a mechanical pointing device like a mouse or trackball.
If sharing a song makes you a pirate, what do I have to share to be a ninja?
This seems like a good idea in theory, but in reality we rarely keep our eyes fixed on any point with all that much precision. Our eyes are always shifting around to get a bigger picture of things most of the time, even when we're trying to hold a steady gaze on something. Trying to precisely control a game, or anything else, with one's eyes seems to me like much more trouble than it's worth.

Imagine this:
When you focus on something, more info about it slowly appears.
Either it becomes more detailed then the suroundings, or details like health, stamina, or whatever.
It could be quite impressive.
I steal signatures. This one used to be yours.
Imagine using this feature to render highly detailed 3D images only where the user is actually looking. The peripheral vision is almost useless, the actual area that does most of the seeing is in the center of the retina. The brain fills in the blanks and keeps a mental image of what you are seeing that gets updated through rpid eye movement. With a smart setup this could be translated in a huge screen that appears to have a large resolution in every direction while keeping the processing power requirements still accessible. The mouse is a great interface, I don't see any reason to replace that just yet.
