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."

  54. I've played Breakout on an eyetracker before... by Anonymous Coward · · Score: 0

    ...so in my case, I've tried.

    It's ridiculously easy to play as long as the ball is moving at a similar speed to the paddle. Once it goes faster it becomes nearly impossible, because every time you look up at the ball to track where it is, you undo your work trying to anticipate the ball's position.

    Also, as a photo geek, I can state pretty emphatically there are plenty of times where you're not looking at the primary subject when you hit the shutter; many times you're waiting for the perfect background moment to match your foreground, or for the idiot gawking at your photography to finally be obscured by something in the background moving in front of them.

    Is it workable? Probably, but the interface isn't as cut-and-dried as a lot of these articles like to claim.

  55. 2mm is a mile in a FPS by GameboyRMH · · Score: 1

    In any FPS gaming situation, you need to be accurate within one pixel, and you need to be lightning fast on top of that. 2mm can make a difference in score equivalent to the difference between a master gamer and a drunk frat boy playing the game using his asscheeks. Case in point: Metroid Prime: Hunters on the DS. When you meet a 4 or 5-star player, your entire understanding of what is humanly possible may change. When you get to the level that can put up a good fight against them you'll definitely understand what I'm talking about.

  56. Not that much by DrYak · · Score: 1

    So 3d engines would have to be substantially reorganized to take advantage of that kind of thing.. If you think at the *game engine* level.
    I was thinking at the OPENGL/drivers level.

    - There exists OpenGL implementations which could get OpenGL command and redistribue it accross several servers on the network, each rendering a part of the diplay.
    - Poorman's Anti-aliasing on the early GeForce / TNT was done by intercepting OpenGL/DX commands and rendering it at a different resolution in a buffer and then subsequently smoothly downsizing the buffer to the screen.
    - Current nVidia drivers produce stereo for games that don't support it, by intercepting the commands and rendering the scene twice, each time offsetted to acknowledge the position of the two virtual eyes of the player.

    I was thinking of something along the same lines.
    Game works as usual, games sends commands to graphic card to render the scene, the modified opengl library intercepts the commands and distributes them to several jobs each rendering a different part of the scene in a buffer using a different resolution. Then those buffers are composited to the screen (the currently looked-at buffer is copied as-is. the lower-res buffer are bilinearily zoomed during copy).
    Of course, this kind of approach works much better with tile-based renderer than with classic graphic cards, because they segment their output in a similare fashion already.

    One advantage is that jobs could be spread accross several GPUs. (Think CrossFire/SLI, but not in Alternate frame rendering mode, but Split screen rendering mode, where some tiles of the split screen aren't rendered using the same resolution as the others)

    *BUT*

    The main problem with that kind of approach, which is also a problem shared with SLI when in Split-screen, is that modern games (such as Crysis) tend to post process a lot of their output, meaning that the software spends a lot of time rendering to buffers different parts of the scene, and only renders to the screen when compositing and applying the filters. (The different kinds of depth- and wholescreen- motion blur, HDR and gloom, etc...) That's one of the reason why games like Crysis are so power hungry and scale badly in SLI beyond two-GPU configuration.

    For those games, I could be easy to do the variable detail in the engine it self (split the scene to several varied-resolution buffers when rendering the main part of the rendering before the compositing), than in the drivers (No point in splitting the scene when drawing the screen because, usually, it's only 2 big triangles used to copy the main buffer to the screen, with a tons of post processing shaders running on them. What should be split is the various buffers before, but it's hard for the drivers to guess which buffers are going to be relevant)

    Or, the game engine will need a new standart to flags which buffer are only some small details, and which buffer are actually the meat of the scene. This sound complicated, but on the other hand will help *A LOT* the organisation and work-unit distribution for SLI.

    *ALSO* ...intel engineer could tell you that this is another argument why ray tracing is better (more easy to split across SLI, more easy to render some part of the scene at a higher resolution and other at lower).
