Gaze Gaming Tech Promises Faster Eye-Controlled Interaction 141

Posted by ScuttleMonkey
from the i've-got-my-eye-on-you dept.
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."

        Well I work on these kinds of systems, and that 5mm is not a limitation of the system, it's a limitation of the eyes.

        The fovea (dense area of rods and cones) in the retina is large enough to give you approximately a 1 deg cone of "focus". Which means depending on the distance, you can focus on an area of a given size on the screen. So even with a perfect eye tracker, you cannot pinpoint gaze location exactly just by measuring eye orientation. Accuracy depends on distance from the screen, but 5mm is in the ballpark for what you can achieve (and that is with a perfectly calibrated system, real accuracy will be worse).

          I can't help thinking that using gaze tracking as a primary cursor is (with the exception of physically disabled users who *can't* use a traditional pointing device) somewhat missing the main potential.

          Gaze tracking seems to me to be perfect for a secondary 'information' cursor. Wonder what the date is? Look at the clock on your taskbar and the calendar will pop up. Curious what guild that undead priest over there is in? Simply looking will give you some transparent overlay text detailing guild, current health/mana, and what spell he's casting. Cast your eyes to a person's name on your IM list and it'll tell you when they were last at their computer and what their status message is.

          Another interesting thing I remember reading about was using eye tracking for security. The whole screen is a ramble of random characters, except the precise area of interest being focussed on, which is unscrambled. The viewer's brain assembles what they see into an unscrambled screen, and any onlooker just sees junk.

        I was taking driving lessons together with a friend of me. I was sitting in the backseat when the driving instructor was explaining how it was very important to look ahead, but also that _you will tend to go wherever you are looking_.

        And as if to emphasize the importance of this, our sometimes playful Universe introduced a few seconds later this synchronicity in the form of one of the most stunning blonde girls we have ever seen..

      Have you tried? Sounds like maybe you have not.

      I have. I'm a visual neuroscientist and my research involves accurate measurement of eye position. I also own a relatively high-end SLR camera that senses eye position to control focus (this is not a coincidence). Humans have exquisite control over their eyes. With a good low-latency mechanism to read gaze position, system control (camera, computer, whatever) becomes incredibly quick, efficient, and fluid. The only problem is that you do NOT want the cursor to always track your eye position, you need a switch: sometimes you want the cursor where you are looking, sometimes you want to leave the cursor in place and look around. But this switch is no more than the equivalent of a mouse button, a shift key on a keyboard, or a foot switch. All work, although I prefer the keyboard approach.

    Other than that, and possibly use for the handicapped, I don't see a use for this tech in games/applications. It'll be as reliable and annoying as voice recognition software.

    Simple head tracking would be more useful. Tracking eyeballs fixed on a 2D plane will surely have horrible calibration issues, problems with multiple people looking at the same screen, problems with

      But if you can live with plain head tracking you can use either the commercial TrackIR (http://www.naturalpoint.com/trackir/) or the open source (but win32 only) FreeTrack (http://www.free-track.net/english/). You probably are more interested in something implemented in a head mounted display, but don't see why the same approach can't be used with an HMD, keeping the setup simpler overall. Or perhaps in conjunction with shutter glasses, to get a "window on the 3D world" effect

      Great for shared offices, or public transit, or checking your email in the morning without waking up the roommate.

    I remember the pepsi commercials back in the late 70's/early 80's.
    They tracked where guys were looking and it was not at the product.
    In fact, they frequently didn't remember the product.
    Very popular commercial of a girl exiting the water in a little suit holding a can of pepsi.

  • Why replace the (mouse | right stick) in an FPS? Add this as another input.

    Keep the left stick or WASD keys controlling footwork, and the right stick or mouse controlling the point of view, but add this to allow interacting with some place other than the center of the screen.

    The only problem I see is that, the way it works right now, you can spot a target and move the mouse so the target is at the center of the screen. Once you've got it there you can shoot at it while looking around the periphery of the sc

    Dude, this is exactly how they almost took over the Enterprise that one time when Wesely came home from the Academy on vacation. I wouldn't trust it.
  • Great. Now my beautiful better half doesn't need to try to get me to acknowledge her repeated pleadings for my attention while I game on. Now all she needs to do is put on that top I really like and stand at the edge of my peripheral vision.

    Maybe if I rig a set of blinders...
  • Quickly summarizing a few comments I found interesting from the threads (instead of quoting them all);

    - potential for gaming/military, maybe training sims, bad for desktops
    - third input, as in mouse/gamepad assistance
    - handicapped assistance
    - head tracking benefits
    - potential issues with glasses/contacts
    - 'aiming' accuracy based on size/distance of screen

    And then an additional comment:

    So what if the thing was added to a helmet, with HUD. The fixed (configurable) distance between eye and sensor should increa

    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.

  • John Carmack spoke about this at QuakeCon 2007, not from a controlling in games perspective but rather from an optimization point of view. The eye really only focuses on one point at once; everything else in the field of vision is blurry. His idea was to only make what the eye was looking at on-screen high-detail, thus allowing much more detail in scenes.
  • It's probably not that great on its own for able bodied people, but as one of many inputs it could be quite interesting. It could be used to subtly alter camera views towards what you find interesting, I suppose. This sort of stuff is already in use to generate "heat maps" of where people are looking when using a computer. Like where on a webpage you look [youtube.com], or in game, etc. It'd be useful to know what sort of things people don't care about, or how distracting something fading in / out might be to the task at
