I wonder how well the hardware would work with an input system like Dasher. Dasher was experiment in statistical inference and tries to be an accessibility tool as well. http://www.inference.phy.cam.ac.uk/dasher/ . I found it really fun to play around with and could get decent speeds but not great. It's true about eye tracking being prohibitively high. When we order an eye tracker for the lab, it ended up costing us…

"The way to take over an industry is not to fix the current model, but to completely destroy it and replace it with a model you know is better" Open source is the better model for every single industry. It's coming.
Do you think open source fine art is better than one from a single artist's vision?

#86As someone that suffers from RSI, I'd be interested in an Opti-mouse. Does this exist yet?
(You can see the performance of the eye-tracking warping + mouse at 2:41 of the video: http://youtu.be/7BhqRsIlROA?t=2m41s).

#87I wonder if a version of this for mobile phones could make typing on a phone faster than fumbling with a touch screen.
Mmmm... that was a great deal slower than me using the latest Android swiping support, even counting errors. Can't speak to the other mobile tech stacks, but if you're typing on a phone is slower than that you might want to poke around, you may be missing a technology already installed on it. (Not a criticism of the excellent work here. It's a fundamental bandwidth problem.) Concretely: In the time the demo took to w…
>Microsoft patents eye-tracking keyboard software
The idea’s just like swipe-based keyboard software, but instead of tracking the motion of your fingertip, the system tracks eye movement.
As your glance moves from key to key, darting around and changing direction, a devices camera records its gaze, and with a little algorithm magic, Microsoft tries to work out just which keys you were looking at – and ultimately, what word you were attempting to construct.

#89In the demo, he was quick and he didn't even seem to use much autocompletion. However, I wonder if using a different keyboard layout would be helpful. Dvorak a Colmak, for example, place the more frequently used letters on the home row so you'll spend more time with your eyes there. You can evaluate different layouts with a tool like this: http://patorjk.com/keyboard-layout-analyzer/
For visual search I would disregard keyboards entirely and go alphabetical: A b c d E f g h I j k l m n O p q r s t U v x y z.
The issue being that while I can certainly find the letters when they are alphabetical - clusters of commonly used letters are further apart. Having "th" and "ng" visually close to each other aids a lot.

I wonder if it really matters with your eyes vs. your hands and fingers. Flicking your gaze around the keyboard seems much easier than moving your fingers around - you'll never have two fingers hitting each other. And on the other end of the speed spectrum, it seems like it's unlikely that this will ever quite be as quick as operating even a QWERTY keyboard with fully functional hands.
If we're talking about what's optimized for eyes and the movement of them, you wouldn't even want a keyboard layout, you'd want something more like a dart board or oval shaped dartboard where the spaces are letters and the most common letters are towards the center. QWERTY is fine for someone familiar with it, like an experienced typist whose already mapped those keys mentally, but I expect someone with a lifelong di…
