So, my brother's co-worker's husband has ALS.
This sucks ass.
However, he and his co-worker were brainstorming things that he could do to keep him occupied and not just confined to a wheelchair, even as the disease progresses. My brother was thinking, with the advent of more advanced head tracking and the like, that a computer with some hardware/software would help with the 'I am stuck in a wheelchair and can't do anything' problem, and since I generally know more about computer hardware/software than he does, asked me for help.
I got nuffin.
Is anyone aware of any good consumer-level hardware or software that'd do eye-tracking/gesture stuff? I know TrackIR/FreeTrack is available for head-tracking, but having it do mouse-work and the like would probably take some doing. And I have no idea how I'd be able to make it emulate clicks, and my brother wants this system to be able to be entirely motor-function free, save, well, head gestures for now. Ideally it'd have full eye tracking but I think that's a little unrealistic.
Some cursory googling reveals some other options (mostly just focused on raw communication) but with the breadth of experience this forum has I'm sure someone's been down this road before.
