Tobii is horrible for people with disabilities. Their reps are driven by making money, their devices dry your eyes out because of the amount of IR they put on your eye balls. And they don't offer extended support. And forget trying to run these devices if you have glasses or any eye condition!
Sad to hear, I demoed a system with a Tobii sensor and it performed very well (even with my glasses). We were wondering about the effect of the constant IR blasts (are they continuous or pulsing?), thanks for the input.
Bring a old cell phone that's sensitive to IR light and place it in front of a tobii system. You'll see they're pulsing at a high frequency something like 30 lights at a >60 refresh rate per second, to the point you can actually see the light on the users face (using sensitive camera). Not all eye tracking companies put this much light on your eye's, but Tobii seems to be cutting corners - to make up for short coming in image processing. It's a brute force method to eye tracking.
The sensation you get after running a tobii is feeling like you've been up past midnight staring at a bright screen. Most people don't get that it's the eye tracker that makes you feel this way. Some of the other more respected companies take the amount of IR light placed on your eye balls seriously and try to drastically reduce it.
Talk to Tobii about it and they'll just bury it and say "there are no none health risks, or regulations about having that much IR light on your eye". Basically no one has set a threshold for how much IR light should be on a person's eye thus it isn't a problem "we should worry about".
It's a bluetooth device that allows controlling the mouse cursor with body movement (head or finger etc) It's cheaper. Coupled with a free dwell clicking software, should work!
2. Eye tracker - there are a lot of options, visit reddit.com/r/eyetracking that and reddit.com/r/ALS and ask them for advice. These devices let you control a PC with your eyes are especially designed for people who have ALS. The ones that work really well cost money, but most insurance companies cover them in full. Avoid Tobii, they are not reliable and are more marketing than anything. Mygaze,LC Technologies, Eyetech digital, smi vision. These are all companies you can trust. All should offer free trail periods and should have a rep who can come and visit your dad to do an evaluation. If they don't offer at minimum 2 week trail, they're not a trusted company. Secondly you can contact your local cities AT clinic they have donated equipment for situations like this.
I actually build chromium from source for this exact reason, I've gotten it to stop phoning home. It phones home for the following:
1. If you are using the Google APIs (see this picture http://i.imgur.com/UodLpFh.png) for the browser to have more functionality.
2. If you have the "Google account Badge" thingy in the upper right enabled.
I don't know exactly what in those two causes the phone home, I assume (educated guess here) that it's verifying your api keys for browser features such as spell check, that or getting the "Badge" thing setup. While you may be opening a new tab labeled blank that "badge" thing is a pure js/html page thats loaded in the background that does need to phone home.
Pyramid Raider, Winner of the 2013 Eyegaze Eye Tracking Application of the Year Award is the first of its kind. Using both an eye tracker in conjunction with EEG technology the player navigates the maze using only their eyes. The experience is adapted to the players mental state. The more stressed the player becomes the harder the maze is to navigate.
