No calibrated points were achieved. :o(
I’ll look into LC tech’s eye gaze device.
Thank you!

You could also try LC technologies' Eye Gaze device.
Sorry if this has been mentioned already....but on the Tobii I series device, Were there any points on the calibration screen that he was able to get? What I mean by this is....When he calibrated to red and you're looking at the points on the screen that he was able to get how many were there? And in what areas of the screen were they? Top row? Middle? If he was only able to calibrate in a certain area did you try resizing the calibration area to just those points? If you do this then you can try going to calibration again. More often than not those who only get a red calibration can get up to yellow or green by resizing the calibration area in my past experience.

The older eyemax models from Dyanovx and the PRC devices show an actual picture of the clients eyes, (to my knowledge, and I have been meaning to ask a tobii rep) the I series do not.
Using the actual picture I was able to tell that the “glint” was reflecting of a clients eyeglass frames, not their actual eyes… (This led to an epic use of masking tape over the eyeglasses that did nothing to dispel my growing reputation as a geek J) But we were ultimately able to then train on the accent and Dynavox…
So I would also consider trial of a different device, if your ocular motor eval shows the client being able to track etc, then you “should” be able to get a device working…

Jeremy,
I didn’t think about the lens coating! I recommended an eye exam to provide an updated reading and see if there are new ocular issues.
did trial with one eye with no success. I tried the TOBII I-15. Other suggestions?
Thanks

Hi Kelli
Although bi-focals are obviously a really big issue fro eyegaze systems, actually, anti-reflective coatings on the lenses can be an even bigger problem. And I would also like to agree with observation that all the eyegaze systems have slightly different performances and it may be a case of trying him with a range of systems. I also notice that you haven’t listed single eye sensing as one of the options you have tried.

Hi Kelli,
I am also wondering which eye gaze device you tried as there is quite a bit of variability in the eye gaze control devices.
I have known VA to pay for laser eye correction treatment in an effort to remove the need for bifocals... Perhaps that would be an option, however you stated that you could not get him to calibrate even without the bifocals.
Like Antoinette, I wonder if you were able to calibrate to use the device?
Finally, there are many medications which affect pupil dilation that also may interfere with calibration.

Greetings and happy Monday. I know this AT forum is typically focused on our PALS but I’d like your perspective regarding this challenging patient.
I have a veteran with C1-C4 complete Quadriplegia using a tongue switch to independently operate his Permobil 300. He has a Blom Trach speaking valve system in place although his average utterance length varies from 0 to 5 or 6 words. Many attempts have been made by his first speech pathologist and resp therapist to change his vent settings and increase his utterance length. He has tried to use a head mouse without success due to limited head ROM. I had him in clinic today to calibrate him for eye gaze – no success. Even with changing the positioning of his bifocals, taking his glasses off, changing the color of the background and dot, changing the size of the calibration dot, and adjusting the lights in the room – no avail.
I’m hesitant to recommend a tongue switch for access to a communication device since he is also using his tongue to operate his Permobil chair (he is in the chair approx. 10-11 hours per day) and he is eating some foods and liquids by mouth. What other access methods could be considered for this patient?
Thank you so much. I truly value your insight!
