My understanding of modern eye tracking systems is that they rely on seeing where the eye is pointing - probably much more reliable than the mechanism we were using which was looking at the electrical signals to try and work out where the eyes were pointing. I have a vague memory that you used to have to train the system as everyone's electrical signals were slightly different.Assistive technology is very much user OneSwitch's jam.
Eye-tracking is a pretty well-accepted technology now. It's built into recent cellphone cameras, so they can have a pointer that (depending on light conditions) will pretty much track your eyes. Tobii is probably the market leader. Their eye-tracking augmented communication tablets are eek! expensive, but so is all assistive technology. Tobii's kit for gamers has brought the cost of the tech down to within reach of experimenters. Maybe the project you worked on at Marconi wasn't directly related, but the concept is a sound one
