For the record, our eye tracking experience started in the late '80s 
working on Navy and Army contracts for using eye tracking is a variety of 
military applications, including targeting and eye strain minimization. We 
also did a project for NASA involving using eye tracking as a method of 
heads up display cursor control in a space-suit based computer. (How do you 
read your repair manual when you're fixing the outside of your space station?)

Advertising still uses eye trackers regularly (there are useful things you 
can learn) as do new interactive technologies.

The devices themselves are not problematic. It's the interpretation of the 
results that gets people into trouble.
