EZ-access

I thought the students should look at EZ-access as a demonstration that
kiosks using touchscreen technology could be made accessible. They should
still try to come up with an interface of there own that works better.

EZ-access must be patented since it says to contact the Trace Center about
its use in products. However, I expect it was patented largely as a
defensive measure to insure that someone else did not patent it and make it
more difficult to licence at a reasonable cost. Gregg said that someone
patented some of the techniques they had developed for computer access and
he had to go to court and have those patents overturned at his own expense.
I haven't asked him but I expect that the EZ access would be available for
student projects at no cost.

Isn't EZ-access a proprietary, patented technology?
