I recently ran across this article on a Search Engine Optimization site. Many may not know that SEO/SEM peoples are also interested in interface design for the best and easiest way to reach their customers. Bill Slawski of SEO By The Sea found some interesting research papers from Stanford about a point and click interface - except without a mouse. I haven't read through them entirely yet, but somehow the computer senses which part of the screen you're intently staring at and if you hang on it for long enough, your eye will "click" it. It's mostly for people with disabilities at this stage and it might not be too easy to figure out, but it may become the "wave of the future", as some say.
