I believe haptics is currently a niche application.  It's not in Sir Tim's vision; I just believe this is going to be a future educational tool.  It’s going to integrate with the 3D world tools like second life, etc.  It’s too early to tell how far this technology will evolve into mainstream education.  It will probably start in the gaming world first then find a place in education.  Just my thoughts!  

This idea of Meta tagging your work for the average person is not easy.  I think if you ask the average person what a Meta tag is and what it’s used for, you will probably get a variety of answers.  I believe for Meta tagging to work, they will have to create an incentive for people to tag their own content. Otherwise, what's in it for the individual One possible solution could be, creating intelligent bots that do the work for us.  This technology is already available and will probably be the way it evolves.

Just a prediction
