ok .. but do they have a plug-in for a stylus? (-:
also, i just learned about leap motion off of a technologyreview link.
imagine using one of these things to teach .. provided that:
- the motion detection covers an entire blackboard,
- chalk script scales accordingly to a laptop screen,
- there were some way to "shift up" something you already "wrote" and use the newly available space to write more.
it could also work really well for long-distance collaboration, too ..
