The Embry Riddle Aeronautical University (ERAU) offers 22 video demonstrations of machine vision laboratory projects. More and updated versions of projects exist under non-disclosure agreements.
Demos include virtual boxing with XBOX 360, control and manipulate projected objects, cyber presence in a collaborative session, interactive virtual book for classroom use, motion detector and classifier based on object morphology and motion patterns, interactive beam bending, a natural interface for desktop navigation by enabling three cursors, and the list goes on!
A good free source for K12 science, engineering, and robotics teachers.
Also, good hints about components of a Tablet and other mobile PC simulated teaching program.
