Chris Harrison has developed a tiny projector that senses your every move called the OmniTouch. It is a wearable multitouch interactive for everywhere. You can read or write an email on the wall, table, your palm, or your pants let. Students would be actively engaged without being at or on a computer. Teachers would be more mobile and be able to grade/access information without being tied to a specific location. However, the biggest positive would hopefully be the reduction of cost for computer equipment. With increasing budget cuts each year, schools need a means to bring technology into the classrooms with minimum costs.
