One personal computer to many students in classroom with wireless sensor network technology

In traditional computerized classroom, such as computer laboratory, each kid is equipped with one desktop (or laptop) for learning. This kind of computerized classroom, one kid one desktop, has some disadvantages. For example, the cost of establishing the classroom, like the computer laboratory, is high and the kids are constrained in their seats while having the classroom learning activities. The design concept of this computerized classroom in mine is one computer one kid, which we will argue that is adult-oriented, not kid-oriented. Kids have their requirements in using information technology in classroom. Instead of using monitor, keyboard, and mouse, an alternative way, we think, is allowing kids to input their message via their body motion, such as gesture, which is a much nature way to use the technology in classroom.
