Educators Paper

Unlike the One Laptop Per Child concept promoted by the MIT Media Laboratory, this study utilizes a wireless sensor network to support a multiple-student group-learning game with one PC in classroom. In the traditional computerised classroom, each student is equipped with one desktop (or laptop) computer for learning. This approach (one kid one desktop) has some disadvantages. For example, the cost of establishing the classroom is high, and students are confined to their seats during learning activities. It is adult-oriented, not kid-oriented.

This alternative approach, based on a wireless sensor network, allows students to interact with a computer via body motions, such as gestures, which is a much more natural way to use technology in the classroom. A set of ribbons with wireless gesture-detection sensors connects to a server. The ribbons are worn by the students, and the entire classroom's gestures are captured and sent to the server.

With this technology, the classroom can be reconfigured from one kid one desktop to many kids one desktop. In one application, students are asked to create, share, and review stories using the gesture-detection ribbons in the classroom.
