Hybrid Approach of Augmented Classroom Environment with Digital Pens and Personal Handhelds

We have been developing a system AirTransNote, a computermediated learning system that employs digital pen to realize papercentric augmented classroom. Although the approach was sophisticated, it restricted feedback effects which potentially improve learning. To maximize the feedback effects of the system, we present a hybrid approach of augmented classroom environment. We classified the type of feedback loops in terms of the hybrid approach and improved the system to accomplish the functions by adding (1) note browsing interface for handheld, (2) worksheet editor for teachers, (3) handwriting character recognition engine for versatile use, and (4) HTTP embedded server function for flexible reference of collective results and notes. We also conducted a feasibility study and investigated the effectiveness of the immediate feedback under the hybrid approach.
