We present two studies to discuss the design, usability analysis, and educational outcome resulting from our system Augmented Body in physiotherapy classroom. We build on prior user-centric design work that investigates existing teaching methods and discuss opportunities for intervention. We present the design and implementation of a hybrid system for physiotherapy education combining an on-body projection based virtual anatomy supplemented by pen-based tablets to create real-time annotations. We conducted a usability evaluation of this system, comparing with projection only and traditional teaching conditions. Finally, we focus on a comparative study to evaluate learning outcome among students in actual classroom settings. Our studies showed increased usage of visual representation techniques in students'11 note taking behavior and statistically significant improvement in some learning aspects. We discuss challenges for designing augmented reality systems for education, including minimizing attention split, addressing text-entry issues, and digital annotations on a moving physical body.
