Until now, we have revealed that shadow media system that transforms shadow that is inseparable from human body can support generation of body expression. In this research, for using this system for expression activity in a group of about 20 in education, we developed new system that can set and transport easily and support space of field flexibly. This system can enlarge projection range three times for acquisition device that obtain three formed images continuously and three projection devices that set up two projectors projecting shadow image to screen and floor. Furthermore, auto calibration can set this system speedy. As a result, we confirmed that this system can use in education.
