Abstract
When we develop tools and system that include complicated information system, "designing" and "using" need to connect with each other. On this ongoing project, "future black board system" for a junior high class room, we approach "activity based design." It leads to develop good design for users. From beginning of this project until now, we go and research the junior high slass room, then results took in the system. And further, designers need to take part designing curriculum that contains using the system.
