We have been studying a wide range of creativity-centered media to ensure that systems truly support creative and intelligent human activities. Specifically, for over ten years we have developed many 3D sketch systems that support the design of 3D objects. However, their long-term evaluation has revealed that they are not used by designers in real fields. Even worse, they are treated as if they were just mere attractions in an amusement park. The fundamental problem is the lack of the indispensable function for 3D space. In this study, we propose new design principles, “life-sized and operable”, which make the 3D sketch system truly valuable for the designer. The new 3D sketch system is designed on the basis of “Life-sized and Operable”, developed, and evaluated successfully.
