Abstract:
We propose novel design method to fabricate user interfaces with mechanical metamaterial called Coded Skeleton. The Coded Skele- ton is combination of shape memory alloys (SMA) and 3-D printed bodies, and it has computationally designed structure that is flexible in one deformation mode but is stiff in the other modes. This prop- erty helps to realize materials that automatically deform by a small and lightweight actuator such as SMA. Also it enables to sense user inputs with the resistance value of SMA. In this paper, we propose shape-changing user interfaces by integrating sensors and actuators as Coded Skeleton. The deformation and stiffness of this structure is computationally designed and also controllable. Further, we pro- pose interactions and applications with user interfaces fabricated using our design method.
