Modular Line-based Shape Changing UIs

Ken Nakagaki, Artem Dementyev, Sean Follmer, Joseph A. Paradiso and Hiroshi Ishii


We present ChainFORM: a linear, modular, actuated hardware system as a novel type of shape changing interface. Using rich sensing and actuation capability, this modular hardware system allows users to construct and customize a wide range of interactive applications. Modules are equipped with rich input and output capability: touch detection on multiple surfaces, angular detection, visual output, and motor actuation. Each module includes a servo motor wrapped with a flexible circuit board with an embedded microcontroller.

Leveraging the modular functionality, we introduce novel interaction capability with shape changing interfaces, such as rearranging the shape/configuration and attaching to passive objects and bodies. This project intends to expand the design space for interaction with actuated curve interface in LineFORM using advanced hardware design.
