The development of dynamic, shape-changing interfaces as a method of human-computer interaction is receiving increasing attention in both research and manufacturing. The present focus is mainly on hardware development, rather than potential applications. To advance this area, considering temporality in shape-changing displays and interfaces is vital in understanding how to design applications for (and with) such devices. Prototypes within the field range from those which actuate changes at high speed, to the deliberately slow, with a complex range of temporal movement in between. Current research highlights the importance of temporal form in interaction design, and expressive movement, but this is yet to be applied in detail to shape-change. This paper examines the current state of play for temporality in shape-changing interfaces, examines the role of time and design in existing prototypes, and proposes an adaptive methodology for design utilising time, space and shape based on previous research.
