PneUI: Pneumatically Driven Soft Composite Material for Shape-Changing User Interfaces from Tangible Media Group on Vimeo.

Inspired by ocean organisms that morph and move bodies without rigid skeletons, PneUI (p'newee) is an enabling technology to build shape-changing interfaces through pneumatically actuated soft composite materials. The composite materials integrate the capabilities of both input sensing and active shape output. This is enabled by the composites' multilayer structures with different mechanical or electrical properties. The shape-changing states are computationally controllable through pneumatics and predefined structure. The design space of PneUI is explored through four applications: height-changing tangible phicons, a shape-changing mobile device, a transformable tablet case, and a shape-shifting lamp.
