Exoskin : pneumatically augmenting inelastic materials for texture changing interfaces

Programmable materials have the power to bring to life inert materials in the world around us. Exoskin, provides a way to embed a multitude of static, rigid materials into actuatable, elastic membranes, allowing the new semi-rigid composites to sense, react, and compute. In this thesis, we give an overview of our motivations, design space, and molding architecture that together answer the when, where, and how of Exoskin's use. We then use Exowheel, an automotive steering wheel, as a case study illustrating the concrete benefits and uses of texture change as a multi-modal, bi-directional interface. By incorporating Exoskin, Exowheel is able to transform its surface dynamically to create a customized grip for each individual user, on-the-fly, as well as to adapt the grip during the drive, as the car moves from congested city driving to rougher rural roads. Finally, we introduce the idea of membrane-backed rigid materials as a broader, more versatile platform for introducing texture change and sensing into a variety of other products as well. By deeply embedding soft materials with more-static materials, we can break down the divide between rigid and soft, and animate and inanimate, providing inspiration for Human-Computer Interaction researchers to design more interfaces using physical materials around them, rather than just relying on intangible pixels and their limitations.
