FlexCaseProof of concept project from Media Interaction Lab re-invents smartphone flipcase to provide additional interface features:
FlexCase is a novel flip cover for smartphones,which brings flexible input and output capabilities to existing mobile phones. It combines an e-paper display with a pressure- and bend-sensitive input sensor to
augment the capabilities of a phone. Due to the form factor, FlexCase can be easily transformed into several different configurations, or each with different interaction possibilities. We can exhaust FlexCase to perform a variety of touch,pressure, grip and bend gestures in a natural manner, and much like interacting with a sheet of paper. The secondary e-paper display can act as a mechanism for providing user feedback and persisting content from the main display. In this paper,we explore the wealthy design space of FlexCase and present a number of different interaction techniques. Beyond, we highlight how touch and flex sensing can be combined to support a novel type of gestures, or which we call Grip & Bend. We also describe the underlying technology and gesture sensing algorithms. Numerous applications apply the interaction techniques in real-world examples,including enhanced e-paper reading and interaction, a novel copy-and-paste metaphor, or tall degree of freedom 3D and 2D manipulation,and the ability to transfer content and support input between displays in a natural and flexible manner.
