What if your smart watch went all the way around? Facet is an exploration into a wraparound watch: six touch-sensitive segments allowing new interactions.

Abstract: We present Facet, a multi-display wrist worn system consisting of multiple independent touch-sensitive segments joined into a bracelet. Facet automatically determines the pose of the system as a whole and of each segment individually. It further supports multi-segment touch, yielding a rich set of touch input techniques. Our work builds on these two primitives to allow the user to control how applications use segments alone and in coordination. Applications can expand to use more segments, collapses to encompass fewer, and be swapped with other segments. We also explore how Facet concepts could apply to other devices in this design space.
