Doppio: A Reconfigurable Dual-Face Smartwatch for Tangible Interaction
summary
A reconfigurable dual‑face smartwatch prototype is built (paper and instrumented versions) using magnets and capacitive sensing with Android watches, Arduino glue and 3D‑printed cases, yielding a defined interaction space of 124 configurations and a controlled test of over 37 transition types. Results show peeks are very fast and preferred, rotations and detachments are slower but still feasible, and proof‑of‑concept apps (notifications, private viewing, app switching, maps, sharing by detaching the top) work functionally though hardware is thick and battery life is poor.
