We propose and explore actuating a smartwatch face to ena-ble extended interactions. Five face movements are defined: rotation, hinging, translation, rising, and orbiting. These movements are incorporated into interaction techniques to address limitations of a fixed watch face. A 20-person study uses concept videos of a passive low fidelity prototype to confirm the usefulness of the actuated interaction techniques. A second 20-person study uses 3D rendered animations to access social acceptability and perceived comfort for differ-ent actuation dynamics and usage contexts. Finally, we pre-sent Cito, a high-fidelity proof-of-concept hardware proto-type that investigates technical challenges.
