Acoustruments: Passive, Acoustically-Driven, Interactive Controls for Handheld Devices

Link to publication page: We introduce Acoustruments: low-cost, passive, and powerless mechanisms, made from plastic, that can bring rich, tangible functionality to handheld devices. Through a structured exploration, we identified an expansive vocabulary of design primitives, providing building blocks for the construction of tangible interfaces utilizing smartphones’ existing audio functionality. By combining design primitives, familiar physical mech
