Tagged handles: merging discrete and continuous manual control

Discrete and continuous modes of manual control are fundamentally different: buttons select or change state, while handles persistently modulate an analog parameter. User interfaces for many electronically aided tasks afford only one of these modes when both are needed. We describe an integration of two kinds of physical interfaces (tagged objects and force feedback) that enables seamless execution of such multimodal tasks while applying the benefits of physicality; and demonstrate application scenarios with conceptual and engineering prototypes. Our emphasis is on sharing insights gained in a design case study, including expert user reactions. Keywords Discrete, continuous, haptic, force feedback, tagged object, tangible, tool, token, container, design process.
