A multi-touch-recognizer for gesturecards

Abstract

Software engineers and testers have to understand what requirements engineers and UI designers created during early development phases to implement a suitable software system and adequate testing environments. Interaction matters however are often implicitly defined in low-fidelity prototypes without proper specification and documentation. Especially gestures are becoming a powerful interaction channel used with various devices ranging from small mobile phones to large wall-sized displays. Consequently, a need specification and documentation methods arises. Common gesture notations focus on pure textual or graphical approaches, but we argue that hybrid solutions have various advantages, especially in early prototyping phases with cross-functional teams. We present GestureCards, a hybrid gesture notation, and an accompanying gesture recognizer.
