Music is a fundamental part of most cultures. Controlling music playback has commonly been used to demonstrate new interaction techniques and algorithm. In particular, controlling music playback has been used to demonstrate and evaluate gesture recognition algorithms. Previous work, however, used gestures that have been defined based on intuition, the developers' preferences, and the respective algorithm's capabilities. In this paper we propose a refined process for deriving gestures from constant user feedback. Along this process a set of free-hand gestures for controlling music playback is developed. The situational context is analyzed to shape the usage scenario and derive an initial set of necessary functions. In a successive user study the set of functions is validated. Furthermore, proposals for gestures are collected from the participants for each function. Two gesture sets containing static and dynamic gestures are derived and analyzed in a comparative evaluation. The evaluation shows that we developed an appropriate set of free-hand gestures for music playback. Our results indicate that the proposed process, that includes validation of each design decision, improves the final results.
