In this paper, we explore the possibilities of providing miniaturized audio players with gesture control capabilities that are based on wearable objects. We selected thirteen wearable objects and used them as interaction surfaces. We used user-centered design methods to collect interaction gestures suited for play, stop, volume up, volume down, previous song, and next song functions. The characteristics and possibility of these interaction gestures are also discussed.
