MusicCube : making digital music tangible

To some extent listening to digital music via storage devices has led to a loss of part of the physical experience associated with earlier media formats such as CDs and LPs. For example, one could consider the role of album covers in music appreciation. Previous efforts at making music interaction more tangible have focused mainly on access issues. A case study is presented in which several content attributes of Mp3 formatted music as well as control access are made more visible and tangible. Play lists, music rhythm, volume, and navigational feedback were communicated via multicolored light displayed in a tangible interface. Users were able to physically interact with music collections via the MusicCube, a wireless cube-like object, using gestures to shuffle music and a rotary dial with a button for song navigation and volume control. Speech and non-speech feedback were given to communicate current mode and song title. The working prototype was compared to an Apple iPod, along the dimensions of trust, engagement, ergonomic and hedonic qualities, and appeal. Subjects rated the MusicCube higher on scales associated with hedonic qualities, while the iPod was preferred for ergonomic qualities. Results on trust measures were found to correlate with ergonomic qualities, while sense of engagement related to hedonic aspects. Subjects generally valued the expressive and tangible interaction with music collections. Next design steps will focus on increasing ergonomic aspects of the MusicCube while maintaining a high hedonic rating
