Mobile users listen to large digital music libraries with thousands of songs. Browsing such libraries in mobile contexts is difficult due to constraints of the context and devices. We explore the usage of physical interaction with digital music to overcome these limitations. Our solution is to utilize the physical orientation of a mobile device as a tool for exploring music. We focus on allowing users to manage their music for easier mobile access. We present a novel bimanual interaction method for mapping items from a music library into different orientations of the mobile device. An experiment was conducted to test our prototype, focusing on efficiency and recall locations of items in the mapping. The interaction method was found to be significantly faster than using a touch screen without the mobile device. Subjectively users valued the bimanual method in ease of use, efficiency, and pleasantness. Categories and Subject Descriptors H.5.2 [Information Interfaces and Presentation]: U...
