PocketSOMPlayer -
Intuitive Access to Music on mobile devices

The user's demand for the always accessible portable music archive calls for novel ways of access to music. There is a need for new techniques and interfaces, freeing us from burdensome selection of tracks, allowing us to explore music spaces. The PocketSOMPlayer brings music maps, which automatically organize music archives according to acoustic similarity, to mobile devices and thus allows very quick selection of a specific taste of music.


PocketSOM on PDA

The PocketSOMPlayer supports both selecting music from the device itself and/or streaming of music over wireless networks such as WLAN, GPRS or UMTS. Thus, the streaming mode provides direct access to huge central music repositories from wherever there is a wireless network connection

Drawing paths/trajectories on the music map On the PocketSOMPlayer paths/trajectories are conveniently drawn using a pen on the touch-screen. Drawing a trajectory creates a play-list, which is instantly shown on the next screen.
