MobileSOM

Mobile Selection Of Music is a project that is all about creating and designing innovative user interfaces on mobile devices for browsing music collections. MobileSOM is an application developed in J2ME giving the user the look and feel about new concepts and possibilities to consume music on mobile devices.
The basic idea is to display a music collection on a map rather than in a file browser. Songs with similar characteristics are grouped together on units which are displayed by CD covers or metaphoric symbols (for example a guitar may be associated with rock music) that describe the underlying pieces of music. Those units form a map which is shown in the following screenshots. Moreover, units with similar content can be mapped next to each other with the help of Self-Organising Maps. Among the visualisation techniques for displaying such maps are Islands of Music. An intuitive user interface enables a simple way of selecting music titles from the map and adding them to a playlist. Playlists generated in this manner are played on a mobile device or streamed from a web server. The device can also be used as a remote control, i.e. instead of playing a piece of music, the software triggers another device to play the song.

 

Thesis

The project MobileSOM was designed and implemented by Peter Hlavac. Detailed information can be found in his Thesis Innovative User Interfaces for accessing Music on Mobile Devices. The poster can be downloaded here.

Download

Due to different display formats and resolutions of the mobile devices, there exist several versions of MobileSOM. Here, two versions explicitly tested on the devices listed below are provided.

Installation on a Sony Emulator M600

Download and Install Emulator (PC)

Download MIDlet

Installation on a Nokia 7710

Download MIDlet

Download Content and unpack to memory card on device d:\MobileSOM\ (Requires at least 113MB free space)

Note: The MIDlet is not signed. Any access to local file system has to be confirmed every time! The Application might be used on any Mobile Device that provides a touch screen, CLDC1.1, MIDP2.0 and an implementation of the MMAPI that supports mp3 playback.

Test Device Abilities

The following MIDletsuite includes a MIDlet for testing internet access in requesting response from a user defined URL and a MIDlet that tries to play an included MP3 file.

Xplayer

The Xplayer is a simple applet that waits for remote requests from the MapViewer MIDlet to play songs. User X selects a song on his mobile device and sends a request to this applet. The device then acts like a remote control.
