During a regular day while on the move, most people interact with multiple portable devices: a personal music player, mobile phone, and digital camera. People driving cars in addition may also use navigation systems. Whereas each of these devices are getting more and more sophisticated, and packed with numerous functionalities, they are each optimized for specific usages. Modern mobile phones for example, claim to function as digital cameras and music players, but these are features that are more often than not added on almost as an afterthought, and are not integrated with the connectivity that the mobile phone represents. From an engineering point of view, the goal of this project is to push mass-market mobile phones to their limits in networked musical exchange by implementing The Compass. Specifically, we are targeting phones embedded with WiFi, music player and location1 capabilities. The idea was to build a true convergence application that integrated localization, mobile networking, and music listening.
