  1. Musicster: A Location-Aware Music Player David Zhao Kevin West

  2. Project Review • What does it do? • Plays different music at different locations • Adjust the speed of the music so it ends when you reach your destination. • What is it good for? • Listen to music between classes • Automatically switch the type of music • Who will care? • Students walking between classes • People want a smart music player

  3. Related Work • Other location-aware applications • Location-Aware To-Do List • Location-Aware Reminder

  4. Demonstration • What will the demo be like? • Show the two different aspects of the project • Selection of playlist based on location (building accuracy) • Alter the speed of music according to velocity of movement • Simulate user moving with Placelab log file • Original Scenario: • Aimed for room-accuracy.

  5. Implementation - Components • Placelab • Gives us coordinates of current location • PocketPlayer • Music player core that decodes and provides basic UI • Plugin architecture to allow DSP/Control modifications

  6. Implementation

  7. Implementation • What is done? • Placelab Analyzer • Playlist selection • Speed adjustment by pitch shift • What is not done? • Frequency independent speed adjustment • Database for locations • UI for creating location entries

  8. Implementation • What issues remain? • Accuracy of Placelab: velocity estimates jump a lot • Better integration of components

  9. Pictures

  10. Evaluation • Criteria: • How accurate is the velocity and location detection • Is there audible difference when the music is sped up? • Will people find this to be useful?

  11. Future Work • Make a nice UI for controlling the system • Using accelerometer or other sensors to detect velocity more accurately • Using other sensors to control music playback
