Activity awareness

Activity Awareness

  • Feedback loop between the user and their music.

  • Use the users physiological state to influence the music selection.

  • The music influences the users mood and mindset.

Music and human activity

Music and Human Activity

  • Music has a strong connection with human activity.

  • People like to play music that is appropriate for their current activity.

  • Music will can affect a persons mental state and physical activity.


Music selection

Music Selection

  • Choose the song that the user would most likely like in this state.

  • Use the user prior behavior to learn their preferences.

  • Combine a star rating system with body information.

Results

  • XPod creates a custom context aware playlist.

  • The addition of state information can improve the accuracy of the learning system.

    • Prefrence(Song|Time,Activity) ≠ Preference(Song)

  • Neural Network seems to be best.

    • Generalizes best

    • Over trains very quickly

  • SMO gets the exact.

    • Does not generalize well.


Network structure

Network Structure

  • 289 Input neurons

  • 1 Output neuron

  • 1-50 Hidden neurons

    • 4 is the best


Future work

Future Work

  • Develop a prototype device.

    • Nokia 5500 Sport

    • iPaq and Backpaq

  • Incorporate song metadata

    • Human Generated, eg Last.fm

    • Machine Generated

  • Incorporate other meta information

    • Location Information

    • Recent Phone Calls

    • Weather
