Designing Intelligent Systems The Mood Agenda
2
A system that uses music to prepare you for certain activities.
3
The Mood Agenda Creates a more active mood when the user has an upcoming activity. Gives the user an indication of the time he or she has left, until the activity starts.
4
The Mood Agenda Music BPM Pitch Volume User Heartbeat Blood preassure Brain activities
5
The intelligent system Input: Heartbeat Output: BPM
6
The intelligent system Music affects different people on a different way. People listen to different musical styles and they have individual music libraries.
7
The intelligent system Example Moment of relaxationMoment of activity
8
The intelligent system Example Stable relaxationIncreasing active moodActivity 1 hour before the activity 2 hours before the activity
9
Part 1: stable relaxation Uses random start bmp (Bs) Uses a pre defined optimal heartbeat state (Ho) Play random songs from the library with similar bpm’s (max Δ 5bpm) If heartbeat input (Hi) moves towards Ho, the song will rank +1, else -1. If Hi (endsong) – Ho < Hi (beginsong) – Ho Rank + 1 Else Rank - 1 After all numbers have been ranked, the system will only play the songs with an +1 rank and rank them again.
10
Part 2: Increasing active mood Uses the optimal found bpm from part 1 as start bpm (in this example 40). Uses a pre defined optimal heartbeat (Ho) Uses a start bpm increase configuration. Works in an hour time

Part 2: Increasing active mood Song 1 Song 2 Song 3 A Song 1 Song 2 Song 3 B Song 1 Song 2 Song 3 C Song 1 Song 2 Song 3 D 6065 70 75 80 Ho 40 +i60 +i+j 80 +i+j+k 100 +i+j+k+l 120 +i+j+k+l+m Bpm Song are chosen randomly: Song 1 with a similar bpm of the start of the stage Song 2 with a similar bpm of the start bpm+ end bpm 2 Song 3 with a similar bpm of the end of the stage
12
Part 2: Increase active mood Example for stage A If Hi(end stage) – Hi(begin stage) = 15 i= 0 Save song combinations + try new random combination next time ElseDon’t save + try a new random song combination next time Song 1 Song 2 Song 3 A Song 1 Song 2 Song 3 B Song 1 Song 2 Song 3 C Song 1 Song 2 Song 3 D 6065 70 75 80 Ho 40 +i60 +i+j 80 +i+j+k 100 +i+j+k+l 120 +i+j+k+l+m Bpm

Part 2: Increase active mood Song 1 Song 2 Song 3 A Song 1 Song 2 Song 3 B Song 1 Song 2 Song 3 C Song 1 Song 2 Song 3 D 6065 70 75 80 Ho If Δhi < 0 i=i+1 40 +i60 +i+j 80 +i+j+k 100 +i+j+k+l 120 +i+j+k+l+m Bpm
