A collection of things discussed during the SUM workshop in Oslo 1-2 February 2009.

Core of the SUM-project: find features in audio that contribute to the emotional response in listeners.

Biosignals

There are a number of different types of biosignals. The two easiest to record, least invasive, fastest and the most significant:

  • Blood volume pressure (BVP)
  • Galvanic Skin Response (GSR). Measured in siemens (inverse of resistance)


Electronic device

  • Prototype 1: GSR sensor + BVP sensor => Labjack U3
  • Prototype 2: GSR sensor + BVP sensor => CUI (HID)
  • Prototype 3: GSR sensor + BVP sensor + accelerometer => CUI (uOSC)
  • Prototype 4: ?

Challenges:

  • calibration
  • connector - USB, ethernet, wifi, zigbee, bluetooth
  • protocol - MIDI, HID, OSC, SOAP
  • on-board processing?
  • on-body (glove) <=> self-contained device
  • absolute vs. relative data
  • recording: synchronisation => GDIF

Experiments

  • listening 4 types of emotions in music
  • KTH rule system
  • type of music: Mozart sonata
  • record physiological data

Parameters/features:

  • symbolic rules in KTH system
  • Motion
  • Physiological
  • Audio

Emotion validated Sound material:

  • Robert Rowe
  • Lesaffre
  • ISMIR competitions
