Why GSR? (or "Aren't there better sensors for this purpose?")
- GSR sensor is relatively easy and cheap to design and develop.
- Results reflect autonomic responses which are not easily controlled by a performer.
- During project development, GSR sensor was easy to integrate with microprocessor and general workflow.
- System can take input streams from other sensors (EKG, EEG, audio)
- Currently two separate data streams can be mapped to two separate parameters (cell selection, dynamics)
