Once we had the library working with Processing, we needed to visualize four variables for each sensor:
- The position on the scalp
- The quality of the signal
(functions alraedy present in the EPOC control panel)
- The strength of the signal
- The change of strength over time
Working with Giulia Marzin we visualized each sensor with a polar graph that shows the strength of the signal using lines and a color indicator for its quality.
