Visualizing the output

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.
