Notes on the data
Contact quality map
Accurate EEG data collection depends on good sensor contact with the scalp and good EEG signal quality.
The contact quality map shows you a visual representation of the current contact quality at each individual sensor on your headset. Each sensor’s contact quality status can be seen in real time, so you can adjust them (if needed) to achieve 100% contact quality.
The contact quality statuses are:
  • ‌Green - good
  • Orange - moderate
  • Red - poor
  • Black - very poor
Please note: The contact quality map for EPOC Flex will only show the sensors that have been configured.
