When a participant plays an experiment, the EMOTIV headset they’re wearing collects raw EEG data, performance metrics, and motion data automatically.
Built-in stimuli markers for data analysis in EmotivPRO
All elements in an experiment are time-marked and can be viewed in EmotivPRO. These include:
Start and finish times.
Key presses and mouse clicks. These are recorded and time-stamped in JSON format.
JSON maker files can be merged with EEG Parquet files.
