Hardware used

The EEG device used in the experiment is the Emotiv Epoc X 14 channel headset

Experiment

During the Covid-19 lockdown, we invited several students with varying levels of education (High school, Middle school, Undergraduate) to watch an online lecture and we recorded their EEG data and brain waves during the lecture. We began by asking them several questions to understand their knowledge base and picked several videos that they would be able to understand and several videos that they wouldn't be able to understand. We then recorded their EEG data, Brain waves, and added a binary variable that indicated whether the student understood the lecture or not. (1 = Understood the lecture | 0 = Did not understand the lecture). We compiled all of our recordings and appended them to a single dataset (EEG data.csv). We also recorded various details relating to the students and videos used, they can be found in Subject details.csv and Video details.csv

Column content in EEG_data.csv

• The first column (A) contains a variable that indicates the video used during the experiment. The videos can be found in Video_details.csv.
• The second column (B) contains a variable that indicates who watched the video. More details pertaining to the student can be found in Subject_details.csv.
• Columns 3-16 (C - P) contains raw EEG data from the 14 sensors.
• Columns 17-86 (Q - CH) contains 5 Brain waves for each sensor.
• Column 87 (CI) contains the binary variable that indicates whether the subject understood the lecture or not.
