Description

The zip archive contains EEG data from a newly developed brain-computer interface paradigm. The method is described in [1], and the dataset has been recorded for the application described in [2]. The two folders in the archive contain data from the training (offline) session and from the online session.

Training data: Each subject has two training sessions. The .xdf files were generated by the Lab Streaming Layer (https://github.com/sccn/labstreaminglayer) from EEG data that were recorded using a BioSemi 32 channel amplifier. The files name after (subject_number)_(session_num).xdf. Each file includes 200 trials (50 trials for each direction).

Online data: Each file contains data from one round of the game. The file name pattern is (subject_num)_(repeat_num) _(ramdon_background_num).mat. The Matlab data structure contains the following fields:
data. fsample: sampling rate (512 Hz)
data.trial:  EEG signals for each step
data.time: time series of EEG signals for each step
data.class: classifier output for each step
