Abstract

This dataset contains electroencephalographic (EEG) recordings of 24 subjects doing a visual P300 Brain-Computer Interface experiment on PC. The visual P300 is an event-related potential elicited by visual stimulation, peaking 240-600 ms after stimulus onset. The experiment was designed to compare the use of a P300-based brain-computer interface with and without adaptive calibration using Riemannian geometry. EEG data were recorded using 16 electrodes during an experiment at GIPSA-lab, Grenoble, France, in 2013.

Methodology

Subjects participated in sessions with two runs (Non-Adaptive and Adaptive, randomised order). Each run had Training (calibration) and Online phases. In Non-Adaptive mode, Training data calibrated the MDM classifier for Online phase. In Adaptive mode, classifier initialized with generic class geometric means from previous experiment and continuously adapted using Riemannian method. Brain Invaders interface: 36 symbols in 12 groups, one repetition = 12 flashes (2 Target, 10 non-Target). Training phase: 80 Target and 400 non-Target flashes (fixed). Online phase: variable repetitions based on performance to destroy targets. Subjects blind to mode of operation.
