Abstract

The assessment on the ability of brain-computer interfaces (BCIs) to acquire electroencephalographic (EEG) data in situations of luminous glare is presented. Dazzling is typically a temporary deleterious effect on the ability to see or concentrate due to glare. The potential of BCIs was evaluated by defining a set of strategies involving the illumination process, EEG signal recording and analysis. N-back, a continuous performance task commonly used in cognitive neuroscience was used to test the attention under the effect of dazzling, in parallel with EEG signals acquisition. Statistical data analysis allowed to show the potential of this technique.
