Abstract

Alertness is conjugated to high level of awareness, low level of fatigue, and better mental performance. The level of alertness is related to melatonin level in the blood, which depends on light exposure. The analysis of EEG signal is one of the objective methods of alertness evaluation. Many publications have confirmed the possibility of effective and correct usage of Emotiv EPOC device in EEG signal recording. Emotiv Performance Metrics Detection Suite software registers real time changes in subjective emotions calculated from EEG signal. Two of them – engagement and excitement are associated with alertness. The article presents an attempt to assess the alertness level after exposure to different color of light based on EEG emotion recognition. 50 healthy subjects were recruited. Each subject took part in 3 experiments – each under different light scene (red, blue, white). Altogether 150 experiments with emotions registration (based on EEG) were carried out. The EEG registration was performed before the exposure and just after 40 minutes exposure to the particular light scene. Selected emotions have been used to assess the alertness state. The results of the experiments have been verified statistically. The results showed that the analysis of engagement and excitement changes gives the opportunity to assess alertness.
