Why the study?
Studies on maze and fire escape situations have been hindered by risks and practical constraints, and objective event-related potential data during emergency decision-making remain limited.
Does virtual reality technology elicit measurable event related potentials during an escape test in emergency situations?
Does virtual reality technology elicit measurable event related potentials during an escape test in emergency situations?
Virtual reality can be used to elicit and analyze event related potentials (P300, ERN) in simulated emergency situations, providing objective data for brain-computer interface development.
Significant ERP changes observed in VR escape scenarios; leaves open BCI utility in emergencies pending validation.
The role of electroencephalography (EEG) in the development of brain-computer interface (BCI) technology is increasing. In particular, the importance of the analysis of event related potential (ERP) in various situations is becoming more significant in BCI technology. Studies on past maze and fire situations have been difficult due to risks and realistic problems. Nowadays, according to the development of virtual reality (VR) technology, realistic maze and fire situation can be realized. In this study, ERPs (P300, and evented related negativity) were analyzed to collect objective data on case determination in an emergency situation. In order to overcome the limitations of previous methods that evaluating the EEG frequency change, ERPs were derived by setting epochs for stimulation and standardizing them, and evaluated for ERPs in this study. P3a and P3b, which are subcomponents of P300, were analyzed and the evented related negativity (ERN) was analyzed together with error positivity (Pe). As a result of the study, statistically significant changes of ERPs were observed, this result, which has little related research, is considered to be meaningful as medical basic statistics.
