Portable electroencephalography (EEG) reliably measures emotions during virtual environment (VE) experiences. This study used EEG to track brain activity changes during a virtual park-induced sadness, confirming its potential for objective emotional assessment in VEs.

Area of Science:

  • Neuroscience
  • Human-Computer Interaction
  • Psychology

Background:

  • Virtual Environments (VEs) are utilized for mood induction.
  • Objective methods are needed to assess emotional states during VE exposure.
  • Electroencephalography (EEG) is a potential objective technique for emotional analysis.

Purpose of the Study:

  • To investigate brain activity changes using a portable EEG device during a negative mood induction within a VE.
  • To evaluate the reliability of portable EEG for measuring emotions in VEs.

Main Methods:

  • A virtual park VE was employed to induce a negative mood (sadness).
  • Brain activity was measured using a portable EEG device in ten participants.
  • EEG data was compared before and after the emotional induction procedure.

Main Results:

  • Observed changes in brain activity aligned with established findings in scientific literature.
  • Frontal EEG asymmetry patterns were consistent with previous research on emotional states.
  • The results support the efficacy of portable EEG in detecting emotional responses.

Conclusions:

  • Portable EEG devices show promise as reliable instruments for measuring emotions in Virtual Environments.
  • Objective assessment of emotional states during VE experiences is feasible with portable EEG.
  • Further research can explore broader applications of this technology in affective computing and virtual reality.
