虚拟环境（VE）已被用作情绪诱导程序。在这种情况下，有必要有仪器来分析VE暴露期间的情绪状态。为此目的，应评估EEG等客观技术。本研究的目的是利用便携式脑电装置研究基于虚拟现实的消极情绪诱导过程中大脑活动的变化。使用虚拟公园来诱导十名参与者的负面情绪（悲伤）。研究人员比较了两个时刻（情绪诱导前后）受试者大脑活动的变化。所获得的结果是根据以前的科学文献额叶脑电图不对称，这支持使用便携式脑电图作为一个可靠的仪器来测量情绪VE的可能性。
Virtual Environments (VEs) have been used as mood induction procedures. In this context, it is necessary to have instruments to analyze the emotional state during VE exposure. Objective techniques such as EEG should be evaluated for this purpose. The aim in this work was to study the changes in the brain activity with a portable EEG device during a negative mood induction based on a VE. A virtual park was used to induce a negative mood (sadness) in ten participants. Changes in the brain activity of subjects were compared between two moments (before and after emotional induction). Obtained results were in accordance with previous scientific literature regarding frontal EEG asymmetry, which supports the possibility of using the portable EEG as a reliable instrument to measure emotions in VE.
