In the Virtual Reality field, presence refers to the sense of "being there" in the virtual world. Our aim in this work is to evaluate the usefulness of the Emotiv EPOC EEG device to measure the brain activations due to the sense of presence during the navigation in a Virtual Environment (VE), using for the analysis the sLORETA tool. We compare between two experimental conditions: free and automatic navigation through a VE. In this preliminary step, we monitored 9 healthy subjects, obtaining significant differences between the free and automatic navigation conditions in the activity of the right insula for the Theta and Alpha bands. The insula activation is related to stimulus attention and selfawareness processes, directly related with the sense of presence.
在虚拟现实领域，临场感指的是在虚拟世界中“身临其境”的感觉。我们这项工作的目的是评估Emotiv EPOC脑电图设备在测量虚拟环境（VE）导航过程中因临场感而引起的大脑激活方面的有用性，并使用sLORETA工具进行分析。我们比较了两种实验条件：在VE中自由导航和自动导航。在这个初步阶段，我们监测了9名健康受试者，发现右岛叶在θ波和α波频段的活动在自由导航和自动导航条件之间存在显著差异。岛叶激活与刺激注意力和自我意识过程有关，而这些过程与临场感直接相关。
