Abstract

Virtual reality (VR) is an immersive technology capable of simulating alternate realities, however, it often leads to cybersickness, causing discomfort for users. We conducted an experiment using a group of 30 participants (aged 25 ± 2.1 years) to see the alpha and delta wave changes for three conditions: Blank, Video, and Video Pause, with electroencephalography (EEG) recordings. The experiments were repeated three times (Trial 1, Trial 2, and Trial 3). The results showed a significant increase in delta wave power for Video compared with the Blank (p < 0.05). Video Pause showed a significant decrease compared to Video. Alpha waves significantly decreased during the Video compared with Blank (p < 0.05). Alpha waves during Video Pause showed a significant increase compared to Video (p < 0.05). Our study showed consistent alterations in alpha and delta waves across various visual stimuli for inducing cybersickness, and we observed that the decrease in alpha waves may be significantly associated with cybersickness rather than visual stimuli. These findings have implications for advancing cybersickness research.

晕机期间的脑电图变化：关注Delta波和Alpha波。

虚拟现实（VR）是一种能够模拟虚拟现实的沉浸式技术，然而，它经常会导致晕屏，给用户带来不适。我们对30名年龄为25±2.1岁的参与者进行了实验，观察了在空白、视频和视频暂停三种情况下的α波和δ波变化，并进行了脑电图（EEG）记录。实验重复了三次（试验1、试验2和试验3）。结果表明，与空白相比，视频的δ波功率显着增加(p
