應用腦電波研究虛擬實境技術對人大腦的影響
Using Electroencephalography to Study the Influence of Virtual Reality Technology on Human Brain
摘要
自1929年，德國醫生漢斯‧柏格(Hans Berger,)，成功的以腦波圖(electroencephalogram)紀錄人類的腦波活動，腦電波開始有了較詳細的文獻紀載。過去醫學界常利用腦電波進行各項療程，以腦機介面（Brain-computer Interface, BCI）為最為著名。在眾多研究者的努力之下，也開始被用於學習輔助與休閒娛樂上。近年來，隨著晶片不斷地進步，虛擬實境相較以往不再那麼地笨重與昂貴，開始有許多廠商製造相關的設備；然而，很少有抓取生理訊號作為虛擬實境的輔助工具。本研究使用VR結合腦波儀器，設計實驗讓受測者觀看一段影片，在音量、環境…等因素在相同的情況下，一次使用VR觀看，另一次使用2D螢幕觀看，並擷取其腦波。本研究總共蒐集30個有效樣本，經過MATLAB上的EEGLAG套件將腦波分析，將頭頂上14個頻道之腦波的α波與β波濾出，並計算出每個頻道功率平均，再透過統計檢定方法來驗證其是否有顯著差異，以作為腦機介面與虛擬實境結合的參考依據。

Since 1929, the German doctor Hans Berger has successfully recorded the brainwave activity of humans with an electroencephalogram. After that, more and more research Brainwaves began to have more and more detailed research. In the past, the medical profession often used brain waves to perform various treatments, and the brain-computer interface (BCI) was the most famous. Under the efforts of many researchers, BCI has also begun to be used for learning and entertainment. In recent years, with the continuous advancement of wafers, virtual reality is no longer so bulky and expensive, and many equipment about virtual reality have be created. However, few physiological signals are captured as an aid to virtual reality. This study used VR combined with brain wave and design an experiment. Let subject watch a short film. In the same situation, let subject watch it with virtual reality in the first time, and the other time, let them watch it with 2D screen. Capture the brain wave while watching the film. . A total of 30 valid samples were collected in this study. Use the EEGLAG kit on MATLAB to analyze the brain waves, and filter alpha and beta waves of the brain waves on the top 14 channels. Finally, the average power calculated for each channel, and then through statistical verification method to verify whether there are significant differences. As a reference for the combination of brain-computer interface and virtual reality.
