注意力訓練可以在遊戲中透過在腦機介面（Brain Computer Interface, BCI）和Unity所結合的平台，使大腦與遊戲中角色直接溝通。本研究設計森林小雞虛擬實境場景遊戲，配合NeuroSky公司的單通道腦波儀（MindWave Mobile）來讀取腦電波（Electroencephalogram, EEG）訊號特徵於注意力訓練場景中。受測者為作者本人，透過專注與放鬆冥想來控制森林小雞的行進軌跡，並將演算法歸類完成後的腦波數據特徵作為操控森林小雞左右方向的位置移動來讓森林小雞維持於中線（石頭排列線）上，計算出訓練的正確率。本研究實際測試結果分為兩天進行測試而得正確率之樣本，每天平均做十次的實際測試，計算出兩天的平均正確率分別為69.6%、69.8%，利用t檢定計算且P>α，結論得出森林小雞注意力訓練之虛擬實境遊戲系統是成功的並且對於受測者是方便也穩定實用之系統，未來也希望可以應用於臨床專注力訓練之復健相關研究。

Attention training can enable the brain to communicate directly with the characters in the game through the combination of Brain Computer Interface (BCI) and Unity. In this study, the virtual reality scene game of Forest Chicken was designed, and the single-channel brain wave device (MindWave Mobile) of NeuroSky Company was used to read the characteristic signals of brain waves in the attention training scene. The test subject is the author himself, who controls the walking trajectory of the forest chicken through concentration and relaxation meditation, and uses the brain wave data features after the algorithm is classified as the position movement of the forest chicken in the left and right directions to keep the forest chicken. On the center line (stone arrangement line), the correct rate of training is calculated. The actual test results of this study are divided into two days of testing to obtain the correct rate of samples. The actual test is performed an average of ten times a day, and the two-day average correct rate is calculated to be 69.6% and 69.8%, respectively. The t test is used to calculate and P> α, the conclusion is that the virtual reality game system of forest chicken attention training is successful, and it is a convenient, stable and practical system for the subjects. It is hoped that it can be applied to the rehabilitation related research of clinical attention training in the future.
