摘要: 改善車輛導航系統對駕駛安全的影響,已成為行車安全最重要的議題之一。目前大部分研究主要集中在車輛導航系統的介面設計和使用者經驗,但對其在實際車輛控制以及相關大腦機制的運作則較少探討。因此,在本研究中,我們設計了一個實車道路駕駛實驗,受試者會根據車內語音導航系統的指示,執行變換車道的任務,透過同時記錄腦電波訊號與車體資訊,探討語音導航系統對車道變換的影響以及相關之大腦動態活動。結果發現: 語音導航的提示會明顯地影響駕駛者的車速控制。另外,前額葉腦區的δ與β頻帶能量有明顯的上升趨勢,這可能與車道變換動作的準備以及決策有關。此研究所發展之車體資訊判斷模型以及車道變換之腦波特徵,可提供做為發展導航裝置效能之評估系統。
How to improve the interference of in-car navigation system is the important issue for the driving safety. Despite large amounts of research assessing the usability and interfaces, there has been much less investigation of brain activity by the auditory presentation navigation while driving in the road. In this study, we designed an real-world experiment with the electroencephalography (EEG) recordings and in-car information to explore the brain dynamic activity while driver performed the lane-change task followed the auditory instruction from in-car navigation system. The results showed that auditory cue can influence the speed control and also increase the frontal delta/beta power that are related to motor preparation and decision making during lane change. Specific vehicle information (lateral acceleration and heading angle) with EEG features can be a better lane-change assessment for future naturalized driving study.
