Research Topics

穩態視覺腦機介面遊戲設計

SSVEP Based BCI Gaming Design

隨著科技發展,近年來腦機介面技術日益精進,腦波控制開始受大家注目。本系統以穩態視覺誘發電位 技術開發,畫面中可同時發出多種不同頻率的閃爍,使用者可擇其一注視,此時人腦枕葉區會釋放相同 頻率信號。透過腦波信號成分關聯性分析,可快速回推使用者注視的項目為何者,進而達到腦波控制玩 遊戲的效果。

With the ever-changing nature of science, and the improvement of BCI technology, brain wave control has started to become famous. Based on SSVEP technology, this system evokes different frequency's signal from our Occipital Lobe with icons on the screen flickering in different frequency. By analyzing the signals, we can play the game with our brain waves.

肌電訊號手勢辨識與骨架追蹤之新型人機介面

Man-Machine Interface: EMG based Gesture Recognition Control and Skeleton Tracking

一直以來類似Kinect等體感裝置受制於深度影像限制,無法實現同時使用手勢辨識與骨架追蹤之人機介面,以致操作體驗上不直 覺不靈活。本新型人機介面利用肌電訊號分析技術製作手勢辨識裝置,結合深度影像裝置Kinect,實現同時使用手勢辨識和骨架 追蹤之效能,以遊戲操作為體驗,讓使用者體驗更直覺更靈活之嶄新操作介面,感受更高的高自由度、直覺性及沉浸感的虛擬實 境遊戲。

Motion sensing controller has been limited by Depth Image, which makes it impossible to achieve gesture recognition control and skeleton tracking at the same time, and cause inconvenient user experiences. With our new man-machine interface, combining EMG based gesture recognition control and Kinect, a Depth Image device, we successfully achieve gesture recognition control and skeleton tracking at the same time and let our users experienced a more convenient and high DOF virtual reality game.

疲勞監測系統

Fatigue Monitoring System

交通事故的發生率又以疲勞駕駛占了極大比例,若能藉由生理醫學電訊號得知駕駛人目前的生理狀態,評估駕駛行為下之即時反 應時間,提醒駕駛人以提高警覺性,可達到有效降低疲勞駕駛所導致的事故率。本系統以無線乾式電極腦波帽搭配即時線性運算, 同步分析腦電及眼電訊號特徵,開發出一套可靠且精準的駕駛疲勞評估演算法。可即時分析駕駛者的即時反應時間,再推算疲勞 狀態的變化,進而對駕駛者發出警報,此即時監測神經反饋系統,使人類的安全及生活更加多一分保障。

Among all the traffic accidents, the rate of fatigue driving is the highest. If we can evaluate our physiological state by physiological signals in time, we can warn the drivers and lower the rate of traffic accidents. Combining wireless EEG cab, eye tracking device, and our algorithm, we have a precise neural feedback system which can warn the drivers immediately and makes our life safer.

探討模擬戰爭場景下行為抑制網絡

To Study our Behavioral Inhibition System in Battlefield Simulator

先前研究多使簡易符號設計實驗,並已對抑制網絡系統有了一定的了解,本研究為了可瞭解真實環境下的抑制網絡設計了具有威脅 性的場景-戰爭場景。本研究發現前運動輔助區(preSMA) 、右側額葉中迴(rMFG)及右側額葉下迴(rIFG),皆在傳統符號場景下 與戰場模擬場景下成功抑制時有正向活化。fMRI結果也指出當人類在威脅情況下抑制行為時, 右側顳頂交界腦區(right temporoparietal junction, TPJ)將涉及抑制控制的調解。

Previous research studied behavioral inhibition system (BIS) with a very simple task. In our research, we simulated a very real and threatening circumstances to study BIS. The research indicates that preSMA, rMFG, rIFG are activated when inhibiting. Also, by fMRI, we found that the activation of right temporoparietal junction is related to inhibition control under threatenings.

生命徵象(心跳、體溫、呼吸)監測系統

Vital Signs Monitoring System

現今每位護士照顧人數高達13位病患,醫院固定每4小時循房一次,並量測病患之心跳、呼吸及體溫,相當耗時卻不能讓病患得到 更好的醫療照護。我們開發出一套系統,只需得到心電圖及「體表」體溫,即可推算出心跳數、呼吸數及「核心」體溫,並即時將 數據以無線傳輸傳送至護理端,藉此不僅能減少護理人員的工作量,每位病患也能得到更好的醫療品質。

Every nurse has to take care of 13 patient on average, and makes their rounds every 4 hours. Heart rate, respiration and body temperature are measured, which takes a lot of time. We've developed a system with only ECG signals and shell temperature required, we can calculate the patients' heart rate, respiration and core temperature. Combining the algorithm with wireless system, we can reduce the nurse's workload and enhance the healthcare quality.

智慧芳香舒眠系統

Smart Sweet-Scented Sleep System

睡眠在身心各方面有著關鍵的影響,舉凡情緒、壓力、記憶及健康,都和睡眠息息相關。然而,睡眠品質不佳是現代人的通病, 據台灣睡眠醫學會調查,國人睡眠滿意度從2000年的89%下降至2009年的63%,並統計出現今有高達六成的國人擁有失眠現象。 為解決大眾的睡眠問題,以入睡過程、睡眠深度、最佳起床時機等角度切入,開發並設計出此套居家型的「智慧芳香舒眠系統」。 並發展一套睡眠專家系統結合無線腦波帽系統(Mindo-4s)與睡眠軟體(iSleep),即時評估睡眠周期,讓使用者在結束量測時可 立即得到整晚的睡眠品質評估報告。

Sleeping affects our emotion, stress, memory, which plays an important role in our life. According to the Taiwan Society of Sleep Medicine, 60percent of the Taiwanese have Insomnia. In order to solve the sleeping problems, we've developed a Smart Sweet-Scented Sleep System. Combining wireless EEG cab and the iSleep software, it can evaluate our sleep quality from many different aspects, and it will be easier for users to find out where the problem is.
