本研究主要之研究目的為協助視障者在不熟悉之路途中,因為失去方向或迷路而無所適從,於是在導盲杖上設計具有偵測位置與方向之RFID感測模組,並且將路徑規劃演算法加入於系統中,提供視障者能在不熟悉環境裡找到自己所處於的位置與方向,並提供導航之功能。
一般研究上所使用的方法多利用超音波感測器判別前方障礙物距離視障者多遠,或是利用機器人導引方向,並將感測器裝置於機器人上,視障者無法有較大的行走自由度,會變得綁手綁腳,且機器人製作上價格昂貴。然而在多方面考量後,我們採用最近幾年來極為熱門且技術越來越成熟之RFID作為智慧型導盲杖感測器應用,希望能讓視障者在室內環境中自在的行走;研究中藉由手杖裝上RFID讀取器作為室內定位的設備,將室內空間地板上佈滿RFID電子標籤,依照RFID標籤之特性,每一個標籤會有一個屬於自己之辨識碼,因此經由RFID導盲杖接觸到電子標籤後,可得知視障者目前位置,若視障者迷失方位後,可透過系統之方向判別功能取得所在方向,並且將訊號回傳於系統主控端,主控端再利用所得訊號將語音透過藍芽耳機告知視障者,視障者也可依照自己想到達之位置,選擇路徑規劃之功能,系統會經由使用者之需求以Dijkstra's演算法規劃最短路徑,協助盲人快速指引最佳路徑。
The main purpose of research is to assist the visually impaired who are not familiar with environment, it would cause somebody to be confused because of losing direction. We set RFID sensor which can detect directions and the position to the white cane, and utilize the path-planning algorithm to this system. The method of research is to provide the visually impaired to find the position and the orientation, and give them the function of navigation.
Previous studies use ultrasonic sensor to detect the distance between the walker and the obstacle or to direct the route through the guidance of robots. However, the visually impaired cannot get enough freedoms from it. Moreover, the cost of the development of the robot will increase. With respect to these concerns, we apply the most popular and mature technique—RFID to the guide cane sensor, hoping to give more freedoms to the visually impaired in indoor environment. The study is to combine the RFID reader with the cane as indoor positioning device. Each RFID tag spreading elaborately in indoor floor has one specific verification number. Once the RFID guide cane touches the electronic tag, the location of the visually impaired can be identified. If the visually impaired lost his way, the direction-detect function will get a RF signal. Then, the signal will feed back to main server. The main server will inform the visually impaired via the voice system of the blue tooth device. Besides, the visually impaired can use path-planning device with synergy of Dijkstra’s algorithm that helps the visually impaired to find the shortest path.
