This project is about a portable voice navigation system for visual impairment,It helps people with visual impairment to navigate to the destination conveniently and safely in their daily life,When the visually impaired enter the home,There are infrared sensors and blue bud modules at the door,Sense the visually impaired and transmit the starting coordinates (0,0) to the mobile phone or tablet through the Bluetooth module,Then the acceleration sensor and electronic compass are used to detect the distance and direction of the visually impaired,The data of acceleration sensor and electronic compass are transmitted to mobile phone or tablet computer through Bluetooth module,Calculate the coordinates of the movement of the visually impaired in the room,Important indoor entrances and exits include bedroomsThere are infrared sensors and blue bud modules in bathrooms,The coordinates of the visually impaired are sensed and transferred to mobile phones or tablets through the Bluetooth module to correct the coordinates of the indoor movement of the visually impaired,Pre input home map with mobile phone or tablet,Input the destination with voice by the visually impaired,The text to speech (TTS) tool built in the mobile phone or tablet can tell the visually impaired how to get to the destination.本創作係有關於一種用於室內的攜帶式視障語音導航系統，係在日常生活中用語音幫助視障人士在室內能便利與安全導航到目的地，視障人士在進家門後，門口有紅外線感測器和藍芽模組，感應視障人士並將開始座標(0,0) 透過藍芽模組傳到手機或平板電腦，接著使用加速度感測器和電子羅盤來偵測視障人士走路的距離與方向，並且將加速度感測器和電子羅盤的資料透過藍芽模組傳到手機或平板電腦，計算視障人士在室內移動的座標，室內重要出入口包括臥室、浴室等等均有紅外線感測器和藍芽模組，感應視障人士並將座標透過藍芽模組傳到手機或平板電腦來修正視障人士在室內移動的座標，配合手機或平板電腦預先輸入的居家地圖，由視障人士用語音輸入目的地，即可由手機或平板電腦內建的文字轉語音(Text To Speech(TTS))之工具告知視障人士如何到達目的地。
