摘要

目的：根據統計，全台灣的視覺障礙者人數高達56,039人，無論是出行還是在家，視障人士的生活有著許多問題與不便。本研究希望透過物聯感測器應用結合拐杖，設計出可輔助盲人之智能導盲杖，並且結合手機應用程式，建構出一套輔助盲人日常生活便利性之物聯系統。方法：感測端運用Arduino開發板結合多種感應器，安裝於盲人用拐杖，可進行前方障礙物偵測、環境光線黑暗處亮燈提醒路人、緊急求援機制等功能。透過手機APP設計應用程式，提供目前定位記錄、公車報站機制及NFC快捷應用等功能。此外，開發網站應用程式，提供管理者及家屬查詢及管理等相關功能。結果：開發出一套完整的輔助盲人日常生活之物聯系統，感測端裝置於盲人拐杖可進行障礙物偵測及光源感應，手機端應用程式可與感測端連動進行警示，且可連結開放資料庫查詢公車到站資訊以語音播報，及運用NFC快捷感應提供定時通知功能，而所有資料視需要均可同步於後端資料庫，利用網頁應用程式提供管理者及家屬查詢相關資料。結論：結合手機APP與智能導盲杖開發一套完整物聯系統，提供緊急撥號、定位資訊、避障測距、計時通知與公車報站這五大功能。也結合網站提供關於此物聯系統詳細的介紹與管理使用者資料的功能。透過本系統的使用可提升盲人安全性及日常生活便利性。

Objective: Statistics show that 56,039 people in Taiwan are visually impaired. People with visual impairment often experience numerous problems and difficulties during activities of daily living, both indoor and outdoor. This study was conducted to integrate Internet of Things (IoT) sensors into a white cane to design a smart white cane that can aid people with visual impairment. Subsequently, the smart white cane was combined with a mobile app program to construct a convenient IoT system for aiding the everyday activities of visually impaired people. Methods: At the sensing end, Arduino board integrating different types of sensors was installed in a white cane. These sensors include a sensor for detecting obstacles ahead, an ambient light sensor that lights up in dark environment to remind pedestrians, and a sensor that features an emergency response mechanism. A mobile app was designed to provide location records, bus stop announcement mechanism, and near-field communication shortcut applications, among other functions. In addition, a website app program was developed to provide enquiry and management related functions for administrators and family members. Results: A complete IoT system for aiding the everyday activities of visually impaired people was developed. Sensors were installed in a white cane for obstacle detection and light sensing. A mobile app program can be linked to these sensors for warning purposes, and it can be connected to an open database for bus arrival queries and reporting. Near-field communication shortcut sensing was used to provide scheduled notifications, and all data can be synchronized with back-end database as needed. A webpage app program was used to provide administrators and family members with relevant information. Conclusions: A complete IoT system integrating mobile app and smart white cane was developed in this study. It provides five major functions: emergency number dialing, location information, obstacle avoidance and distance measurement, timer notification, and bus stop announcement. The IoT system was also integrated with websites to introduce details about this IoT system and provide functions for managing user information. The developed system can be used to improve the safety of visually impaired people and make their lives easier.
