摘要：This paper presents a smart stick system for assisting blind or visually impaired people. The smart stick acts as a vision assistant to enable visually impaired people to find difficulties in obstacles detection and dangers in front of them for autonomous navigation. Unlike existing papers, related to obstacles detection means: ultrasonic sensor, infrared sensor, and water sensor, alarm modules: buzzer, sound, and voice statement, and a location finder like the GPS/GSM system, the proposed system integrates all these technologies for the benefits of the blind. The system is designed to act like an artificial vision associated with an alarm unit, and a location finder of the blind. The Global Positioning System (GPS) and Global System for Mobile communications (GSM) are interfaced to the microcontroller to detect the blind person location. The feedback from the real test was positive. The average of avoidance accuracy is 88.75%.
