Özet

This paper presents a developed device to solve the problem of moving and navigating of visually impaired and blind people. This device, called Ultrasonic Assistive Headset, is light, simple and low-cost option compared with other assistive devices. Ultrasonic Assistive Headset will guide for them among obstacles by employing ultrasonic distance sensors, microcontroller, voice storage circuit and solar panels to be battery-free. In proposed method, ultrasonic waves arrive to the ultrasonic sensors on the spherical membrane of the headset after sending this waves from ultrasonic distance sensors reflection from obstacles. A microcontroller determines the location of the obstacles according to the sensor ID and the information of distance. The system produces an voice data defining the location, and then it speaks to blind person where the obstacles are. Ultrasonic Assistive Headset can be used easily by them both indoor and outdoor, so they can avoid obstacles quickly and accurately.
