Smart Walking Stick Design For Blind People

Abstract

In this study, it was aimed to design smart walking stick in purpose of detect obtracles that cause danger for blind people. The selected sensors and electronic components were programmable with Arduino. Ultrasonic distance sensor was used for detect obtracles in determined closest distance. A buzzer was used to provide audible alert when obstracles were detected via ultrasonic distance sensor. Additionaly, experimential studies were applied on GPRS sensor which is used for send locational information via SMS to caretaker of blind person when she or he lose the way.
