Abstract

Abstract: visually impaired and Blind people find difficulties in detecting obstacles during walking in the street. This system is intended to provide artificial vision and object detection, real time assistance via GPS by making use of Raspberry Pi. Thissystem consists of ultrasonic sensors module, module of gps, and the feedback is receive through audio, voice output works through TTS (text to speech). This system detects an object around them and sends feedback in the form of speech, alert messages via earphone and also provides navigation to specific location through gps. The purpose of the system is to provide a low cost and efficient navigation and obstacle detection for blind so that they can walk independently.
