“Smart Cane Indicating a Safe free Path to Blind People Using Ultrasonic Sensor”

Abstract

Visually impaired people generally use the typical white cane. There are many electronic aids for blind people in both prototype and market state. The paper introduces the problem area that motivated the work and giving an alternative solution. In this paper we propose A Safe Free Path to Visually Impaired Person Using PIC16 and ultrasonic sensors to make the cane smart. The system we propose detects the nearest Obstacle and sends back vibro-tactile feedback to inform the user about its localization. The system aims at increasing the mobility of visually impaired people by offering new and low cost cane for indoor and outdoor use which can warn them at any time when any obstacle comes in his path.
