Abstract:
Blind people daily encounter many difficulties such as walking on the road, finding right path. In this project the interactive cane comes as a solution to enable them to identify the world around by integrate the traditional white cane with circuit consisting of microcontroller and ultrasonic sensors to detect obstacles ( forward ,above knee ) and pits .In addition there is water sensor to detect water on the ground. The result of ultrasonic sensors is alarm with different rings for each sensor, and vibrations for water in the path. All these alarms and vibrations will be stopped once the guide cane is taken away from obstacles and water. This can be considerably decreases the risk of the blind people injuring themselves. The circuit designed firstly by Proteus Virtual System Modeling then after the guide cane sensors are actually assembled. After test we found the sensors are working at efficiently of 87%.
