Description
Summary:The visually impaired/blind people face many challenges and seeks help from the other people even for their daily routine life due to various complications. Also, they could not go independently outside, even for their basic needs and mentally depressed due to their current inability. A wearable navigation system/device is proposed and developed to help the blind people as well as the partially blind people or challenged people. The devised unit/prototype consists of the displacement measuring sensor for the detection of the obstacles and depth. The data received from the IR and Ultrasonic sensor is feed into the Arduino UNO Microcontroller and it is processed. The output from the controller is given to the impaired people through the wireless voice playback modem, to alert them when they found obstacle or collision. The receiver end receives the corresponding current position values through the navigation systems and the static, dynamic condition of the impaired people is measured using mems accelerometer and the same information (latitude, longitude) is shared as SMS to their family members or guardian to monitor them, during any emergency. The proposed guidance cane is a cheap, simple, user friendly and smart device.
