Advanced Electronic Walking Stick for Blind
Journal Title: GRD Journal for Engineering - Year 2018, Vol 3, Issue 0
Abstract
Visually impaired persons find themselves challenging to go out independently. White cane have been used to assist the blind people’s navigation. With advancement in technology electronic walking sticks with obstacle detection sensors came for their aid. However a more advanced electronic walking stick is proposed in this paper. The proposed advanced electronic walking stick has ultra-sonic sensors mounted on it. It also uses a GSM and GPS module along with a heartbeat monitoring band. GPS module is also used to determine the location of the blind person and heart beat monitoring band is also used. For short distance obstacle buzzer is used which produce beep sound and for long distance obstacle the distance between the obstacle and the stick is given as an audio output from speaker with the help of raspberry pi. Buttons are used were each button corresponds to different operations such as activate buzzer, produce audio output, scanning of currency note using colour sensor, sending help message to corresponding mobile number with the help of GSM module.
