IoT based smart walking cane for typhlotic with voice assistance

Locomotion is inevitable for human beings. The main problem for visually challenged is movement from one place to another, level crossing and identification of their current location. In case of their venture into unfamiliar environment it is a menace for them and for their fellow mates too. Therefore it is essential for the family members, organization of visually challenged to know the current location of the visually challenged. Smart walking cane acts an Electronic Travel Aid (ETA). Smart walking cane solves the challenge by detecting both indoor and outdoor obstacles and by providing level crossing guidance and current position of the visually challenged. Obstacles are detected using Ultrasonic sensors; Global Positioning System (GPS) is used to indicate the current location of the visually challenged; level crossing guidance is provided by Reflective Infra Red (RIR) sensor. The current position of visually challenged is uploaded to cloud through Wi-Fi module. Navigation information and instructions is intimated to the user of the Smart walking cane by text-to-speech converter through stereophonic Headphone. Buzzer and Vibratory circuit assists to find the distance in noisy environment too. This Smart walking cane meets the mandatory requirements of the blind people to navigate as well as to know the position and orientation of the visually challenged.
