Blind people face a lot of problems when it comes to commuting from one place to another. All they have for their support is a normal stick, which extends upto just some centimeters, making them prone to falls and hence injuries. Another problem is these people are not accepted by the current society. So, no one comes to help them when they are in some danger or problem.
So, to tackle the above problem I have created a system just for them. This system is equipped with obstacle detection in close proximity using an ultrasonic sensor, GPS integration for Location services and Audio output for the Blind person, accessible via a 3.5 mm audio jack.
Moreover, there will be an android app for the people willing to help such people. So, whenever the SOS switch is turned on, the user will get an alert in his app. I have used the Sony Spresense as the main board for this project. This project is already explained in detail on my Hackster Handle. Here's the Link :
