The wearable device which is  meant for the visually impaired as it becomes difficult for them to move around on their own. A lot of devices and products have been made to make their life easier, but most of them require external assistance or may not be easy to handle. Science has also proved that visually impaired people are good listeners and that they follow sound. 

A device for the blind which helps them walk around from place to place without any assistance and also warns them about the obstacles around. It includes a belt and earphones, the belt has vibrators on four directions and sensors which detects the obstacles at a radius of 3-5 meters and helps the disabled to avoid it, as the distance between the user and the obstacle reduces the vibration increases. A GPS navigator is used to guides the way to the landmark, a Bluetooth interface provides network capabilities, allowing downloading route maps from the cell phone. As the user moves, he/she is guided when to take a left/right according to the map through the earphones. This device can also be used by cyclists, travellers, sailors etc.

The idea was not to create something new but to explore and understand what is already in the market.

 

Coding in Arduino

The belt works by following the shown code below, it detects the obstacles between 0 – 100 cm and it warns the user by vibrating. Keeping track of the direction, the vibration on the belt can only be felt on the side from which the obstruction is detected. For example, if the ultrasonic sensor detects an obstacle on the left, only the left vibrating motor will vibrate.

 

 

 

Voice panning code

Coding in Processing
This code is used for panning directing audio clips. After syncing in with your phone and choosing a destination, the belt will direct the user by an audio directing her/him to go in a particular direction using the earphone in the same direction. For example, if a person is supposed to turn left, he/she will hear beeps only on his left earphone.
