It is very much difficult to uphold the journey when you are visually impaired. I’ve experienced the difficulties arises while navigating the street in the visual impaired situation. There is no solution yet for these people to help to navigate the street.

But BackMap is now there for those people which came out of TechCrunch Disrupt NY’s 2017 Hackathon explaining the useful of the visually impaired people’s. BackMap is a backpack that vibrates to let you know when to turn right and when to turn left.

the BackMap will work and walk you through the street to the destination without any trouble and without using your phone. While leaving for outside, input your all location via the app and have your BackMap navigate you to the destination. BackMap does this using Esvi’s PubNub Block. It is also useful inside home, office, apartments, malls, and more. It can show ou bathroom in your home, certain stores in the mall, office inside the company, and good locations of the apartments.

“I think that’s a pretty cool feature for people who are visually impaired because if you walk into a store, you might not know how to navigate to certain places, ” Shashank Sharma told after his team’s presentation.

If you think about the mass crowd place I which you have to search a certain place which is completely new to you, it’s very difficult to find out. For instance, it can be hard to navigate inside a massive conference like Disrupt or inside a Westfield mall. The team also imagines other pedestrian and bikers using BackMap concluding that they don’t have to take out their phones or use headphones while they are around.

Here is a demo video which shows the presentation at Disrupt NY Hackathon 2017

BackMap is equipped with Raspberry Pi-Controlled Motor in each step. It only cost the team about $40 to create this haptic feedback system. As of now, this BackMap is the one cheapest system prototype developed.

At the end, team disclosed about their vision in the future. They say they envision is to bring the functionality to a smartwatch and another wearable device to help the vision impaired people’s.
