We were inspired with the idea that we can use our current knowledge on technology to create something that can actively make a difference on people all around the world. The fact that we can make good use of what we learned for fun is really gratifying and shows us direct results.
What it does
The project finds the distance to an object and the speed of it using an ultrasonic sensor. That data is then translated onto a map which shows the user and the object and signals a beep whenever the distance between the two come to less than 7 cm to alert the visually impaired person that there is an obstacle
How we built it
We built it using an ultrasonic sensor and Arduino along with React
Challenges we ran into
We ran into many challenges like finding out how to create a map or how to send data to the website or how to process it. We ran into issues that included our own technical limits and just limits that the ultrasonic sensor had that we couldn't account for.
Accomplishments that we're proud of
We are proud of the fact that even though we had a messy start because we didn't have a base idea and spent much of the first 4-5 hours not doing much, we still ended up with something that was functional and was capable of being applied practically.
What we learned
We learned about the issues blind people face everyday along with new knowledge on react at the end of the day. We all learned some new syntax, or new technology, or even a glimpse into something we never interacted with before
What's next for BeepForBlind
Some future applications of this could include using machine learning to better differentiate between various objects and using a better sensor like a LiDAR to create a 3D model of the room or outdoor area. Better hardware in general along with a 3D map that could not only apply to the visually impaired but also the deaf to figure out where sources of sound are coming from.
