Inspiration - I was in a car and seen a blind person cross the road and people were honking at him because he was taking a long time to cross the road. We wanted to help blind people make their life a lot easier.
How it works - The ultra sonic sensor mounted on the blind cane senses any object that's placed in a given direction. A micro controller is programmed such that it will read the sensor data and triggers a message of an object is within 90cm at the direction the blind cane points. The message is then transmitted to a computer which is then sent to the smart myo arm band. The myo arm band will provide haptic feedback to the blind person.
Challenges I ran into - Making the communication path precise and reliable was very challenging. The myo reading a message made by an external controller was challenging to implement. The haptic feedback accuracy strongly matters to the blind person.
Accomplishments that I'm proud of - We are really proud of the fact that we are able to change peoples lives with this hack. We believe a blind persons life just got better with MyoBlind because a lot of their problems will be eliminated with this product such as crossing a road, doing basic functionalites in their house and many more.
What I learned - We learned how to use the myo sdk to fit our own needs. The communication path was also something we had never implemented before so it was a great learning experience.
What's next for MyoBlind - Possibilites for MyoBlind are endless. We are currently working on changing the intensity of vibration depending on how far and how close a obstacle is. In the future, we will be taking this to the next level by allowing a blind person to be able to be sit in a idle state and control things around them such as turning on/off the lights, turning on/off the heating and cooling system. We feel these features will change a blind persons life because they dont have to worry about doing basic functionalities with a simple gesture done with their hand such as making a fist or moving their hand left/right.
