Smart Glasses for the Blind

The aim of our project is to hopefully inspire people to use their creativity to develop innovative, cost-effective, and practical solutions to issues regarding the visually impaired. Our project is the smart glasses for the blind, a small, portable pair of glasses serve as a prototype for wearable tech that can allow the visually impared to recognize basic objects in front of them. The smart glasses can be be "trained" to recognize multiple objects by their colour, and output text-to-speech to inform the user of what they are looking at.

Supplies:

  • Glasses (something with a large, sturdy frame)
  • Arduino Uno/Genuino
  • wires
  • Talkie library (https://github.com/going-digital/Talkie)
  • speakers
  • audio amplifier (only if speakers above aren't super small)
  • hot glue
  • 9v battery
  • 9v battery cable
