The Goal

I wanted to build a pair of glasses that helps you "see" obstacles using sound. The goal was to use an ultrasonic sensor to detect how far away things are and give real-time feedback.

The Parts

I used an HC-SR04 ultrasonic sensor mounted on regular glasses frames. A small computer reads the sensor data and calculates the distance to the nearest object.

  • Sensor: Ultrasonic distance sensor.
  • Speaker: Small built-in audio driver.
  • How it works: The glasses beep faster as you get closer to something, making it easy to tell where obstacles are.

Design

I kept the electronics small so the glasses stay comfortable to wear. I also routed the wiring along the arms of the frame to avoid snagging or breaking during use.

What I Learned

The beeping system worked well for navigating around things. The main issue was that it only looks straight ahead — it doesn't see what's to the sides. To fix this in a future version, I'd need to add more sensors for a wider field of view.
