Inspiration

Popular methods of navigation assistance for bicyclists involves either using headphones or a monitor/display to determine directions. This inspired a desire to create a safer method. This was our primary motivation to develop Wayst. Our secondary motivation was driven by the need to improve the quality of life for the visually impaired.

What it does

A headless and soundless piece of wearable technology that enables the user to safely travel and explore new areas using haptic feedback. It also detects nearby objects (within 1 meter) and informs the user.

How I built it

  • 3D printed 4 enclosures
  • Connected 3 motors and ultrasonic sensors for front, left and back part of the belt
  • Designed a circuit to drive motors
  • Programmed companion Android App and Firmware on the Particle Core

Challenges I ran into

Hardware debugging and sensor characterization were definitely the most challenging. We had to spend extra time to develop filters to handle the sensor noise.
