GPS Navigation for the Visually Impaired

DESIGN

  • Used a variety of sound and frequency combinations to communicate the type of stimuli and the approximate distance away
  • Obstacles had a specific sound and the frequency would increase/decrease based on the users proximity 
  • The video is of the product in prototype stage with full GPS and audio integration.
  • We used hard-coded GPS locations (detailed on the map below) to create an imaginary obstacle course
