GPS Navigation for the Visually Impaired
- 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
Examples of audio and frequency varieties used to notify the user of an obstacle and approximate distance.
