| Summary: | Vision plays a paramount role in our everyday life and assists human in almost every walk of life. The
people lacking vision sense require assistance to move freely. The inability of unassisted navigation
and orientation in outdoor environments is one of the most important constraints for people with visual
impairment. Motivated by this problem, we developed a simplified and user friendly navigation system
that allows visually impaired pedestrians to reach their desired outdoor location. We designed a Braille
keyboard to allow the blind user to input their destination. The proposed system makes use of Google
Directions API (Application Program Interface) to generate the right path to a destination. The visually
impaired pedestrians have to wear a vibration belt to keep them on the track. The evaluation exposes
shortcomings of Google Directions API when used for navigating the visually impaired pedestrians in
an outdoor environment. |
