This is from a research that a couple of my friends and I conducted. We studied the usage of the Bangalore City operated bus system by the blind. Our findings I think would hold true in many parts of India and the world.
Some key findings:
1. Blind people have a concept of landmarkswhich relies on sounds, smells and kinaesthetic. They use this as a way to help them get around.
2. Driver discipline is the biggest problem: In Bangalore as in most of India, the busses don’t always stop exactly at bus stops. This presents multiple problems for the blind: safety in and ability to get on and get of the bus, way finding after getting off the bus etc.
3. Braille signs do not work in India: Blind people in India are hesitant to touch Braille signs in public areas because of cleanliness and hygiene concerns.
