Sensible Ground (Visually Impaired Walkway)

How Useful Is Sensible Ground for Visually Impaired People?

First, let’s talk about the color of the tactile surfaces. Only a small percentage of people with visual impairments can see anything. Most people with visual impairment have some degree of vision. This is why tactile surfaces are made in bright colors such as yellow and red. These colors are easier to see by partially sighted people.

Also, red tiles are often used to indicate a controlled transition. For example, you are more likely to see red tactile tiles at traffic and pedestrian light intersections. This indicates to the partially sighted person that they can use the pedestrian light to cross the road. Yellow tactile tiles are used in uncontrolled transitions.

People with visual impairments use a cane to feel the road ahead. When the cane touches these patterned tactile tiles, the carrier receives various information about how to move forward.
