Public spaces can be especially difficult for people with vision impairment to navigate safely as they are unfamiliar with the obstacles that may be present in their path. A promising strategy that was first implemented in Japan and then replicated throughout the world is called tactile paving. Inspired by Braille, the reading system of the blind, tactile paving essentially consists of placing textured tiles to form a guiding path that can be felt through the sole or with a cane.
What are Tactile Ground Surface Indicators?
Tactile Ground Surface Indicators (TGSIs) are tools designed to assist visually impaired people with navigating public spaces safely and easily. TGSIs work by enabling people to identify the pattern so that they can get used to these areas and navigate a path through which they can travel with ease.
