Tactile Ground Indicators (TGSI's)

People with disabilities have the right to dignified, safe and independent access to buildings and other public facilities and services. As the population continues to age, it is estimated that the percentage of people with a degree of vision impairment will also grow significantly. The responsibility to cater for this segment of our population rests on those who design and build structures, in order to ensure a safe and easy access to public facilities.

Up to 90% of people with vision impairment still retain some sight. For this reason, luminance contrast can play an important role. People with vision impairment use luminance contrast as well as tactile cues as a means of guidance.
