What Are Tactiles? What are tactiles indicators? Tactile ground indicators are used to help the blind and visually impaired people orient and remind some pending hazards or obstacles. Visually impaired people can detect TGSI tactiles through the luminous contrast of the surrounding ground substrates and the sensory detection of the sole. Many people are blind or visually impaired, and more people's visual efficiency is reduced. People over the age of 65 are the best fit for this category. With the continuous growth of the population over 65 years old, the number of visually impaired people will grow higher in the future. Type of Tactile Directional Indicators: TGSI consists of two types: warning TGSI and directional TGSI. The most common materials of TGSI include stainless steel, brass, plastic, ceramics, and concrete. Both directional and discrete TGSI are made in two different forms: discrete form (individual) and integrated form (cushion).

Tactile indicators are used to help the blind and visually impaired people orient and remind them of some pending hazards or obstacles. Several factors must be considered when selecting and installing the appropriate tactile directional indicators for a given environment. First, you must evaluate the demand or requirement (usually performed and specified by the architect) of TGSI in a specific area. Installing TGSI in an area where it is not required may confuse the visually impaired. In this case, it may cause more harm than good vision and may lead to legal problems.
