The History of Tactile Indicators: A Quick Overview
Tactile walking surface indicators were first introduced into the streets of Japan in the 19th century and then gradually spread in the world. Seiichi Miyake developed these tactile indicators. For cultural reasons, the color of the tactile surface indicators may not be standard. The reason is to match the color of the floor.
With the advancement in technology and research, the modern tactile walking surface shapes can classify into two codes, they are:
1. The first one has small round protrusions on the surface that can be felt through the shoe’s sole.
2. The second tactile surface is a directional aid with long and thin bumps.
However, many kinds of tactile paving have been developed and installed as an experiment. This built a confusing situation for both visually impaired and blind people. Generally, the color is used to identify the right direction. If the correct is not defined, then it may create confusion.
This all was a quick brief about the tactile surface indicators. Now, let us move a step ahead and know some interesting facts about tactile surface indicators.
Some Interesting Facts about Tactile Indicators:
1. Tactile surface indicators, aka tactile paving, are usually a group of patterned pavers or tiles applied sideways to assist the right direction to visually impaired or blind people.
2. They are also popular by different names, tactile tiles, detectable warning plates, tactile indicators, truncated domes, and tactile ground surface indicators.

4. Tactile paving is usually available in yellow or another bright color contrasting to the nearby surrounding area, indicating a secondary warning to visually impaired people.
5. Usually, tactile paving has various standards and requirements governed by each country. The officials determine the shape, size, color, and placement.
6. Australia, Britain, and Japan were the first countries that adopted tactile surface indicators. Canada and the United States embraced the invention in the 1990s.
