11.3.5. Signage and Wayfinding

• Raised letters and braille on door signs.

This point emphasizes the importance of using raised letters and Braille on door signs. Raised letters are tactile features that can be felt by touch, enabling visually impaired individuals to read the sign through their fingers. Braille, a system of raised dots, allows those who are blind to understand the sign's information without needing to see it. Together, they make essential information accessible to a wider range of individuals, ensuring everyone can navigate a space effectively.

Think of how you might read a sign in a new place. If that sign had raised letters and Braille, even someone who can't see could touch it and know what room they are entering, just like how you might use your sense of touch to identify different textures on your clothing.

• High contrast colours (e.g., white on dark blue).

High contrast colors in signage greatly enhance visibility, making it easier for individuals, especially those with low vision, to read and understand information. For example, using a bright color like white on a dark blue background creates a stark contrast that the eye can easily differentiate, helping users to quickly identify directions and important information.

Imagine trying to read a book with light grey text on a white page—it's difficult and frustrating. Now think about a blackboard with white chalk writing; it's easy to see and understand. This principle is similar in signage: the right contrast can make all the difference.

• Symbols conforming to ISO standards.

Using symbols that conform to ISO (International Organization for Standardization) standards ensures that signs are universally recognized. ISO symbols are designed to be simple and clear, making it easier for everyone, including non-native speakers and those with cognitive disabilities, to understand their meaning. These standardized symbols facilitate effective communication in signs and help to minimize confusion.

Think about how a 'no smoking' symbol looks the same in many countries; it uses a simple graphic that universally conveys the message without words. This is like an airport sign indicating a restroom using a stick figure—it's clear and understandable, no matter where you are from.

• Audio announcements in transport and large facilities.

Audio announcements provide crucial information for individuals who may not be able to read signs, including those who are blind or visually impaired. In transport systems and large facilities, these announcements keep everyone informed about changes, such as train arrivals or exits, ensuring safe and efficient navigation throughout the environment.

Consider how in modern public transport, you often hear announcements about the next stop or delays. This auditory information is essential for someone with visual impairments who relies only on sounds to determine where they need to go.
