What is ISO 55186-2018

ISO 55186-2018 is an international standard that establishes guidelines for the design and use of tactile symbols to assist visually impaired individuals in navigating built environments. This comprehensive technical article provides an in-depth analysis of ISO 55186-2018, covering its background, key principles, design considerations, and practical applications.

Background of ISO 55186-2018

The need for a standardized system of tactile symbols was recognized due to the challenges faced by visually impaired individuals in accessing public spaces and facilities. Lack of consistent and easily identifiable tactile cues made it difficult for them to independently navigate and comprehend their surroundings. In response to this, various countries developed their own systems, leading to inconsistencies and confusion.

To address these issues, ISO 55186-2018 was introduced as a global standard to provide guidance on the design and implementation of tactile symbols, ensuring uniformity across different environments and improving accessibility for people with visual impairments.

Key Principles of ISO 55186-2018

ISO 55186-2018 lays down several key principles to be followed while creating tactile symbols:

Clarity: Tactile symbols should be clear, unambiguous, and easy to comprehend.

Consistency: Symbols should have consistent meanings across different contexts.

Accessibility: Symbols should cater to the needs of various users with different levels of tactile sensitivity.

Durability: Symbols should withstand environmental factors and remain legible over time.

Universal Design: Symbols must be inclusive and intelligible to users from different cultural backgrounds.

Design Considerations and Practical Applications

The design of tactile symbols under ISO 55186-2018 takes into account factors such as shape, size, texture, and placement. These considerations ensure that the symbols are easily identifiable by touch and convey their intended meanings effectively.

ISO 55186-2018 is applicable to a wide range of environments, including public buildings, transportation systems, educational institutions, healthcare facilities, and recreational areas. Tactile symbols can be used on doors, signage, maps, elevator buttons, and various other surfaces to provide guidance and information for visually impaired individuals.

By implementing ISO 55186-2018, societies can enhance the independence and mobility of visually impaired individuals, enabling them to navigate their surroundings with confidence and ease.
