Please be advised that a New Work Item Proposal has been loaded to the BSI Standards Development Portal for comment. 

Any comments received will be submitted to the national committee “PH/9/-/1 Ergonomics” for consideration when deciding the UK response to the associated Standards Development Organisation. 

Proposal: ISO/NP 23456-2 – Dynamic signs in physical environments — Part 2: Visibility, safety, and accessibility 

Please visit: ISO/NP 23456-2

Comment period end date: 10/12/2024

Scope

This document describes the design requirements and recommendations for dynamic signs from the perspectives of visibility, safety, and accessibility, based on ISO 23456-1.

The design requirements and recommendations includes “How to Design,” “How to Display Moving Elements,” and “Where to Place” dynamic signs.

“How to Design” describes how to design a sign that ensures visibility. It also describes the legible display design requirements for people with special requirements such as low vision as well as the elderly. “

Purpose

This standard is a part of the umbrella structure of the Dynamic Sign series developed in ISO/TC159/SC5

A dynamic sign is an information presentation technology that changes its position, size, brightness, and content. Furthermore, this change has the advantage of increasing attractiveness, identification, readability, and comprehensibility. Therefore, it is necessary to specify the design requirements to maintain these visibility aspects. On the other hand, the dynamic component of the image may cause undesirable biological effects, such as photosensitive seizures (PSS) due to flashing frequency, repetitive patterns, etc., visually induced motion sickness (VIMS) due to visual motion stimuli involving rotation or translation to a wider field of view. In addition, depending on the location of the sign, it may cause stagnation of human flow, reverse flow, interference, or confusion, which is not the intention of the installer.
