Observations during the 2011 Tsunami disaster in Japan showed that the colour of signage matters a lot. A short research paper outlines the colours and colour combinations that are easily seen and interpreted quickly by people who have one of the colour blindness conditions. The result is colour combinations for everyone.
The results of this study and other colour studies are reflected in the Japanese standards for the paint, printing and design industries. The colour scheme-set contains 20 colours and is divided into groups depending on whether things are small scale or large scale. Bright pink turned out to be a colour for large signage. For more on the colours go to the Open Journal of Social Science and download the five page article, “Color Barrier Free Displays in Disaster Situations”.
University campuses are some of the most confusing places to visit. There seems no sense of order with buildings set up higgledy-piggledy fashion. Finding you way takes more than a campus map. Given that most campuses have buildings added as the years go by, creating a good wayfinding system is always going to be a problem. However, learning from users is a good start.
Wayfinding around an Oslo university is the subject of an interesting study. There were four main parts to the user-centred design: understanding, envisionment, design, and evaluation. Interviewing users and scenario testing helped with understanding. Envisioning entailed testing different media to find the most suitable ways to communicate information. The design phase translated the information into prototypes. The evaluation phase used two types of user testing.
Abstract: OsloMet – Oslo Metropolitan University receives thousands of students and visitors annually. Its main campus consists of many buildings in which students, staff and visitors navigate. Unfortunately, navigating around the campus can be challenging, as the existing wayfinding system is complex and not straightforward. This paper presents a problem-based approach to address the wayfinding challenges around the campus. A group of European Project Semester students followed a user-centred design approach to involve participants throughout the four main phases of the study—understanding, envisionment, design and evaluation. Interviews and scenario-based user testing were conducted to identify the underlying problems. The findings indicated that the numbering system for rooms was inconsistent, and the signage was not clear, visible and coherent for all the buildings on the campus. Using graphic design principles and wayfinding guidelines, a new consistent room numbering, a signage system and a mobile navigation app were proposed, developed and evaluated. The results showed that the new wayfinding system was clear and easy to understand, and it can be applied in all buildings. We observed a shorter time spent navigating to a specific room, and no mistakes was made. The app was found to be a useful and helpful tool for wayfinding. As a result of this study, the authors highlight the importance of involving users throughout the entire research process, which is our most significant learning experience as a group.
The campus map in the top picture is the Parramatta South campus of Western Sydney University. It has several heritage buildings going back to the time of early settlement. Many new buildings continue to be added.
Airlines are working to improve accessibility, but airports also need to step up. People with disability are making regular complaints, and older people are likely to just give up travelling by air. Not good for the travel industry or tourism. So a well researched guide is welcome in this space. Wayfinding is far more than just good signage – it starts with the whole building design. In airports it’s about the customer experience and promoting independent travel. That’s regardless of age or ability.
Enhancing Airport Wayfinding for Aging Travelers and Persons with Disabilities is a comprehensive guide for wayfinding professionals, signage designers, and interior designers. It is published by the US Transportation Research Board’s Airport Cooperative Research Program. It comes with a checklist that emphasises community consultation as part of their universal design approach to wayfinding. The detailed guide also has a companion PowerPoint presentation that covers the key elements with lots of pictures. The presentation is 15MB and is downloadable from the main webpage and is a good way to get across the key points. There are eight chapters in the guide:
Understanding the needs of aging travelers and passengers with disability
Wayfinding strategies via visual, verbal and virtual communication
Airport planning and design consideration
Departing customer journey
Arriving customer journey
Connecting customer journey
Wayfinding technologies for aging travelers and persons with disability
To achieve the overall objective of helping aging travelers and persons with disabilities to travel independently, an airport has to consider more than just helping these customers know where to go.
Signalling the right way to go has to account for cognitive abilities, visual acuity, and spatial awareness. As people age some of these abilities decline. Consequently, considering the needs of this group in wayfinding design will make wayfinding easier for everyone. Mishler and Neider have identified five key points and explain them in detail in their article. They are:
Distinctiveness: the information should have cues that are informative to the route and can be distinguished from the surroundings.
Consistency and standardisation: information overload can be avoided with the consistent placement, size, colour and shape of signage.
Simplicity: limiting each sign to three or four units of information, because people tend to glance rather than read, and avoid visual clutter.
Isolation: keep the signs away from other visual clutter to help focus attention in the right place.
Reassurance: letting people know they are still on the correct route especially if the destination is a long way from the directional sign.
The title of the article is, “Improving Wayfinding for Older Users with Selective Attention Deficits”, in Ergonomics in Design. Here is part of their conclusion:
“Because maps and other layout information may not be easy for older adults to use, providing environmental support through wayfinding signage might be the best way to mitigate these difficulties. However, visual selective attention, which is needed to find and read a sign, declines in old age, which makes it particularly important to adhere strictly to certain guidelines for signage design.
Adhering closely to the principles of distinctiveness, consistency and standardization, simplicity, isolation, and reassurance should help not only to improve wayfinding performance for all users but also to reduce the performance gap between older and younger users.
Providing age-inclusive signage could help to maintain high mobility in older adults, prevent them from becoming isolated from their communities, and therefore help to avoid the mental and physical health issues that tend to be comorbid with age-related isolation. Age-inclusive signage design is therefore an increasingly important topic in an aging population.”
Wayfinding requires designers to organise and communicate the relationships of space in the environment. Basically, it is the naming and marking of places, identifying destinations, and providing directional information. The Cooperative Research Centre for Construction Innovation produced a comprehensive, if somewhat technical, set of guidelines for wayfinding.
The guide covers basic principles, and very detailed design solutions and strategies, covering topics such as arrival point, main entry, internal arrival point, graphic communication, restrooms and toilets, lifts, and signage design. Sign legibility, system design criteria, and viewing distance to signs are all covered, plus much more. Wayfinding is a key element of accessibility for everyone. Making signs and systems universally designed for everyone requires additional thought and planning.
Editor’s Note: I have come across a designer or two who consider signs and signage an imposition on their design and try to minimise their use or placement. This picture shows how one designer thought that disguising signage was a good idea.
Public displays are becoming more sophisticated, animated and dynamic, but are not often used for wayfinding. Three architecture researchers from University of Leuven in Belgium conducted an “in-the-wild” study at a railway station to test various display designs to see which would give the best wayfinding information.
The method and results are carefully documented with some interesting findings and conclusions. Graphics, charts and photographs add to the explanations and considerations for designers in the use of symbols, colours and spatial distributions.
Perhaps not surprisingly, they discovered that different people have different ways of seeing, using, and interpreting signage and wayfinding cues.
Abstract:Universal design is the design of products and environments to be usable by all people, to the greatest extent possible, without the need for adaptation or specialized design. Whereas this strategy is typically applied to broadly enhance usability of design—including its safety, accessibility, and simplicity—universal design can also be applied in a more focused manner to facilitate specific aspects of usability, such as wayfinding. In this chapter, the author describes not only what universal design is, but also what it is not: specialized designs to compensate for functional limitations. The chapter makes the case that specialized design, as embodied by the technical specifications in the Americans with Disabilities Act guidelines, defines a rigid set of prescriptive rules of what to do to promote safety and accessibility for specific individuals; universal design, as articulated by a set of performance guidelines embodied in the principles of universal design, describes how to promote usability and inclusivity—including community wayfinding—for everyone. Despite its potential, universal design has not been widely adopted as a strategy in promoting community wayfinding. The chapter addresses directions in research, policy, and practice necessary to promote universal design implementation.
