A study to depict challenges and opportunities building industry professionals face when designing inclusive and accessible buildings

Inclusive Design has been widely promoted in the fields of product, engineering, and user experience design. Despite the educational efforts made by scientists, practitioners, and institutions to raise awareness about accessibility and inclusion, Inclusive Design has not been widely embraced in architectural design practice, where it is often associated with design for disability. This multidisciplinary study, spanning behavioural science, ergonomics, and the social sciences of architecture, explores the challenges architectural design practitioners face when designing inclusively, and identifies opportunities to promote the adoption of Inclusive Design. The results of a questionnaire completed by 114 architectural design practitioners underscore the lack of client awareness of the benefits of inclusive design, highlight the important role practitioners can play in advocating for Inclusive Design, and emphasize the need to develop practices and tools that enhance the design and post-design phases of buildings to ensure inclusion, diversity, equity, and accessibility.

Inclusive design in electrical stimulation technologies and neurorehabilitation for clinician and patient end users

Dr. Tamsyn Street is an interdisciplinary researcher working for the National Health Service (NHS) in the UK with a background in motor neurorehabilitation. In the last couple of decades there has been a rapid advancement in assistive technology solutions using electrical stimulation for neurorehabilitation. This editorial examines whether these advancements have translated into good inclusive design performance for clinician and patient end users. Suggestions for overcoming some of the existing challenges are proposed.

Developing Innovative Solutions for Universal Design in Healthcare and Other Sectors

For over half a century, researchers have sought to better understand the needs of people with disabilities in the built environment, and for more than a quarter century, they have sought to understand the effectiveness of universal design (UD) on a wide range of people and populations. This research led to the creation of the innovative solutions for Universal Design (isUD) building certification program, which addresses knowledge gaps in the practitioner's field with UD criteria. The isUD focuses on commercial buildings but aims to expand to other sectors including healthcare and residential settings. The research and outcomes used in the development and evaluation of the isUD combined with lessons learned from implementation of the isUD program suggest a path forward to improve and expand the program. Several research studies have evaluated the effectiveness of UD standards. One study compared university residence halls, one of which was built using a draft version of UD standards using a guided tour and online surveys among other methods.[1] Another study used online surveys to compare a workplace built using the isUD with the former workspace.[2] Another study used in-person surveys to compare public right-of-way features pre- and post- design intervention.[3] Lastly, an innovative doctoral dissertation that proposes a new methodological tool to evaluate UD in healthcare settings [4-5] has been analyzed to inform the isUD's expansion into the healthcare sector. The results indicate there is value in using UD to address equal access to and use of facilities for people with and without disabilities, and people of diverse social, cultural, and economic backgrounds. Facilities built using UD standards and tools are more usable, comfortable, and satisfying for users. However, the results also indicate there is room for improvement to make the isUD tool more effective. These improvements will better enable expansion of the tool to be usable in settings with more specialized requirements. While UD is often effective at improving human performance, health and wellness, and social participation across some measures, and while tools that assist with UD implementation may further help achieve these outcomes, to gain widespread adoption across multiple sectors, such tools must be shown to be consistently effective in achieving UD outcomes across all measures. These improvements can help expand availability of UD to a wider, more diverse audience.

A Pattern Language for Inclusive Design: A Set of Patterns for Designing Reusable Accessible Solutions

A common cause for inconsistent accessibility in the design of ICT applications is that designers work to develop optimal and satisfactory interfaces but they do not take care to comply with all users' needs and possibilities to access. The study presented in this paper stems from a lack of published evidence able to support designs in developing accessible interfaces for websites, mobile apps or conversational Interfaces (chatbot or voicebot). This work aims at investigating accessible design patterns that can be used by designers to implement applications accessible by multiple devices. To solve this problem, we propose a design pattern language able to provide WCAG compliant design out-of-the-box solutions. The navigation through the design patterns allows designers to gather existing solutions based on solid evidence and examples to develop inclusive applications accessible by web, mobile devices or conversational agents.

Evaluation Methodology for Inclusive Schools Environments. A Comparative Analysis Towards Goals and Strategies for Urban Design

The paper deals with the issue of social inclusion in the scholastic environment where children begin to learn the set of rules that manage social life. The design of the spaces impact on people and becomes crucial to address a community behavioural change in terms of social inclusion. In line with Universal Design strategy, the paper presents a method developed for evaluating the degree of inclusion of primary schools' spaces, which consists of the definition of an evaluation matrix. The matrix makes possible to analyse quantitative-qualitative characteristics for each school and compare them objectively. It asses the level of accessibility and inclusion of the schools through four main categories (Outdoor space, Orientation, Movement, Spatial quality) and related criteria and indicators. The reliability of the evaluation matrix has been verified through its application in seven case studies (Italian and EU), and the analysis of one of them is described in the results. The present study proposes a basis to introduce a method able to support designing educational spaces that satisfy the needs of a wide range of users according to Universal Design strategy.

The experiences, needs and barriers of people with impairments related to usability and accessibility of digital health solutions, levels of involvement in the design process and strategies for participatory and universal design: a scoping review

Objective

Globally, the number of digital health solutions is increasing, but they are not always designed with access and utilisation for people with impairments in mind. Development efforts have often not included the voice and requirements of people with impairments, who make up 15% of the world’s population, despite the fact that this can help ensure broad access and utilisation. Little attention to and limited inclusion of people with impairments in the development of digital health solutions results in continued and reinforced inequalities in health services provision for people with impairments. This review investigates the needs and barriers of people with impairments related to use of digital health solutions and strategies to foster user participation, access and utilisation of digital health solutions.

Methods

This scoping review, based on the Joanna Briggs Institute Manual, had five phases: 1) identification of aim and research questions, 2) literature search in five databases (April/May 2020), 3) literature screening based on predetermined inclusion and exclusion criteria, 4) data extraction, and (5) reporting results.

Results

The literature search resulted in 5968 sources, of which 25 met our inclusion criteria. People with impairments appreciate digital health solutions that are designed to meet their specific impairment-related challenges. The reported needs and barriers related to technological design varied depending on the individuals’ challenges. The literature reported different types of participatory co-design strategies to foster access and utilisation of digital health solutions.

Conclusion

This scoping review support needs for increased awareness among developers to design solutions that meet people’s needs, contexts and states of health. By applying universal design as a strategy and including people with different types of impairments, starting in the idea creation phase of digital health solutions and throughout the development, developers can design solutions with better accessibility. Digital health solutions that are accessible and usable have a tremendous opportunity to foster health equity and achieve health promotion, prevention and self-care. This in turn can contribute to closing the gap between different population groups, reduce disparities and get the most from available healthcare services.

Housing design that improves the independence and safety for older adults using a walker

Globally, the walker is one of the most common assistive technologies used by older adults with mobility impairments, which is also the case in New Zealand. However, there is a scarcity of knowledge regarding their specific requirements in housing design. Adopting an ethnographic approach, the perceptions and spatial use of 16 older adults who used a walker were investigated as part of a larger study on quality of life and housing design. Five emergent themes for walker user perception and spatial use were identified, from which design considerations were distilled and then categorised into 10 design elements. The study highlights differences between the requirements for accommodating walkers and those for accommodating wheelchair users. It provides new insights into improved housing design for older adults, which have the potential to be incorporated into existing frameworks for accessible design and universal design thereby improving the independence and safety of older adults.

Multisensory inclusive design with sensory substitution

Sensory substitution techniques are perceptual and cognitive phenomena used to represent one sensory form with an alternative. Current applications of sensory substitution techniques are typically focused on the development of assistive technologies whereby visually impaired users can acquire visual information via auditory and tactile cross-modal feedback. But despite their evident success in scientific research and furthering theory development in cognition, sensory substitution techniques have not yet gained widespread adoption within sensory-impaired populations. Here we argue that shifting the focus from assistive to mainstream applications may resolve some of the current issues regarding the use of sensory substitution devices to improve outcomes for those with disabilities. This article provides a tutorial guide on how to use research into multisensory processing and sensory substitution techniques from the cognitive sciences to design new inclusive cross-modal displays. A greater focus on developing inclusive mainstream applications could lead to innovative technologies that could be enjoyed by every person.

An integrated literature review of the current discourse around universal design in the built environment - is occupation the missing link?

PURPOSE

To synthesise current literature regarding applications of universal design (UD) to built environments that promote social participation, identify areas of agreement and areas requiring further attention and development. Occupations refer to personally meaningful activities, which people need, want or must do as part of their daily life.

MATERIALS AND METHODS

Recently published literature (January 2011-December 2017) relevant to UD and built environments, and pertaining to any discipline or professional area, were identified via a systematic search of databases in the EbscoHOST platform. The person-environment-occupation (PEO) model was chosen as a theoretical framework for the review, which included a sample of 33 peer reviewed journal articles.

RESULTS

The current discourse is driven more by description, discussion, and commentary than empirical approaches; although, a combination of quantitative, qualitative, and mixed methods approaches was employed. Much of the current discourse on UD and the built environment focuses on the person and the environment, with the occupations carried out in built environments and the interaction between these domains not referred to in much detail.

CONCLUSIONS

Including occupations, social participation, multi- and trans-disciplinary collaboration, and multicultural perspectives in the ongoing discourse around UD would enable the concept to reach its full potential as a medium for social justice. Implications for Rehabilitation The universal design (UD) process must account for the occupations that people perform in the built environment. Multi-disciplinary research and development, using multiple methods, is the most appropriate approach to investigate the application of UD to the built environment. Key areas of contention within the current discourse include meaningful inclusion of non-professional stakeholders, tensions between embracing and eliminating diversity and how professional education should be delivered.

Designs for Flies + of Mice and Men: Design Approaches to Drosophila melanogaster

Designs for Flies is an award-winning design-led interdisciplinary project between KYOTO Design Lab (D-Lab), the Department of Applied Biology at the Kyoto Institute of Technology (KIT) and Charcot-Marie-Tooth (CMT), Japan. Within the framework of speculative design yet using an inclusive methodology, Frank Kolkman, a young Dutch designer, took Professor Masamitsu Yamaguchi's climbing assay experiment with Drosophila in his genetic mapping for CMT as the point of departure. Kolkman sought to address two questions raised during his initial research: "Could alternative strategies be used to generate interest from pharmaceutical companies for obscure, complicated or 'unmarketable' diseases in drug research?" and "Could transgenic Drosophila be used for the wildcard testing of drug compounds directly by patients at home in the search for a possible cure?" The chapter will describe its genesis, design process and the challenges and potential of interdisciplinary projects of this nature along with the impact of the resulting concept, which incorporated service, system, product and interaction design. It won the Services and Systems category of the Dutch Design Awards (DDW) in 2016, and Kolkman was named DDW's Young Designer of the Year in October 2017. It was followed by Of Flies, Mice and Men: drosophila and the interconnected landscape of genes, a Drosophila-related science communication project by Marcel Helmer, Kolkman's successor as D-Lab Design Associate for which the design brief was based on issues raised by the first project. This is also described to highlight the differing issues, design approaches and results of this science/design collaboration.

Insights on the apparel needs and limitations for athletes with disabilities: The design of wheelchair rugby sports-wear

Wheelchair rugby is a sport that has been gaining popularity with athletes with disabilities. However, as it is relatively new and not played by the masses, market specific sports-wear is not available for this sport, which impacts directly on performance and clothing satisfaction of the athletes. Therefore, the main objective of this research was to identify the problems that wheelchair rugby players face with the sports-wear they use for playing the game. The data was collected using a focus group and a questionnaire with 61 wheelchair rugby players in the United Kingdom. Based on their suggestions, on the team expertise, and on the literature, a set of design recommendations was proposed for the upper body garments (tops), lower body garments (bottoms), and gloves. The results demonstrated that the gloves currently available negatively impact on players' ability to participate with satisfactory levels of protection and comfort. Moreover, tops and bottoms also present issues, mainly in the fit and ability to regulate the core body temperature. Hence, the recommendations proposed can provide designers with key information on the specific sports-wear requirements and allow them to design and develop products that can satisfy real needs of specific end-users. This paper intends to raise awareness of the needs of sports-wear for those playing wheelchair rugby and promote the inclusivity of athletes with disabilities.

Bringing Human Diversity into Design Processes Through Empathic Modelling

Most products are developed while adapting to requirements from industrial production and logistics. To break that trend and design for people, we suggest focusing on those who put the strongest demands on the final solution. They cannot compensate for bad design solutions and are thereby, like sniffing dogs, guiding designers to meet peoples' needs. We always use a combination of empathic modelling and involvement of people with reduced functions to find new solutions to the problems a product is supposed to solve. We have used this method in the teaching of Universal design at different universities for more than ten years. The students find the exercises to be a very entertaining eye-opener leading to development of empathy for human diversity all while the level of innovation in their design work increase. To constantly make design students understand barriers that can occur due to bad design solutions we utilize a toolbox simulating different kinds of functional ability. It also includes a handbook that describes workshops, evaluation methods and design processes that can be performed using the tools. The goal is to guide efficient, innovative and inclusive design processes. By simulating diversity among people, the designer can interpret the needs of different users and use that as a starting point and for evaluating design solutions during the creative process.

A case for inclusive design: Analyzing the needs of those who frequent Taiwan's urban parks

Taiwan's declining birthrate has resulted in an aging population, and the needs addressed by public facilities are changing along with the shifting population structure. Visitors to urban parks filled out 869 questionnaires on the topic of inclusive design. Structural equation modeling revealed that park patrons could be categorized as those with special needs, and the general public. The biggest difference between these two groups manifests in their disparate needs concerning outdoor primary service facilities, followed by facilities related to accessibility, automation and the functions performed in open areas. Difficulty with autonomous access was identified as the leading cause of exclusion. Based on the autonomous access principle, three inclusive needs levels were identified: safety (high priority), accessibility (moderately-high), and regular maintenance (average). Inclusive design in public parks aims to equalize usage by all sectors of society.

Differences in vision performance in different scenarios and implications for design

To design accessibly, designers need good, relevant population data on visual abilities. However, currently available data often focuses on clinical vision measures that are not entirely relevant to everyday product use. This paper presents data from a pilot survey of 362 participants in the UK, covering a range of vision measures of particular relevance to product design. The results from the different measures are compared, and recommendations are given for relative text sizes to use in different situations. The results indicate that text needs to be 17-18% larger for comfortable rather than perceived threshold viewing, and a further 20% larger when users are expected to wear their everyday vision setup rather than specific reading aids.

Design for All in Scandinavia - a strong concept

Design for All is more than an appealing point of view. It is a concept that offers a set of challenges capable of generating innovation and giving design added value and weight. In the Scandinavian tradition, the concept has developed from a purely social dimension to a design topic that is discussed both in terms of its business potential and in relation to Corporate Social Responsibility, CSR. This article gives a State of the Art of the development of Design for All in the Scandinavian countries: Denmark, Norway, Sweden and Finland during the past 15 years, beginning with a common review and joint Scandinavian projects, followed by an overall review country by country which include selected case studies over the past 15 years.

Developing inclusive design expertise within a client/consultancy relationship

TheAlloy have been working together with British Telecom (BT), as their product design consultants, for over ten years. During that time BT have undergone a key transformation which has had a profound impact on their design focus. This transformation has seen BT actively embrace inclusive design as a core driver for their business objectives. As part of that journey, TheAlloy have in turn developed core competencies which have not only supported BT's transition, but impacted the consultancy's ability to offer these services to other clients. This paper reflects on the development of that relationship and those competencies through a series of project case studies.

The unique achievements of Japanese industries in the super-aged society

Considerations are made on how successes were brought about, what can be learned as well as what issues should be addressed in the future.

Interdisciplinary engagement with inclusive design - the Challenge Workshops model

The DBA Inclusive Design Challenge and the Challenge Workshops organised by the lead author has exposed numerous design teams to the benefit of working with extreme users - this paper will analyse the challenges and benefits of this approach to inclusive design and suggest how the lessons learned from competition can be transferred into design practice.

BT's adoption of customer centric design

Between 2005 and 2010 BT underwent a major transformation from a company with a special section devoted to 'older and disabled consumers' to a company with an inclusive design strategy. The mainstreaming of these issues responded to a demand for better, more user-friendly communications products and growing awareness of the importance of previously marginalised consumer groups. It also took place alongside the development and publication of BS7000-6, a guide to inclusive design management. Based on several product design case studies, this paper reflects on how and why this transformation was seen as necessary for future success, and how the transformation was achieved. The evolution of BT's approach has continued since, but this paper looks back in time, and documents the transformation up to 2010 and reflects the state of the company in 2010 rather than at the time of publication.

A framework for collecting inclusive design data for the UK population

Successful inclusive product design requires knowledge about the capabilities, needs and aspirations of potential users and should cater for the different scenarios in which people will use products, systems and services. This should include: the individual at home; in the workplace; for businesses, and for products in these contexts. It needs to reflect the development of theory, tools and techniques as research moves on. And it must also to draw in wider psychological, social, and economic considerations in order to gain a more accurate understanding of users' interactions with products and technology. However, recent research suggests that although a number of national disability surveys have been carried out, no such knowledge currently exists as information to support the design of products, systems and services for heterogeneous users. This paper outlines the strategy behind specific inclusive design research that is aimed at creating the foundations for measuring inclusion in product designs. A key outcome of this future research will be specifying and operationalising capability, and psychological, social and economic context measures for inclusive design. This paper proposes a framework for capturing such information, describes an early pilot study, and makes recommendations for better practice.

Design and evaluation: end users, user datasets and personas

Understanding the needs and aspirations of a suitable range of users during the product design process is an extremely difficult task. Methods such as ethnographic studies can be used to gain a better understanding of users needs, but they are inherently time consuming and expensive. The time pressures that are evident in the work performed by design consultancies often make these techniques impractical. This paper contains a discussion about the use of 'personas', a method used by designers to overcome these issues. Personas are descriptive models of archetypal users derived from user research. The discussion focuses on two case studies, the first of which examines the use of personas in the car design process. The second examines the use of personas in the field of 'inclusive design', as demonstrated by the HADRIAN system. These case studies exemplify the benefits 'data rich' personas contribute as opposed to 'assumption based' personas.

A comparison of methods currently used in inclusive design

Inclusive design has unique challenges because it aims to improve usability for a wide range of users. This typically includes people with lower levels of ability, as well as mainstream users. This paper examines the effectiveness of two methods that are used in inclusive design: user trials and exclusion calculations (an inclusive design inspection method). A study examined three autoinjectors using both methods (n=30 for the user trials). The usability issues identified by each method are compared and the effectiveness of the methods is discussed. The study found that each method identified different kinds of issues, all of which are important for inclusive design. We therefore conclude that a combination of methods should be used in inclusive design rather than relying on a single method. Recommendations are also given for how the individual methods can be used more effectively in this context.
