Computing students show age and gender bias

As we know, bias sits in all of us whether we realise it or not. Some biases we are aware of, such as liking certain people and things. But what about those biases we are not aware of that sit silently in the background of our thoughts and ideas? And how much do they impact on the things we say and do? Age and gender bias has an impact on how things are designed.

Older people are thought less likely to use desktops, laptops and smartphones, and to have less expertise with them. Women, both young and old, are thought to have some experience with devices, but less expertise than men.

A group of researchers in Austria wanted to find out the perceptions of computing science students about age and gender. That’s because they are going to be designing the digital technology in the future. In a nutshell, they found several biases.

Age and gender bias

Students (aged around 21 years) started to see people as old at the average age of 57 years – several years younger than their grandparents. Older people are thought to be less likely to have experience with all types of devices. While younger people are thought to want aesthetic designs, older people are thought to need error tolerant systems.

The bias between the genders was smaller than that of age. Women were seen as less likely to use a desktop than men and to have less expertise than men overall. This fits the continuing stereotype that computing for men is ordinary, and exceptional for women. Consequently, older women were seen as less capable in using computers and laptops.

The article has a lot of statistical analysis, but the key points are in the findings, discussion and conclusions. The information is useful for teachers, and the authors recommend designing with users as a way to overcome bias. And, of course, more women should be encouraged into the computing sciences.

The title of the study is, How Age and Gender Affect the Opinions of Computing Students Regarding Computer Usage and Design Needs.

From the abstract

This study aimed to understand the perceptions of young computing science students about women and older people about computer literacy and how this may affect the design of computer-based systems. Based on photos, participants were asked how likely the person would be to use desktop computers, laptops and smartphones. And also, how much expertise they thought they would have with each technology. We asked what design aspects would be important and whether they thought an adapted technology would be required.

The results draw on 200 questionnaires from students in the first year of their Information and Communications Technology (ICT) studies at an Austrian university of applied sciences. Quantitative methods were used to determine if perceptions varied significantly based on the age and gender of the people depicted.

Qualitative analysis was used to evaluate the design aspects mentioned. The results show that there are biases against both older people and women with respect to their perceived expertise with computers. This is also reflected in the design aspects thought to be important for the different cohorts. This is crucial as future systems will be designed by the participants. Their biases may influence whether future systems meet the needs and wishes of all groups or increase the digital divide.

Gender and Mobile Apps

An academic paper, A Study of Gender Discussions in Mobile Apps, provides some insights into gender bias in app development.

From the abstract

Mobile software apps are one of the digital technologies that our modern life heavily depends on. A key issue in the development of apps is how to design gender-inclusive apps. Apps that do not consider gender inclusion, diversity, and equality in their design can create barriers for their diverse users.

There have been some efforts to develop gender-inclusive apps, but a lack of understanding of user perspectives on gender may prevent app developers and owners from identifying issues related to gender and proposing solutions for improvement.

Users express many different opinions about apps in their reviews, from sharing their experiences, and reporting bugs, to requesting new features. In this study, we aim at unpacking gender discussions about apps from the user perspective by analysing app reviews.

We first develop and evaluate several Machine Learning (ML) and Deep Learning (DL) classifiers that automatically detect gender reviews. We apply our ML and DL classifiers on a manually constructed dataset of 1,440 app reviews from the Google App Store, composing 620 gender reviews and 820 non-gender reviews.

Our best classifier achieves an F1-score of 90.77%. Second, our qualitative analysis of a randomly selected 388 out of 620 gender reviews shows that gender discussions in app reviews revolve around six topics: App Features, Appearance, Content, Company Policy and Censorship, Advertisement, and Community. Finally, we provide some practical implications and recommendations for developing gender-inclusive apps.

Manual for Streets 2

Motor vehicles have dominated road design and road rules for most of the last century. With public policy promoting walking and wheeling this has to change. With this in mind, the UK Government’s Manual for Streets 2 gives pedestrians a higher priority on streets and roads. It builds on the original manual published in 2007 with a wider application of the principles.

Research carried out in the preparation of Manual for Streets 2 indicated that many of the criteria routinely applied in street design are based on questionable or outdated practice.

Street patterns last for decades so we have to get them right for the future.

Manual for Streets 2

The Manual for Streets 2 begins with a rationale and principles. Photographs and case studies illustrate the design ideas. The main body of the document covers design principles and detailed design issues. It includes:

  • Street networks, and connectivity
  • Community involvement
  • Pedestrian needs
  • Cycle facilities
  • Bus facilities
  • Junctions, crossings, access
  • Traffic signs
  • Parking and street furniture

The likelihood of walking goes beyond a level, uninterrupted footway. It is influenced by the quality of the walking experience and how safe people feel. Design that accommodates the needs of children and people with disability will suit all users. this includes easy ways to cross the street in their line of travel.

The Manual advises that there should be little need for dedicated cycle lanes, but doesn’t advise sharing space with pedestrians. Rather, the aim is to create conditions on the carriageway so that cyclists are content to use it. Nevertheless, where there is high traffic volume and larger vehicles, cycle lanes, or combined cycle/bus lanes will be required.

Manual for Streets 2 is a companion to the original Manual for Streets published in 2007, which has a handy 8 page summary document. Although it is a UK publication, much is transferrable to Australian conditions.

A school and a library join up

This is a story from regional Australia where joined up thinking maximised the social and economic benefits for the whole community. Both the school and the library facilities needed an upgrade. So here was an opportunity to develop a ‘joint use’ community hub to service the town and to support lifelong learning in the community. However, the project, underpinned by universal design, had its challenges.

David Tordoff and Julia Atkins discuss the project and its challenges in a book chapter. The title is Developing a School and Community Learning Hub: A Case Study from Regional Australia.

Understanding the place and the community who will use the facility was a key pillar in the success of the project. A strong shared vision and clear identification of needs led to the development of a highly integrated, adaptable facility that will respond to school and community needs. Photo from the book chapter

The New South Wales Department of Education generally encourages schools to engage in shared use of school facilities. The school controls the facility and allows community use out of school hours. However, this is not as effective as it could be due to governance barriers.

The overarching project design guidelines included universal design principles along with the UN Sustainable Development Goals. Project specific design principles were developed to embrace life long learning, celebrating art and multicultural heritage, and embedding universal design principles.

The chapter explains the issues, the processes, connection to land, place, history and people. Consultation with the Wiradjuri community had a significant impact on the design, artefacts, and the naming of places. Images help with explaining the concepts.

Policies and protocols

No matter how well the built environment is designed, they way the place and space is used by people can still raise problems. For example, spaces designed for quiet activities will only work well if users keep quiet. Likewise, spaces designed for collaboration do not suddenly give people the ability to collaborate.

This project paves the way for other communities to create community hubs within and adjacent to school grounds. With several stakeholders, a collaborative approach is needed to negotiate the way through governance issues.

An interesting book chapter for designers, local government, community groups, school staff, and library staff. It’s open access.

Architects and occupational therapists collaborate

When the built environment is poorly designed from a user perspective, it limits what people can do if they have a disability. On the other hand, if it is designed well, people can continue to do everyday tasks more easily and for longer. Collaboration between occupational therapists and architects is not new. However, there are barriers to interprofessional experiences that limit universal design solutions.

Architects having a preference for autonomy is one barrier. Differences in terminology, lack of understanding of each profession’s skill set and scope of practice is another.

A conference poster captures the essence of a study on improving collaboration between occupational therapists and architects. The aim is to improve universal design in new homes and community buildings. The title of the poster is Collaboration between Occupational Therapists and Architects to Incorporate Universal Design to Increase Accessibility.

Beyond compliance with occupational therapists

Accessible built environment advisors and practitioners know that it’s an uphill battle to get clients to go beyond compliance. However, if the client agrees, it might be time to go beyond compliance with occupational therapists. 

Occupational therapists (OTs) and universal design have much in common, say James Lenker and Brittany Perez. In their paper they argue the case for including the skills and knowledge of OTs across the spectrum of design disciplines and in research activities. Inter-disciplinary collaboration is the key.

The title of the Lenker and Perez article is, The role of occupational therapists in universal design research. This three page paper is easy to read and promotes the importance of collaboration for the best universal design outcomes.

OTs are involved in home modifications, but rarely considered in the public domain. They hold key information about how our minds and bodies interact with the built environment. So they can sometimes bring new solutions to the table with universal design.

Guide for OTs on universal design

Apeksha Gohil has devised a universal design guide for OTs. The aim of the guide is for OT practitioners to offer universal design solutions. The guide is a three stage stepwise process to reach universal design solutions beyond compliance and prescriptive standards.

Gohil agrees that stakeholders are primarily interested in what is required by the law. However, it is important to create awareness about user participation and co-design a part of the design process. One of the aims of the guide is to create awareness about role of OTs in universal design and create best practice examples. 

The Universal Design Consultation Guide for Occupational Therapy Practitioners is structured as a step by step guide. The document is available on ResearchGate, or you can download directly as a PDF document. 

You can also find out more from Elizabeth Ainsworth and Desleigh de Jonge about the relevance and application of universal design in occupational therapy practice on the ResearchGate website. 

Older people and the smart city

The term “smart city” refers to the way local authorities use digital information to make planning decisions and create solutions. But is this linked to the real lives of older people and the notion of age-friendly cities? According to UBANAGE, a European project, not enough data is collected on people aged over 65 years.

Time to develop smart city technologies that account for older people so that policymakers can inform their decision-making with evidence from older people.

Three older women are sitting on a public seat overlooking some housing in the distance. Older people and smart cities.

Researchers found current data sets inadequate for analysis of older populations. One of the reasons is the need for the privacy of personal data. Here we see the dangers of trying to develop algorithms and simulation to solve problems. This is where co-creation enters the picture. Older adults, public servants and other stakeholders worked together to test solutions for addressing the needs of older people.

The title of the research paper is, Older people and the smart city – Developing inclusive practices to protect and serve a vulnerable population. The term “vulnerable” is overused in relation to older people and feeds into stereotypes. Many older people are still active in the workforce and no more vulnerable than younger cohorts.

What is a “Smart City”?

What is a smart city and is it different from other cities? Smart cities use digital technology and data to improve decision-making and quality of life. The aim is to gain a better understanding of current conditions and forecast future changes. The data are also used to improve city functions and create solutions. But how does it work?

More is explained in an article titled, Smart City Design Principles. For a city, town or community to become smart it needs connected technology. Smartphones, sensors and Internet of Things devices connect to the Internet and each other and share the data they collect with city staff. Managers use various applications to take this data and turn it into information they can use. This can have a huge impact on urban development and planning.

There are four key elements:

  1. Quality encompasses liveability, environment, and quality of life (which should include accessibility and inclusion).
  2. Residential Construction focuses on addressing the needs of current generations without negatively impacting future generations.
  3. Capacity is about natural and human resources – population distribution, water, etc.
  4. History and Environment is about achieving cohesive regional development, traditional practices and archaeological zones. 

Anyone interested in understanding and applying the elements of the smart cities framework will find the article useful.

Abstract

A smart city should embrace the concept of sustainable growth, as it is an urgent need, and we cannot hesitate in coping with precious natural resources and plunge into crisis.

To make the city run as a smart city, several things should be included in the situation. In the long term, smart city visions that are inclusive, pluralistic, and citizen-centric, focused on developing services and resolving local challenges, would be the most effective and cost-efficient.

They are most likely to avoid potential issues by strengthening both physical facilities and amenities, as well as the city’s sense of culture.

Population ageing and smart cities

An article in The Conversation challenges the idea that older people are a problem and a burden. Apart from being an ageist proposition, it does little to change matters. When we talk of “empowering older adults” to engage in active ageing, who took the power away in the first place? Was it the advent of secluded congregate living that seduced older adults into feeling “secure”? Or was it something else? Regardless, research continues on ways to make people “feel capable and safe”. 

The article in The Conversation begins with older people “need help and encouragement to remain active as they age in their own communities.” It is not clear why this is specific to older people. The article continues to explain how a city can provide digital infrastructure for the local information older people need. Three solutions are proposed for keeping older adults, indeed everyone, active and healthy:

  • Replace ageism with agency for improved quality of life.
  • Connect to smart city data to get the right information.
  • Include co-design in planning for greater participation and inclusion.

A previous post on Ageing in neighbourhood rather than retirement villages reports a similar approach to population ageing. 

Age friendly cities toolkit

The World Health Organization has updated their resources on age-friendly cities and communities and added a toolkit. In 2007 the Age Friendly Cities and Communities (AFCC) program was rolled out. A Global Network of Age-Friendly Cities followed in 2010. The strength of the program was an early form of co-design with older people in local communities. That is, it promoted a bottom-up process with top-down policy support.

The guide has suggestions for meaningful engagement of older people in creating age-friendly environments. It includes detailed examples of existing national AFCC programmes, and practical steps for creating or strengthening such a programme. The vision is for all countries to establish a national AFCC programme by the end of the UN Decade of Healthy Ageing (2021–2030).

The toolkit is a separate set of resources to the guide.

The glossary lists all the words and labels used for older people and is a useful resource in itself. As with many official guides there are a lot of words and explanations about the history and ideas. The eight domains of action are the same as the 2007 version of the guide. The Framework for implementing national programmes is in section 3.

You can access all the relevant documents and information on the WHO’s National programmes for age-friendly cities and communities web page. If you want the free toolkit you will need to sign up to get it.

A Global Network of Age Friendly Cities

There are more than 1400 members of the Global Network, and looks like it will continue to grow. The network acts locally to encourage full participation by older people in community life and active ageing. The program is an important step in meeting the goal of the UN Decade of Healthy Ageing. Setting the scene for improved participation by older people benefits everyone. What’s good for older people is good for all people.

The Age Friendly Cities and Communities program puts older people at the centre and covers all aspects of life. It’s where policy meets people. The vision is that older people can transform themselves by transforming the environments in which they live, work and play.

Good colour contrast for websites

How did you choose the colours for your last website update? Did you choose colours based on your brand logo and text or did you use the Web Content Accessibility Guidelines (WCAG) algorithm? But can the WCAG algorithm guarantee good legible colour contrasts for websites? Research by The University of Cambridge says it doesn’t. So they have developed an alternative algorithm for good colour contrast for websites. 

Five different coloured ovals with both black and white text for comparison. Human perception is better for good colour contrast for websites.
Examples of black and white text for comparison

Since January 2022, the Accessible Perceptual Contrast Algorithm proposes that legibility of text on websites is better with perceived difference than a mathematical contrast ratio. White text on strong coloured backgrounds are preferred over black text in almost all cases in the study. 

In the examples above, the black text passes the WCAG contrast ratio but fails the white text. The Accessible Perceptual Contrast Algorithm passes the white text and fails the black text. 

Sam Waller explains this more fully in his article, Does the contrast ratio actually predict the legibility of website text? 

As a result of this work, an early working draft of WCAG 3 proposes using the new method for calculating contrast. 

This is important information for choosing brand logos and text so it isn’t just something web designers should know. Many website designs are guided by brand colours so choose carefully. This information is also important for product labelling especially for online shopping. 

 

Livable Housing Handbook

The Livable Housing Design Standard applies to all new Class 1a and Class 2 buildings. Class 1a buildings are detached houses, row houses, terraces, townhouses and villa units. Class 2 buildings are apartment buildings and the design requirements apply inside the apartment. Public access requirements cover the public areas. To aid practitioners, the Australian Building Codes Board has produced a Livable Housing Handbook.

The Livable Housing Design Standard sets out minimum requirements for mainstream dwellings.

Front cover of the Livable Housing Design Standard showing a single storey home with garage.

The title, ‘Livable Housing Design’ comes from Livable Housing Australia’s voluntary guidelines. The features in these guidelines form the basis of the mandatory requirements, which are similar to Livable Housing Australia’s ‘silver level’.

The Livable Housing Design Handbook aims to help practitioners understand the relevant sections of the building code. These are Part G7 of NCC Volume One, Part H8 of NCC Volume Two, and the ABCB Standard for Livable Housing Design.

The Handbook covers design issues in generic terms and does not provide specific compliance advice. It aims to assist practitioners develop solutions to comply with the NCC requirements.

The intent of livable housing design is “to ensure that housing is designed to meet the needs of the community, including older people and those with a mobility-related disability.”

Front cover of Livable Housing Design Handbook.

The appendices have examples of bathroom layouts and a guide for meeting compliance with the NCC.

Going beyond the Livable Housing standard

The Australian Building Codes Board has also produced a guide for going beyond the minimum standard. The voluntary standard is generally based on Livable Housing Australia’s “Gold level”. These features provide a greater level of livability across the lifespan for more people, and go beyond the “silver level”. Consequently, exceeding the minimum mandatory requirements will still achieve compliance.

This additional set of non-mandatory technical provisions will better meet the needs of the community. They are similar to the Gold level in the original voluntary Livable Housing Design Guidelines.

Front cover of Livable Housing Design Beyond Minimum Standards guide

Australian homes are some of the largest in the world and the features in the voluntary standard should not be difficult to achieve.

Extensions and major renovations to existing homes will be based on state or territory requirements to comply with the standard. For example, if the works require a council development application.

Online learning – Livable Housing Design

CUDA has acquired the licence from the Australian Building Codes Board to run their course on Livable Housing Design Standard. The course is based on the Handbook and the Standard. This is a technical course for home-building professionals. Find out more about this course. and all the different ways to achieve a level entry.

The long road to Livable Housing

And the journey isn’t over yet. While the Livable Housing Standard is now in the national code, it is up to each state and territory to implement it. Victoria, Queensland, Tasmania, ACT and Northern Territory have agreed to implementation. South Australia has come late to the party but is now working on an implementation strategy.

Australian Network for Universal Housing Design (ANUHD) has been leading the charge for the reforms for twenty years. They believe that Western Australia could also sign up to implement the standard eventually. However, as of September 2023, NSW remains uncommitted. The livable housing story of citizen advocacy is documented in a conference paper.

Universally designed dream home

Not your average home. This one goes beyond even enhanced standards in the Livable Housing Design Standard. The video is from O’Shea and Sons Builders and shows what can be done with creative thinking. While this is a top-end of the market home, all the features are possible in mainstream homes. As Nick O’Shea says, “… an absolutely amazing home where functionality and style means absolute beauty.”

Co-designing with people living with dementia

A diagnosis of dementia used to mean staying home and being cared for. Those who work in the area of dementia are doing their best to change this view. But is the design community prepared to embrace people living with dementia? Paul Rogers reports in Co-designing with people living with dementia disruptive design interventions to break the cycle of well-formed opinions and mindsets. The co-design method has provided ways for people with dementia to continue contributing to society and have fulfilling lives.

The co-design project was to create a new tartan design. Each person with dementia directed the researcher to co-create their digital design one colour at a time.

A tartan from the research paper with orange and green colouring. Co-designing with people with dementia.

The paper describes the process in detail. The Disrupting Dementia tartan project shows how co-design methods and tools can enable people living with dementia to make a significant contribution to society after diagnosis. Although dementia changes some aspects of a person, it does not affect their sense of self. Projects such as these not only inform designers, they also give a sense of inclusion and belonging to people with dementia.

From the abstract

This paper illustrates methods for co-designing with people living with dementia in developing a mass-produced product. The research was carried out in collaboration with Alzheimer Scotland using a range of disruptive design interventions. The aim was to break the cycle of we-formed opinions, mindsets, and ways-of-doing that remain unchallenged. The research has resulted in co-designed interventions to help change the perception of dementia.

People living with dementia can offer much to UK society after diagnosis. Co-designed activities and interventions help reconnect people recently diagnosed with dementia to help build their self-esteem, identity and dignity. Co-design processes help keep people with dementia connected to their community, thus delaying the need for formal support,

We worked collaboratively with over 130 people with dementia across Scotland in the co-design and development of a new tartan. The paper concludes with recommendations for researchers when co-designing with people living with dementia.

Altering design mindsets

Breaking Well-Formed Opinions and Mindsets by Designing with People Living with Dementia is a similar paper. You will need institutional access for a free read, or access via ResearchGate.

The paper reports on three design interventions using co-design activities with people diagnosed with dementia. The interventions offer innovations for co-designing with this group.

Singapore’s Long-Term Plan

Singapore’s rapid urban development didn’t happen without a plan – indeed, it took several integrated plans. The aim of Singapore’s Long-Term Plan is for liveable and sustainable homes and built environments for residents. It’s basically a land use and infrastructure plan with a 50 year view. The broad ideas in the plan are translated into Master Plans with detail about land use and density.

Given geographical constraints, Singapore has adopted innovative solutions to achieve a high standard of living for residents.

Singapore’s Liveability Framework

A conference paper by Koh and Lee explains how the Singapore Liveability Framework has brought liveability, sustainability and prosperity. Developing state-owned land comes with government conditions. Consequently, developments are aligned with the Liveability Framework and master plans. Universal design is considered in all built environment plans.

Housing for All

In 1960 there was an acute housing shortage. In five years they built 50,000 flats to solve the shortage. Then they turned towards providing better housing to meet the aspirations of the population for a better quality of life. Singapore encourages home ownership and supports occupants to purchase their government owned flats.

Planning for Mixed-Use

Public housing is not excluded from prime locations and is mixed with retail, commercial and residential zones. Mixed use developments are also found as part of integrated transport hubs. The integration of mixed-use districts starts at the planning stage and encourages innovative development concepts.

Planning for Polycentricity

Decentralisation is key to being able to live, work and play without the need to travel long distances. Each regional centre has industrial estates, business parks, and educational institutions. At a more detailed level there are schools and shops and a transport node.

Connectivity and Walkability

Roads and expressways take up 12% of the land. Consequently, similarly to other countries, plans are prioritising public transport, walking and cycling, and extending the rail network. Better first and last mile connectivity is a must. Covered linkways connect transportation with residential areas to make walking more comfortable in the tropical weather. Repurposing roads for pedestrian space is also part of the plan.

Convenient access to green and blue

Singapore is more than a concrete jungle. The idea of a garden city began in 1967 as part of transforming Singapore into a clean and green haven for tourists and investors. Of course, residents benefit too.

A city for all ages

Life expectancy has risen by 20 years in the last 60 years and the population is therefore ageing. One in four Singaporeans will be older than 65 years by 2030. While there are various options for older residents, the government has introduced new public housing concepts. Co-location of housing with healthcare facilities, retail and dining areas, and community gardens is one solution. Community Care Apartments are another idea where residents can live independently with support services.

Living in a disrupted world

The conference paper is long and detailed with many case studies and photographs. Having government control over development and developers means strategies are implemented according to the plans. Climate change and COVID are now part of life and Singapore has to move beyond liveability and sustainability to build resilience.

The title of the paper is, Strategies for Liveable and Sustainable Cities: The Singapore Experience. It’s open access from The Palgrave Encyclopedia of Urban and Regional Futures.
