How to Conduct Accessibility Testing on Android Devices?

As per recent research by World Health Organization, roughly 15% of the worldwide population is ‘specially-abled’ in some form or another. Developers creating a mobile application for all, need to analyze this 15% is a potential population opportunity that can be catered well. Other than creating dedicated applications for differently-abled people, making sure the current applications are disabled-friendly is a moral responsibility for every developer to ensure all its users are able to access their application with ease.

To accelerate this process, innovative tools are used to check if the applications are functioning as per Web Content Accessibility Guidelines or WCAG. This is where accessibility testing comes into the picture. Accessibility testing helps identify errors in software and functions incorporated in your systems and mobile phones to ensure that an application is accessible to people with disabilities, including visual, auditory, physical, speech, cognitive, language, learning, and neurological disabilities.

We’ll know about these tools and their functions in detail but first, let’s understand more about accessibility testing and what all disabilities can be catered to by adding a few features to your existing applications.

Top 6 Benefits of Usability Testing


What is Accessibility Testing?

A subset of usability testing, Accessibility Testing can be defined as a kind of software testing service performed to ensure that the application being tested is accessible by people with physical disabilities like hearing, color blindness, old age, and other groups.

There are special assistive technologies incorporated in systems and mobile devices for people with such impaired disabilities. This helps them operate the software being used with ease.

There are four different kinds of software typically being used to increase accessibility in devices:

  • Speech Recognition – It converts the spoken word to text, which can be replaced by normal typing
  • Screen Reader– This will read out the text that is written on the screen.
  • Screen Magnifier- This helps enlarge the text on the screen for vision-impaired people.
  • Special Keyboard these are special keyboards designed for people having difficulty in typing.


Why is it Necessary to Conduct Accessibility Testing?


Reason 1: Cater to a Wider Market for Disabled People

As per a recent study by the World Bank, over one billion people, or 15% of the world’s population, experience some form of disability, and it’s higher for developing countries. One-fifth of the estimated global total, or between 110 million and 190 million people, experience significant disabilities in some form or another. The less significant ones in this category include blindness, deaf, handicapped or other physical disorders.

To be honest, 15% is a huge market that can be catered to by software product developers with ease. A little extra effort can be put in to make this software suitable for this population.


Reason 2: Avoid Discrimination and Legal Complications

Government agencies have promoted IT product developers to make their products disability-friendly. They have come up with various legalizations like:

  • Americans with Disabilities Act – 1990 in the United States
  • Disability Discrimination Act – 1995 in the United Kingdom
  • Disability Discrimination Act – 1992 in Australia
  • Disability Act of 2005 in Ireland

Making sure you include this step of Accessibility Testing in your product development cycle ensures all these legal compliances are checked and helps you avoid being filed for lawsuits in the future. A lot of companies in the past have been sued for not having disability-friendly products, for example, the NFB Vs AOL settlement case of 1999.


Reason 3: Provide better Search Engine Optimization

Though accessibility compliance is more of a concern for developers and coding professionals, the SEO specialist also has a major role to play to make sure your applications or websites are SEO friendly and easily accessible and usable to all.

Broadly three areas need our attention here: Alt text, contrasting text, and empty links. Ignoring these elements can lead to detectable WCAG failures and ultimately fail in accessibility testing.

Depending on the type of disability, you can use various tools to test your applications. The most common disabilities are vision and hearing disorders mentioned below-

1) Vision Disability and Visual Impairment

ImpactQA - Accessibility Scanner Vision disability is for those who are either blind or have partial vision impairment. The tool being used here is a ‘Screen Reader’.

A screen reader is software that reads out aloud the content on your mobile screens. It narrates everything from menus, to descriptions, to navigations. The most common Screen Reader available for developers is JAWS for windows computers.

For visual impairments, there are two different types: color blindness and poor vision.

Colour blindness is a state in which a person is unable to view some specific colors. The website graphics must be designed in a matter to help people with color blindness access your website with ease. Having black border lines around your images can help them differentiate shapes and sizes on screen.

Poor vision, on the other hand, is when you need your text to be large or have better graphics so that while enlarging the image doesn’t break for the reader.

2) Other Disability

User with Hearing Disability (Deaf or hard to listen): Easy Alt text or alternative text should be available for those having a hearing disability for them to be able to access the content being presented on the website.


How to Perform Accessibility Testing?

There are three basic ways to perform accessibility testing:

  • Accessibility Scanner
  • Manual Testing
  • Automated Testing Tools

Accessibility Scanner

Manual Testing

Manual testing can be done easily, using your own mobile applications.

Go to Settings→ Accessibility → TalkBack → and tab it on.

Using this, the user can interact with their Android device without seeing the screen and observe any potential errors in the process while using it.

There are two ways to navigate your applications using TalkBack:

  • Linear Navigation
  • Explore by touch

Switch Access:

This application allows you to interact with your application using a switch instead of a touch screen. There are various switches sold in the market that can be used by people with motor impairments. Examples include AbleNet, Enabling Devices, RJ Cooper, etc.
