What are the Tools for Accessibility Testing for Mobile Application?

Accessibility testing services and tools

Mobile technology has gone beyond the scope of communication and has empowered areas like education, entertainment, finance, and much more. When it comes to app development, it is crucial to cover features and functionalities based on accessibility. 

Today, smartphones and mobile apps, in particular, have changed the way assistive technology is perceived. Advances in Accessibility Testing Services can be observed in many accessibility features for mobile devices. The WHO reports that around 15% of the global population has some form of special ability needs. Hence, accessibility testing is a crucial part of an app development process. 

So what is accessibility testing, what are the different types of accessibility categories, the key limitations and requirements, and the main tools which are used as part of the Accessibility Testing Services? Find out in this guide.

What is Accessibility Testing?

Accessibility Testing Services are conducted to ensure that a mobile app is suitable and usable for everyone including those who are specially-abled. So what does it involve? It is an assessment of the mobile app about how much of the content or services provided are accessible to those with special needs. It can involve evaluation of the simplest of design aspects like color schemes and font sizes to check whether they make it easy or difficult to access the content, features, and/or services. 

Users with different levels of abilities use an app accordingly. So there are different testing tools to ensure that an app is tested for accessibility at its optimal level. Such tools are also referred to as assistive tools.

Importance of Accessibility Testing Tools

Accessibility testing can help in uncovering design issues and bugs that may cause or contribute to poor UX for both general and specially-abled users. Studies show that around 20%  Americans and 17% Europeans have some form of special ability needs. Just 20% of these Americans have a stunning purchasing power of over $490 billion. So when it comes to developing apps, you cannot ignore this market.

There is another important factor at play here. 53% of millennials are serious about supporting companies and brands that invest in morals, values, and ethics. So when you ignore accessibility, you will be making a costly mistake. Both ethical and economic incentives make Accessibility Testing Services important for your app.

Categories of Special Abilities

The different levels of special abilities around which Accessibility Testing Services need to be designed are as follows:

Vision Impairment

All Accessibility Testing Services must use tools to check accessibility for users who are visually impaired. This can include color vision tools, Bluetooth keyboards, Screen Reader and single control keyboards. Some of the different sub-categories covered by such tools include the following:

Complete Blindness

There will be some users who are completely visually impaired. There are tools like Screen readers that can narrate the content on the application. It can narrate not just the content, but also the buttons, links, images, and other elements in the app. It will also narrate word-by-word anything you enter into a text box. 

When an app is poorly designed or developed, a Screen reader cannot narrate the content or elements correctly. This can mean inaccessibility for users who are visually impaired or have inability to see. 

Color Blindness

Accessibility Testing Services also need to test color blindness when testing apps. Color blindness refers to the inability to view certain colors properly. Blue and red are the most common colors that people with color blindness cannot see properly. So when someone with color blindness of red color uses an app that is more than 50% in red, they will not be comfortable using it. 

So an app needs to be designed in a way that even people with color blindness can use it without any accessibility issues. In the above example, if a button is red, it can be outlined with black to make it more accessible. Typically, black and white are treated as universal colors.

Poor Vision

Accessibility testing tools should also be able to cover accessibility by users with poor vision. This refers to users who do not have a clear vision or have a wide range of eyesight issues. Such users can have various problems with the retina. Apps can be designed to overcome poor vision challenge using the following strategies:

  • Avoiding small text. 
  • The content or features should be designed to be zoom-able. The layout should not break when the text or other design elements get zoomed.

Need for Vision Accessibility Tests

Digitalization has improved everyone’s life. Technology continues to play an important role in assisting people with special needs. It also provides them with opportunities to maintain a more independent life.

Accessibility in apps is essential and there is a growing need for apps that help the visually impaired. Both Android and iOS come with screen readers built-in to the devices supporting them. Screen readers can allow users with severe vision impairment and blindness to interact with mobile apps without even seeing.

Manual Testing Tools for Android

i. TalkBack Screen Reader

TalkBack provides 2 common methods of navigation:

  • Touch: Users can drag their finger on the screen and hear the content or control under their finger. Selection can be made with a double-tap anywhere.
  • Linear: Right or left swipe can help users navigate the screen elements in a sequence. Selection can be made with a double-tap anywhere.

ii. Color Inversion

This tool used by Accessibility Testing Services inverts all the colors to provide the high-contrast look. It is suited for users with low vision and color blindness.

iii. Color Correction

This tool is used for testing accessibility for users with color blindness. It allows different mode settings including the following:

    • Deuteranomaly for Red and Green color blindness
    • Tritanomaly for Blue and Yellow color blindness
    • Protanomaly for Red and Green color blindness

Manual Testing Tools for iOS

i. VoiceOver

This tool works as a screen reader for visually impaired users. It can read buttons, links, icons, and other UI elements. Users can use gestures for selecting or navigating.

ii. Invert Colors

This tool allows users to choose between Smart Invert and Classic Invert options. Smart Invert inverts all colors except those of images and certain media. The Classic Invert option inverts the color of all the elements. This tool is ideal for those with low vision.

iii. Color Filters

This tool allows users with different types of color blindness to access apps more easily. The different color filter options include Grayscale, Green/Red filter, Red/Green filter, and Blue/Yellow filter.

Hearing Impairment

When it comes to Accessibility Testing Services for mobile apps, users with hearing impairment should also be taken into account. There are different levels of special hearing needs, ranging from minor loss of hearing to complete deafness. While more than a million Americans are considered to be functionally hearing impaired, around 50 million suffer from one or the other type of tinnitus. 

There are different levels of hearing disability intensity, so different strategies need to be implemented to make an app accessible. 

So what should the Accessibility Testing Services be looking for when using their tools to test an app.

i. Accurate Captions

  • Captions allow hearing impaired users to follow dialogues or action on the app
  • Captions need to be accurate and have non-speech elements

ii. Transcripts

A transcript helps users with special hearing needs to follow and consume content in a different way. Transcripts should be used along with captions and not replace them.

iii. Multiple Contact Modes

Since hearing impaired users cannot use the general mode of communication using a mobile device, they need alternate methods. These can include email, apps like Skype or other methods.

iv. Clear Audio

  • High-quality audio makes accurate captions easier
  • The tools will check audio for clarity, which can be beneficial for users who having special hearing needs

v. Simple Yet Clear Language

Accessibility Testing Services also use tools that test apps for the use of simple and clear language. Some of the features which are checked in this regard are as follows:

  • The use of jargon or slang
  • Content structuring using headings/sub-headings
  • Use of consistent language
  • Use of active voice

The American Sign Language (ASL) is not the same as English Sign Language. It is important to make the content and elements simple and clear for users that follow either English or ASL.

Learning Disability

Accessibility testing tools should also test apps for users with learning disabilities. It is estimated that around 20% of people in the world have learning disabilities associated with reading, writing, and/or spelling. 

  • Reading/Writing Accessibility: Users with dyslexia can find it difficult to read and write and your app must be designed to accommodate them. 
  • Color/Design Format: The display options play an important role in accessibility of apps. Complex UI and layouts make it even difficult for users with such special needs. 

Accessibility tools will test apps to ensure suitable contrast, darker colored text, and lighting options. The UI is tested for any unnecessary text.

Apple’s guidelines for UI design have contributed to the simplification of mobile app usability concepts. It is important to keep assistive technology in mind when designing mobile apps. This helps in simplifying your users’ learning capabilities.

Restricted Motion

When designing and developing your app, you should keep in mind not just the users who can tap and access its features. You should also design it keeping mind users with limited motion abilities. This can include users who cannot use their hands. Accessibility Testing Services will test apps for voice access or control and other input methods.

The following steps or features are expected to make an app accessible for users with restricted motion or reduced mobility:

  • Users should be able to use alternative input methods
  • If the app uses path-based/multipoint gestures, they should also be usable with a single point or without any complex gestures
  • If intentional movements are required to cause action, there should be the option to disable the motion and use alternative methods to take the action

Some of the different types of accessibility capabilities that an ideal app should have include the following:

  • Voice Recognition: To convert spoken words into text, to be used as input.
  • Screen Reader: To read the text on the screen.
  • Screen Magnification: To enlarge the content and make it easier to read for vision-impaired users.

Special Keyboard: To make it easy for users with motor control difficulties to type.

Accessibility Testing Tools

i. Switch Access

This accessibility testing tool allows users to interact with the device using switches in place of the touchscreen. It is suited for users having dexterity or motor impairments and prevents the need to interact directly with the device. The different types of switches include an external switch, external keyboard, or buttons on the mobile device.

_________________________________________________________________________

ii. Voice Access

This tool is designed for users who have significant motor impairments. It allows users to control the device using spoken words. Users can use your voice to navigate, open applications, edit text, and do more without using hands.

iii. Switch Control

This tool allows the use of switches for various UI functions such as selection, tap, dragging, typing, and freehand drawing. The users have to use a switch to select something on the display. The switch can then be used for selecting an action. It is designed for iOS platform and makes accessibility simpler for users with mobility limitations.

iv. Voice Control

This iOS Accessibility Testing Services tool can be sued for navigating and interacting with the device using voice. Voice commands can be used in place of swipe, tap, type, and other actions. It can also be used for locking screen and is suited for users with motor impairment.

More Accessibility Testing Tools

Besides these tools, a wide range of extensions can also be used for accessibility testing. Some of the examples include the following:

  • Axe for Android: This is a comprehensive Accessibility Suite with features like View Hierarchy and Automated Eventing Stream analysis. 
  • UBK Accessibility Kit: It aids with accessibility development/testing. Audit your iOS app and avoid the need for stopping and inspect each element using Xcode.
  • A11y Ally: It allows you to discover accessibility issues in a passive manner.
  • Accessibility Inspector: It shows action methods, information properties, and position related to the object under the pointer.
  • Accessibility Scanner: This Android-based tool makes suggestions for accessibility improvements.

Even when the app development environment is improving, there are still apps that create the void of inaccessibility for users with different levels of hearing impairment and other special needs. The incorporation of multimedia sharing and video call features has benefited such users. But the development environment still has a long way to go to ensure that users with all kinds of special needs get covered. Yet these accessibility testing tools make the task of Accessibility Testing Services much easier and faster.

 

Understanding the Importance of WCAG Compliance Testing in Accessibility

Understanding the Importance of WCAG Compliance Testing in Accessibility

Importance of WCAG Compliance Testing in Accessibility

15% of the world’s population is constrained by some disability (visual, hearing, motor, cognitive), which makes it nearly 1 billion people in sheer numbers. 

Digital accessibility is herein imperative in ensuring this section of the population is able to access digital solutions without any impediments.  A plethora of digital platforms and websites today lack accessibility features, which makes it very difficult or nearly impossible for this special section of the society to access them like a normal user would.

A website built with mobile or web accessibility not only gives benefits to the user base including the people with disabilities, but also delivers an overall improved user experience. 

What is WCAG Compliance?

The Web Content Accessibility Guidelines (WCAG) is a set of technical specifications that one needs to adhere to while working on improving or incorporating digital accessibility. The compliance aims to improve the accessibility of mobile applications, web applications, web content and websites on all digital devices. The mission is to provide an equal experience to people with disabilities (neurological, physical, auditory, speech, vision etc.). To achieve this, it thus mandatory to run every product through comprehensive WCAG compliance testing or accessibility testing.

The guidelines for WCAG are constructed by a global community of accessibility experts who form the W3C (World Wide Web Consortium). The objective is to make the internet as inclusive as possible.

The WCAG compliance guidelines are largely meant for WCAG testing engineers, web content developers and all other related professionals. This checklist is a practical resource guide for accessibility professionals. The first part is a primer of industry nomenclature and

accessibility testing approaches. Fillable and printable checklists follow.

Relevance of WCAG 2.1

It has been almost a decade since the inception of WCAG 2.0 (2008). It has a total of 12 guidelines divided under 4 basic principles – P.O.U.R. (Perceivable, Operable, Understandable and Robust). Each of these guidelines has a list of criteria that needs to be satisfied while making content (text, audio, images, code and markup) accessible. The 3 levels of conformity in WCAG are:

  • A (minimum accessibility)
  • AA (solution to common accessibility issues)
  • AAA (maximum or the highest standard of accessibility)

WCAG 2.1 (2018) does not cancel or make WCAG 2.0 obsolete; Both of them are ‘currently existing’ accessibility standards. WCAG 2.1 is backward compatible and includes 17 additional success criteria for mobile accessibility including the existing 61 from WCAG 2.0 as seen below.

LevelWCAG 2.0WCAG 2.1Total
A25530
AA13720
AAA231528
611778

While there isn’t complete visibility into the future, all organizations following WCAG 2.0 / 2.1 and conformance to level AA must continue adherence to the accessibility laws including Section 508 of the Rehabilitation act, Americans with Disabilities Act (ADA) and the Accessibility for Ontarians with Disabilities Act (AODA).

Additions in WCAG 2.1 compliance for mobile applications

While performing WCAG compliance testing for mobile applications the accessibility engineers need to follow both 2.0 and 2.1 guidelines. These include:

  • Speech input (character key shortcuts & name label)
  • Device settings (Orientation)
  • Pointer (gestures, size of the target, cancellation of the pointer)
  • Input methods (motion actuation, concurrent input mechanism)

Apart from these mentioned above, other standards such as content on hover, reflow, non-text contrast, text spacing and identifying input purpose can also be applied for mobile app accessibility testing.

Automation in accessibility testing

The industry offers a plethora of automation tools for testing specific components of a website, app experience, mobile device experience or any similar document. The accessibility experts leverage various automation tools to effectively test the product and understand how and why people with disabilities might face problems. The best approach suggested is a combination of automated testing and comprehensive manual testing.

Manual and functional testing

Manual and functional testing is an integral part of the overall accessibility testing process. The human testing expertise becomes inevitable while checking the automated tests and having pair testing teams (Combination of sighted and non-sighted engineer) is even more valuable in determining digital nuances. To ensure compliance and usability, QA teams leverage several tools that help with:

  • Code validation
  • Document accessibility
  • Mobile accessibility
  • Web accessibility
  • Colour contrast and colour blindness

Accessibility is evolving to be a very important engineering attribute today in differentiating a product from the rest. Its importance is aligned both with user experiences/needs and legal requirements globally, all of which speak of the growing user base for this solution. Accessibility as an industry is also evolving with newer standards and guidelines. More automation is coming into the forefront, in an area which has traditionally been handled manually. 

At QA InfoTech for example, we have a newly developed automation toolbar for accessibility, WCAT, that enables us determine accessibility compliance with certainty, compared to tools in the market today. Stakeholder buy-in for accessibility, a strong engineering strategy, the right team (preferably a paired team of SMEs and differently abled users), balanced choice of tools, constant connect with the industry to understand evolving guidelines and technologies, together with partnerships with specialized vendors will go a long way in your digital accessibility journey.

Mobile Accessibility – More Possible Now Than Ever Before

Mobile Accessibility – More Possible Now Than Ever Before

Premise to Mobile Accessibility:

Globally today there is a lot of sensitization and awareness for accessibility in the digital solutions that are engineered and physical products and spaces that are built. While this is encouraging and standards and compliances are being accepted globally, there wasn’t a lot of specific focus on mobile accessibility for a long time. Engineering for mobile accessibility largely relied on web application accessibility standards. However, this has changed in the last year, thanks to the revision in WCAG, which is now available as WCAG 2.1, since June 2018. Of the several success criteria that this recent version recommends, one set primarily focuses on mobile accessibility. Why is this important now than ever before?

We have always been aware that close to 15% of the world’s population lives with some form of disability or another. Specific to mobile, a recent study of close to five hundred Android applications, shows us that 95% of them have accessibility violations, 98% have potential violations and 66% have warnings. This is a significant number that cannot be ignored. Also most have issues around the common accessibility issues at the GUI level or one layer beneath at the semantic level. Issues herein largely include, focus related problems, missing element descriptions, text to color ratios, spacing between elements, font and element sizes. These are all easy to fix accessibility issues, which when taken care of, improve the accessibility scores, quite significantly.

The New Success Criteria in WCAG 2.1

Looking at the core success criteria in WCAG 2.1 specific to mobile accessibility, it is largely around screen orientation and input modalities. Criteria around pointer gestures, pointer cancellation, label in name, motion actuation and support for varied orientations have been introduced keeping mobile accessibility in mind. Herein all kinds of impairments have been taken into consideration to ensure the mobile application is accessible in all scenarios.

Pointer gestures for example talks about how just swipe or pinch actions should not be the only ways to perform specific actions. Pointer cancellation deals with how pointers should be cancellable once invoked. Label in name, is a very easy to implement criteria to ensure the visual text label matches the programmatic ARIA label, making it easy for screen reader users to perceive what’s on the application. As much sophistication and flexibility specific motion actions bring in, it is important to engineer them such that users can disable them when needed and the same functionality is achievable even when they are disabled. This is similar to ensuring the entire application is accessibility via keyboard only access. The criteria also talks about the need to ensure the application is equally visible and accessible on both portrait and landscape modes.

Automation in Accessibility Engineering

Clearly as new success criteria evolve, design and engineering teams need to be savvy and up to date to implement them in the apps they develop, even if it means re-engineering them. And to be able to do these, newer assistive tools become important. For example, deep learning based speech recognition tools are helping mobile accessibility engineering efforts significantly. It is a combination of new success criteria and such tools that have together made mobile accessibility a reality today.

More Resources:

Additionally, thanks to evolving technology test automation in accessibility is possible today than in the past. This has been a very human centric space in engineering requiring manual efforts especially on the quality front. We at QA InfoTech have been able to leverage AI, machine learning, open APIs such as openCV to be able to automate complex areas. Services providers will have to continue to build an edge to be able to test for domains that are increasingly leveraging the latest in technology – for example this blog talks about digital accessibility in the travel domain. QA WCAT is a tool that we have developed in-house, to use for our clients, to gauge accessibility implementation maturity, more reliably than current market tools such as Axe and Wave.

We had a good webinar recently covering all of the above with examples and demos – the full recording from the session is available on our webinars page (visit the page for this, other past and upcoming webinars) and also here.

Improve the Customer’s Online Experience with Digital Quality Assurance

Improve the Customer’s Online Experience with Digital Quality Assurance

Let’s understand quality – ‘The benchmark of excellence’, which may be high, low, good or bad, depending upon how we address it with respect to the subject being addressed to. Applying these concepts on the development and testing of a mobile or web app would mean ‘a certain degree of value’ which in this case would mean ‘bug free to a large extent’, ‘do as assigned’ or ‘a degree of stability’ when we talk with reference to the user.

The approximate revenue generated worldwide in 2019 from mobile app amounts to approximately USD$ 462 Bn. The figure clearly indicates that the revenue game is huge and anyone not being an active part of the same is definitely losing out in the game.

So, what could make you a bigger player? The answer is very simple – Trust & Assurance, of the company, of the client, of the consumer, of the brand and more. This means higher the assurance level, greater is the impact and bigger is the revenue generated. That brings us to Quality Assurance.

Comprehensive Quality Assurance Services helps clients get a constant quality product across channels, operations, platforms and businesses. The quality assurance platform effectively uses a combination of several other rigorous testing services such as DevOps practices, Automation Services, Cloud testing and more to help build a digital reputation and an easy digital transformation journey with elevated customer experience. It combines principles of process re-engineering with machine learning, cognitive computing and artificial intelligence, to boost the efficiency of the test authoring process and its execution.

With continuous disruption in the software testing industry and amid the proliferation of the evolving digital technologies, quality assurance testing services must be taken at topmost priority. With new apps and software being launched every minute in the hyper-connected digital industry today, customer experience has been shifted to a challenging position, with respect to the quality and reliability of the app. It demands comprehensive quality and digital assurance services to accelerate and rekindle the same.

The global E-Learning market is all set to hit USD$ 325 Bn mark. The figure clearly marks the effective intervention of technology in the field of education. With mobile based applications being omnipresent in the field of education, its use in delivering the teaching and learning material is discreetly known as E-Learning. This form of education is quite prominent in universities and significantly differs from the conventional form of education. With quality assurance and digital accessibility services creating a blended form of E-Learning, it can thus seamlessly mix with technology and traditional learning methods.

With increased level of awareness in the education sector these quality services make sure that the app caters to what it is meant for, i.e monitoring the performance, demonstrating outputs and an efficient workflow. Various researches show that the success of these E-Learning apps depend upon a number of factors such as:

  • Accessibility of the resources
  • Functionality of the app
  • Engagement level
  • Scope and flexibility of learning

Embracing Accessibility in Agile Development

Embracing Accessibility in Agile Development

Accessibility in Agile Development

Inaccessibility in today’s digital world can attract expensive lawsuits and damage your brand exponentially. Several countries have enforced legislation to incorporate digital accessibility in solution engineered therein.

Digital accessibility drives to enable software and website inclusion to the widest range of audiences possible. WCAG 2.1 guidelines have made it imperative for organizations to enforce accessibility effectively in digital products and services, especially in the US. For want of individual standards in several countries, Section 508 and WCAG have almost become global guidelines except in places such as in Europe where DDA is prevalent

Accessibility is often perceived as a unique feature. However, it is more spread around interaction and presentation. Developers are expected to implement WCAG 2.1 guidelines while keeping all the stakeholders in the loop.

For instance, visually impaired people need an alternative for image intensive websites. In short, they need a simple description in plain text which can be easily read by the screen reader.

Accessibility Testing from the Start

The common question that prevails is when to start accessibility testing? While accessibility takes full shape once the HTMLs are implemented, there are several other things that can be started in advance.

For instance, testers can start with checking distinct descriptive page titles and consistency in the hierarchy of headlines. Testing links and form fields can also be started. More importantly, tester’s can get involved upfront in validating the design and implementation considerations including collaborating with developers on what it takes to engineer for accessibility. This helps in a product of much better quality released to test.

Leveraging Automation

Several accessibility features can be tested in an automated manner during agile development including APIs, UI and code units among others. Just like grammar scanners and syntax in document editors, you can also check the syntax of HTML and JavaScript to ensure accessibility patterns are present as per the requirement. Free versions and paid versions of these checkers are available online. You can incorporate some of them into your continuous integration model as well.

However, it comes with a caution. Syntax checker might report that the presence or absence of an alt txt but not whether it is right or not. This is where QA InfoTech brings in an automated advantage using Artificial Intelligence, where we have automated the checks and engineering for alt text using image recognition and natural language processing capabilities. While this is still evolving, the importance of manual verification here by real users on the team cannot be underestimated.

Manual Testing

After efficient implementation of the UI; capable manual testing can only enforce the right evaluation from the end-user’s perspective. The process includes thorough checking for contrast and colours, assistive tool usage, text implementations amongst others.
Testers can also conduct this process during the prototyping phase to determine invisible spots after the final inspection. One can also leverage text analyzers to calculate the readability and complexity index of the content on the web page. Testers can get the use perspectives by using screen reading tools. All these should be considered during accessibility testing in agile development.

Tracking

Identified barriers during accessibility testing should be documented with all other defects, in a similar manner as functional defects giving all the required details.

While any kind of bug can hamper the user experience the same is not true for people with disabilities. An issue which may be ok to live with for regular users, may be a tough one for the differently-abled. Hence, it is essential to keep the specific user group in mind while testing the features.

While testing it is also important to consider the level of severity to identify whether something can be rectified with a simple workaround or would require users to guess, restart, retry, look for assistance, go through several steps etc. Testers need to identify whether the issue is permanently hampering the user experience. It is also crucial to identify whether the issue is acting as a blocking element disabling the user from further using the application.

Accessibility Testing Checklist

It is an efficient practice to collate the checklist of every minute accessibility aspect to evaluate the web page easily. Here are a few points which should be considered during accessibility testing in agile development. VPAT and the guidelines defined in WCAG are also a good starting point herein:

  • Keyboard Operations
  • Assistive Tools’ Functioning
  • Visual Testing through Screen Reader
  • Font and Foreground: Background Colour Testing
  • Image Testing
  • Text Magnification Testing
  • Visual ARI Testing
  • CSS Testing
  • Automated Testing

Accessible Reading

Ensuring that the content of the page is readable through screen reader is an important part of accessibility testing. “Accessible reading” testing involves checking the page’s readability score and ensuring that the screen reader is able to pronounce everything visible on the page with the right context.

Accessible Navigation

User-friendly navigation is the backbone of any successful application. A user-friendly navigation will allow users to easily move from one UI element to another, click buttons, links or input data efficiently.

Testers should analyze each and every UI control through keyboard only option to evaluate for accessibility. Access the content while keeping in mind that accessible reading and workflow should be linear and traceable from left to right throughout the lines.

Herein check for visibility levels as well to ensure all application’s features are visible and readable.

Paired Testing Approach

Adopting paired testing approach can help testers in achieving better results. Testers should sit with a differently abled person while testing the software or website. The differently-abled person can give a real picture about how difficult or accessible the software is to use.

Paired testing approach can also help in faster identification and fixing of accessibility challenges. It also leads to better understanding of how differently abled people function and react to the software.

While accessibility is still not a global mandate, adding the goodness of inclusion to products and services can reap immense benefits. Today’s user base has become diverse due to easy access to smartphones. Smartphone users are easily able to use web from anywhere and at anytime. Besides, it should become the moral responsibility for organizations to provide highly accessible applications to differently abled people.
