When it comes to mobile app development, many UX designers and software engineers overlook the importance of accessibility. Most applications are not tailored for people with some form of limitation. While many development teams see accessibility as a ''nice to have'' feature, it plays a critical role in today's mobile world. Building an EdTech mobile app with accessibility in mind can dramatically improve user experience and increase revenue.
Approximately 15% of the world's population suffers from some kind of restriction or violation. Apps for special education play an increasingly important role the our daily life of special education students and special education teachers. You should think that about one in seven of your users may not have the same level of access as other users of the app.
A common misconception is that accessibility is an optional feature when developing mobile apps. The Android and iOS platforms offer accessibility tools to developers to help them implement interfaces that work for all users (including those with disabilities or impairments). Obviously, it's not just people with disabilities who benefit from good UI and UX: voice assistants like Siri and Alexa have become very common, and tactile feedback (like vibration) is part of Google's Material Design guidelines. Some may want to use the app while driving or doing laundry without touching a mobile device.
In addition to moral considerations, you can expand your user base by making it more inclusive. From a business perspective, it makes sense to try to reach 15% of additional users. Last but not least, governments are beginning to implement laws and regulations that require equal access for all users. More on this later.
Since accessibility positively impacts applications, one might wonder why this is often overlooked. There are several reasons. Both Android and iOS have evolving ecosystems, which means all platforms are creating new accessibility features. Many assistive technologies are available for developers, but they are still under development. Even when they can be used, it often takes a lot of time and practice to implement accessibility features, and developers, let alone UX designers, often have no experience with them, making it difficult to design and test. Finally, unlike the Web Content Accessibility Guidelines (WCAG) for educational websites, there is no single document that defines accessibility standards for mobile applications.
I talked about the importance of accessibility, but what exactly does it mean? In simple terms, accessibility describes a way of developing educational products that are fully accessible to users with disabilities special needs students. These violations and restrictions can take many different forms, so I will describe those that are most relevant to EdTech mobile applications.
Users with any kind of visual impairment experience the greatest difficulty using a mobile application that is not suitable for them. Color blindness, low vision, or even complete blindness are the three main disorders. In the context of accessibility, sound, usually in the form of a screen reader, is often used to compensate for the lack of visual information.
Whether the user is deaf, has a mild hearing impairment, or has difficulty hearing in a certain range, there is always a way to realize a good user experience. Educational video and audio clips can be enhanced with additional text or titles.
Students with special needs may face problems navigating the EdTech mobile app. Touch or other forms of gestures should be customizable so that the user is not tied to a specific gesture. In addition, the motion should never be a required event, as physical restrictions should not interfere with navigation. Both Android and iOS offer users the ability to customize shortcuts for frequently used phrases or words, as well as the time between screen taps. The size of buttons (or other touch triggers in apps) is also configurable.
An often overlooked aspect of accessibility is accessibility for people with learning disabilities such as (functional) illiteracy and (functional) digital illiteracy. And this is not just a problem in developing countries: the Dutch government estimates that 1 in 9 citizens between the ages of 18 and 65 have difficulty reading and writing skills. The US National Center for Education Statistics found in a 2003 survey that 1 in 7 citizens had a prose literacy rate below baseline, and 1 in 5 had a quantitative literacy rate below the baseline. Special education apps can better serve these users by using simple, short sentences supported by clear, culturally recognizable iconography. Voice feedback is also an option.
Implementing accessibility solutions for any of the above constraints is insufficient to make the application accessible. Ideally, all aspects should be considered when designing and developing a mobile app, providing a good user experience for everyone.
''Accessibility allows us to harness the potential of everyone.'' — Debra Ruh
There is no dedicated person to implement accessibility into your product. This requires the involvement of the entire team:
UX / UI designers — design interfaces following accessibility guidelines.
Programmers — write the correct markup/layout of pages, make sure that all elements have the necessary tags and attributes.
Testers — conduct accessibility testing.
The main motivations for implementing accessibility are:
Empathy: We can minimize the barriers between users and content, thereby making their lives better. But, if you are not that sensitive and receptive, there are other quite compelling motivations.
Competitive Advantage: Increase in the percentage of satisfied users.
As I mentioned earlier, up to 15% of users have permanent, temporary or situational obstacles when interacting with the Internet. It doesn't matter what your company is focused on — websites, EdTech mobile or desktop applications and services — when you implement accessibility, you achieve an increase in the percentage of users who can successfully interact with your resource.
Among other things, accessibility is one of the modern trends in the IT world, the use of which improves the image of your company.
Law: A prerequisite for developing products for large international projects. In most EU countries, and in the UK, USA, Canada, Australia, Brazil, and India, accessibility standards are enshrined in legislation.
Now that we are familiar with the various obstacles, it is time to look for possible solutions to improve accessibility.
One of the most important aspects is consistency. Consistency is always a core UX principle, but it pays dividends for users with disabilities. For example, finding an illogical home button is much more difficult when you can't see the screen.
And it's not easy to have consistent experiences across different screens. You need the same experience with interfaces: be it sight, touch, or hearing, every user must be working with the same UX.
Buttons and URLs don't have to be directly related to your screen content. Instead, actions should be clearly labeled and separated from the text. Changing the text style (like underline/bold) should also clarify these points.
While we mentioned consistency earlier, it needs to be emphasized further when discussing navigation. Users with cognitive disabilities will benefit from a consistent and clear layout. Even completely blind users will immediately understand your layout if the mobile app adheres to either Google's Material Design Guidelines or Apple's Human Interface Guidelines.
The last crucial rule is to warn users when a navigation action exits the application. Users should never accidentally close your application.
It's important to remember that your mobile app can be viewed in different resolutions. Users can enlarge the picture up to 200%. Your application should be tested at different resolutions to give a good user experience.
Working with flowers is also important. There should be a clear contrast between the foreground and background. Placing light text on a white background or dark text on a black background will make the content difficult to read. The result may be unreadable for most users, and it will not be readable for people with visual impairments.
In terms of actual content and contrasting text, the font style of the text is also essential. While a fancy font might be appealing to some, it might not be readable to others. Be careful when using fonts that are italicized or difficult to read. If in doubt, please use the suggested (or default) font as referenced in the previously mentioned guides.
Images can also distract attention from user interaction when the app is not tailored for accessibility. It becomes even worse when images are not used for decoration but are meaningful. You must provide text descriptions for these images. These descriptions should describe in detail what is happening in the picture. They can also explain how a particular image relates to the text. However, there is no need to repeat what you already wrote before. This way, visually impaired users can get the same user experience as everyone else, as assistive apps for special needs education on their devices will be able to convert text to sound.
Duplicate phrases can confuse the user or look like a mistake. In short, decorative images (or images that do not contain any additional information) should be ignored by accessibility tools.
Video and audio content must also be adapted for accessibility. All media player controls must be accessible to anyone. For example, hearing-impaired users should be able to change the volume of the media being played. And for those who do not have enough volume, captions are necessary when the message is transmitted via video or audio.
To ensure quality, all professional software products must be thoroughly tested prior to deployment. The tester can check if all accessibility features are implemented correctly. However, if you want people with disabilities to have a good user experience, it is advisable to put together a group of beta testers with disabilities. Colleges, universities, or local organizations can help bring this group of testers together.
Limitations of mobility, vision, and hearing must be taken into account when developing web and mobile platforms for education. Many services and applications have already been developed that make life easier, which were impossible even yesterday. Let’s take a closer look at the best special education apps that can help you create really cool EdTech applications.
A service that, without exaggeration, can be called a genius. This application is for phones. The principle of operation is that a visually impaired or blind usercan direct the camera to the place where he wants to see something if he does not see something around. A sighted volunteer will tell him online what is where. The video on the site shows how a volunteer helps a blind person take an object from the table. Unfortunately, so far, the service works only in English.
The creators of this device asked themselves: "How can people with disabilities use familiar devices: a phone, a tablet?" Tecla allows people with limited upper-body mobility to access their smartphone or tablet using assistive devices. Let's say a person can only press one button; the device will help translate the pressing of one button into specific movements on the smartphone screen.
The Finger Reader allows blind and visually impaired people to read ordinary books. Putting on a finger a ring-like device equipped with a miniature video camera, the person runs his finger over the text. The device reads the text and speaks it out loud.
Let's take a look at the basic principles of inclusive design of EdTech application, or, as it is also called, universal design.
The basic concepts of accessibility apply to all (mobile) platforms. The choice of interface and design should make the software product available to everyone. However, each platform has its accessibility solutions. This section describes the main differences between the two major mobile platforms.
Screen readers are often used to convert text to speech to ensure that visually impaired or learning users have access to the same data. This way, users can hear rather than read the content. Screen readers are platform-dependent. Android offers Google Voice Assistant (formerly TalkBack), while iOS offers VoiceOver. Screen readers view the entire user interface as a component. Using gestures, you can navigate these components. Each component highlighted is read aloud. By default, the hierarchy of these components is based on left-to-right and top-to-bottom traversal. The gestures used for navigation are fairly similar across both platforms.
There are some important differences between Android and iOS regarding keyboards. For Android, users can operate with a Bluetooth keyboard for navigation. It's like navigating on a desktop computer. However, iOS cannot be controlled with the keyboard alone. VoiceOver must be enabled, resulting in some navigation restrictions compared to Android. Android even supports external braille keyboards when using the BrailleBack accessibility tool.
The EU is discussing ways to ensure accessibility through government regulation. The European Accessibility Act is a pending law aimed at improving the accessibility of services and products. Once this law is fully approved, the European Union will have three years to develop clear rules useful for people with disabilities.
Thus, offering everyone access to your product is not only an ethical task but also an opportunity to stay ahead of the competition in passing formal laws.
By designing your inclusive apps or apps for children with special needs, you can ensure a good user experience for all users. Affordability has a wide range of potential financial, moral, and legal benefits. The Android and iOS platforms offer various tools for incorporating accessibility features into your app. Basically, there is no reason to ignore the concept of accessibility.
Accessibility is not just a feature. This is a must for every mobile application. If you are interested in developing inclusive educational applications, fill out our contact form, and the team will be happy to create the most convenient application for different kinds of users.
