Make the difference by allowing your software to be easily accessible.

Availability of information has become one of our basic necessities in the modern world. But do we ask ourselves enough how we can offer full access to information to people with visual, cognitive, motor or hearing disorders? It is impossible nowadays to participate well in society without having the opportunity to receive the required information. More than 50% of the internet traffic in the world is via mobile devices. So the problem of availability of information for mobile services is very important. What does accessibility mean for the design of mobile applications and sites? What are the options for designers and developers to offer full access to mobile services, regardless of our physical capabilities?

Design for everyone

The basic principle for accessible design of mobile applications is to use common sense and common interest as guidelines. It’s pretty clear that any mobile service is a kind of real-life tool, or follows the real-life pattern. Almost every real-life action by a person with a disability takes much more time and effort than with others. That is why the principle of simplicity, clarity and intuition of the UI / UX design is particularly important.

To test this, you can perform a simple experiment. Imagine a lonely, blind person who dreams of finding his love. A simple desire of a person. Today, love is often found in the cloud, for example via the mobile application Tinder. A nice application, with a simple UI for most people, by swiping left-right, or the modern “she loves me, she doesn’t love me”. Now switch on the Voice-over mode and try to find it. This swipe function does not work. There are also no clear label buttons that can read Voice-over, so it is almost impossible to use the product. While today the same Voice can recognize the photo very well, and describe and read it to the lonely, blind person.

There are good examples of Accessibility. In EU countries, digital products from public authorities and companies must be accessible to all users, regardless of their capabilities. The Dutch Railways app has been designed and developed to meet these requirements. Each label is correctly signed on all application locations. With eyes closed you can plot and plan a route, hear information about a train, a station, delays, buy a ticket, etc.

Now back to our design principles for everyone. First of all, it is worth noting that four problem areas are mentioned in Accessibility: cognitive, visual, auditory and motor disorders. These disorders can be permanent (eg paralysis) or temporary (eg broken arm), congenital or acquired (impaired vision or shaking of the hand in the elderly).

Accessibility must first of all follow the most important principles:

Implementing Accessibility

Implementing Accessibility when designing your applications requires no significant effort. Below are a few basic principles that improve the availability of applications for people with disabilities.

All this does not lead to significant additional costs for development or testing. For many professional teams, this is a necessary part of every project.

Accessibility is important for applications with many users

In the spoken manuals from Google and Apple, the detailed principles of the correct Accessibility are clearly described. The most important task of designers and developers is to make technology accessible. The more technology is available to more people, the more likely it is to benefit from it all. The more the number of users of the product, the more important the support for disabled users.

For example, at the w3c consortium, the organization behind HTML, there are also many guidelines and tests about Accessibility.
