Today, 1.3 billion people, that is, 16% of the world’s population, live with a significant disability. Faced with this reality, accessibility is no longer just an ethical choice but has become a regulatory requirement in many countries: it represents a driver of inclusion, a regulatory imperative, and a growth opportunity for businesses.
Disability takes many forms. Some are visible, such as motor or visual impairments, but nearly 80% of disabilities are invisible. These include cognitive disorders, color blindness, hearing impairments, epilepsy, and even temporary limitations (a broken arm, fatigue, aging, etc.).
Digital accessibility involves designing interfaces that all users can understand, navigate, and use, regardless of their physical, sensory, or cognitive abilities.
Completing a simple task online can be a real challenge for some individuals. Here are the main obstacles and best practices to address them :
Visual impairment
| Challenges | Solutions |
| Blind or visually impaired people use screen readers and rely on content structure. |
|
Color blindness and color perception disorders
| Challenges | Solutions |
| Information conveyed only through color is difficult to distinguish. |
|
Hearing impairment
| Challenges | Solutions |
| Audio or video content is inaccessible without assistance. |
|
Motor impairment
| Challenges | Solutions |
| Some people cannot use a mouse or perform precise gestures. |
|
Epilepsy and neurological disorders
| Challenges | Solutions |
| Rapid or flashing animations can trigger seizures or hinder reading. |

Making a website or application accessible is not only a socially responsible action, it is also a major economic advantage.
For many people with disabilities, online services can be more accessible than physical stores. By improving accessibility, you expand your potential customer base, enhance marketing performance, and strengthen your brand image.
The international WCAG (Web Content Accessibility Guidelines) standards define the fundamental rules for making digital content accessible.
Currently, the latest version is WCAG 2.2, but many local regulations still require WCAG 2.1.
Quality assurance testing must integrate these criteria, as any shortcomings can lead to costly redesigns if detected too late.
One of the most common issues is the late integration of accessibility. The later accessibility is considered, the more expensive it becomes.
By incorporating accessibility from the start (user experience, user interface, development, quality assurance), defects are prevented early, costs are reduced, and end users benefit from a product designed for them from the outset.
Disability affects everyone at some point in life—temporarily, gradually, or permanently. Designing with accessibility in mind means designing for every user.
