Not every disability is visible – and some only become apparent when digital technology comes into play. One area that has gained significant attention in recent years involves cognitive impairments – difficulties in understanding, learning or processing information.
This includes people with learning difficulties, dementia, dyslexia or dyscalculia. But it also affects many who have no official diagnosis yet still struggle to make sense of complex texts, navigate nested menus or complete digital forms without errors.
And they are far from alone.
An underestimated majority
According to studies by Maastricht University and Eurostat, depending on the country, between 20 and 45 per cent of adults in Europe experience difficulties reading, understanding complex texts or operating digital systems. In other words, almost one in two people sooner or later reach the limits of digital comprehensibility.
This is not a marginal issue – it is a central social challenge. Those who cannot understand digital content or manage digital systems are effectively excluded from many everyday activities – whether buying tickets online, using a terminal in a supermarket or filling in a form on a government website.
When technology overwhelms
What is meant to be progress can quickly turn into a barrier. Many digital applications are overloaded with icons, jargon and functions that even tech-savvy users find confusing. Time limits during payment, unclear error messages or constantly changing menu structures all add to the feeling of being left behind.
And if people without disabilities already struggle to find their way in today’s digital world – how much harder must it be for those living with cognitive impairments?
Comprehensibility is no coincidence
Good design does not mean simplifying everything. It means structuring information so that it can be understood. This ranges from clear language and intuitive symbols to logical workflows, optional explanations and acoustic feedback.
There are already a few positive examples:
- Public institutions offering websites in ‘Easy Language’.
- Terminals that automatically switch to a simplified mode when users choose that option.
- UX designs that provide orientation through clear structures and consistent symbolism.
But that is still not enough.
True accessibility does not happen at a desk – it happens in dialogue with the people who need it.
Turning affected people into active participants
If digital systems are to become truly inclusive, they must be developed together with users – not over their heads. This is particularly important for people with cognitive impairments.
They know best where comprehension ends and confusion begins. Their perspective can reshape the design process – leading to user interfaces that are intuitive, enable clear decisions and exclude no one.
UX designers, developers, manufacturers and retailers all share responsibility here:
to design not only for people, but with them.
Conclusion
Accessibility does not mean making technology simpler – it means designing it so that it can be understood.
When 20 to 45 per cent of the population struggle with complex digital content, that is not an exception – it is a clear call to action.
Cognitive barriers are not rare; they are part of everyday life. And they will not disappear through new software, but through new ways of thinking.
Those who turn affected people into active participants do more than create accessible products – they build a digital world that truly works for everyone.
