Booking a medical appointment, checking a bank account, receiving a document from the local council, making a video call with the grandchildren: more and more essential services go through an app or a website. For many older people this is an opportunity, but also a source of anxiety, because interfaces are often designed by and for young people with good eyesight, steady hands and long experience of digital conventions.
Designing with age in mind does not mean creating «simplified» or childish versions. It means recognising common physical and cognitive changes and removing the barriers that make use difficult.
What changes with age
Everyone is different, and many older people use technology with great ease. There are, however, frequent changes worth considering.
Sight
With age, the ability to focus close up declines, sensitivity to contrast drops, sensitivity to glare increases and the perception of some colours changes, especially low-saturation blues and greens. Small light-grey text on a white background, very fashionable, is one of the first barriers.
Hearing
Age-related hearing loss often affects high-pitched sounds. Faint audio alerts, videos without captions and phone-only support can exclude people.
Dexterity
Tremors, arthritis in the hands and reduced precision make small targets difficult, as well as complex gestures such as dragging or pinching, double clicks and actions that require a long press.
Memory and attention
Remembering passwords, codes received by text message, the route taken to reach a page or the meaning of an icon seen once can take more effort. Interruptions, such as notifications and windows opening on their own, also weigh more heavily.
Experience and trust
People who learned to use technology as adults may not know conventions that designers take for granted: the three-line menu, scrolling to see more options, the difference between a notification and a message. Added to this is the fear of making mistakes, of «breaking» something or of falling for a scam.
Concrete measures
| Area | What to do |
|---|---|
| Text | Generous size, good contrast, the ability to enlarge without breaking the layout |
| Buttons | Large, well spaced, with a text label and not just an icon |
| Navigation | A simple, consistent structure, current location always visible, a reliable «Back» button |
| Gestures | Every action done with a gesture must also have an equivalent button |
| Timing | No sessions that expire too quickly, the option to extend time |
| Forms | Few fields per page, format examples, clearly explained errors |
| Confirmation | A summary before important actions and a clear confirmation afterwards |
| Help | A human contact that is easy to find, through several channels: phone, email, chat |
Labels before icons
An icon on its own is a small puzzle to solve. The envelope, the cog, the heart and the bell are familiar to people who use apps every day, much less so to those who use them rarely. Adding a word to the main icons, such as «Messages» or «Settings», is one of the simplest and most effective ways to improve usability, and not only for older people.
Reducing the fear of making mistakes
Many older users hesitate because they fear irreversible consequences. A few choices help build confidence:
- being able to undo an action just taken;
- asking for confirmation before deleting, paying or sending;
- explaining clearly what will happen when a button is pressed;
- not asking for sensitive data without saying why;
- presenting official channels in a recognisable and consistent way, so that it is easier to tell a genuine message from a scam attempt.
On this last point, organisations can do a lot with simple, clearly communicated rules, such as «We will never ask you for your text message code over the phone». A rule that is repeated and respected helps people recognise fraud attempts.
System accessibility settings
Smartphones and computers offer many useful features: larger text, bold text, zoom, increased contrast, reduced motion, read-aloud. A well-designed app respects these settings rather than ignoring them. If users have chosen larger text on their phone, the app must adapt without cutting off words or overlapping elements.
How to test
Involving older people in testing is the most reliable way to discover real problems. Some practical advice:
- Recruit people with different levels of familiarity with technology, not just the most experienced.
- Let them use their own device, with their own settings, where possible.
- Explain clearly that you are testing the product, not the person: mistakes are useful information.
- Allow more time and a calm pace.
- Pay particular attention to hesitation: a moment of uncertainty in front of a button often points to an unclear label or position.
In my work I have noticed that the solutions that come out of these tests, such as clearer labels, bigger buttons and shorter journeys, almost always end up improving the product for every age group.
In short
- Older people are a large and varied audience, not a group to be given childish interfaces.
- Sight, hearing, dexterity and memory change with age: adequate contrast, sizes and timing make a difference.
- Icons accompanied by text and alternatives to gestures remove many barriers.
- Undo, clear confirmations and recognisable official channels reduce the fear of mistakes and the risk of scams.
- Testing with real older users reveals problems whose solutions improve the product for everyone.
