UX Design Principles for Seniors and Older Adults, Part II

Before digging into the UX design principles required to connect digital products with seniors and older adults, let's examine the business case that drives this research.

For all the articles written about the Great Wealth Transfer, the spending power of older generations continues to grow. According to AARP, Americans 50 and up contribute $8.3 trillion in economic activity to the US economy each year, with a GDP that's expected to triple by 2050.

This spending power is driven by several factors, including:

• Longer lifespans. People are living longer and healthier lives than ever before, which gives older generations more time to save, invest and spend.
• Higher incomes. Older generations have higher incomes than younger generations for several reasons, often including higher levels of education and work experience.
• Asset accumulation. Older generations have had more time to accumulate assets like houses, stocks and bonds. In short, elders possess wealth.

Given the numbers behind the business case, given the obvious hole in so many established markets, and given that it's simply the right thing to do, let's consider the creative and knowledge gaps that pervade even the best UX and product design teams. In the first part of this series, I shared my own experience giving my father a pair of Apple AirTags, and we reviewed the most common physiological and cognitive changes that product teams and UX designers must consider as they look to connect with this valuable group.

UX design principles specific to older adults

Designing for older adults requires a nuanced understanding of the challenges they face, both physiologically and psychologically. Might it be time for a new approach to designing and testing for this demographic?

Here are the top 10 usability failure points that are unique to this group:

• Small touch targets. As dexterity decreases with age, small buttons or touch targets become challenging. Provide larger touch targets to accommodate less precise fine motor skills.
• Low contrast and small font sizes. Aging eyes may struggle with low-contrast color schemes and small type. Use high-contrast colors, and consider how the overall design holds up when users adjust font sizes.
• Over-reliance on icons without labels. Icons can be intuitive for younger generations who grew up with certain symbols, but they may be unfamiliar to older users (and other cultures). Always pair icons with text labels. Combined with the first two items on this list, clearly labeled, appropriately sized touch targets should be considered table stakes.
• Complex navigation. Too many options or nested menus can be overwhelming. A clear, linear path with fewer steps works better, and the back and home options should be obvious and easy to reach. As always, think carefully about naming conventions.
• Assuming prior knowledge. Avoid jargon that is common among tech professionals but doesn't translate intuitively to others. Instead of assuming a shared knowledge base, provide clear instructions and onboarding tutorials. People of every generation learn differently, so visual cues, audio instructions and text should all be available in tutorial content.
• Lack of feedback. Older users may not be sure their action registered. Immediate feedback, like a button animation or a sound, reassures older users and anyone on a slower device.
• Fast-paced interactions. Animations and features that move too quickly can be disorienting. Keep motion slow and deliberate, and avoid auto-advancing features like carousels. If there is no alternative, use delays of 5 to 7 seconds.
• Non-standard gestures. Stick to universal gestures like scrolling and swiping. New or non-standard gestures can be counterproductive.
• Missing accessibility features. Make sure your design works with screen readers, voice commands and other accessibility tools. Offer options like magnification or read-aloud.
• Ignoring cognitive load. As we age, working memory may not be as sharp. Avoid presenting too much information at once. Break tasks into manageable steps and provide reminders or save points.

Remember, the key is empathy. Qualitative research, like interviews and usability testing with older participants, provides invaluable insight for design decisions. Balancing usability data with medical statistics about how many people are affected by various conditions each year is a good basis for selecting test participants. It's always worth co-designing with your target audience and iterating on their direct feedback and user data, combined with your own observations.

Psychological challenges common among seniors

From a psychological perspective, older adults often have particular concerns about adopting new technology. Many of the physiological changes above reappear in the list below, both to show how these design considerations link body and mind, and to show the compounding effect, positive or negative, of getting it all right.

Here are some psychological insights and matching design tips for product teams looking to grow with this demographic.

Fear of making mistakes. Many older people sincerely worry that they will "break" the technology or make an irreversible error. Jakob Nielsen's ten usability heuristics cover this under error prevention and recovery. Simple fixes, like a more forgiving interface with easy undo and redo and clear feedback messages, go a long way toward reassuring users that they can revert or change an action.

Cognitive overload. When cognitive faculties decline with age, processing information becomes harder. Reduce clutter, pare available actions down to the essentials, and present information in small chunks. Use progressive disclosure to show information as it's needed. A subset of cognitive overload is a principle I call Patience and Pace. Older users may prefer to take their time to understand and interact, so avoid timed actions and let people learn at their own pace, so they never feel rushed.

Social influence. Older adults often trust and value the opinions of their peers most. Use testimonials, case studies or endorsements from people in their age group. Bonus tip: too many product teams track only the actions people take. Personalized guidance around actions not taken is a badly underused way to increase engagement, especially when the message comes from a peer voice.

Emotional resonance. A common misconception among tech professionals and designers is that human behavior is largely rational. It isn't. Engaging people on an emotional level makes them feel valued and understood. Storytelling, and scenarios that resonate with a person's life experience, are not just the domain of our colleagues in marketing and branding. Make sure marketing materials and instructions reflect both lifestyle and aspirations.

Three emotionally resonant drivers encourage people to learn and adopt:

• Self-efficacy. The belief in one's ability to succeed in a specific situation. Onboarding tutorials and positive feedback for completed tasks build confidence.
• Personal relevance. If technology doesn't seem relevant or beneficial, it's less likely to be adopted. Communicate the value in terms that relate to daily life, and highlight benefits that meet real-world needs.
• Autonomy and control. Feeling in control enhances adoption. Clear exit points, customizable settings, and control over notifications and other interruptions all help older users.

By understanding these psychological factors and building them into both the design and the promotion of technology, product teams can better serve older adults. Continuous feedback and iterative design, informed by actual older users, is invaluable.

Conducting UX testing with seniors and older adults

UX testing with older adults calls for a particular approach and sensitivity to their needs and preferences. Here are some considerations and best practices:

• Recruitment and representation. Make sure participants truly represent the demographic you're targeting. A set of screening questions improves selection. Consider factors like comfort with technology, health conditions and previous experience.
• Environment and setup. Test in a quiet, well-lit space. If possible, test in participants' homes, where you can observe them in a natural setting, which will likely yield the best results. Make sure all type on your test materials and interfaces is large enough to read comfortably.
• Duration and fatigue. Keep sessions short. Older participants may tire more easily, so monitor their energy and offer breaks.
• Instructions and clarity. Be clear and specific. Avoid jargon or unfamiliar terms, and be ready to repeat or rephrase instructions.
• Patience and empathy. Give people time to think and respond, and never rush them. They may have different mental models of technology. Listen actively and avoid making anyone feel judged or inadequate.
• Physical considerations. Be prepared for motor or sensory limitations, such as tremors, reduced vision or hearing loss, and make sure your setup accommodates them.
• Encourage open feedback. Reassure participants that there are no wrong answers and that all feedback, positive or negative, is valuable.
• Observe beyond words. Watch for non-verbal cues. A frown, a hesitation or a sigh can be as revealing as anything said aloud.
• Follow-up support. After the session, give participants a summary of what was covered and a point of contact for further questions or feedback.
• Compensation and appreciation. Compensate participants fairly for their time. A small token of appreciation or a thank-you note also makes a difference.
• Data privacy and ethics. Explain clearly how the data will be used and protect participants' privacy. Obtain informed consent and make sure people understand their rights.
• Iterative testing. Older users bring diverse experiences and perspectives. Run multiple rounds with different participants to get a holistic view.

The goal is a comfortable, respectful environment where older participants feel valued and heard. Their insights are invaluable in making products more accessible and usable for their demographic.

Top apps among users 50 and up

One of the best ways to get to know this audience is to learn the products they already use. According to Business of Apps, the top app categories for this group are news, auto, weather, medical, health and fitness, and navigation.

74% of app users in this demographic regularly use Facebook, making it one of the most popular apps for the group. The most popular app for seniors is Speechify, which converts any text to speech with options for voice, speed and highlighting text as it's read aloud.

Tools are another highly ranked category for seniors. Lumosity offers brain training aimed at memory, attention, flexibility and problem solving. Medisafe manages medications, with reminders for when to take pills and alerts to family and caregivers when a dose is skipped. AARP offers its own app, AARP Now, designed specifically for seniors. It provides news and other content, access to member benefits and discounts, local community events and volunteer opportunities, and tools for managing health, including medication reminders, fitness tracking and symptom tracking.

Beyond studying the needs of this audience, it's worth downloading these apps and studying their functionality, design elements and UX features. Above all, designing experiences for seniors requires empathy, which I'll examine in detail in the third part of this series, along with strategies and resources that help product teams put that empathy into practice.
