✿1 Design & Research 2

Step 0 – 1st March 2026

The next two weeks will be focused on developing three different prototypes. My main goal is to explore how interfaces can be designed to better support older adults, especially those who didn’t grow up with digital technology. But before diving into design, I need to ask myself some questions: what is the real problem here? What do older users struggle with the most? Is it that apps and websites are simply too complex, with too many steps and features? Or is it that digital interfaces don’t match the way they expect things to work? Or perhaps it’s not the design at all, but a broader question of digital literacy, understanding how devices, apps and online systems actually function.

Step 1 – 8th March 2026

At the beginning I thought the main challenge would be designing intuitive, accessible interfaces. But as I began talking to people, I realized the picture is much bigger. Many of the people I asked weren’t just struggling with specific apps, they were struggling with digital literacy itself.

This opened my eyes to an important distinction: while good design can make apps easier to use, it can’t replace the need to teach fundamental digital skills. Tasks like navigating menus, understanding security warnings, or even recognizing phishing emails require guidance and practice.

I focused on brainstorming what the digital learning platform should actually teach and how it should support older adults in learning digital skills. Instead of starting directly with the design, I tried to map out the most important areas of digital literacy that the platform could cover. These include basic device skills such as navigating smartphones or adjusting settings, understanding common apps and websites, learning fundamental digital concepts like cloud storage or files, as well as topics related to online security, communication and everyday digital tasks.

While collecting these topics, it also became clear that the platform should not only provide information but guide users through learning in a structured way. One idea that was to create a “Today’s Lesson” feature. Instead of presenting users with many options at once, the platform could suggest one small learning session per day. This approach could help reduce decision fatigue.

Prototype 1

Prototype 2

Prototype 3 – Final Prototype

With the last prototype I tried to move away from the “dashboard” layout a bit and instead focus on something much clearer. Rather than showing lots of different options right away, the interface tries to guide the user through what to do next.

The “Today’s Lesson” feature became the main focus of the layout. It’s the first full-width card right after the hero section and noticeably larger than everything else on the page. The idea is that the most important action of the day should require zero searching. Many older users don’t scan pages the same way younger users do. Instead, they read from top to bottom.

Another element I tried out is a progress tracker with color-coded topics. Each topic has its own color instead of everything looking the same. The idea behind this is that color can become a kind of memory anchor. Over time users might remember something like “orange was the security lessons” without needing to read every label again.

For the lesson library I created video cards that show the duration and difficulty level right away.

Another thing I want to add is an accessibility toolbar directly in the Navigationbar. Instead of hiding text size or contrast settings somewhere deep in a settings menu, the controls (A / A+ / A++ and a contrast toggle) are always visible. My thought here was: if someone needs larger text, they probably need it immediately, not after navigating through several menus they might already struggle to read.

Interaction in Sounddesign

For this first blog post, I had to step a bit outside my comfort zone because we’ve started collaborating with sound designers on a music interface. That alone is already an interesting project. For the first blog post we had to research on nime.com and I came across a study about agency and creativity in musical interaction for people living with dementia and cognitive decline. I find this topic really interesting, especially since it connects in some ways to what I’m considering exploring in my master’s thesis.

Agency and Creativity in Musical Interaction for those living with Dementia and Cognitive Decline

Dementia is an umbrella term for a range of progressive conditions that affect the brain. These conditions can cause challenges with memory, problem solving, cognitive function and decision making. For people living with dementia, musical interventions have been shown to support important aspects of life, such as the sense of self. Sustained engagement with music can have a positive impact despite these challenges.

In this context, agency refers to the sense of control or ownership an individual feels over their actions and the resulting consequences. It describes the experience of being the initiator of one’s actions rather than just responding to external direction.

For people living with dementia, agency is often considered to be diminished. In research, dementia is frequently approached through a biomedical deficit model that focuses primarily on the skills and memories a person has lost. This perspective can lead to the assumption that because language and memory are impaired, agency must also be lost. However, this connection is often taken for granted rather than critically examined.

As a consequence, people living with dementia are frequently viewed as passive participants in therapeutic activities and are often expected to engage only in relatively basic tasks. In the study referenced, for example, participants were limited to playing simple instruments such as percussion while following the lead of experts. This setup reflects and reinforces the assumption that their role is primarily responsive rather than self-directed.

Biomedical deficit model

The biomedical deficit model is a framework commonly used in dementia research that focuses primarily on the skills lost by individuals and the tasks they are no longer able to achieve. This model prioritizes the identification of cognitive impairments, such as challenges with memory, language and problem-solving.

This paper proposed and tested a procedural music platform called the “SliderBox”, which was specifically created for people living with dementia. The goal of the project was to allow people with dementia to go beyond basic interactions to create sound and provide tools that facilitate unguided musical experiences and enabling them to actively participate music activities.

The Hardware: The SliderBox is an accessible MIDI controller made of wood, with eight analogue sliders and eight push-buttons. It provides multi-modal feedback through LED light strips and buttons to help guide the user.

Conclusion

Some participants were struggling when there were more then two possible actions. This also directly related to the engagement, whereas less people would engage with the prototype, when it had to many possible actions.

The researchers also observed that the SliderBox had a high engagement and lack of negative behaviors, showing the potential for those platforms.

In this experiment concludes that it is absolutely possible to facilitate engaging musical interactions that also foster agency and creativity for those with cognitive decline.

#7 Decision fatigue

Update

Here’s a small update on the last blog post where I mentioned that elderly people don’t really use technology for entertainment. Some family members recently got a new TV and were complaining that Netflix is installed everywhere. I talked to them about it and they told me they don’t really understand why it’s there at all. They said they don’t need it and would rather just watch whatever is on TV something random, without having to think about it.

They also mentioned that on Netflix they often don’t even know what they would search for, which makes the whole experience feel unnecessary. With TV, something is always already playing. It feels like they just want to watch without having to decide first and the topic itself doesn’t matter that much. This is something i found quite interesting and will do some research on.

I beliefe this phenomenon might be explained by the following:

Reduced Processing Capacity and Cognitive Effort

  1. As individuals age, their available processing capacity and attentional resources decline, meaning they can process fewer discrete bits of information in a given time. [1]
    • Self-Initiated Processing: Digital entertainment often requires “self-initiated” processing, such as navigating complex menus or reorganising information in working memory, which shows substantial losses with age. [1]
    • Cognitive Load: If a digital interface is cluttered or complex, it demands high cognitive effort to navigate. When the effort required to make decisions within an app (such as choosing content or managing settings) exceeds the user’s available resources, it leads to frustration and a desire to stop using the technology. [2]

The Relationship Between Ease of Use and Usefulness

  1. For older adults, perceived usefulness is deeply linked to ease of use.
    • Immediate Benefits: Older adults are less likely to perceive a technology as useful if its benefits do not manifest easily and quickly during actual use. [3]
    • The “Visual Gymnastics” Effect: Users who have already spent a long day performing “visual gymnastics” to focus on digital content may find it harder to engage with non-standard or complex designs. If a digital entertainment platform requires unnecessary cognitive effort to understand its navigation, it disrupts the user’s mental model and erodes trust. [4]

Age Patterns in Entertainment Attitudes

  1. There is a pronounced age effect specifically regarding communication and entertainment devices (such as tablets and social networks), where positive attitudes towards them fall significantly as age increases. [3]
    • Significant Decline: Compared to those in their 50s, individuals aged 80+ are 47 to 48 percentage points less likely to value entertainment devices. [4]
    • Experience vs. Effort: This decline is partly attributed to older generations having less acquaintance and experience with these devices. Consequently, every interaction requires more “learning” effort, which can be exhausting, leading to a lower perception of the technology’s overall usefulness. [4]

Usability Barriers as a Deterrent

  1. Design flaws that increase decision-making friction directly impact perceived usefulness:
    • Navigation Issues: Confusing or cluttered navigation leads to hesitation and abandonment. [4]
    • Information Overload: Seniors are often more thorough in searching for information but are more prone to being distracted by irrelevant details and losing focus. [5]
    • Numeric and Spatial Fluence: A decline in numeracy can make it difficult for older adults to interpret data-heavy interfaces (like those found in complex gaming or streaming settings), further complicating their ability to see the technology as a “help” or “value”. [2]

Summary Table: Effort vs. Perceived Usefulness

BarrierImpact on Perceived Usefulness
Complex InterfacesIncreases cognitive load, leading to user errors and frustration.
Delayed RewardsIf benefits aren’t immediate, the user views the tool as cumbersome rather than useful.
Working Memory DeclineMakes active updating and navigation effortful and “costly” to carry out.
Lack of ConsistencyDisrupts mental models, causing hesitation and a loss of confidence.

#3 Testing and Research

Background

This week I had a situation that perfectly illustrated why I chose this topic. I was explaining some functionalities of a new app to my grandfather. He has always been very tech-savvy, he still works on his own website but even he struggles with certain concepts from time to time. He often tells me that everything takes him much longer than it used to and even when I show him a quicker or easier way to do something, he still sticks to the method he already knows. I believe this is partly a matter of habit and partly a reluctance to change something that “still works.”

What surprised me most was watching him interact with the app after my explanation. I assumed that once I had shown him how the app worked, it would be straightforward. But when he tried it on his own, he had to stop and ask for help at many points. It made me realize how much prior knowledge and digital literacy designers unconsciously expect from users, even when the interface seems simple to us.

This small moment showed exactly why designing for older adults matters: even motivated users with experience and interest in technology can struggle when interactions are not intuitive, forgiving or aligned with their mental models.

But here comes the real question: Is the problem rooted in the design of digital products or in the mental models that older adults bring with them? In other words, should we focus on improving the interfaces or on helping older people build the conceptual frameworks they need to understand how technology works in the first place?

Research

Problems older adults face with technology usually come from two sides: the design of the technology and the way older people understand and process information. When these two sides don’t match, it leads to confusion and mistakes. [1][3]

Many digital products simply aren’t designed with older adults in mind. This creates barriers that make technology hard to use.

  • Interfaces that feel cluttered or complicated: When apps have too many features or unclear layouts, older adults struggle to find what they need.[3]
  • Physical design that clashes with age-related changes: Small buttons, close-together touch targets or gestures like pinching and swiping can be difficult due to reduced vision, motor skills or dexterity.[3]
  • Unclear icons: Small, abstract or unfamiliar icons can be hard to recognize. Older adults often expect bigger, more descriptive labels instead of symbolic icons. [3]
  • Inconsistent design: If the interface doesn’t behave in predictable ways, it breaks the user’s expectations. This lowers trust and makes people feel unsure about what will happen next. [5]
