Why Good Design Feels Good: What Jakob Nielsen Taught Us About Usability

Have you ever clicked the “Download” button... and then waited in silence, wondering if anything was actually happening? No spinning wheel, no progress bar, just... hope?

That’s not just annoying — that’s bad interface usability. And if you've ever felt that frustration, you’ve walked straight into one of Jakob Nielsen’s usability traps.

Let’s talk about it.

Meet Jakob Nielsen: The Sherlock Holmes of User Interfaces


Before smartphones, Canva, or TikTok, there was Jakob Nielsen — a Danish usability guru who asked a radical question in the early ’90s:

“Why are digital tools so frustrating to use… and how can we fix them?”

He wasn’t just guessing. Nielsen built a career on testing, observing, and explaining why some websites and apps make us feel smart — and others make us feel like we’ve lost 20 IQ points.

In 1995, he introduced the famous:
👉10 Usability Heuristics for User Interface Design — a list of common-sense rules that still shape how we design everything from mobile apps to smart elevator panels.

 What Is Usability, Anyway?

Usability isn’t about making something look pretty — it’s about making it work. It means:

  • You know what to do

  • You know what’s happening

  • You don’t need a manual

  • You feel in control

  • You don’t scream at your screen

In Nielsen’s world, a good interface should be like a good butler: always there when you need it, never in the way.

 The Heuristics That Still Run the World

Here are a few of Nielsen’s golden rules — in plain English — and why they matter:

1. Visibility of System Status

The system should keep you in the loop.

Why it matters: Ever clicked “Submit” and nothing happens? That’s a visibility fail. A progress bar or spinner can turn panic into peace.

2. Recognition Rather Than Recall

Don’t make people remember things. Show them.

Why it matters: If your buttons only use icons and no labels, users might forget what they do — especially if they’re new. Hint: This happens a lot in Zoom and Canva.

3. User Control and Freedom

Give users a way out.

Why it matters: Accidental clicks happen. Let users undo, go back, or cancel. Otherwise, they’ll feel trapped — and possibly rage-quit.

4. Consistency and Standards

Use familiar patterns. Don’t reinvent the wheel unless it’s broken.

Why it matters: If the “trash” icon doesn’t delete, we’ve got problems. Consistency saves brainpower.

 Real-Life Examples (a.k.a. Interface Fails)


Twitter (Old Version)

In older versions (prior to 2020), Twitter would sometimes reject weak passwords like 12345 or password, and simply display:

❌ “Your password is too weak.”

…but it didn’t tell the user what to do next — no suggestions, no criteria, no real-time guidance.

This left many users (especially less tech-savvy ones) confused:

  • Was it about the length?

  • Should I include numbers? Symbols?

  • Is a passphrase allowed?

Because the system didn’t provide error recovery guidance, it violated Nielsen’s Heuristic #9 (Help users recognize, diagnose, and recover from errors) and Heuristic #10 (Help and documentation).

 Later Fix:

Twitter (and many other platforms like Instagram, Zoom, and Gmail) later added real-time password checklists, like:

  • ✅ Must be at least 8 characters

  • ✅ Include at least 1 number

  • ✅ Include 1 symbol

  • ✅ Avoid common passwords

This change significantly improved user experience and aligned with usability best practices.


Why These Small Things Matter

You might think these are just minor inconveniences — but research says otherwise.

Studies show that unclear feedback or lack of user control can lead to frustration, repeated actions, and even tool abandonment (Fornauf & Erickson, 2020). In education and design, where tools like Canva are increasingly used, improving usability isn’t just a luxury — it’s essential to efficiency, trust, and learning outcomes (Glazier & Harris, 2025; Mayer, 2024).

Summary

Design is more than decoration. It’s communication, direction, and empathy. As Nielsen’s heuristics remind us, a usable interface isn’t just one that works — it’s one that makes the user feel smart, supported, and in control.

So the next time you click a button and wonder if anything’s happening, remember: that moment of doubt is exactly what Nielsen taught us to avoid.

Let’s design systems that talk back — not leave us guessing.

Press Play: Reflecting on Game Elements and Gamification in Learning

                                                                                  When we hear the word game , we often think of fun, competition, or leisure. However, preparing and presenting Game Elements & Gamification in our Game-Based Learning course challenged me to see games not just as entertainment, but as carefully designed systems for motivation, engagement, and learning . This reflection explores what I learned from the presentation, how theory and practice intersect, and why play deserves a serious place in education. Games Are Built on Purpose, Not Chaos      One of the strongest insights from the presentation was that every game begins with a clear objective . Whether it is checkmating an opponent in chess or...

Sound in Multimedia: More Than Just Noise—It’s Memory, Mood, and Meaning

Close your eyes and think of a school bell. Or the “ding” when you get a correct answer in a game. Without seeing anything, your brain already reacts. That’s the power of sound —a tool that goes beyond decoration. In multimedia learning, audio is more than background—it’s a cognitive guide, an emotional hook, and an invisible teacher . Let’s dive into how sound works in learning, what the science says, and how smart audio design makes content not only memorable—but meaningful. Why Sound Matters in Learning While visuals often take center stage in educational media, sound plays a quiet but crucial role . It guides attention, sets emotional tone, and helps learners stay engaged. According to Mayer’s Cognitive Theory of Multimedia Learning , we process information through two channels: visual and auditory . If too much is crammed into one channel, learners get overwhelmed. But when sound is used strategically, it balances cognitive load (Mayer, 2020). Think of narration that expl...

Learning on the Table: Designing and Playing an Educational Board Game

Gambar
          Board games have a unique power in education. They bring learners together around a shared space, encourage communication, and turn learning into a social experience. Unlike digital games, board games rely on face-to-face interaction, physical components, and collective decision-making, all of which support meaningful learning and collaboration (Salen & Zimmerman, 2004).      Inspired by this idea, one of our assignments was to design an educational board game , test it with real players, and reflect on both the design process and learning outcomes. Why Board Games Matter in Education      Research shows that board games support learning by combining rules, goals, feedback, and social interaction into a single experience. Physical board games encourage turn-taking, discussion, negotiation, and shared problem-solving, which aligns strongly with social constructivist learning theory (Vygotsky, 1978).    ...
