HCI Explained

Gestalt Principles in Modern Interface Design

Why does a button feel clickable? Why do some interfaces feel intuitive almost instantly? And why can cluttered apps feel exhausting to use? The answer often comes back to a set of ideas from early psychology known as Gestalt principles. In this episode of HCI Explained, we explore how principles like proximity, similarity, figure-ground, continuity, and closure quietly shape the way people perceive digital interfaces every day. We break down how designers use these principles in products like Netflix, Gmail, Figma, iOS, and Android to guide attention, organise information, and reduce cognitive load without users even noticing. Along the way, we unpack: • Why the human brain naturally groups things together • How spacing can completely change usability • Why visual hierarchy matters more than decoration • Common interface mistakes that violate Gestalt expectations • How to start recognising these patterns in everyday apps This episode is designed for anyone curious about design, UX, psychology, or how interfaces communicate visually without words.

The Evolution of User Research Methods #HCIExplained

User research did not always look like Zoom calls, heatmaps, and analytics dashboards. In this episode of HCI Explained, we trace how researchers studied people and technology from the 1980s to today. We explore the rise of usability labs, contextual inquiry, ethnographic fieldwork, remote testing during COVID-19, and the growing role of behavioural analytics in product design. Along the way, we unpack why user research methods changed, what was gained, what was lost, and why modern UX teams increasingly combine interviews, observation, experimentation, and large-scale behavioural data. If you have ever wondered: • Why companies moved away from traditional usability labs • How remote research changed the industry • Why analytics alone cannot explain human behaviour • How researchers choose methods today …this episode is for you. Whether you are new to HCI, a UX student, or an industry practitioner, this episode offers a practical and historical introduction to how user research evolved into what it is today.

Designing for Failure: Why Good UX Plans for Things Going Wrong #HCIExplained

Failure is not an edge case. It is part of every user experience. In this episode, we unpack why designing for failure is essential in modern UX. From broken flows and system errors to unexpected user behaviour, the best products are not those that avoid failure, but those that handle it well. We cover: • What “failure” means in UX• Why most systems ignore failure states• How poor failure design breaks trust• Real-world examples (error messages, payments, AI systems)• Practical strategies to design resilient experiences If you design only for success, your product will fail your users. If you design for failure, your product earns their trust.

Designing with Uncertainty #HCIExplained S2.E5

Modern technologies don’t always know, and pretending they do can be risky. From AI predictions and recommendations to navigation and health apps, uncertainty is built into how many systems work. The real design challenge is not removing uncertainty, but helping people understand and work with it. In this episode of HCI Explained, we explore what it means to design with uncertainty in Human–Computer Interaction. We discuss: * Why uncertainty is unavoidable in modern systems * How hiding uncertainty can undermine trust and decision-making * The difference between accuracy and confidence * Design strategies for communicating uncertainty clearly * Graceful failure, fallback options, and user agency * Why uncertainty is a design condition, not a bug 💡 Good design doesn’t promise certainty. It helps people make informed decisions despite uncertainty. 👉 Tune in for a grounded discussion on trust, responsibility, and interaction design in an uncertain world. #HCIExplained #DesigningWithUncertainty #HCI #UXDesign #Trust #AI #InteractionDesign

When Good UX Causes Harm #HCIExplained S2.E4

Good UX is meant to help users — but what happens when it doesn’t? Many design patterns celebrated as “good UX” are optimised for engagement, speed, and convenience. Over time, these same choices can lead to overuse, manipulation, and loss of autonomy. In this episode of HCI Explained, we examine how good UX can still cause harm, even when intentions are positive. We discuss: * Why usability and ethics are not the same * How engagement-driven design can undermine well-being * Persuasive patterns that look helpful but create dependency * Why harm often emerges gradually rather than instantly * The limits of metrics like engagement and retention * Designer's responsibility beyond making things easy 💡 A design can be usable, elegant, and successful — and still be harmful. 👉 Tune in for a critical discussion on ethics, responsibility, and long-term impact in UX design. #HCIExplained #UXEthics #DarkPatterns #PersuasiveDesign #HCI #UXDesign #ResponsibleDesign
