Every day, you’re already engaging in multimodal interaction, whether you’re tapping on a screen, speaking to a virtual assistant, or combining gestures and voice commands in your car. But what does it really mean when technology supports more than one way of communicating? And how does it change the way we design, use, and experience our digital tools?
In this episode of HCI Explained, we explore multimodal interaction: the blending of touch, voice, gesture, and other input modes to create more natural, flexible, and powerful ways of working with technology.
🔹 What we cover in this episode:
The basics of multimodal interaction and why it’s a step beyond single-mode systems.
How combining modalities (like voice + touch, or gesture + gaze) reduces cognitive load and enhances accessibility.
The challenges designers face when blending modalities, including context, consistency, and system complexity.
Everyday examples: voice assistants, adaptive car interfaces, VR/AR environments, and smart devices.
Emerging frontiers: AI-driven multimodality, where systems learn and adapt to your preferred ways of interacting.
Multimodal systems aren’t just about convenience, they represent a major shift in human-computer interaction (HCI). They allow more inclusive experiences, support diverse user needs, and create interfaces that adapt to us rather than forcing us to adapt to them.
As automation and AI increasingly shape how we live and work, multimodal interaction also raises fascinating design and ethical questions:
How can we ensure systems remain intuitive while growing in complexity?
What happens to agency when the system “decides” which mode to prioritise?
Can multimodal interaction help close accessibility gaps, or will it widen them if not carefully designed?
By the end of this episode, you’ll have a clearer sense of how multimodal interaction is already shaping your daily tech experiences and how it could transform the future of human-AI collaboration.
🎧 Tune in and let’s unpack the many voices, touches, and gestures that are redefining interaction.

What if your body wasn’t just a tool to operate technology but the interface itself? From swiping on a touchscreen to moving through a VR world, your body is already shaping how you experience the digital. This is the essence of embodied interaction, an HCI perspective that sees the body not just as an input device, but as central to how we think, act, and connect with technology.
In this episode of HCI Explained, we dive into the fascinating world of embodied interaction, exploring how movement, posture, and gestures allow us to interact more naturally with digital systems.
🔎 What you’ll learn in this episode:
The roots of embodied interaction: How human cognition is shaped by our bodies, and why this matters for technology design.
Everyday examples: Touchscreens that respond to swipes, fitness trackers that map movement, VR headsets that sense orientation, and gesture-based controls in gaming.
Beyond the basics: How embodied interaction is pushing into advanced areas like full-body tracking, somatic design (using the felt experience of the body in design), and augmented movement through wearables or robotics.
Theoretical underpinnings: Links between embodiment, perception, and cognition that make these interactions feel natural rather than artificial.
Social and cultural contexts: Why the meaning of a gesture or movement can shift depending on who uses it and where.
Future directions: From brain-computer interfaces to somatic play, embodied interaction could transform not just usability but also creativity, therapy, and social connection.
💡 Why this matters
Embodied interaction challenges us to rethink the boundaries between body and computer. It makes interactions more intuitive, immersive, and human-centered, while also raising important questions: How do we design responsibly when tech literally moves our bodies? How do we ensure inclusivity when bodies differ in ability, culture, and context?
By the end of this episode, you’ll see that your body isn’t just using technology, it’s part of the interface itself.
🎧 HCI Explained brings you weekly insights into the hidden principles shaping how humans and computers connect.
Every time you open an app, scroll through a website, or manage a cluster of browser tabs, your brain is doing more than you realise. It’s not just clicking and scrolling — it’s building a mental map of a hidden digital landscape. These internal representations, called cognitive maps, shape how we navigate, find information, and make sense of complex digital worlds.
In this episode of HCI Explained, we explore the fascinating role of cognitive maps in Human-Computer Interaction (HCI). Originally studied in psychology to explain how humans and animals navigate physical spaces, cognitive maps now help us understand how people orient themselves in vast digital environments.
🔎 What you’ll learn in this episode:
How cognitive maps, once tied to navigating cities and physical spaces, now extend to digital platforms.
Everyday examples: feeling lost in a sea of tabs, learning the layout of a new app, or remembering where settings are in your phone’s OS.
How users build these maps through repetition, patterns, cultural conventions, and landmarks like icons, menus, and breadcrumbs.
The difference between good design (that supports mental mapping with clarity and consistency) versus poor design (that leads to confusion, frustration, and abandonment).
How disorientation in digital spaces mirrors being lost in real ones — and why that costs time, energy, and trust.
Design strategies to support user maps: clear landmarks, predictable layouts, and consistency across contexts.
Future frontiers: how AR and VR extend physical navigation into virtual environments, how AI may serve as adaptive “guides,” and the ethical questions of whether designers should empower exploration or funnel behaviour.
💡 Why this matters
Cognitive maps explain why some interfaces feel intuitive while others leave us struggling. They reveal how design choices directly affect user orientation, memory, and satisfaction. Understanding cognitive maps can revolutionise the way we design digital spaces — making them more navigable, humane, and empowering.
By the end of this episode, you’ll see that you’re not just “using” apps and websites — you’re exploring invisible landscapes your brain is constantly mapping.
🎧 HCI Explained is your guide to uncovering the hidden principles that shape our interactions with technology.
Every tap, click, and swipe leaves a trace — and the system whispers back. That whisper is feedback.
In this episode of HCI Explained, we dive deep into the fascinating world of feedback loops in Human-Computer Interaction, uncovering how they keep us informed, reduce errors, and help us build trust in the technology we use every day.
Think about the everyday moments when feedback quietly reassures us:
The satisfying click of a keyboard key that tells you a letter has been typed.
The illuminated elevator button confirming your request has been received.
A progress bar creeping forward, reassuring you that your upload is on its way.
Without these signals, technology feels broken, uncertain, or even untrustworthy. Feedback is not just a convenience — it’s a core requirement of good design.
🔎 In this episode, we explore:
Everyday feedback in action: simple but powerful examples that show why feedback is indispensable in both physical and digital worlds.
The forms of feedback: visual (icons, progress bars, status lights), auditory (beeps, alerts, notification sounds), and haptic (vibrations, tactile clicks), and how they can be combined to enrich user experience.
Positive and negative feedback loops: how games keep us hooked, how wearables like smartwatches encourage healthier habits, and how AI-powered recommendations adapt over time.
Good vs. bad feedback: why vague error messages frustrate users, while clear, timely, and actionable feedback empowers them to recover quickly.
Best practices for feedback design: covering timeliness (instant vs. delayed responses), clarity (avoiding confusion), proportionality (feedback that matches the action), and accessibility (feedback that works for all users, regardless of ability).
Emerging frontiers: how feedback loops evolve in immersive environments like AR and VR, how IoT devices use feedback to blend into our everyday routines, and how conversational agents are changing the way feedback is delivered through natural language.
Along the way, we ask important questions:
What happens when feedback is absent or misleading?
How does feedback shape our sense of control, trust, and engagement with technology?
In a future where AI anticipates our actions, how much feedback will we really need?
✨ By the end of this episode, you’ll see feedback not as an afterthought, but as the heartbeat of interaction design — the invisible thread that connects user intention with system response.
🎧 Join us as we decode how feedback loops shape not just our digital world, but also our minds, behaviours, and expectations of technology.

Why balancing affordances and constraints is crucial for good UX
In today's fast-paced technological landscape, "User-Centered Design" (UCD) is a term often thrown around, but its true depth and transformative power are frequently misunderstood. Too many assume it's simply about conducting a single usability test or a quick user interview. But as this episode will reveal, UCD is a far more comprehensive, dynamic, and profoundly evolving practice that reshapes how we build products and experiences.
Join us as we embark on a journey to uncover what UCD truly means, moving beyond superficial understandings to explore its fundamental principles and pervasive influence. We'll delve into the iterative nature of UCD, a continuous cycle of empathy, ideation, prototyping, and testing, demonstrating how this ongoing engagement with users empowers them not just to react to designs but to actively co-create solutions. This isn't just about understanding user pain points; it's about deeply immersing ourselves in their worlds, anticipating their needs, and responding with agility.
We'll challenge the notion that empathy alone is sufficient. True UCD demands more: it must be ethical, ensuring privacy, avoiding manipulative "dark patterns," and designing for fairness and transparency. It must be inclusive, proactively addressing the diverse needs and abilities of all potential users, breaking down barriers rather than creating them. And crucially, it must be adaptive, capable of evolving alongside new technologies and shifting user behaviours.
Prepare to expand your understanding of where UCD is applied today. We'll explore its critical role in shaping modern interfaces, from the intuitive interactions of AI systems and the seamless integration of wearables to the immersive and often complex experiences of virtual and augmented reality environments. How do you truly centre a user when the "interface" might be a voice assistant, haptic feedback, or an entire digital world? This episode tackles these cutting-edge challenges, revealing how UCD principles are being reimagined for the future.
This episode is for anyone who has ever grappled with the question of how to design better for people. It's not just about designing with them in mind, but fundamentally with them involved at every stage. We'll prompt critical reflection on what it genuinely means to "centre the user" in an era of unprecedented technological advancement and increasing societal complexity. Discover how a robust, ethical, and adaptive UCD approach can lead to products and services that are not only functional and usable but also truly meaningful, delightful, and impactful for everyone.
