Finding Delight in Serious Software

These views are understandable – it’s easy to focus on our own work and see the product through a narrow lens – but we’ve seen time and time again that this rigid way of thinking can actively work against the successful adoption and use of a product.

Last month, I wrote about the importance of giving thoughtful interface design a seat at the table in order to achieve greater usability, clarity and confidence in a hardware system. All of which ladder up to a more effective and more adoptable product.

This time, let’s talk about a secret weapon that can supercharge even the most complex of systems: delight.

Suggesting that a machine interface should be delightful to use can lead to raised eyebrows and strange looks. Reverse the framing, though, and it seems far easier to believe that people don’t want to use boring, unappealing, disengaging or sterile products.

Many of the hardware endeavours we support become the tools and systems people use at work day-in, day-out, to make scientific breakthroughs. Crafting both an effective and delightful experience here leads to better usage outcomes, greater trust in the system, a boost to product loyalty, and it can brighten each operator’s day. Good for their work; good for the businesses making the product; and good for the humans at the heart of it all.

Our approach is to lean into the pursuit of delight rather than subtly shuffle around it. Throughout the process – just as we review designs to ensure we’re enabling execution of key functions and matching up to the mental models of operators – we are consistently asking how we can bring more joy and elevate the experience to the next level.

Sometimes, it’s a ‘big picture’ view of delight that we take into a project.

We recently completed a project to re-design the digital interface for a suite of battery and chemical calorimeters – high-risk equipment that deals in big temperatures, large pressures, and potentially catastrophic consequences if not controlled properly.

This ethos pushed us beyond a replication of existing functionality with a fresh lick of paint (well, pixels) towards an interface and experience that will genuinely differentiate the product from its competitors and build renewed trust with its operators.

We’re looking forward to sharing more on this particular project once it’s launched in the coming months.

In other cases, it’s more about looking at how an interface behaves in the smaller moments. We look for ways to make every interaction feel intentional and, where appropriate, delightful. A button that acknowledges input with a gentle flourish. An animated transition between states that guides attention without demanding it. Illustrations accompanying feedback that confirms a system is under control.

These moments might seem small, but they’re where the trust is built. For the operators we design for, these delightful micro-moments aren’t embellishments; they’re signals that the system is listening, stable and dependable. When we handle these details with care, the interface starts to feel like a supportive ally rather than just a tool, and trust and loyalty will continue to grow.

Our focus on these micro-moments with iFast and MFX has led to the development of hardware systems that people want to use, rather than feel forced to. With over £10m of funding under their belts since our journeys together began, our interfaces continue to ensure the science beneath can make a real impact.

Delight isn’t an optional extra or something that sits on top of function. It’s a core part of how people experience, trust, and adopt complex systems. Whether we’re designing for scientists, engineers, or operators, the same principle applies: if a product feels great to use, it works better for all.

Our advice to teams building technical tools and scientific hardware is to treat moments of delight as a measure of quality, not a distraction from it. It’s the bridge between human intuition and system precision; a sign that design and engineering are working in harmony.

Here are three ways to weave delight into the design and development process from the very start:

1. Zoom out to the big picture
   Start by defining the overall experience you want users to have. Is it anchored to confidence and calm? Perhaps it’s more about mastery and precision? Or maybe it’s about making people feel like super-smart spaceship pilots? Use this overarching aim to guide decisions about structure, hierarchy and interaction styles. When the intent is clear, even the more complex of tools can feel great.

2. Obsess over the small moments
   Micro-interactions, motion, and feedback shape how a system feels in use. These details signal reliability and care, deepening trust and encouraging repeat use. This doesn’t have to eat into time or project spend, pick the crucial moments and make them count.

3. Champion delight as a shared goal
   Bringing joy to serious software isn’t just the job of designers. Engineers, product owners and scientists all contribute to how a system behaves and communicates. When everyone shares ownership of the user’s experience, delight becomes a natural outcome, not an afterthought.

Delight doesn’t mean flashy or frivolous. It’s about creating tools that people want to use. Interfaces that feel considered and capable. Because when complex machines are a pleasure to use, their potential to make an impact grows ever bigger.
