NHM NFC-Enabled Interactive Exhibits
A hardware-and-digital kiosk built to stop visitors abandoning crowded exhibits, driving engagement gains.
Visitors Said They Wanted More Information. Then Walked Away From the Kiosks That Provided It
That contradiction was the whole problem — observed directly on the floor, not inferred from a survey. The design had to serve what people actually did, not what they said they would do.
This was a collaborative academic project with three peers. Initial research — user interviews, surveys, and naturalistic observations on the NHM floor — was shared equally across the team, producing collective mid-fidelity designs at submission. What I continued independently: a solo round of high-fidelity usability testing and the final prototype built from those iterations.
The answer wasn't more information — it was less, faster. Visitors read a short exhibit fact, tap their NFC wristband, and answer a quick quiz question, all within 90 seconds. Get it right and the wristband logs a reward stamp to collect across the museum. The kiosk resets after 15 seconds so nobody's waiting.
92% Engage With Touchscreens — But Fewer Than Half Use Museum Apps or Scan QR Codes
Distributed to a general museum-going population, not NHM visitors specifically. Results are directionally valid but not NHM-specific.
Visitors engage with hands-on exhibits — 90% use touchscreens. But fewer than half use museum-provided apps (46%) or scan QR codes (45%), with 66% navigating spontaneously. A dedicated physical token over a downloadable app was the obvious call.
A Reconnaissance Day Across Three London Museums Established the Kiosk Conventions Worth Following
We spent a day across the Natural History Museum, the V&A, and the Design Museum, photographing kiosk installations and talking to visitors. The most-used kiosks shared a clear pattern: high-contrast buttons, with the primary interaction anchored in the middle zone to minimise reach distance — which fed directly into Decision #1.
11 Interviews and On-Floor Observations: Visitors Claimed They'd Read More, Then Walked Away From Text-Heavy Kiosks Within Seconds
Visitors claimed to want more information but consistently abandoned text-heavy kiosks within seconds. Passive reading had no incentive — visitors needed an active reason to engage.
Problem #1
Queues Caused Abandonment Before Any Interaction
During peak hours, visitors gave up and left exhibits after waiting in queues — before they'd touched anything at all.
Problem #2
Reading Without a Goal Led to Drop-off
Information-dense kiosks with no clear task were ignored. Visitors needed an active reason to engage with text, not just a passive invitation to read.
Problem #3
Interactions Without Feedback Felt Pointless
Without a visible outcome, visitors didn't feel the effort was worth it. Something tangible at the end changed that.
Problem #4
Screens Competed With the Physical Exhibit
The UI had to supplement the artefact without becoming the main visual attraction — a constraint that shaped the entire visual direction.
"How might we replace the passive act of reading about an exhibit with an active reason to stay — without turning the screen into the main attraction?"
Mid-Fidelity Testing With Five Participants Found Three Structural Flaws Before Hi-Fi Began
We tested the mid-fidelity wireframes with five participants to validate the core mechanics. Three problems needed fixing before visual design started.
First, the 20-second timer caused panic. The original time-box was too aggressive, producing rushed errors.
Second, a digital 'Finish' button broke the mental model. Users were confused by a digital button at the end of the flow — it contradicted the physical tap-in/tap-out transit model they already understood. Removed entirely in hi-fi, making the wristband tap the final action.
Third, hardware and software got confused. Mid-fi screens included an NFC scan icon. Users tapped the screen glass instead of the physical reader, wasting their interaction window.
Design Decisions
Decision #1
A Three-Row Grid Maps High-Frequency Interactions to the Chest-Height Reach Zone
On-floor observation showed visitors struggling when buttons were placed at screen extremities. We designed a three-row horizontal grid with three distinct zones: a no-go zone at the top, a Primary Interaction Band at chest height for all high-frequency Yes/No actions, and a navigation zone at the bottom.
Decision #2
Signalling a Quiz Gives Visitors a Reason to Actually Read
The interface gamifies the reading experience. The home screen breaks content into scannable chunks that prime visitors for an upcoming timed quiz — because the challenge is signalled from the first tap, passive reading becomes active preparation. Maximum read time in testing was 25 seconds. Combined with the 30-second quiz window and a short buffer, the full session stays within the 90-second cap.
Decision #3
An NFC Wristband Sidesteps Phone Fatigue — Tap In, Tap Out, Done
Survey data showed visitors avoid scanning QR or NFC tags with their phones. Rather than forcing a download or requiring a personal device, we issued a dedicated physical token instead.
My teammate Dominique originated the concept and developed the core interaction model. We refined it together, anchoring it to the tap-in/tap-out motion used on London transport gates. No unlocking required. One tap starts the session; one tap collects the reward.
Decision #4
Two-Tier Rewards: Participation Stamps for Trying, Prestige Badges for Getting It Right
A two-tiered stamp system gives everyone something for taking part, while reserving a prestige badge for the correct answer — giving visitors a reason to actually try rather than guess.
Decision #5
A 90-Second Session Cap and Idle Reset Keep the Queue Moving
Observation showed queues forming behind popular screens, making users anxious and pushing them to rush or abandon. Two session rules address this.
First, the quiz is a single rapid-fire question. Combined with a 30-second time-box and the 25-second maximum reading time, the full interaction stays under 90 seconds. Second, an idle reset handles visitors who walk away without tapping out — a 15-second inactivity countdown hard-resets the kiosk for the next person.
Hi-Fi Testing Found 45 Seconds Was Too Long — 30 Seconds Was the Sweet Spot
To fix the 20-second panic from mid-fi, I ran a solo round of usability testing on the hi-fi prototype — initially bumping the timer to 45 seconds based on the mid-fi data.
Users didn't finish quickly. They filled the full 45 seconds, lingering at the screen. A second iteration dropped it to 30 seconds. That gave enough time to answer without feeling rushed, and enough pressure to stop dawdling.
Reflections
My First Time in a Design Team
Working in a team for the first time was stranger than I expected. For the first few weeks I kept my opinions to myself, not sure whether what I was thinking was worth raising next to people who'd spent more time at this. That changed gradually — mostly because the work didn't leave much room for staying quiet. By the final stretch I was pushing back on decisions I'd have nodded along to in week one. Most of that came from teammates who also acted as mentors and made it safe to get things wrong.
Academic Freedom Hid Real-World Constraints
Without real business pressures, NFC wristbands were easy to propose. Actually shipping them is a different problem. Sanitation, distribution, hardware upkeep — the concept probably doesn't survive an ops conversation. The accessibility gaps are just as bad. A 25-second reading timer cuts out users with dyslexia. A fixed chest-height zone doesn't work for wheelchair users. Those aren't details to patch later. If this were a project to be deployed for real, I'd be raising the public-space accessibility question from day one.
