McDonald’s: Save the Sundae Cone

A melting cone that asks the street to help

Summer is here and McDonald’s is back with an interactive outdoor campaign built around one simple problem. A giant LED billboard in Bukit Bintang, one of Kuala Lumpur’s best-known shopping districts, showcases the iconic Sundae Cone. But it is melting.

To save it, people use their smartphones to spin a fan on the billboard, bring the temperature down, and stop the cone from disappearing.

The mechanic: one shared control, one visible outcome

The execution translates an abstract idea, “cool it down,” into a single piece of viewer control. You open the experience on your phone and spin a fan. The billboard responds in real time. When more people join in, the cooling effect accelerates, so the experience naturally becomes collaborative rather than solo.

In some write-ups, participation is also rewarded with a Sundae Cone e-voucher that arrives on the phone, adding a clean payoff to the play.

In high-footfall retail districts, interactive DOOH, meaning public digital screens that react to what people do, works best when the action is obvious, social, and instantly rewarded.

In high-density urban retail districts, the win is not interactivity by itself but a public action that converts attention into nearby store traffic.

Why it lands

It is instantly legible from a distance. Something is melting. A crowd can fix it. Because the phone gesture maps directly to the visual problem on the screen, people understand the task instantly and the crowd can follow the result without explanation. That clarity creates a low-friction loop: notice. join. watch the shared progress. earn the reward. The “melting” constraint also adds urgency without needing any heavy messaging, and the big screen makes every participant feel like they are influencing something larger than a banner.

Extractable takeaway: If you want people to interact in public, reduce the mechanic to one familiar gesture, make the result visible to everyone, and design the reward so participation feels worth it even for a 30-second engagement.

What McDonald’s is really buying

The real question is whether the screen can turn public play into store-proximate action before attention drifts. This is a strong retail DOOH execution because the interaction, the product promise, and the path to redemption all reinforce each other. This is not only awareness. It is behavior. Get people to take out their phone, do a playful action tied to heat and refreshment, and then convert that attention into a reason to walk into a nearby store. The billboard becomes a live demo of “cool relief,” not a static claim.

What retail teams should borrow

Design for crowds first. If spectators cannot immediately understand what participants are doing, participation stalls.
Make progress collective. Shared outcomes create social proof and naturally recruit more people.
Keep the gesture native. One simple interaction beats a clever multi-step flow in outdoor environments.
Tie reward to proximity. If you can convert engagement into a nearby redemption moment, the media becomes a traffic engine.

A few fast answers before you act

What is “Save the Sundae Cone”?

It is an interactive digital out-of-home campaign in Kuala Lumpur where a billboard shows a melting Sundae Cone and invites the public to cool it down using their smartphones.

How do people control the billboard?

They use their phone to spin a fan mechanic that cools the on-screen temperature. More participants increase the effect, making it collaborative.

Why is the melting mechanic effective?

Melting creates urgency that anyone understands, and it turns participation into a visible “save” moment the crowd can watch.

What makes this a strong example of interactive DOOH?

The action is obvious, the feedback is immediate, and the experience becomes social because progress is shared on a large public screen.

What is the key takeaway for other brands?

Use one native gesture, show real-time feedback in public, and reward participation quickly so interaction feels like a fair trade.

Playable Music Posters: Tap to Hear

Borders between media are blurring. Books are being swiped, magazines digitally scrolled and even in print one can today occasionally navigate. So it is no surprise when regular paper posters come to life on being combined with bluetooth, conductive ink, sensors and speakers.

Paper as an interface, not a surface

The mechanism is straightforward. Conductive ink turns parts of a poster into touch-sensitive zones. Sensors detect taps, knocks, or touch patterns. Bluetooth and small speakers, or a paired phone, provide the audio output. The poster stops being an image and starts behaving like a controller.

In public retail and event environments, touch-based posters only work when people feel safe and permitted to interact.

In consumer marketing and live environments, interactive print means print that senses touch and triggers a digital response. It is a way to turn passive out-of-home into a touchpoint that behaves like a device.

Beck’s Playable Poster

Looking for an innovative way to mark New Zealand’s Music Month, Beck’s partnered with Shine to design a playable poster. Using conductive ink and speakers the posters were made playable with a simple tap of the finger.

The Sound of Taste

Herb and spice brand Schwartz is all about flavour. So to dramatise flavour which was invisible and silent, they got print tech collective Novalia and ad agency Grey London to collaborate on an interactive poster. The poster used conductive ink to turn the surface area of the paper into an interactive interface that also connected to the viewers smartphone to deliver a richer experience.

Change the tune

Agency Republic from UK created a poster with an embedded sensor which when knocked changed the song being played on the agencies shared sound system.

Why these work: the demo happens in your hands

Each example keeps the interaction legible. Tap to trigger sound. Touch to explore flavour as audio. Knock to skip a track. The poster does not ask people to learn a new behavior. It hijacks an existing one, touching a surface, and rewards it instantly.

Extractable takeaway: When you want print to feel alive, make one obvious gesture trigger one immediate reward, and let the brand message ride on that moment of viewer control.

The real question is whether the interaction earns enough memorability to justify the added production. If the payoff is not instant and on-message, do not build it. Because the audience causes the outcome with a simple touch, the message sticks.

Practical patterns for interactive print

One interaction, one reward. Do not overload the surface with too many modes.
Make the “how” obvious. A tap zone, a knock cue, a simple instruction. Then deliver instantly.
Use phones as infrastructure. If pairing adds depth, let the phone do what paper cannot, audio, saving, sharing.
Design for public confidence. People will only touch a poster if it feels safe, clean, and socially acceptable.

A few fast answers before you act

What is “conductive ink” doing in these posters?

It creates touch-sensitive paths on paper, so taps or touches can be detected and mapped to actions like playing audio.

Do these posters need special printing like QR codes?

They still require specialist production, but the interaction can be integrated invisibly into the design. The poster itself becomes the control surface rather than carrying visible codes.

Why add Bluetooth to print?

Bluetooth allows paper to trigger sound through a phone or external speaker, which is essential when the content is audio or when you want richer layers than print can carry.

What makes an interactive poster feel “worth it” to a passer-by?

Immediate payoff and low friction. If the result is instant and satisfying, people will try it. If setup or pairing is slow, they walk past.

Where does this format fit best?

In environments where people have dwell time and curiosity, festivals, transit hubs, retail windows, office interiors, and brand experiences where interaction is socially normal.

Restaurant of the Future: AR Dining

The restaurant of the future is a technology experience

Restaurants of the future are no longer defined only by food, service, or ambiance.

They become technology-driven environments, where digital interfaces blend directly into the dining experience.

Smartglasses, augmented reality, gesture-based interfaces, customer face identification, avatars, and seamless wireless payments begin to coexist at the table.

The result is not a single gadget. It is a fully integrated experience.

When dining becomes augmented

In the restaurant of the future, the menu does not need to live on paper or even on a phone.

Information can appear in front of the guest through smartglasses or augmented displays. Dishes can be visualized before ordering. Nutritional details, origin stories, or preparation methods can surface on demand.

Gestures replace clicks. Presence replaces navigation.

The dining experience becomes interactive without feeling mechanical.

Identity replaces interaction

Face recognition and customer identification change how restaurants think about service.

Returning guests can be recognized instantly. Preferences, allergies, and past orders can be recalled automatically. Avatars and digital assistants can guide choices or explain dishes without interrupting human staff.

The restaurant adapts to the guest, not the other way around.

Payment disappears into the experience

Wireless payment technologies remove the most artificial moment in dining.

There is no need to ask for the bill. No waiting. No interruption.

Payment happens seamlessly as part of the experience, triggered by confirmation, gesture, or departure. Money moves, but attention stays on dining.

Mirai Resu. Japan’s restaurant of the future

To illustrate this vision, a short video from Mirai Resu in Japan shows what a fully integrated restaurant experience can look like.

Smartglasses, augmented visuals, gesture-based interaction, avatars, and invisible payment mechanisms come together into a single flow.

This is not a concept mock-up. It is a concrete glimpse into how dining, technology, and experience design merge.

In hospitality experience design, technology only “wins” when it fades into the flow and makes the human experience feel more effortless.

In experience-led hospitality brands, the winning AR layer is the one that keeps guests present while the service logic runs quietly in the background.

The real shift. Experience over interface

The most important takeaway is not the individual technologies. It is the shift away from explicit interfaces toward ambient interaction. By ambient interaction, I mean in-context cues and hands-free inputs that let guests act without hunting through screens. Restaurants should use this pattern to remove friction in ordering and paying, not to turn the table into a device demo. The real question is whether the tech can disappear enough that guests remember the meal, not the UI. Because the interaction happens in the moment and stays tied to the table, it keeps attention on dining, which is why it feels like hospitality rather than software.

Extractable takeaway: If an experience needs a screen to be understood, it is still an interface. The closer interaction stays to the real-world moment, the more it reads as service.

Steal this from AR dining

Prototype the full flow, not a feature. Order, identity, assistance, and payment should feel like one service journey.
Keep interaction in-context. Use gestures and overlays only when they reduce steps and keep guests present.
Make personalization explicit and optional. Recognition only lands when guests understand the trade and can opt out.

A few fast answers before you act

Is this about replacing staff with machines?

No. The value is removing friction so staff can focus more on hospitality and less on transactional steps.

Why does augmented reality matter in dining?

It can add information and interaction in-context, without pulling guests out of the moment or forcing phone-first behavior.

What does the Mirai Resu example actually demonstrate?

It demonstrates orchestration. Multiple technologies can be combined into one coherent service flow, rather than isolated gimmicks.

Where does “customer identification” fit in this vision?

It enables recognition on approach and service personalization, but it only works when guests understand the trade and feel in control.

What is the design principle to steal?

Design for experience continuity. Keep attention on dining, and make technology support the flow rather than interrupt it.
