Publicis Israel and e-dologic are back with a new campaign for Prigat, a leading company in the Israeli fruit juice market.

This time they use innovative digital billboards called “Smile Stations” to send real-time messages at various train stations. The aim is to get passers-by to smile, and “like” the moment.

The mechanic: turn a Facebook message into a station moment

It starts on the Prigat Facebook Page. People send messages that are pushed to screens at train stations. Commuters walking by can approach the screen and press a physical “Like” button.

That button press triggers a simple payoff. The billboard captures the moment, then broadcasts the video back to the person who sent the message. Users who generate the most smiles win a prize.

In busy public transit environments, interactive out-of-home works best when the action is obvious, the feedback is immediate, and the reward is shareable.

Why it lands: it makes public emotion measurable

Most out-of-home asks for attention. Smile Stations asks for a reaction, then turns that reaction into proof you can send back to the originator.

Extractable takeaway: If you want participation at scale, close the loop. Let a remote user trigger a real-world moment, let a passer-by respond with one physical action, then send that response back as a personal artifact the originator can keep and share.

Reported figures put this at over 10,000 messages sent to station screens, with thousands of people responding by hitting the Like button.

What the brand gets from this

The real question is whether a public display can turn a remote social prompt into a personal moment worth sharing.

This is stronger than passive digital out-of-home because the physical Like button reduces effort and the returned video turns a fleeting reaction into a personal memory both sides can own.

The campaign does not just generate impressions. It creates a two-sided interaction where both parties feel like they caused something to happen. That is a stronger memory structure than “I saw an ad”, especially in a context as repetitive as commuting.

What to steal for your own social-plus-out-of-home activation

Design a one-step physical interaction: one big button beats a complicated interface in public space.
Make the response visible: the passer-by should understand instantly that their action “counts”.
Return a personal artifact: sending the video back is what turns participation into sharing.
Gamify without friction: “most smiles wins” is a clean mechanic with no explanation overhead.
Pick locations with dwell time: stations work because people pause, look up, and wait.

A few fast answers before you act

What is a “Smile Station”?

It is an interactive digital billboard at a train station that displays user-submitted messages and invites passers-by to respond by smiling and pressing a physical Like button.

What makes this different from a normal digital billboard?

It is two-way. Remote users trigger messages, commuters respond physically, and the response is captured and sent back as video, creating a closed feedback loop.

Why include a physical Like button?

Because it removes friction. A single, tangible action is faster and more intuitive than asking people to pull out a phone, scan, or type.

How do you measure success for an activation like this?

Message volume, unique senders, Like-button presses, response rate per message, video shares by originators, and dwell time around the screen locations.

What is the main execution risk?

Latency and unclear feedback. If the system feels slow or people are unsure what their button press did, participation drops quickly in a commuter setting.

Prigat, a leading company in the Israeli fruit juice market, launched one of the more inventive Facebook mechanics of its era. It invited people to squeeze real orange juice by doing something absurdly simple. Smile at your webcam.

The idea was packaged as “User Generated Orange Juice (UGOJ).” A Facebook application that translated user participation into a physical outcome you could actually watch.

The mechanism: your smile triggers a real machine

A custom Facebook app developed by Publicis E-Dologic used webcam-based smile detection to trigger a real, oversized juicer. When the app detected a smile, it activated the juicer and squeezed fresh oranges. Users could watch the machine live 24/7, so the cause-and-effect was visible rather than implied.

Campaign coverage also described a personalization touch where the participant’s name appeared on the machine during use, and that the resulting juice was directed to a charity choice.

In social platform marketing, physical proof loops outperform abstract engagement prompts because they give people a reason to believe and a reason to share.

Why this lands

This works because it turns a universal emotion into a measurable input. Smiling is effortless, socially contagious, and camera-friendly. The live feed makes the outcome undeniable, and that “I did this” ownership nudges people to recruit friends so their smiles compound into more visible results.

Extractable takeaway: If you want participation at scale, connect a low-friction action to a real-world output that people can witness in the moment, then make sharing feel like extending the impact, not like promoting the brand.

What Prigat is really doing

The campaign turns Facebook from a place for liking into a place for doing. The real question is how to turn a passive social audience into a participant who can see, trust, and share the brand experience. This is stronger than a standard Facebook giveaway because the proof is built into the interaction itself. It converts attention into a visible production line, then uses the live stream as credibility and the smile photos as distribution. Prigat gets warmth by associating the brand with positive emotion and generosity, while the machine supplies a visible proof point that keeps the story believable.

What to steal from the Prigat participation loop

Design a simple input. The easier the action, the more likely people repeat it and recruit others.
Show the output live. A real-time feed reduces skepticism and increases share-worthiness.
Make participation legible. If the user can see their effect immediately, they trust the loop.
Attach a social good endpoint. A charity destination converts novelty into meaning.

A few fast answers before you act

What is “User Generated Orange Juice” (UGOJ)?

It’s a Facebook app activation where users smile at a webcam and trigger a real juicer that squeezes fresh oranges, visible via a live stream.

How does the smile activation work?

The app uses webcam-based smile detection to decide when to trigger the juicer. The user’s action becomes the on-switch.

Why include a 24/7 live view of the juicer?

It provides proof. People can watch the result of participation, which increases trust and makes the story easier to share.

What kind of results were reported?

Reported results include around 30,000 new likes, over 20,000 photos uploaded, and roughly 40,000 oranges squeezed.

What’s the key risk if you copy this concept?

Trust and privacy perception. You need clear, simple communication that the webcam is used only to detect the smile for the interaction, and that the experience is safe and transparent.
