Coca-Cola: Chok Chok

Mobile and creative thinking can come together to create really compelling marketing campaigns. In this example, Coca-Cola Hong Kong created a “Chok Chok” mobile app that turned the viewer’s smartphone into a remote control for their TV ad.

To collect the Coca-Cola bottle caps that appeared on the TV screen, viewers had to swing their phones when the ad came on. Those who successfully managed to swing and collect were instantly rewarded with prizes that included cars, sports apparel, credit card spend value, travel coupons and movie tickets.

As a result the campaign was seen by 9 million people and the app got over 380,000 downloads.

The real question is whether your second-screen idea creates a one-step action people can do instantly when the media moment appears.

For those wondering, the bottle cap collection was enabled through the audio signal of the ad, which triggered the application and synced the user’s motion with the ad. The accelerometer in the phone was also used to assess the quality of the motion. Together they were used to catch the bottle caps virtually.

However as far as I know, Honda in the UK was the first to pioneer this kind of an interactive TV ad, even though it did not receive results like Coca-Cola.

In mass-reach consumer campaigns where TV attention and smartphone use overlap, audio-synced interactivity can turn a passive spot into a short participation window.

Why this works so well

It works because it gives the viewer control in a way TV usually does not. Here, “viewer control” means one deliberate physical action that directly drives what you get from the ad. Because the ad’s audio triggers the app and the accelerometer judges motion quality, the “catch” feels causally tied to the on-screen moment instead of feeling random.

Extractable takeaway: If you want participation in real time, design a one-second action that maps cleanly to an on-screen event, then make the feedback and reward immediate.

  • Viewer control is the hook. The ad is not just watched. It is “played” through a simple physical action.
  • Timing creates urgency. You have to act when the ad is live, which turns media time into a moment of participation.
  • Feedback is immediate. You swing, you collect, you win. The loop is easy to understand and easy to repeat.

Steal this second-screen loop

Start with a single, unmistakable behavior the viewer can do in one second. Then use a reliable synchronization trigger (here, the ad’s audio) and a sensor input (here, the accelerometer) to connect the phone action to what happens on screen. This is the right level of interactivity for broadcast media: simple action, obvious timing, instant payoff.

  • One-second action. Choose a gesture the viewer can do immediately when the spot starts.
  • Reliable sync trigger. Use a broadcast-carried signal to trigger the experience, such as the ad’s audio.
  • Sensor validation. Use the phone sensor input to assess whether the action quality is good enough to “count”.
  • Immediate feedback. Keep the loop legible: swing, collect, win.

A few fast answers before you act

What is Coca-Cola “Chok Chok”?

It is a Coca-Cola Hong Kong mobile app that synchronizes with a TV ad and lets viewers swing their phones to collect on-screen bottle caps for prizes.

How did the app sync with the TV ad?

The app used the audio signal of the ad as the trigger, then aligned the on-screen moments with the user’s motion so “collection” happened at the right time.

What role did the accelerometer play?

The accelerometer assessed the quality of the swinging motion, helping determine whether the viewer “caught” the bottle caps virtually.

What is the main takeaway for interactive TV and second-screen work?

Make participation effortless, tie it to a tight timing window, and reward the action immediately so the viewer feels impact in the moment.

Turismo de Portugal: Cobblestone QR Codes

To get into the minds of tourists, Turismo de Portugal decides to fuse QR code technology with Portugal’s historical cobblestone tradition. The result is described as the first QR code made from Portuguese cobblestones.

The first QR code is embedded into the city ground in Lisbon, followed by an installation in Barcelona. Reported write-ups describe the campaign as successful enough to spark plans for similar cobblestone QR codes in other cities such as Berlin, Paris, Tokyo, New York, Vienna, Goa, Lima, and Oslo.

When street craft becomes the interface

The mechanism is simple. A familiar tourist behavior, looking down at the street and looking for cues, is turned into a scan trigger. The QR code is physically “native” to the place because it is built using the same black-and-white stone patterns people already associate with Portuguese streets, especially in historic areas like Chiado.

In destination marketing and city tourism promotion, bridging physical street culture to mobile content is a reliable way to convert foot traffic into deeper engagement. Destination brands should treat the street as the interface, not just the backdrop.

In European destination marketing, the most scalable activations turn street-level cues into a clear mobile doorway.

Why this lands with visitors

It does two jobs at once. It signals “authentic Lisbon” through material and craft, and it gives the tourist an immediate next step through their phone. The real question is how you turn a place’s own cues into a frictionless next step without making it feel like advertising. Unlike a poster or a billboard, the code is part of the ground people are already walking on, so discovery feels like finding something, not being targeted.

Extractable takeaway: If you want mobile interaction in public space, embed the call-to-action into something the place already owns. Local texture first, technology second. The scan should feel inevitable, not imported.

What to steal for your own place-based activations

  • Make the trigger belong to the environment. Use local materials, patterns, or rituals so the interaction feels contextual.
  • Design for tourist attention spans. The best street interactions reward a 5-second decision, not a long explanation.
  • Use “discovery” as the media buy. When people feel they found it, they are more likely to scan, share, and talk about it.
  • Plan for maintenance and legibility. Outdoor codes live or die based on wear, lighting, contrast, and camera-readability.

A few fast answers before you act

What is the Cobblestone QR idea in one sentence?

A QR code built into the street using Portuguese cobblestones, so tourists can scan a piece of the city itself to access content.

Why does making a QR code “physical” matter?

Because it turns a generic tech behavior into a place-specific experience. The scan feels like interacting with Lisbon, not with a random sign.

What makes this different from putting a QR code on a poster?

Placement and meaning. A poster is rented space. A street pattern is owned space. The medium carries authenticity before the message even loads.

What should the QR code open to?

A fast-loading mobile page that confirms you are in the right place and offers one clear next step. If the page feels generic or slow, the “found it” magic disappears.

What is the biggest execution risk?

If the code is hard to scan or the content behind it is weak, the novelty collapses. The physical build earns attention. The mobile experience must repay it.
