Since June 2010, I had seen smile detection technology used in vending machines and Facebook apps to create innovative engagement with target audiences.
Now, in this example, KPT in Switzerland decides to show that it has the happiest health insurance clients. To demonstrate that, they create Smileball, a pinball machine controlled by smiles.
Unlike normal pinball machines where the two paddles are controlled by buttons on either side, Smileball uses motion sensing technology to detect changes in a person’s smile and map that input to the respective paddles. By playing the game, participants get a chance to win a trip to a comedy show in New York.
A pinball machine that rewards the emotion it wants
The twist is that the game cannot be mastered by tense concentration. You need to keep smiling. That forces the behavior the brand wants to claim, and it makes the proof visible to anyone watching, because the input is literally on the player’s face.
How the mechanism works
The machine replaces buttons with a camera-based smile input. Smile more on one side and the corresponding flipper becomes easier to trigger. Relax your face and you lose precision. The interface quietly trains you into the brand message through play, not persuasion.
In Swiss health insurance marketing, turning an intangible promise like “happier customers” into a visible, shared moment can outperform any satisfaction statistic.
The real question is whether the interface makes a soft brand claim believable in public.
Why it lands
It is self-explaining, socially contagious, and it creates a public demonstration loop. People walk up because it is a pinball machine. They stay because it behaves differently. The crowd laughs because the control method is human and slightly absurd. In the end, the player’s smile becomes the performance, and the brand gets credit for orchestrating it.
Extractable takeaway: If your proof point is an emotion, design an interaction where that emotion is the input. When the audience can see the input in real time, the claim stops sounding like marketing.
What health brands can steal from Smileball
- Make the proof visible to bystanders. Spectators are your free distribution channel.
- Replace a standard control with a brand-relevant one. The control method is the message.
- Keep the first 10 seconds obvious. If people do not “get it” instantly, they will not try.
- Add a lightweight reward. A prize gives hesitant people a reason to step up.
A few fast answers before you act
What is Smileball?
A pinball machine where the flippers are controlled by changes in the player’s smile instead of physical buttons.
Why is smile-based control a strong branding choice for a health insurer?
Because it turns “happy customers” into a visible behavior. The player’s smile becomes proof in the moment, not a claim in copy.
Does this store or profile people’s faces?
The campaign is presented as in-the-moment smile detection used only to control the game interface. No storage or profiling is described in the original framing.
What is the biggest risk in executions like this?
Calibration. If the smile detection feels inconsistent, people assume the game is rigged and the experience collapses.
How could a brand apply this pattern without face-based input?
Keep the principle. Make the brand’s desired behavior the control input, then make that input visible so the claim proves itself in public.
