Voice Chocolate

On Valentine’s Day, women in Japan record a voice message on their smartphone. That voice is transformed into a unique chocolate pattern, and a premium patisserie, Mont St. Clair, delivers the custom chocolates to the men they love. The recipient then uses a special app that recognises the AR markers in the chocolate, and the voice message plays back from the smartphone.

The campaign comes from Docomo (Japan’s largest mobile phone company) working with agency Hakuhodo. The business context is straightforward. Voice communication traffic falls sharply over the last 15 years, largely due to messaging apps. Docomo uses the ritual of Valentine gifting to make voice feel emotional and “worth using” again.

Why this works as mobile, packaging, and emotion in one system

This is not content about voice. It is voice turned into a physical artefact. The chocolate is both the gift and the interface. The phone becomes the capture tool. The app becomes the playback layer.

That combination matters because it closes the loop between human intent and digital capability. The message is not typed. It is spoken. It arrives as something tangible. Then it becomes audible again at the moment of receiving.

The pattern to steal

If you want to revive a behaviour that is losing ground, the structure here is repeatable:

  • Find a culturally accepted moment where the behaviour already makes sense, in this case Valentine gifting.
  • Convert the behaviour into a physical token people want to give and keep, not a disposable digital asset.
  • Use an interaction layer (AR, scan, app) that reveals the emotional payload at the right moment, for the recipient.

A few fast answers before you act

What is “Voice Chocolate”?

A Valentine concept where a recorded voice message is transformed into a chocolate pattern, delivered as a gift, then played back via an app that recognises AR markers in the chocolate.

Who is behind it?

Docomo in partnership with Hakuhodo, with chocolates delivered with help from Mont St. Clair.

What problem is it addressing?

Falling voice communication usage driven by messaging apps, by making voice feel meaningful again through gifting.

What is the core experience design move?

Turn a voice message into a physical interface, then use a scan-to-reveal mechanic so the voice returns at the moment of receiving.

BMW Christmas Safety Card

To wish customers a new year of safe driving, BMW, together with ad agency AIR and electronics company Selectron, creates a Christmas card meant to be hung in the car.

A micro-sensor is built into the card to measure driving behaviour and react with a spoken message, “Ho! Ho! Hooo! Just like Santa!”, when the car is driven unsafely. The sensor measures G-forces and reacts when the car accelerates too much, or when it brakes or drives too quickly through bends.

A Christmas card that behaves like a safety co-driver

This is not a decorative greeting. The card acts like a lightweight in-car safety layer. It listens for aggressive driving signals, then interrupts with a playful warning that is hard to ignore.

Why this fits the BMW M League audience

These limited-edition cards are sent to members of the BMW M League who recently buy their car and participate in the BMW Track Days. For that audience, performance driving is part of the identity. This card nudges safer habits without lecturing, because it speaks in a tone that feels seasonal and disarming.

The pattern to steal

  • Pick a behaviour you want to influence and measure it directly.
  • Embed the intervention into a physical object people will actually place in the environment.
  • Trigger feedback at the exact moment of behaviour, not later in an email or app.
  • Use a tone that makes the correction acceptable, so people do not reject it on instinct.

A few fast answers before you act

What is the BMW Christmas Safety Card?

A Christmas card designed to hang in a car, with a built-in micro-sensor that detects unsafe driving and plays a Santa-style voice warning.

What does the sensor measure?

G-forces. It reacts to strong acceleration, hard braking, and taking bends too quickly.

Who receives these cards?

Members of the BMW M League who recently buy their car and participate in the BMW Track Days.

What is the core idea in one line?

Turn a seasonal greeting into an in-car behavioural nudge that activates in the moment.

Tostitos Party Safe Bag

On Super Bowl Sunday 2017, Tostitos puts safety into the packaging. The limited-edition “Party Safe” bag can detect when you have been drinking, then helps you get home safely from the party.

The trigger is built into the bag itself. The bag is created by Goodby Silverstein & Partners and comes equipped with a sensor connected to a microcontroller calibrated to detect traces of alcohol on a person’s breath. If alcohol is detected, the sensor turns red and forms the image of a steering wheel.

Then it turns that moment into action. The bag provides a $10 off Uber code along with a “Don’t drink and drive” message. If you have an NFC-enabled smartphone, you can also tap the bag to call an Uber.

Why Tostitos ties this to the Super Bowl

The campaign starts from a hard, uncomfortable statistic. According to the US National Highway Traffic Safety Administration, 45 people are killed in drunk-driving crashes on Super Bowl Sunday 2015, nearly half of all traffic fatalities that day.

So the “Party Safe” bag frames itself as a practical intervention on the one day when party behaviour and driving risk collide at scale.

This is IoT packaging with a clear behavioural goal

The packaging is not a gimmick for novelty’s sake. It is packaging that nudges a specific decision at the moment it matters most. Do not drive. Call a ride.

The smart detail is the friction reduction. The message is immediate, the code is immediate, and the tap-to-request option removes even more steps.

The pattern worth stealing

If you work on connected experiences, the structure is reusable.

  • Put the sensor where the decision happens, not in a separate app.
  • Translate detection into a single, obvious next action.
  • Pair the behavioural nudge with a concrete incentive that accelerates compliance.

How does the bag detect drinking?

A sensor connected to a microcontroller is calibrated to detect traces of alcohol on the breath.

What happens when alcohol is detected?

The sensor turns red and forms a steering-wheel image. The bag provides a $10 off Uber code and a “Don’t drink and drive” message.

How does the Uber action work?

You can use the $10 off code, and NFC-enabled smartphones can tap the bag to call an Uber.
