# Keep - Subway Station -- Breath-Activated Interactive Wall

> For Keep, the fitness app, MLABART created an interactive wall in a subway station. Commuters blow on the wall and the year's keywords appear where their breath lands, turning a New Year wish into a physical gesture made in passing.

## Scenario

Keep, the fitness app, timed this subway-station installation to the New Year. A subway wall reaches commuters who are passing through, so the interaction had to stop people who had no plan to stop.

## Interaction

The wall senses breath: blowing on the surface reveals the year's keywords where the breath lands, so the wish is made with a physical gesture rather than typed or tapped.

## Technologies

- Sensor Interaction
- Interactive Installation
- Digital Content Production

## Marketing value

A subway wall reaches a commuter audience that no venue can gather. Breath as the input is unusual enough to stop people who had no intention of stopping.

## Why brands choose this approach

- A subway wall reaches a commuter audience no venue can assemble, at a moment when people are already waiting.
- Breath as the input is unexpected enough to stop someone who had no intention of stopping -- that is the whole job in transit.
- The gesture matches the brand: a fitness app asking for breath, not a tap.
- No enclosure, no staff, no queue -- it works unattended in a space with heavy footfall and no floor area to spare.
