A poster informs. A screen displays. A campaign speaks. But what if a public surface could do something more? What if it could ask a simple question, capture a lightweight response in the moment, and connect people to useful next-step information? That is the idea behind **Ambient Feedback**, a new interaction layer we have been developing at WOM.fm. Imagine a bus stop poster during a heat wave. Instead of only warning people about extreme temperatures, it asks a simple question: **How does the heat feel where you are right now?** A passerby scans the code, hears a short prompt, taps one of three simple faces, and is then linked to heat safety guidance. It is a very small interaction. But it changes the role of the surface completely. The poster is no longer just broadcasting a message. It is listening. That matters because many important campaigns are not only about awareness. They are about **response**. Public health campaigns need to know how people are feeling. Safety campaigns need to understand perception on the ground. Local communication works better when it invites participation, not just attention. Ambient Feedback is designed for exactly these moments. It adds a lightweight response layer to posters, screens, and other physical surfaces - simple enough for quick participation, flexible enough to connect feedback with useful next-step guidance. To explore the idea in a public-interest setting, we created [a simple public demo called **Heat Check**](https://wom.fm/700). It shows how a Ministry of Health-style campaign could turn a bus stop poster into a listening point: - ask a question - capture a lightweight in-the-moment response - connect people to trusted information And the same logic goes far beyond heat. It could be used for: - public health campaigns - neighbourhood perception - public safety communication - local service feedback - DOOH and OOH campaigns - brand research and message testing In other words, the physical world does not have to remain a one-way media layer. Surfaces can do more than display messages. **They can listen back.** **Where could this make communication more useful in your context?** ## Share this post [mailto:https%3A%2F%2Fwww.wom.fm%2Fblog%2Fwhat-if-public-surfaces-could-listen-back](mailto:https%3A%2F%2Fwww.wom.fm%2Fblog%2Fwhat-if-public-surfaces-could-listen-back) ## Keep reading ### [![Two women in a village savings group listening to digital financial literacy education audio on their mobile phone.](https://www.wom.fm/hs-fs/hubfs/digital_financial_literacy.jpg?width=2400&height=1254&name=digital_financial_literacy.jpg) Product Stewardship Customer Education Digital Financial Literacy Financial Inclusion Is Not Enough: Why Digital Financial Literacy Matters for Women](https://www.wom.fm/blog/digital-financial-literacy-women) ### [![](https://www.wom.fm/hs-fs/hubfs/BASF_Blog.jpg?width=2400&height=1288&name=BASF_Blog.jpg) Product Stewardship Customer Education Last-mile Communication Who are we really designing worker safety communication for?](https://www.wom.fm/blog/worker-safety-communication-last-mile) [![wom\_logo2](https://www.wom.fm/hs-fs/hubfs/wom_logo2.png?width=160&height=49&name=wom_logo2.png "wom_logo2")](https://www.wom.fm) **WOM.fm - guide, engage, listen** - [Insights](https://www.wom.fm/blog) - [Pricing](https://www.wom.fm/en/pricing) - [Contact](https://www.wom.fm/contact) [Privacy Policy](https://www.wom.fm/privacy-policy) · [Legal](https://www.wom.fm/legal) · © 2026.
