This morning, during a walk, I came across a public display board showing live air pollution data.
“PM2.5 58 µg/m³” Then it switched to ozone levels. Then NO₂. Then more scientific terms.
And that got me thinking: This is a perfect example of how information can be technically correct but still fail the user.
Most people passing by won’t know: • What PM2.5 means • Whether 58 is dangerous • If it’s safe to exercise outside • Or if they should simply wear a mask
The data exists. The communication doesn’t.
Good UX isn’t just about apps, websites, or shiny interfaces. It’s about translating complexity into clarity. Especially in public experiences where everyone, regardless of background, should understand what’s being communicated.
Imagine if the board instead said:
🟢 Air Quality: Moderate 😷 Sensitive groups should wear masks 🏃 Outdoor exercise: Okay in moderation
Same data. Far better experience.
Design is not only about displaying information. It’s about making information understandable.
