Aura is a concept I designed from a real brief, with names and details changed under NDA. The product is a set of microphones placed around the home. They learn what the house normally sounds like and flag what doesn’t fit, like glass breaking, a fall, or a loud noise when no one is supposed to be there. A system like this is listening all the time. Rather than hide that, I built the interface around the sound wave itself. My thinking was that people would find it easier to trust the system if they could see what it’s hearing, instead of a green icon saying everything is fine.
The logo is three rings for the range the sensor listens to, from near to far. Colour is kept for status: blue for live, green for all quiet, amber for attention and red for critical. Everything else stays grey.

The home screen is there to tell you quickly whether everything’s okay at home. The live wave sits in the middle with the current sound level under it, and anything that needs a look is listed on the right. When the house is calm, the screen stays mostly grey.

Each sensor shows its own wave from the last few minutes, so you can tell the rooms apart at a glance and see which one is active. Opening a sensor shows its full day, its details and its event log.

The day is shown as one continuous line of sound. Normal activity stays blue, and anything flagged is coloured by severity, from grey for low to red for critical, so a busy afternoon is easy to spot. Every flagged sound can be played back, so you can decide for yourself whether it was the dog or something worth checking.

The month view uses the same idea at a smaller scale. Each day gets a short wave, and days with critical events show up in red.
