This product was born out of a real need: the plastic band for the Fitbit isn’t secure; the devices fall off easily and thus the biggest complaint is that people lose them.
Working with Alec Ramsay and John Wana at Front Seat, our iterative design process relied heavily on active prototyping. We made several versions of the interface and tested different visual feedback methods while hiding Fitbit devices and trying to find them with an iPhone prototype.
Our goal was to provide helpful feedback to find a lost device, yet not be too instructive since we knew we couldn’t be definitive due to numerous constraints and variables. For example, a bluetooth signal provides a way to detect a lost device if the battery is still charged, but giving explicit directions in the app isn’t possible since the signal can emit through walls, ceilings and floors; but not through specific materials like steel.
The winning solution employs a heartbeat analogy, showing a vertical line for the signal detection event and an additional line going directionally up or down as the app gets closer or further from finding the device.
The wireframes here show multiple options considered. The final design is shown here as screenshots from the Fitbit Finder app, downloadable from the app store.
