The team started by
exploring the existing product and researching competitor products from around the
world. As well as this, the team
investigated user environments and identified potential trends for the future
of these devices.
From the usability
studies, IDC realised a key area for improvement was the humidification system,
which offered a great opportunity for simplification. The device relied on a water tank to humidify the filtered air, but this meant designing a solution that minimised spillages and was convenient for the user.
