“For the designers, it’s so obvious, they worked and designed the product. But then we realize that for the users, the instructions are sometimes not logical at all” (Nathalie Korbee)
In the user context of the Oxylog, very specific needs became clear while interviewing the primary users. It appeared that a mobile ventilator is used under extreme conditions. For example by rescue professionals in situations where every second counts and there is no conditioned hospital environment. Despite being obviously a very reliable device, it should also work very intuitive and needs to comply with the special requirements regarding the mobile use. By means of user testing we could iterate in a short period of time towards a solid set of requirements, that where in a later stage checked once more in further user testing.
There are various tools available to facilitate user understanding. A tool we often use is interviewing real users where we apply our years of experience to get to the core of the needs and issues. With the gathered insights we can set-up user testing to check assumptions and possible design directions in practice, in an early stage of the product development process.
Once we have very sharp what provides the best user journey, we can blend this in the integral design, since also technical functionality, a product appearance that matches both brand and product identity and a proper cost-price should be covered.
