Interaction Designer / Usability Engineer
at Philips Healthcare

Philips sketch

Between October 2011 - October 2012 I worked as a usability engineer in Philips Healthcare. Contributing to the interaction design of a major healthcare platform was my main task. I also co-authored user interface standards and conducted usability tests on medical settings in the Netherlands, Germany and Belgium. I really enjoyed working at Philips and it was a pleasure to feel that my work had a direct impact to the medical industry! You can find below some examples of my work in Philips. Some images are processed for confidentiality.


Initially a set of requirements was created, established through discussions with the medical professionals and application experts. These were the basis for designing any product.

Usability test setup

in Philips Healthcare Hamburg.

Interfaces for a Computed Tomography acquisition unit

Two interfaces of a Computed Tomography acquisition unit. I conducted a test comparing their usability in hospitals in Belgium and the Netherlands.

Philips touch interface

I authored a UI standard on the use of touch in Philips medical devices. The picture depicts a grid of appropriate size for touch interaction over a typical acquisition device interface.

Print function storyboard

This is a storyboard I created depicting the workflow of the print function in a medical platform for image viewing. These designs were demonstrated and discussed with different stakeholders from Philips before being tested in the field.

Storyboard of the import function

This is the storyboard of the import function I created for the same platform.

Storyboard of search function

And this is a snapshot of the search function I designed.

The resulting interface was implemented by Philips developers and incorporated the functions me and my colleagues specified.
