Creating Expert Level GUIs for Complex Medical Devices

Graphical User Interfaces are so pervasive and have so many different design intents that it can be hard to see the norms and evolution of norms being applied over the past couple of decades. In medical devices, more than most, tradeoffs between safety, effectiveness and pleasure-to-use, dominate the design efforts.
Much focus and debate has been applied to paradigms of “simple yet effective” in GUI design. The most commonly cited ideals in the Apple eco-system and skeuomorphic design concern themselves with the novice user and technology adoption. But not all products are designed for the novice user.
For UIs that expose advanced or unstructured feature sets to the user, the normative approach has been to compromise on the simplicity to extend the functionality. But such an approach can be incremental and muddled where a better approach might be cogent redesign.
We will explore the evolution of a life-saving lung transplant medical device from Tevosol that implements an expert-level GUI for clinical users. Focus will be on lessons learned and the design principles ultimately chosen.
