Graphical User Interfaces
We craft, test, and build graphical user interfaces (GUIs) with extreme care, because sometimes a life may depend on it.
Maddison specialises in the development of technical interfaces – particularly medical user interfaces, where performance is critical and the development process is heavily regulated.
Interfaces are developed with designers and experts in human factors. This is done to ensure the interfaces are not merely aesthetically pleasing but are intuitive to use, forgiving, and most importantly, safe. The objective is always to ensure that no harm can come from imperfect design or unintended consequences.
Our process
Throughout the development process, we employ digital prototypes and follow iterative "build-test-learn" cycles. At each stage, we conduct usability and human factors testing to continually refine and improve the interfaces.
To ensure our interfaces are technically feasible, we work with software teams to establish the operating environment and any constraints on the interactions. We then work to ensure the interface can be coded and debugged before final (summative) testing.
The image to the right shows a prototype GUI for M-Mark, a stroke rehabilitation device, being user tested.
Interface design principles
- First, do no harm.
- Define the governing regulatory requirements.
- Involve users and test the device with them early.
- Understand and use existing medical conventions.
- Develop with successive 'build–test–learn' loops.
- Design the interface to be intuitive.
- Use poka-yoke principles.
- Design in redundancy.
- Design in forgiveness.

Examples
Genomtec
Genomtec is a new point-of-care in vitro diagnostic device. It is designed to be used by a broad category of front-line healthcare workers, such as GP’s, nurses and pharmacists. Maddison developed the GUI and the integrated “walk-through” interactive IFU’s. Read more about Genomtec.
United Imaging
United Imaging, a multinational medical imaging provider, collaborated with Maddison to develop a unified graphical user interface (GUI). This GUI aimed to provide a consistent experience across their various imaging technologies and equipment. The software was designed to seamlessly work with the diverse range of imaging technologies and equipment.
Phagenesis
Maddison concentrated on creating a user-friendly interface. This intuitive graphical user interface (GUI) was specifically designed to be easily navigated by both experienced users and novice Speech and Language Therapists, fostering efficient learning and safe usage. Read more...
SLE 6000
The SLE 6000, a specialized infant respirator, serves as a notable instance in the evolution of a crucial medical Graphical User Interface. Maddison meticulously developed and tested the interface in collaboration with the client and users.
