I have decided to refresh my approach to blogging (yet again). There are a couple of main drivers for this.

Getting to the root causes of usability errors and accessibility problemsUser Vision

Perception–Cognition–Action (PCA) analysis is a method of uncovering the root causes of usability errors and accessibility challenges in systems. By understanding these underlying issues, designs can be enhanced in order to avoid hazardous situations and cater to a wide array of user needs.

The approach is particularly recommended for medical devices, and is described in the international standard IEC 62366 on the application of usability engineering to medical devices. But this powerful technique can go so much further than that. It can help us understand how to improve usability and accessibility for a wide range of products.

My article for the User Vision website describes how the Perception–Cognition–Action approach works, how it aligns with established accessibility best practice, and how we at User Vision have applied it to transform a complex medical system used by both patients and healthcare practitioners.

I will also be speaking about the technique at this week’s UX Edinburgh meetup, which is an accessibility special in recognition of Global Accessibility Awareness Day. If you are around on Thursday 16 May at 18:30, it would be great to see you there.

Breakfast briefing — Behavioural science: Approaches to improve user experienceUser Vision

Join me for a virtual breakfast session where you will learn about the links between behavioural science and user experience. We will also introduce some behavioural science frameworks and models you can adopt to improve your user research and design work.

It takes place online on Tuesday 7 March at 8:30am.

Update: Slides for this session are now available:
