Situated Design
|
|
Our article (Lottridge, Masson & Mackay, 2009) on designing for long-distance couples was significant for me because of the sensitivity needed when approaching the complex and nuanced design problem of intimacy. Also, we created and field-tested a functional solution, a huge challenge! We found that Technology Probes were a powerful method for field testing; they yielded design, technology and social science insights.
Generative Walkthroughs
|
Since 2006, Wendy Mackay and I have been collaborating on Generative Walkthoughs - a novel method to support the redesign phase of iterative design (Lottridge & Mackay, 2009). Scenario-based walkthroughs and focused brainstorming help designers generate design alternatives informed by key social science insights.

Usability Applications
Usability is a practical concern and activity that I enjoy and regularly revisit in my teaching, consulting and research. I tend to do consulting in the area of communication technologies, and research in driving and medical technology usability.
I worked as a freelance consultant and for the consultancy Vocalage.
My masters project was on individual differences in responding to interruptions in a driving context. We found that field dependent participants answered phone calls more quickly and with less consideration of the difficulty of the current driving situation than more field independent participants (Lottridge & Chignell, 2007).
During my masters and PhD, I collaborated with physicians, nurses and engineerings to build and test several medical applications. These papers describe the large usability study which found significant differences in user needs between the physician groups (Lottridge et al, 2004a; Lottridge et al, 2007).
