I had the honour of taking part in a panel session discussing How Does Accessibility Fit into Today’s Usability Practice? at the Usability Professionals’ Association Conference (UPA 2010) in Munich last week. The session was organised by Shawn Henry of the W3C Web Accessibility Initiative and provided an opportunity to debate the challenges of promoting and supporting accessible ICT design within a wider usability context. A number of interesting discussion points emerged – here are my reflections on the panel session.
One of the great things about my job as a researcher with a focus on accessibility and usability is that I can happily justify going all reflective on an everyday event, wondering why it happened, and what could be done to change it in the future – especially if it involves some user interface design quirk or flaw. Recounting this can provide valuable insight and encouragement to improving the quality of interface design – just Ask Tog!
Earlier this week I presented a very influential paper to our reading group: Damaged Merchandise? A Review of Experiments that Compare Usability Evaluation Methods, by Wayne Gray and Marilyn Salzman. Reading it again reminded me why it had such an impact on me first time around, and I thought I’d share my views on why I think it’s such a worthwhile read, even 11 years after it was published.
The paper critiques 5 prominent (i.e. published in prominent academic publications and subsequently cited) studies that compared different Usability Evaluation Methodologies (UEMs). It found that for each study the experimental design casts doubt over the validity of the conclusions made.
