We (Design Researchers at the People and Systems Lab, QUT) do a lot of work with video, collected in our usability lab and in the field, but we rarely show that video to other people. We’ve found that by turning video into visualisations it’s easier to compare different videos. When we have visualistions that “sit still” the patterns of use that people engage in become more apparent. In order to make the video “sit still” we use the common technique of coding behaviours and activities that we are interested in observing.
In this presentation Dr Ben Kraal will show some of these visualisations and talk about how they work and how we’ve used them to develop insights into the activities we observed.
In particular this presentation will show how we used these visualisations to understand the different levels of expertise shown by nurses doing compression bandaging to treat venous leg ulcers.
