What Kind of Information does an HCI expert want?
Abstract: Working with usability techniques, with focus on how a
given technique enables data capture made us ask the question: What kind of
information is it an HCI expert want from the user when conducting a
usability test? We answer the question by discussing two techniques both
relying on concurrent data. Think Aloud is one of the most frequently used
techniques and almost an institution in itself. Eye-tracking is new in
usability testing and still at an experimental level in HCI. We reflect
critically upon the two obtrusive techniques. We discuss the usability of
concurrent data capture, suggesting participatory analysis and
retrospective verbalisation as a possible step in usability testing.
