What Kind of Information does an HCI expert want?

Janni Nielsen and Carsten Yssing

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.
