from Think Aloud to Participatory AnalysisNielsen, Janni (København, 2004)[More information][Less information]
Abstract: Think Aloud is cost effective, promises access to the user’s mind and is the applied usability technique. But "keep talking" is difficult, besides, the multimodal interface is visual not verbal. Eye-tracking seems to get around the verbalisation problem. It captures the visual focus of attention. However, it is expensive, obtrusive and produces huge amount of data. Besides, eye-tracking do not give access to user’s mind. Capturing interface/cursor tracking may be cost effective. It is easy to install, data collection is automatic and unobtrusive and replaying the captured recording to the user and probing about her actions and thoughts open for participatory analysis.

On concurrent usability testingNielsen, Janni; Yssing, Carsten (København, 2004)[More information][Less information]
Abstract: 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.
