Thinking-aloud in user interface design: a method promoting cognitive ergonomics

The thinking-aloud method has been used successfully in user interface research. The present study investigates the application of the method for user interface design. The study is based on interviews with nine systems designers who had used the method in design practice. Their application of the method was in general very successful. This paper focuses on a unique property of this method: its inherent promotion of cognitive ergonomics due to the timely, genuine and applicable feedback to the designers in the design context.
