Abstract: Thinking Aloud Thinking Aloud is the most commonly used technique used to test users´ interaction with computers. The assumption is that Think Aloud gives access to what goes on in the users´ minds. However, interfaces are multi modal and play heavily on user´s visual perception. Reflecting upon Think Aloud (TA), we ask the question: what happens when users are required to verbalise their visual perceptions and interactions? We argue that TA may have a disruptive effect, suggesting that other techniques be considered. With a theoretical distinction between focal and subsidiary awareness and a focus on the sense making process, we develop a frame for test of user´s visual interaction which rely on the coordination between hand/mouse and eye/cursor.
Keywords: Think Aloud; visual perception; interaction; test
