Abstract
The purpose of the present study was to develop a methodology to identify when a user is confused while using a product. Eye movements were measured to determine whether they reflect confusion while users completed tasks with two simulated devices. First, two devices that differed in subjective ratings of confusion were identified. Then eye movements and task performance were measured while experienced and inexperienced users conducted nine tasks with the devices. The relationship between eye movement and confusion measures depended on the task and the user group. Results provide a foundation for developing methods to identify and predict user confusion on the basis of eye movements, and ultimately to design products to avoid confusion.
