Gaze-based web search: The impact of interface design on search result selection

This paper presents a study which examined the selection of Web search results with a gaze-based input device. A standard list interface was compared to a grid and a tabular layout with regard to task performance and subjective ratings. Furthermore, the gazebased input device was compared to conventional mouse interaction. Test persons had to accomplish a series of search tasks by selecting search results. The study revealed that mouse users accomplished more tasks correctly than users of the gazebased input device. However, no differences were found between input devices regarding the number of search results taken into account to accomplish a task. Regarding task completion time and ease of search result selection only in the list interface gaze-based interaction was inferior to mouse interaction. Moreover, with a gaze-based input device search tasks were accomplished faster in tabular presentation than in a standard list interface, suggesting a tabular interface as best suited for gaze-based interaction
