Gaze-based web search
Yvonne Kammerer, Wolfgang Beinhauer · 2010
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 gaze-based 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 gaze-based 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.
