A dynamic approach of searching behaviour in webpages

International audienceThe visit of a webpage is driven by multiple bottom-up and top-down factors, such as the inner characteristics of the webpage, the goal or the user profile. In the present experiment, we studied the goal’s effects on participants’ visual behaviour while browsing 18 fully scrollable webpages. In order to achieve this, we asked them to carry out two kind of tasks: Free Viewing task and Target Finding task. Preliminary results showed the influence of the task on the scanpath length, the horizontal spatial dispersion of the fixations and the amplitude of the saccades. However, scanpath’s characteristics evolve during the navigation which highlight explore/exploit modes. Further analyses suggest that the scanpath’s dynamic is also influenced by the target detection
