The experiment simulated common web search type: the purchasing of tickets on a flight-booking site. The task was to search for return plane tickets within certain given parameters. Within-subjects factors were: (a) the webpage design which influenced the search process: simultaneous or subsequent display of flight segments; (b) the task complexity which exerted different working memory loads. Each participant (n=10) carried out 32 tasks (320 trials in total). The speed and accuracy of the search and the parameters of eye and cursor movement were measured. The results showed that the time taken and the dwell time spent in the key area of interest depended more on the task complexity. On the other hand, correlation of movement between eye and cursor was influenced only by the webpage design. The average fixation duration was influenced by both factors; it was grater in more complex tasks and with subsequent displays of flight segments. The study was supported by the RFBR № 17-06-00652.
