Is Eye Tracking the Next Step in Usability Testing?
Lynne Cooke · 2006
In usability testing, eye tracking has been used to gain insight into human behavior that may not be available through observation or think-aloud protocols. HCI researchers have suggested that the eye movement measures of fixation duration and fixation frequency are related to cognitive processing ease/difficulty and search efficiency/inefficiency. This study investigates whether the connection between these eye movement measures and their respective cognitive activities can be confirmed through user self-reported data. The findings show that fixation duration and fixation frequencies are interdependent measures. Analysis of the self-reported data indicates that although users' responses are limited in what they reveal about cognitive processes, the responses generally confirm the eye movement measures
