Sometimes a simple questionnaire or survey won’t get the job done when performing usability tests for websites. How certain elements on the page catch your gaze and how information flows are important concepts to consider.
This video by Tobii Research & Analysis allows you to dig deeper in usability testing with their eye tracking usability test demo. The entire usability test is built into the hardware, which includes an eye tracking camera, recorder, keystrokes, and mouse clicks.
The eye tracking data is converted into a directional heat map, which shows where the participants are looking, how long they look there, and where their gaze moves next. Surveyors may observe and analyze the data in real-time. The heat map sequences, along with the recorded data, can then be used to improve the design of the website.
