Our usability testing computer uses a 19” monitor integrated with the Tobii X120 eye-tracking system, which can be used to detect and collect participant eye-gaze data during testing. The eye-tracker samples the position of the user’s eyes on an average of every 25ms (i.e., 60Hz) and is characterized by the unobtrusive addition of the eye-tracking hardware (e.g., high resolution camera and near infra-red light-emitting diodes) to the monitor frame. This design aspect helps promote more natural user behavior by not placing unnatural restrictions on participants (e.g., helmets, head-rests).
Eye tracking measures include:
- Overall number of fixations
- Number of fixations to specified Areas of Interest (AOI)
- Overall average fixation duration
- Average fixation duration to each AOI
- AOI fixation order
- Total AOIs fixated upon
- AOI transition density
- Spatial density of fixations
The SURL team will work with you to identify which portions of your website are most amenable to eye-tracking.
