The Utility of Mobile Eye Tracking Technology in the Forensic Analysis of Personal Injury
Early research on gaze patterns during human locomotion indicated that pedestrians tend to focus their gaze on the path 2 – 3 m ahead. More recent research in this area has utilized eye tracking technology to empirically assess eye movements during navigation in naturalistic environments. A similar approach to understanding personal injuries resulting in civil lawsuits has potential utility in the field of forensic human factors. The present study was conducted in the context of gathering empirical data to support expert opinions in a premises liability civil suit. Using a mobile head-mounted eye tracker, the gaze patterns of five individuals was assessed as they walked two paths covering the area where the plaintiff in the subject suit was injured. The results of this analysis indicated that, consistent with previous research, participants fixated the path ahead. Additionally, the duration of fixations on their final destination tended to be longer than fixations on other objects or areas in the forward view. The present study demonstrates the utility of empirical analysis of conditions surrounding a personal injury using eye tracking technology.
