Evaluation of mobile eye tracking for forensic analysis of pedestrian falls

摘要

The forensic analysis of falls is most commonly reliant on the application of generalized non-case specificresearch to support whether a person would be likely to gaze in the direction or area of a hazard prior to afall event. The recent developments of mobile eye tracking systems may allow for direct, on-siteevaluations, to assess probability of detection of claimed hazardous conditions. Herein, an evaluation of amobile eye tracking system is provided based on the application to a forensic case study that involved atransition from one space to another through a door. The results of the initial study were further evaluatedin three other areas, with similar settings. The results of two studies demonstrate support for the hypothesisthat a person would not look down at the landing area when stepping. However, in achieving these results,we found both support for the utility of the device as well as certain limitations for future use.
