Abstract:Human error is the main contributing factor to accidents in the workplace, especially among construction workers. This study adopted systematic literature review methods to discuss current research on using eye-tracking technology to improve construction safety, as well as present the challenges and opportunities. Experiments were conducted with 60 participants, who were asked to recognize the potential hazard in three construction pictures before and after a 10-minute training. Then, workers’ hazard identification rate (HIR) was defined. The MultiMatch method, a vector-based, multi-dimensional approach to compute scan path similarity, was adopted to calculate the similarity of scan path in five dimensions, vector, length, position, duration, and direction. Statistical methods, including T-test and one-way-ANOVA analysis, were performed to evaluate the effectiveness of the brief training.
