Study on the location of building evacuation indicators based on eye tracking

Evacuation indicator is an important factor affecting evacuation efficiency during emergency evacuation. In order to study the relationship between the distribution of human's points of regard and evacuation indicators during building evacuation, this paper carried out two groups of building emergency evacuation experiments, to get the data of human's points of regard, one of the experimenters was selected to put on eye tracker during the experiment. This paper presents a method to preprocess the data of eye tracker and further analyzes the pretreatment results. The results show that evacuation indicators in different areas are suitable for different placement, which based on the position distribution of human's points of regard. For example, evacuation indicators in the corridor are suitable for higher placement, and evacuation indicators in the staircase are suitable for lower placement.
