%X Evacuation signage playsa vital role in building evacuation. In order to test the efficiency of evacuation signage, the traditional methods are video analysis and after-drill questionnaires and the human factors are rarely considered. This paper investigates  the  impact  of  surrounding  pedestrians  on  the  sign  guidance  efficiency  during  building  emergency  evacuation, replacing  the  traditional  ways  with eye  tracking  device  method.  More  than  500  participants wereinvolved  in  the  series  of experiments to testthe influence of surrounding people on detecting and following signages. It is found that a) the subjective ignorance and  objective  ignorance  of  signs  exist  obviously  and areaffected  by  surrounding  people  number;  b)  strangers  and acquaintances  have  similar  effect  on  the  sign  detection  probability  and  direction  choosing  probability  in  the  safe  and  quick evacuation experiments, contrary to general belief; c) One surrounding personhas an important influence on the sign guidance effect, especially on the following probability, while three surrounding peoplenot. Based on the results of the experiments, a new logic of wayfinding within rooms was put forward and simulated to compared with the original logic. It is shown that the average right direction choosing percentage decreases by30% after considering the effect of surrounding pedestrians, proving that the impact of surrounding pedestrians must be considered in evacuation modeling and evacuation route design.
