| Abstract: | In order to reduce the influence of interference objects around the emergency evacuation signs in university buildings on the effectiveness of sign identification,and find out the combination design with the lowest interference,four parameters of size,color,shape and position were introduced to design and form 18 interference situation.The eye movement technology was used to study the visual behavior of college students searching for emergency evacuation signs in different interference situation through the experiments.Four eye movement indexes,including Duration of Interval,Time to First Fixation-AOI,Duration of First Fixation-AOI and Total Duration of Glances were quantitatively studied by variance analysis and F-cluster analysis.The results showed that when only one factor was considered,the interference objects with three types of green,circle and larger had the lowest interference on emergency evacuation signs.Considering the three factors of color,shape and size at the same time,18 kinds of interference situation was clustered into four categories,and the interference objects with larger green rectangle,larger green triangle,identical green circle,larger green circle,larger red rectangle,larger red triangle and larger red circle were the design with the lowest interference.In addition,the design example of the interference objects in two situation at a place of Central South University was given. |
