The Impact Of Landmarks On Path Integration Efficiency

Path integration refers to the process of updating its own location through its own motion information. Landmarks are of great significance to the location judgment and path finding. The influence of landmarks on path integration efficiency is of great reference value for guiding spatial memory cognition and map navigation. Previous studies have focused on the impact of landmarks and their own sports information on cruising, while the study of the impact of landmark characteristics on path integration efficiency has not yet been done.In this study, we used 3D-max technique and segmented maze to examine whether the combination of landmarks and the combination of different landmarks in the same layout outbound route would improve the response performance of the subjects in both experiments. In experiment 1,subjects were experimented under different visual environment (pure colour,texture,landmark,double clue) and channel type conditions(six meters just like,six meter mirror image,ten meters just like,ten meter mirror image ) and their response time, distance error, angle error and position error information were measured. The experimental results show that the combination of different visual environment and outbound path has a significant effect on the response time and the distance error in the return task. In experiment 2, the subjects were returned to the starting task under the combination of different color(red,blue) and shape(triangle,circle) landmarks and different channel types(six meters just like,six meter mirror image,ten meters just like,ten meter mirror image),and the response time,distance error, angle error and position error information were measured. The results of experiment 2 show that in the return task, the subjects have significant effect on the response time and distance error in the combination of color and shape of different landmarks.Based on the two experimental results, the following conclusions are obtained:First, in the same channel environment conditions, the visual environment for the double clue when the path of the integration score is higher than the landmark conditions and texture and solid color conditions; visual environment with landmarks will affect the reaction time, distance error Path integration efficiency indicators.Second, under the same visual environment, the shorter the path distance of a single channel, the better the path integration score of the subject; the channel distance estimation will also affect the path integration ability of the subject.Third, the visual environment and channel type in the path integration ability on the performance of significant interaction.Fourth, in the same channel environment conditions, subjects in the landmark combination of red circular path integration score is better than the landmark combination of red triangle, blue circle and blue triangle conditions; different landmark combination of the path of the subjects Integration efficiency is different.Fifth,In the same landmark conditions, the shorter the path distance of a single channel, the better the path integration results of the subjects. In the condition of the combination of landmarks with different shapes and colors, the longer the channel distance, the path of the subjects But worse.Six, the landmark combination and channel type in the path integration ability of the performance of the interaction significantly.
