The Effect Of Navigation Display Clutter,Spatial Memory Strategy On Performance Under Different Immersive Conditions

At present,the increasing number of cars has led to a surge in the number of automobile drivers,so GPS navigation is more widely used.Navigation display information and individual differences have an important impact on the driver’s navigation performance at key intersections.The purpose of this study is to explore the effect of navigation display clutter,spatial memory strategy on performance under different immersive conditions.A combination of performance,subjective and physiological measures is used to study the performance of the participants in the presentation-based driving experiment.The spatial memory task experiment was used to distinguish people with different spatial memory strategies.First experiment:2(immersion:high immersion 3D presentation,low immersion 2D presentation conditions)× 2(display clutter:high,low),with 30 individuals.The performance and preferences of navigation users in navigation display with different display clutter under different immersion conditions were discussed.Second Experiment;2(immersion:high immersion 3D presentation,low immersion 2D presentation conditions)× 2(spatial memory strategy:egocentric spatial memory,allocentric spatial memory),with 28 individuals.The performance and preferences of navigation users with different spatial memory strategies under different immersion conditions were discussed.The results show that:1)In terms of performance indicators,in experiment 1,it shows that the main effect of the immersion is significant,the RT of high display clutter is longer than the low display clutter.In Experiment 2,the interaction between immersion and spatial memory strategy was significant,and the performance of those who favored egocentric spatial memory strategies under high immersion conditions was significantly higher than that of allocentric spatial memory strategists;2)In terms of physiological measures,in experiment 1,the main effect of the display clutter was significant,and the emotional arousal and psychological load of low display clutter were significantly lower than the high display clutter.In experiment 2,the main effect of immersion was significant,and the emotional arousal and psychological load of low immersion were significantly higher than high immersion;3)In terms of subjective ratings,in experiment 1,the interaction effect between immersion and display clutter is significant,and people prefer higher display clutter under high immersion conditions.In Experiment 2,individuals with allocentric spatial memory strategies preferred low immersion,and individuals with allocentric spatial memory strategies preferred high immersion 3D presentation.The conclusions are:(1)The interface with low display clutter is more helpful for the extraction of navigation information.In general,the low display clutter can bring better navigation performance.(2)The navigation interface with low immersion and high clutter is not conducive to the extraction of navigation information.At the same time,the subjective preference is low.It is not recommended to use it too much in the daily navigation interface.(3)Under the condition of low display clutter,the egocentric spatial memory strategist is more suitable for a highly immersive navigation interface,which is consistent with the subjective preference of the s egocentric spatial memory strategist.This research combines the in-vehicle navigation interface design with human spatial cognitive factors to enrich the empirical research of navigation interfaces.Starting from multi-dimensional data,it can more objectively and comprehensively explain the research issues related to navigation presentation.Provide design ideas for the navigation interfaces of different space strategists,and design navigation that is more in line with user habits,or more suitable for realistic scenarios.
