摘　　要：目的对比不同认知负荷下,电动车的不同多通道导航方式(听觉、触觉、视听、听触、视触)的表现差异是否存在变化。方法进行两轮电动车的模拟驾驶研究,采用组内设计,对比不同负荷下,五种导航方式的导航有效性及主观体验的优劣顺序是否存在变化。测量被试的失误次数、积极情绪及消极情绪进行统计分析。结果在不同负荷条件下,不同通道的导航系统失误次数、积极情绪和消极情绪的优劣顺序均发生变化。听觉通道及听觉参与的多通道具有较好的有效性,触觉通道的有效性表现较差,但触觉及相关多通道提供了较好的主观体验。在不同认知负荷下,适用的导航方式也有所不同。但也有部分通道在低负荷及高负荷下均有较好的表现。结论视听多通道导航适用于低负荷条件,而听触多通道导航在低负荷及高负荷条件下均可使用。Objective A electric cycle driving study based on stimulated context was conducted to compare whether there is a change in the order of navigational effectiveness and subjective experience of the five modalities types under different cognitive load conditions.Methods Errors,positive emotions and negative emotions were measured.The order of errors,positive and negative emotions changed under different load conditions.Results The auditory modality and the multimodal containing auditory had better effectiveness,while the vibrotactile modality showed poor effectiveness.However,the vibrotactile and related multimodal provided a better subjective experience.Conclusion Auditory-visual navigation is ideal for low-load conditions,while auditory-vibrotactile navigation can be used in low-load and high-load conditions.
