摘要
针对认知负荷影响应急地图用户读图效率的问题,该文分析了应急情境下增加用户认知负荷的压力源,探讨了应急地图认知中人类视觉信息的处理过程。在此基础上,提出顾及用户视觉信息处理的应急地图设计原则和方法,通过降低用户的认知负荷,提高应急情境下用户的读图效率。完成了消防应急救援路线图的设计,并利用Itti视觉注意模型对其进行评估。结果显示,该图能够快速吸引用户的视觉注意力,激发用户自下而上的信息加工过程,在高压力、高风险的应急情境下能够有效降低用户的认知负荷,有助于用户快速读图。
Aiming at emergency map reading inefficiency,the paper first analyzed stressors that increase users’cognitive load under emergency contexts,discussed the human visual information processing in users’map cognition.Then map design principles and methods were proposed to reduce the cognitive load.After that,a fire emergency rescue route map was presented and evaluated with Itti visual saliency detection model.The results showed that the map attracted users’attention quickly through stimulation of their bottom-up visual information processing.It could reduce the users’cognitive load effectively and help them read map quickly under high-stress and high-risk emergency contexts.
