摘要
为解决铁路旅客与自动售票机交互时由于认知负荷高而产生的操作不流畅、成功率不高等问题,引入认知负荷理论对自动售票机进行交互设计研究。文章介绍认知负荷理论,深入分析交互过程中认知负荷产生的原因。针对自动售票机交互设计现状,从信息结构设计、任务流程设计、引导性设计、精简功能4个角度出发,通过平衡好信息结构宽度和深度相互制约的关系,设计符合用户操作习惯的任务流程,添加符合认知规律的旅客操作导航,删除低优先级冗余功能,设计了一个操作直观简便的自动售票机交互方案。
In order to solve the problems of imperfect operation experience and low success rate during the interaction between railway passengers and Ticket Vending Machine （TVM）owing to high cognitive load, Cognitive Load Theory （CLT） was put forward for the interaction design of TVM. By introducing CLT, the source of cognitive load during interaction was summarized. According to the current situation of TVM interaction design, the interaction design contained four parts： information structure design, transaction flow design, guidance design and function simplification. Firstly, balance the mutually restricted relations between width and depth in information structure design; and then design transaction fow diagram which suited passenger’ s pattern of behavior; thirdly, add navigation bar adjusting to passengers’ cognition rule; fnally, delete redundant functions of low priority. An interaction design plan of TVM based on CLT was presented.
