| 目的 探究感知体验中认知负荷对用户行为的影响，实现高效完成用户使用行为的目标任务。在体验过程中缩短心理维度的交互距离，打造深层次的感官及情感体验。方法 从感知体验视角针对用户的认知负荷行为进行深度剖析，在认知负荷视角下构建基于用户情绪的感知体验服务模型，借助PAD情感空间距离及欧式距离算法获取用户情感状态,利用服务设计方法对标认知负荷触点，进而调节用户认知识别路径。通过识别用户情绪、提取消极情绪触点并改善对应认知结构、优化信息呈现方式等减轻用户情感认知负担、提高用户认知效度。融合心理学、认知科学与设计学等多学科知识，探寻用户心理，聚焦用户使用需求及情感体验。结论 形成对产品“感知识别-认知-感知体验-情绪评价”全流程的一致性通感定义，重塑用户体验中的认知行为路径，减少交互过程中冗杂的感知及情感负荷，并通过汗糖检测APP的设计案例验证了方法的有效性和可行性。 |

| This paper is to explore the impact of cognitive load on user behavior in perceptual experience, and to achieve the target task of efficiently completing user’s usage behavior. In the experience process, the interaction distance of the psychological dimension is shortened to create a deep-level sensory and emotional experience. From the perspective of perceptual experience, we deeply analyze user’s cognitive load behavior, construct a service model of perceptual experience based on user’s emotion from the perspective of cognitive load, obtain user’s emotional state with the help of PAD emotional spatial distance and Euclidean distance algorithms, and use service design methods to benchmark cognitive load contacts, and then adjust the user’s cognitive recognition path. By identifying user emotions, extracting negative emotion contacts, improving corresponding cognitive structure, and optimizing information presentation methods, it reduces the user’s emotional cognitive burden and improves user’s cognitive validity. Integrate multidisciplinary knowledge such as psychology, cognitive science and design to explore user psychology and focus on user needs and emotional experience. Form a consistent synaesthetic definition of the whole process of “perception recognition-cognition-perceptual experience-emotional evaluation”, reshape the cognitive behavior path in user experience, reduce the complicated perception and emotional load in the interaction process, and the effectiveness and feasibility of the method is verified by the design case of the sweat sugar detection APP. |
