摘　　要：目的为提升老年群体居家场景下的慢病健康管理体验,聚焦认知老化现象,提升不同操作任务与认知需求的适配度,优化家庭健康管理终端产品交互设计。方法通过文献查阅归纳老年人在认知活动中感知觉、智力、情感等相关特征要素,完成认知老化特征向设计指标映射;与此同时,引入SRK认知理论及其决策图,对设计载体完成关键任务分层;进一步将上述设计指标与任务层级作为模型变量,通过问卷数据分析,构建结构方程模型并获取分析结果,明确不同任务层级下的设计指标权重。结论以家庭健康管理产品交互设计为例,通过结构方程模型分析,发现感官性体验对完成技能型任务具有显著正向影响、感官性体验和可用性体验对完成规则型任务具有显著正向影响、感官性体验和可用性体验及情感性体验均对知识型任务有显著正向影响,并获取每个体验维度中应重点关注的评价指标。实现从不同任务类型的角度分层次优化交互体验,为居家场景下的医疗健康管理产品适老化交互设计提供理论参考。The work aims to focus on the phenomenon of cognitive aging to improve the adaptability of different operation tasks and cognitive needs,and optimize the interaction design of home health management terminal products,in order to improve the chronic disease health management experience of the elderly in the home scene.First of all,through literature review,the sensory perception,intelligence,emotion and other relevant feature elements of the elderly in cognitive activities were summarized to complete the mapping of cognitive aging characteristics to design indicators.At the same time,SRK cognitive theory and decision diagram were introduced to complete the key task stratification of product.Further,the above design indicators and task levels were taken as model variables,and through the analysis of questionnaire data,the structural equation model was established and the data analysis results were obtained to clarify the weight of design indicators under different task levels.With the interaction design of home health management products as an example,through the structural equation model analysis,it is concluded that sensory experience has a significant positive impact on the skilled tasks,sensory experience and usability experience have a significant positive impact on the regular tasks and sensory experience,usability experience and emotional experience have a significant positive impact on knowledge tasks.The evaluation indicators that should be focused on in each dimension of experience are obtained.The hierarchical optimization of interactive experience from the perspective of different task types is realized,which provides theoretical reference for aging-appropriate interaction design of medical and health management products in the home scene.
