摘要
为提升老年用户健康信息系统检索体验,通过分析信息表征(文本、音频、图像)与任务情境(简单、复杂)对老年用户检索绩效、认知负荷以及满意度的影响,探究健康信息系统信息表征的适老化设计,提出不同任务情境下适合老年用户的信息表征设计。采用双因素重复测量实验设计,邀请老年用户按照拉丁方顺序在文本、音频、图像引导下完成简单和复杂健康信息检索任务。总体上,图像表征引导老年用户初次使用健康系统检索绩效最优,认知负荷最低;但老年用户主观最喜爱音频表征。在简单任务中,音频表征设计适合老年用户;在复杂任务中,图像表征设计适宜老年用户;适老化改造应适当减少纯文本信息表征引导。
In order to improve the health information system retrieval experience of elderly users,the age-appropriate design of health system information representations was investigated by analyzing the effects of information representations(text,audio,and image)and task contexts(simple and complex)on retrieval performance,cognitive load,and satisfaction of elderly users,and a suitable information representation design for elderly users in different task contexts was proposed.A two-factor repeated measurement experimental design was used to invite elderly users to complete simple and complex health information search tasks,guided by text,audio and images in a Latin order.Overall,the image representation could guide elderly users to obtain the best health system retrieval performance for thefirst time with the lowest cognitive load,but elderly users subjectively preferred the audio representation the most.In simple tasks,audio representation design was appropriate for elderly users,while image representation design was appropriate in complex tasks.Elderly-oriented modifications should appropriately reduce text-only information representation guidanceg.
