家族健康史（FHx）对于遗传疾病的早期诊断至关重要，可以通过几种方式收集，包括电子FHx工具，通过与其他信息管理门户网站链接，有助于轻松编辑和共享。用户对此类系统的接受度至关重要，特别是在有运动和认知问题的老年人中。这项研究调查了两种类型的FHx接口，标准和虚拟会话代理（VCA），使用了30名年轻人（18至30岁）和24名老年人（60岁以上）。收集了工作负载、可用性和性能数据。即使参与者需要更少的时间来完成标准界面上的五个任务中的三个，VCA界面在主观工作量和可用性方面表现得更好。此外，67%的老年人更喜欢VCA界面，因为它在数据收集过程中提供了基于上下文的指导。本研究的结果对虚拟助手在FHx和其他数据收集领域的使用具有启示意义。
Critical for the early diagnosis of genetic disorders, a Family Health History (FHx) can be collected in several ways including electronic FHx tools, which aid easy editing and sharing by linking with other information management portals. The user acceptance of such systems is critical, especially among older adults experiencing motor and cognitive issues. This study investigated two types of FHx interfaces, standard and Virtual Conversational Agent (VCA), using 30 young (between 18 and 30) and 24 older participants (over 60). Workload, usability and performance data were collected. Even though participants required less time to complete three of five tasks on the standard interface, the VCA interface performed better in terms of subjective workload and usability. Additionally, 67% of the older adults preferred the VCA interface since it provided context-based guidance during the data collection process. The results from this study have implications for the use of virtual assistants in FHx and other areas of data collection.
