Virtual humans (VHs) are gaining increasing attention in various fields, including games and cultural heritage and technological contexts including virtual reality and augmented reality. Recently, since VHs can simulate human-like behavior, VHs have been proposed as virtual assistants (VAs) for all sorts of education and training applications, including applications focused on the improvement of quality of life (QoL) and well-being. In this research work, we consider the quality and efficiency of VHs implemented as part of the MyHealthWatcher project, which focuses on the monitoring of health-related parameters of elder users to improve their QoL and self-management of chronic conditions. To validate our hypothesis that the increased quality of the VH has a positive effect on user satisfaction and user quality of interaction with the system, we developed and integrated into the MyHealthWatcher system two VH variations. The first was developed with mainstream technologies and the second was developed using a professional pipeline. The two variations developed were assessed by representative target users through a between-subject focus group study. The development and validation process of the two variations allowed us to draw valuable conclusions, which are discussed in this paper.

老年用户虚拟人助理质量评估

虚拟人 (VH) 在各个领域越来越受到关注，包括游戏和文化遗产以及包括虚拟现实和增强现实在内的技术环境。最近，由于 VH 可以模拟类人行为，VH 已被提议作为各种教育和培训应用的虚拟助手 (VA)，包括专注于提高生活质量 (QoL) 和幸福感的应用。在这项研究工作中，我们考虑了作为 MyHealthWatcher 项目一部分实施的 VH 的质量和效率，该项目侧重于监测老年用户的健康相关参数，以改善他们的生活质量和慢性病的自我管理。为了验证我们的假设，即 VH 质量的提高对用户满意度和用户与系统交互的质量有积极影响，我们开发了两个 VH 变体并将其集成到 MyHealthWatcher 系统中。第一个是使用主流技术开发的，第二个是使用专业管道开发的。开发的两种变体由具有代表性的目标用户通过主题间焦点小组研究进行评估。这两种变体的开发和验证过程使我们能够得出有价值的结论，本文将对此进行讨论。
