The well-being of people with dementia (PWD) living in long-term care facilities is hindered due to disengagement and social isolation. Animal-like social robots are increasingly used in dementia care as they can provide companionship and engage PWD in meaningful activities. While most previous human-robot interaction (HRI) research studied engagement independent from the context, recent findings indicate that the context of HRI sessions has an impact on user engagement. This study aims to explore the effects of contextual interactions between PWD and a social robot embedded in the augmented responsive environment. Three experimental conditions were compared: reactive context-enhanced robot interaction; dynamic context-enhanced interaction with a static robot; a control condition with only the dynamic context presented. Effectiveness evaluations were performed with 16 participants using four observational rating scales on observed engagement, affective states, and apathy related behaviors. Findings suggested that the higher level of interactivity of a social robot and the interactive contextualized feedback helped capture and maintain users' attention during engagement; however, it did not significantly improve their positive affective states. Additionally, the presence of either a static or a proactive robot reduced apathy-related behaviors by facilitating purposeful activities, thus, motivating behavioral engagement.
居住在长期护理机构中的痴呆症患者（PWD）的幸福感受到了阻碍，因为他们存在脱离社会和社交孤立的问题。类似动物的社交机器人在痴呆症护理中越来越多地被使用，因为它们可以提供陪伴，并使 PWD 参与有意义的活动。虽然之前的大多数人机交互（HRI）研究都独立于情境研究参与度，但最近的研究结果表明，HRI 会话的情境对用户参与度有影响。本研究旨在探索 PWD 与嵌入增强响应环境中的社交机器人之间的情境交互的影响。比较了三种实验条件：具有反应性增强的机器人交互；具有静态机器人的动态增强的交互；仅呈现动态情境的对照条件。使用四个观察评分量表对 16 名参与者进行了有效性评估，观察到的参与度、情感状态和与冷漠相关的行为。研究结果表明，社交机器人更高水平的交互性和互动情境化反馈有助于在参与过程中捕捉和保持用户的注意力；然而，它并没有显著改善他们的积极情感状态。此外，无论是静态机器人还是主动机器人的存在都通过促进有目的的活动减少了与冷漠相关的行为，从而激发了行为参与度。
