Maintaining or initiating regular physical activity (PA) is important for successful aging. Technology-based systems may support and stimulate older adults to initiate and persevere in performing PA. The aim of the current study was to assess to which extent a customised Kinect system is 1) a credible tool to increase PA in older adults, 2) motivating to perform PA by older adults, and 3) easy to be used in older adults.
A mixed-method cross-sectional feasibility study was performed in 5 aged care facilities in Flanders, Belgium. Aged participants were asked to perform a 20-30 min test with the intelligent Activity-based Client-centred Training (i-ACT) system. After the test, the 'Credibility and Expectancy Questionnaire' (CEQ), the 'Intrinsic Motivation Inventory'(IMI), the System Usability Scale (SUS), and semi-structured interviews were conducted in the older adults. Feedback was gathered using the thinking aloud method in both aged participants and healthcare professionals.
A total of 48 older adults (20 males and 28 females, mean age = 81.19 (SD = 8.10)), were included. The scores pertaining to system credibility and expectancy, system usability, and motivation towards use were moderate to good. Participants reported that they liked using the i-ACT system, but that the context could be more attractive by adding more visualisations. Twelve professionals stated that they observed involvement in older adults but think that i-ACT is better used in day care centres.
This study indicates that i-ACT is a usable and motivational system to engage older adults to perform PA and therefore supports successful aging. Future research is necessary to investigate the efficacy of i-ACT to perform PA and the transfer to regain and/or maintain engagement in ADLs that older adults find meaningful and purposeful at an older age. Also, further development of i-ACT is advisable to adapt the i-ACT system towards implementation at the home of older adults.

保持或开始有规律的身体活动（PA）对成功老龄化很重要。基于技术的系统可以支持和激励老年人开始并坚持进行 PA。本研究的目的是评估定制的 Kinect 系统在多大程度上 1）是增加老年人 PA 的可信工具，2）激励老年人进行 PA，3）易于老年人使用。
在比利时佛兰德斯的 5 家养老院进行了一项混合方法的横断面可行性研究。要求老年参与者使用智能基于活动的以客户为中心的培训（i-ACT）系统进行 20-30 分钟的测试。测试后，对老年人进行“可信度和期望问卷”（CEQ）、“内在动机量表”（IMI）、“系统可用性量表”（SUS）和半结构化访谈。在老年参与者和医疗保健专业人员中使用出声思考法收集反馈。
共有 48 名老年人（20 名男性和 28 名女性，平均年龄 81.19（SD=8.10）），得分与系统可信度和期望、系统可用性以及使用动机相关的分数为中等至良好。参与者报告说他们喜欢使用 i-ACT 系统，但认为通过添加更多的可视化效果，环境会更有吸引力。12 名专业人员表示，他们观察到老年人参与度有所提高，但认为 i-ACT 更适用于日托中心。
本研究表明，i-ACT 是一种可使用且具有激励性的系统，可以吸引老年人进行 PA，从而支持成功老龄化。需要进一步研究 i-ACT 进行 PA 的效果，以及将其转移到老年人身上，以恢复和/或保持他们认为有意义和有目的的日常生活活动的参与度。此外，建议进一步开发 i-ACT，以适应在老年人家庭中实施 i-ACT 系统。
