The use of video-based ambient assisted living (AAL) technologies represents an innovative approach to supporting older adults living as independently and autonomously as possible in their homes. These visual devices have the potential to increase security, perceived safety, and relief for families and caregivers by detecting, among others, emergencies or serious health situations. Despite these potentials and advantages, using video-based technologies for monitoring different activities in everyday life evokes concerns about privacy intrusion and data security. For a sustainable design and adoption of such technical innovations, a detailed analysis of future users' acceptance, including perceived benefits and barriers is required and possible effects and privacy needs of different activities being filmed should be taken into account.
Therefore, the present study investigated the acceptance and benefit-barrier-perception of using video-based AAL technologies for different activities of daily living based on a scenario-based online survey ( = 146).
In the first step, the results identified distinct evaluation patterns for 25 activities of daily living with very high (e.g., changing clothes, showering) and very low privacy needs (e.g., gardening, eating, and drinking). In a second step, three exemplary activity types were compared regarding acceptance, perceived benefits, and barriers. The acceptance and the perceived benefits of using video-based AAL technologies revealed to be higher in household and social activities compared to intimate activities. The strongest barrier perception was found for intimate activities and mainly regarded privacy concerns.
The results can be used to derive design and information recommendations for the conception, development, and communication of video-based AAL technologies in order to meet the requirements and needs of future users.
视频环境辅助生活（AAL）技术的使用代表了一种支持老年人尽可能独立和自主地在家中生活的创新方法。这些视觉设备有可能通过检测紧急情况或严重的健康状况等来增加安全性、感知安全性和减轻家庭和护理人员的负担。尽管存在这些潜力和优势，但使用基于视频的技术来监测日常生活中的不同活动会引发对隐私侵犯和数据安全的担忧。为了可持续设计和采用此类技术创新，需要详细分析未来用户的接受程度，包括感知到的益处和障碍，以及应考虑不同拍摄活动的可能影响和隐私需求。
因此，本研究基于基于情景的在线调查（n = 146），调查了使用基于视频的 AAL 技术进行不同日常生活活动的接受程度和益处-障碍感知。
在第一步中，结果确定了 25 种日常生活活动的不同评估模式，这些活动具有非常高的隐私需求（例如，换衣服、洗澡）和非常低的隐私需求（例如，园艺、饮食和饮水）。在第二步中，比较了三种典型的活动类型，涉及接受度、感知益处和障碍。与亲密活动相比，使用基于视频的 AAL 技术的接受度和感知益处更高，出现在家庭和社会活动中。最强烈的障碍感知是针对亲密活动的，主要涉及隐私问题。
研究结果可用于为基于视频的 AAL 技术的构思、开发和传播提供设计和信息建议，以满足未来用户的要求和需求。
