• The global demographic shift towards an aging population necessitates innovative approaches to care. Active and Assisted Living (AAL) technologies have emerged as crucial tools in empowering older adults to maintain independence and enhance their quality of life. Leveraging advancements in computer vision, AAL solutions, particularly video monitoring systems (VMS), offer exceptional capabilities in health monitoring, emergency detection, and remote caregiving support. Despite their efficacy, the widespread adoption of camera-based AAL technologies is impeded by significant concerns regarding privacy. This thesis aims to examine the acceptance of video-based AAL technologies by their potential users, with a specific emphasis on privacy. Among diverse user demographics, we focus on older adults and their caregivers, technologists, and other stakeholders involved in the process of care provision. The research aims to delineate the benefits, such as enhanced safety, and the associated barriers, including privacy threats related to video-based AAL technologies. Moreover, the thesis explores the development of privacy-preserving mechanisms, such as privacy filters, to address privacy concerns while ensuring user satisfaction and system efficacy. Based on these aims, the thesis employs a predominantly qualitative research approach grounded in user-centric design principles. This investigation contributes to a thorough understanding of the intersection between AAL technologies, user acceptance, and privacy preservation, thereby facilitating the development of ethically sound and technologically robust solutions to cater to the evolving needs of aging populations.
