The visuAAL project set out to address a key challenge in ageing societies: how to help older adults live independently and safely using advanced video-based technologies, while fully respecting their privacy and tackling ethical, legal, and social concerns. Although video-based Active and Assisted Living (AAL) technologies can provide valuable real-time support, their adoption has been limited by worries about privacy, trust, and data protection, as well as uncertainty over how to make these systems acceptable to people from different backgrounds.
This issue is highly significant for society because it concerns the dignity, independence, and safety of older adults—values central to inclusive communities. If not addressed, barriers to adopting these technologies could mean missed opportunities to improve quality of life for older people, ease the burden on caregivers, and make better use of healthcare resources. At the same time, it is vital that technological solutions do not compromise fundamental rights such as privacy and autonomy. By making video-based monitoring both effective and privacy-aware, visuAAL helps build trust in digital health innovations and ensures technological progress benefits everyone, including vulnerable groups.
The main goal of visuAAL was to bridge the gap between what users need and expect from video-based AAL technologies and what is technically and legally possible. To achieve this, the project united experts from computer science, engineering, healthcare, law, business, and social sciences, as well as older adults, caregivers, and policy makers, to collaboratively address the challenge. The specific objectives included analysing user acceptance across different cultures and backgrounds, examining ethical and legal issues, developing privacy-aware algorithms and systems, raising awareness among stakeholders, training a new generation of researchers, and strengthening collaboration between academia, industry, and public services
Over the course of the project, visuAAL made strong progress towards its goals. The team produced extensive research on user acceptance, ethical and legal frameworks, and technical solutions for privacy-aware monitoring. This included in-depth studies with older adults, caregivers, and healthcare professionals to better understand their concerns and preferences, as well as the development of innovative privacy-by-design technologies that adapt to different contexts and user needs. The project also created and shared valuable datasets, published widely in scientific journals, and actively engaged with stakeholders through conferences, workshops, and public events.
A key achievement of the visuAAL project has been the comprehensive training of a cohort of highly skilled early-stage researchers, now well equipped to drive further innovation in privacy-aware video-based technologies for AAL. Through a strong programme of interdisciplinary research, specialist courses, secondments, and transferable skills training, these researchers gained expertise in technical, ethical, legal, and user-centred aspects of AAL solutions.
