D3.4. Advancing the use of visual systems to support older adults managing multiple chronic health conditions

This deliverable reports on research into how video-based camera systems can help older adults manage multiple chronic health conditions at home. It focuses on three main areas: how visual systems support self-management (ESR 7), how behaviour change strategies can improve acceptance (ESR 8), and how to address privacy and ethical concerns. The first part shows that camera systems can help older adults with tasks such as physical activity, medication, and rehabilitation, offering benefits especially when they are easy to use and deliver clear value. A scoping review using the Technology Acceptance Model (TAM) identified key factors affecting usability and usefulness. The second part applies behavioural science to understand why older adults often reject camera-based systems, highlighting psychological barriers such as low perceived need and fear of being watched. The concept of “future self-continuity” is introduced as a way to increase acceptance by helping users connect their current actions to future health benefits. Finally, the report reviews technical and behavioural strategies to reduce privacy concerns, such as using unobtrusive design or improving user control. The findings will guide future interventions and will be updated in a later report.
