Assessing functional decline related to activities of daily living (ADLs) is deemed significant for the early diagnosis dementia. As current assessment methods ADLs often lack ability capture subtle changes, technology-based approaches are perceived as advantageous. Specifically, digital biomarkers emerging, offering a promising avenue research, they allow unobtrusive and objective monitoring. A study was conducted with involvement 36 participants assigned three known groups (Healthy Controls, Subjective Cognitive Decline Mild Impairment). Participants visited CERTH-IT Smart Home, an environment that simulates fully residence, were asked follow protocol describing different ADL Tasks (namely Task 1 - Meal, 2 Beverage 3 Snack Preparation). By utilizing data from fixed in-home sensors installed in identification performed their derived features explored through developed CARL platform. Furthermore, differences between investigated. Finally, overall feasibility satisfaction evaluated. The composition attainable, differentiation among HC group compared SCD MCI considering feature "Activity Duration" Meal Preparation possible, while no difference could be noted groups. This ecologically valid determined feasible, expressing positive feedback. findings additionally reinforce interest need include people preclinical stages dementia research further evolve develop clinically relevant biomarkers.
