This poster presents findings from a case study examining how a smart sensor system shaped everyday care in a Dutch nursing home. The study took place in a small-scale ward for 32 residents with psychogeriatric conditions. In each apartment, a ceiling-mounted sensor with a camera-based contour recognition function was installed. When certain movement patterns occur (e.g., getting out of bed, possible falls), the system sends alerts and a live video feed to staff phones, enabling them to assess situations at a distance and reduce unnecessary room checks, contributing to a calmer environment. Observations, interviews and a focus group were thematically analyzed into a narrative that provides an insight into an ordinary day on the ward, showing how the sensor influenced everyday care decisions. While the sensor was often valued by staff for providing oversight and helping to prioritize care, one resident expressed discomfort by saying: “I’m still independent; I just don’t want that camera turned on.” For a health care worker however, the sensor had come to feel like an ordinary part of the care environment: “It’s like a pink wall. The wall is pink, so the sensor is just part of the room.” These examples show that the sensor could be experienced as supportive, intrusive, and routine, depending on personal needs and values. Yet these differences were not always discussed together. Opportunities for shared decision-making about whether, when, and how the sensor should be used were limited. Staff also explained that the sensor requires a period of baseline learning to recognize individual movement patterns, and the current system makes it difficult to adjust settings per resident, which restricts the possibility of tailoring use to personal preferences. These findings highlight the need for clearer dialogue and organizational support to strengthen shared decision-making in the implementation of smart sensor systems.
