'Get that Camera Out of My House!' Conjoint Measurement of Preferences for Video-Based Healthcare Monitoring Systems in Private and Public Places

摘要

Facing the healthcare challenges of an aging society, the expansion of AAL system implementation in private and public environments is a promising way to improve healthcare in future smart homes and cities. The present study evaluated preferences for different video-based medical monitoring scenarios, which comprised the attributes medical safety (improved detection of medical emergencies), privacy (handling of video information), type and location of camera in a conjoint analysis. Medical safety was identified as key driver for preferences. Acceptance for video-based medical monitoring systems in public places was comparably high, given that privacy was protected. In contrast, acceptance for video-based monitoring in smart home environments was rather low due to privacy concerns. Based on the findings, recommendation for AAL system design and implementation were derived.
