Title Accuracy-Coverage Tradeoff of Nocturnal Vital Sign Estimation in Smart Beds
Abstract We introduce a novel evaluation approach for smart bed systems that continuously measure vital signs. In particular, we demonstrate that estimation accuracy (or error) and measurement coverage time are key performance metrics, describing a performance tradeoff in practical smart bed systems. Based on a typical smart bed system that uses a force sensor array placed between bed mattress and frame, we evaluate the effect of different signal filtering options to illustrate viable design choices using our accuracy-coverage tradeoff analysis. In a full night recording study with six participants focusing on respiration rate estimation, we show that measurement coverage is an essential metric that should be analysed together with accuracy, when assessing the performance of smart bed systems.
