The present invention relates to a
system comprising a first non-
contact sensor configured to generate first sensor data, and one or more processors configured to receive the first sensor data, isolate, using a classification
system, periods of the first sensor data in which respiratory-related movement is predominant from periods of the first sensor data in which bodily movement is predominant based on a frequency value derived from the first sensor data, obtain, using the classification
system, respiratory data from the periods of the first sensor data in which respiratory-related movement is predominant, obtain, using the classification system,
objective data from the respiratory data and the periods of the first sensor data in which bodily movement is predominant, calculate a
quality of life index based on the
objective data, and generate feedback based on the calculated
quality of life index.
