A system for monitoring a lifestyle of a person in a living space(20) is disclosed. The system comprises sensors (8,9.10, 11, 18) to be located in the living space (20) for detecting a presence of the person and/or an activity of the person. The system further comprises a processor controlled system, comprising: means, coupled to the sensors (8,9, 10.11,18), for deriving events (E1,...., E10) caused by the person and times when the corresponding events occur, means for detecting event free periods of first lengths (L1) in which no events of a predetermined group occur (E1,...., E8), and means for deriving, an estimate of the in-bed time on the basis of the event free period of at least the first length detected in a first observation period (OP1) beginning before an usual in-bed time, whereby the estimate of the in-bed time is indicative for the actual time that the person has gone to bed, and whereby the usual in-bed time is representative for a time that the person usually goes to bed. The system is further arranged to determine an estimate of the out-bed time on the basis of the events (E1,....,E8), and event free periods of at least a second length (L2), detected in a second observation period (OP2) ending after an usual out-bed time. The estimate of the out-bed time is indicative for the actual time that the person has come out bed. The usual out-bed time is representative for a time that the person usually comes out bed. |
