Abstract: The present invention relates to distinguishing different sedentary states of a subject. A sedentary state can refer to standing, sitting and/or lying. An apparatus for determining a sedentary state of a subject is presented that comprises a sensor interface for obtaining a movement signal indicative of a movement of the subject; an extraction unit for extracting a signal feature indicative of postural control oscillations of the subject from the movement signal, wherein the signal feature indicative of postural control oscillations is indicative of center of mass motion oscillations for preventing the subject from falling; and a classifier for classifying a sedentary state of the subject based on the signal feature indicative of postural control oscillations of the subject. Further, a corresponding method, computer program and system are presented.

Abstract: Various embodiments relate to methods, devices, and systems for ascertaining a sedentary body posture of a subject including: determining if the subject is in a sedentary state when the subject is sedentary for a pre-determined time; receiving a heart rate signal for least one heart rate feature when the subject is in the sedentary state; deriving at least one heart rate feature value when the subject is in the sedentary state further including filtering an arousal value from the received heart rate signal, so as to reduce an influence of the arousal on the determination of the sedentary posture; and determining the sedentary body posture of the subject based on a comparison between the derived at least one heart rate feature value and a pre-determined range associated with the corresponding at least one heart rate feature, wherein for each sedentary body posture, a pre-determined range is stored.

Abstract: The present invention relates to device, system and method for counting the number of cycles of a periodic movement of a subject, e.g. for step counting of a person.
