摘要:
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.
