Method, device and pressure sensor cushions for detecting an incorrect sitting posture

摘要

Method for detecting a person's incorrect posture when working at a workstation. The pressure between at least part of the person's arm and a support arranged at the workstation for supporting the part of the arm therefore is measured. A signal is emitted if the measured pressure is outside a predetermined pressure range. For calibration an upper value is added to and a lower value subtracted from the pressure measured when the correct posture has been assumed, in order to obtain and to store an upper pressure limit and, respectively, lower pressure limit for the pressure range.
