A system for monitoring the reaction of a user and for adjusting output content based on the user's reaction includes an output unit, a monitoring unit, a synchronization unit, an analysis unit and a control unit. The output unit presents content to the user. The monitoring unit monitors a user parameter during a period during which a first content is presented to the user in order to obtain monitoring data from the user. The monitoring data is synchronized during the period with the first content so as to link in time the monitoring data and the first content. The analysis unit analyzes the monitoring data and links it to the first content in order to determine the user's reaction to the first content. The control unit controls the output unit to present a second content to the user that is selected based on the user's reaction to the first content.

The disclosure relates to an electronic device for measuring a bio-signal and a method for operation in the electronic device. The method includes obtaining a first impedance value, based on a first group of electrodes of the electronic device being in contact with a first portion of a human body, and a first region of a second portion of the human body being in contact with two electrodes among a second group of electrodes included in the electrode module according to a first measurement posture of a user, obtaining a second impedance value, obtaining a correction value and storing the correction value in a memory, and obtaining a corrected first impedance value by applying the correction value to the first impedance value.

Systems and methods for identifying and removing artifacts from electrodermal activity (EDA) data are described herein. A method includes identifying artifacts in segments of EDA data using unsupervised machine learning based on feature vectors extracted from segments of the data. After the artifacts are identified, they can be removed from the EDA data. Artifact-free EDA data can be used to estimate a patient's nociceptive state, which in turn can be used to modify a dosage of anesthetic drugs administered to the patient based on this estimation.
