Bigger-Is-Better Rule (BIBR)
Opis:
Previously, Krapohl (2020) evaluated the Bigger-Is-Better Rule (BIBR) on the polygraph electrodermal channel to assess whether there was a best minimum ratio between response sizes for assigning a score. Performance peaked at a minimum ratio between 10% and 20%. The ratios had been calculated by comparing the electrodermal responses for each relevant question against those of the immediately preceding comparison question. The analysis did not consider whether the same optimal ratio would be found if the relevant question electrodermal responses are compared to those of the stronger of two adjacent comparison questions. To investigate we analyzed responses from an independent sample of 255 laboratory cases. The data from those cases found the highest correlation between scores and ground truth occurred when the minimum difference between two electrodermal responses was 30%.

Opis:
In this article, we present a comprehensive measurement system to determine the level of user emotional arousal by the analysis of electrodermal activity (EDA). A number of EDA measurements were collected, while emotions were elicited using specially selected movie sequences. Data collected from 16 participants of the experiment, in conjunction with those from personal questionnaires, were used to determine a large number of 20 features of the EDA, to assess the emotional state of a user. Feature selection was performed using signal processing and analysis methods, while considering user declarations. The suitability of the designed system for detecting the level of emotional arousal was fully confirmed, throughout the number of experiments. The average classification accuracy for two classes of the least and the most stimulating movies varies within the range of 61‒72%.

Opis:
The paper presents the idea behind the implementation of a system designed to monitor biomedical parameters and the subject's behaviour on the basis of the architecture of measurement modules located on the body. The system was developed as a result of market launch of new generations of electronic devices combining high functionality, small size and low power consumption. The paper presents the elements of the system called BioSip, along with hardware solutions selected for the objectives to be accomplished, i.e. providing communication between system elements that would be efficient and resistant to artefacts, extending the time of operation for battery power supply, as well as ensuring a satisfactory level of reliability and ease of use.
