PERSONALITY DETERMINATION USING VIBRATING MOVEMENT PARAMETERS

Abstract

The human body responds to stimuli by organizing a response depending on purpose. How each person responds to external stress is determined by psychophysical reactions to these factors. But one key aspect that has not been studied enough so far, is the individual personality. This depends on a huge number of external factors (educational, cultural, social background characteristics, etc.), and also internal (genetic, anatomical, etc.). Practically every man has his personality and therefore it is impossible to classify in this respect. To study this issue, we used Likert scale, which quantifies the degree of discomfort due to external stress. Depending upon how the subject chooses a certain level of the 5 of the Likert scale, we determined the personality of the subject. Several individuals underwent the same type of vibrations. To measure the whole-body vibrations transmitted by the vibrating platform, we used the multiple acquisition vibrations system NetdB. We fixed PCB Piezotronics 356A16 triaxial accelerometers on the subjects. We processed the data with the dBFA Suite-Software acquisition control and post-processing data; we have maintained constant parameters to study how different subjects perceive the same external stimulus. We evaluated the perception’s magnitude with the Likert degree of discomfort scale: with values ranging from 1 (very little discomfort) to 5 (extreme discomfort) and we calculated, based on Rasch's model, the q coefficient, which indicates the type of personality for the studied subject.
