Psycho-Physiological Response in 3D Multiple Object Tracking

Recently, advances in stereoscopic imaging technology have provided new opportunities to view three-dimensional (3D) images. 3D imaging technology will likely be further utilized in medical facilities. In our study, we measured oxygenated hemoglobin (oxyHb) and the high-frequency component (HF) as objective parameters and the Roken Arousal Scale (RAS) and the Simulator Sickness Questionnaire (SSQ) as subjective parameters in experimental participants during the Multiple Object Tracking (MOT) task in 3D stereoscopic image conditions. The highest mean value of oxyHb change was recorded for the 3D-MOT task. In the 3D condition, HF values were significantly different between MOT and no MOT. Subjective evaluation of the RAS and SSQ results showed that general activation increased and disorientation decreased when experimental participants performed 3D-MOT. In summary, we found that the psycho-physiological responses of test subjects were affected by presentation conditions, and 3D-MOT decreased problems with 3D comprehension and led to brain activation.
