Real vs. immersive-virtual emotional experience: Analysis of psycho-physiological patterns in a free exploration of an art museum.

ABSTRACT: Virtual reality is a powerful tool in human behaviour research. However, few studies compare its capacity to evoke the same emotional responses as in real scenarios. This study investigates psycho-physiological patterns evoked during the free exploration of an art museum and the museum virtualized through a 3D immersive virtual environment (IVE). An exploratory study involving 60 participants was performed, recording electroencephalographic and electrocardiographic signals using wearable devices. The real vs. virtual psychological comparison was performed using self-assessment emotional response tests, whereas the physiological comparison was performed through Support Vector Machine algorithms, endowed with an effective feature selection procedure for a set of state-of-the-art metrics quantifying cardiovascular and brain linear and nonlinear dynamics. We included an initial calibration phase, using standardized 2D and 360° emotional stimuli, to increase the accuracy of the model. The self-assessments of the physical and virtual museum support the use of IVEs in emotion research. The 2-class (high/low) system accuracy was 71.52% and 77.08% along the arousal and valence dimension, respectively, in the physical museum, and 75.00% and 71.08% in the virtual museum. The previously presented 360° stimuli contributed to increasing the accuracy in the virtual museum. Also, the real vs. virtual classifier accuracy was 95.27%, using only EEG mean phase coherency features, which demonstrates the high involvement of brain synchronization in emotional virtual reality processes. These findings provide an important contribution at a methodological level and to scientific knowledge, which will effectively guide future emotion elicitation and recognition systems using virtual reality.

Project description:BackgroundImmersive Virtual Reality (iVR) storytelling is a concept that merges ground-breaking virtual reality technology with the traditional art of storytelling. Virtual reality storytelling offers a rare opportunity to present abstract experiences that challenge boundaries, heighten emotions, and convey previously intangible concepts. Scientific research into immersive virtual reality storytelling is still in its infancy, particularly regarding the field of education in Nursing and Midwifery. Therefore, this study set out to investigate the subjective experience of using an immersive virtual reality storytelling experience as an active pedagogy.MethodsThis was an evaluative study incorporating a multimodal approach encompassing a cross-sectional survey and observational study conducted in a large University in Ireland, offering major undergraduate and graduate degree programmes in the fields of Nursing and Midwifery. Students were invited to view the innovative virtual reality storytelling experience "Wonderful You" (BHD Immersive) that tells the story of the first 9 months of a baby's life inside the woman's womb. On completion, students were asked to complete an anonymous survey about their experience. Observational studies were also carried out, examining the student's engagement and interaction with the iVR experience. A combination of statistical and thematic qualitative analysis was employed to interpret the respective summative rating scale and open-ended response questions in the evaluation survey. Data captured from the observations were grouped into categories and analysed capturing key themes.ResultsA response rate of 71.2% (n = 94) identified iVR storytelling as a memorable learning experience that triggered students' engagement and motivation to learn. IVR storytelling enabled students to visualise and better understand abstract concepts. Qualitative analysis of narrative responses revealed the positive evaluations of the iVR storytelling experience. Observational studies further revealed students were highly engaged and interacted positively with the iVR storytelling experience.ConclusionsThe full potential of this new medium of iVR storytelling has yet to be seen. However, this study provides an encouraging insight into the positive attributes of iVR storytelling that engages students and creates authentic active learning experiences.
