AfC could contribute to improve building design to better satisfy human emotional demands 9. Architecture is a field where AfC has been infrequently applied, despite its obvious potential the physical-environment has on a great impact, on a daily basis, on human emotional states in general 7, and on well-being in particular 8. It has been applied often in education, healthcare, marketing and entertainment 3, 4, 5, 6, but its potential is still under development. Thus, AfC has emerged as an important research topic. Stimulated by the fact that emotions are involved in many background processes 2 (such as perception, decision-making, creativity, memory, and social interaction), several studies have focused on searching for a reliable methodology to identify the emotional state of a subject by using machine learning algorithms. Proposed by Rosalind Picard in 1997, it is an interdisciplinary field based on psychology, computer science and biomedical engineering 1. Our findings validate the use of Immersive Virtual Environments to elicit and automatically recognize different emotional states from neural and cardiac dynamics this development could have novel applications in fields as diverse as Architecture, Health, Education and Videogames.Īffective Computing (AfC) has emerged as an important field of study in the development of systems that can automatically recognize, model and express emotions. The model’s accuracy was 75.00% along the arousal dimension and 71.21% along the valence dimension. A set of features was extracted from these signals using various state-of-the-art metrics that quantify brain and cardiovascular linear and nonlinear dynamics, which were input into a Support Vector Machine classifier to predict the subject’s arousal and valence perception. An experiment involving the recording of the electroencephalography (EEG) and electrocardiography (ECG) of sixty participants was carried out. Four alternative virtual rooms were designed to elicit four possible arousal-valence combinations, as described in each quadrant of the Circumplex Model of Affects. This study, on the other hand, aims to develop an emotion recognition system for affective states evoked through Immersive Virtual Environments. Up to the present, elicitation has been carried out with non-immersive stimuli. Affective Computing has emerged as an important field of study that aims to develop systems that can automatically recognize emotions.
