Emotion recognition techniques using physiological signals and video games –Systematic review–

Emotion recognition systems from physiological signals are innovative techniques that allow studying the behavior and reaction of an individual when exposed to information that may evoke emotional reactions through multimedia tools, for example, video games. This type of approach is used to identify the behavior of an individual in different fields, such as medicine, education, psychology, etc., in order to assess the effect that the content has on the individual that is interacting with it. This article shows a systematic review of articles that report studies on emotion recognition with physiological signals and video games, between January 2010 and April 2016. We searched in eight databases, and found 15 articles that met the selection criteria. With this systematic review, we found that the use of video games as emotion stimulation tools has become an innovative field of study, due to their potential to involve stories and multimedia tools that can interact directly with the person in fields like rehabilitation. We detected clear examples where video games and physiological signal measurement became an important approach in rehabilitation processes, for example, in Posttraumatic Stress Disorder (PTSD) treatments

A Review on EEG Signals Based Emotion Recognition

Emotion recognition has become a very controversial issue in brain-computer interfaces (BCIs). Moreover, numerous studies have been conducted in order to recognize emotions. Also, there are several important definitions and theories about human emotions. In this paper we try to cover important topics related to the field of emotion recognition. We review several studies which are based on analyzing electroencephalogram (EEG) signals as a biological marker in emotion changes. Considering low cost, good time and spatial resolution, EEG has become very common and is widely used in most BCI applications and studies. First, we state some theories and basic definitions related to emotions. Then some important steps of an emotion recognition system like different kinds of biologic measurements (EEG, electrocardiogram [EEG], respiration rate, etc), offline vs online recognition methods, emotion stimulation types and common emotion models are described. Finally, the recent and most important studies are reviewed

Catching feelings: Measurement of Theatre Audience Emotional Response Through Performance

Attendance at live theatre is declining. Although emotional experiences are a primary motivator for people to attend theatre, many leave disappointed, never to return. Catching feelings, therefore, is core to successful theatre business models. Yet, there is a surprising lack of research investigating audiences’ emotional experiences while they are watching a play. This thesis explores the complex historical partnership between theatre and emotion, and suggests that measurement of physiological response using wearable biometric equipment is a viable tool for measuring audience emotional response during a performance. Literature on measuring emotion in theatre is reviewed and categorized into four core areas. A framework for measuring physiological responses to theatre performances is proposed. A mixed-methods experiment measuring the physiological responses of nine audience members attending a production of Lauren Gunderson’s play "I and You" at London's Hampstead Theatre is analysed and the playwright is interviewed on her expectations of the audiences’ emotional response. The findings indicate that participant physiological arousal significantly increased at the surprise climax of the play as compared to two other sections of the play. Participants reported feeling, similarly, emotions of surprise and sadness. This suggests that audience emotional responses correlate to plot points with expected emotional response. Additionally, the use of measurement equipment is well tolerated during a performance. Based on this, a new model for rating the impact and capacity needs of emotional engagement activities is suggested, providing a novel tool for theatre companies to influence the behaviour of new and returning attendees, generate additional revenue, and connect audiences and theatrical experiences in enhanced, emotionally meaningful ways
