Framework for the Classification of Emotions in People With Visual Disabilities Through Brain Signals

Abstract

Nowadays, the recognition of emotions in people with sensory disabilities still represents a challenge due to the difficulty of generalizing and modeling the set of brain signals. In recent years, the technology that has been used to study a person’s behavior and emotions based on brain signals is the brain–computer interface (BCI). Although previous works have already proposed the classification of emotions in people with sensory disabilities using machine learning techniques, a model of recognition of emotions in people with visual disabilities has not yet been evaluated. Consequently, in this work, the authors present a twofold framework focused on people with visual disabilities. Firstly, auditory stimuli have been used, and a component of acquisition and extraction of brain signals has been defined. Secondly, analysis techniques for the modeling of emotions have been developed, and machine learning models for the classification of emotions have been defined. Based on the results, the algorithm with the best performance in the validation is random forest (RF), with an accuracy of 85 and 88% in the classification for negative and positive emotions, respectively. According to the results, the framework is able to classify positive and negative emotions, but the experimentation performed also shows that the framework performance depends on the number of features in the dataset and the quality of the Electroencephalogram (EEG) signals is a determining factor.

Emotional Development and Regulation in Children: A Review of Recent Advances

“…Furthermore, the literature highlights the impact of emotional dysregulation on specific populations, such as individuals with borderline personality disorder, and the potential role of neuroplasticity in understanding and addressing these challenges (Thornton et al, 2023). Additionally, the emotional challenges encountered by individuals with sensory disabilities and the development of computational models for emotion recognition have been explored, reflecting the diverse applications of emotional research (López-Hernández et al, 2021).…”

“…motional development and regulation in children are critical components of their overall well-being and social adjustment. Understanding the intricate relationship between emotional competence and social development is essential for promoting healthy socioemotional development in children (López-Hernández et al, 2021;Olff, 2014). Over the years, extensive research has been conducted to explore various aspects of emotional development, including emotion regulation, recognition, and expression, and their impact on children's social and psychological adjustment.…”
