Abstract

Emotion recognition has garnered significant attention as a burgeoning research domain, owing to its potential applications across diverse fields such ashuman-computer interaction, affective gaming, marketing, and human-robotinteraction.Accurately interpreting and appropriately responding to human emotions remains a critical challenge in the development of systems. This obstacle necessitates a thoroughunderstanding of emotions to enhance user experiences within suchsystems.This paper conducts a comprehensive review focusing on advancements in emotion recognition techniques, with an emphasis on leveraging a variety of sensors and computational methods. Our study findingshighlight the significantimprovement to emotion recognition accuracy when multiple measures and computational methods, rather than a single modality, is used.This article contributes to the fieldby thoroughly reviewing and comparingdiverse measures and computational methods for emotion recognition. The study highlights the pivotal role of employing multiple modalities and advanced machine learning algorithms to achieve superior accuracy and reliability in emotion recognition.Furthermore, this research identifies potential avenues for further investigation and development, such as integrating multimodal data and exploring novel features and fusion techniques. The insights offered in this study provide valuable guidance for researchers and practitioners in the field, facilitating the advancement of technologies that adeptly understand and respond to human emotions.
