This document discusses affective computing in artificial intelligence. It defines affective computing as the study and development of systems that can recognize, interpret, process, and simulate human emotion and respond appropriately. The document outlines the architecture of intelligent systems that incorporate affective computing and describes how emotions can be perceived, particularly through facial expressions. Several algorithms used for emotion classification are mentioned. Applications of affective computing discussed include e-learning, marketing, employee monitoring, robotics, healthcare, and vehicle driving. Examples of artificial intelligence incorporating affective computing like Jibo, Pepper robot, and Amazon Alexa are provided.
