Human-Robot Interaction (HRI) refers to the study and design of how humans and robots communicate and work together. This field explores various aspects, including the ways robots can understand human behavior, respond to commands, and perform tasks alongside people. HRI aims to improve the effectiveness and safety of robotic systems in various environments, such as homes, workplaces, and healthcare settings. Researchers in HRI focus on developing user-friendly interfaces and social robots that can engage with humans naturally. By incorporating elements of artificial intelligence and machine learning, robots can learn from their interactions and adapt to individual preferences. This enhances collaboration and makes robots more useful in everyday life.
