Human-robot interaction (HRI) refers to the ways in which humans and robots communicate and work together. This field studies how people perceive, understand, and respond to robots, focusing on improving collaboration and efficiency. HRI can be found in various settings, including homes, workplaces, and healthcare, where robots assist with tasks or provide companionship. Researchers in HRI explore factors like robot design, behavior, and social cues to enhance user experience. Effective HRI can lead to better outcomes in areas such as robotic surgery, autonomous vehicles, and service robots, making technology more accessible and beneficial for everyday life.
