Interaction research focuses on understanding the ways in which individuals and systems interact with each other. This can include studying interpersonal communication, human-computer interaction, and user experience design. Researchers in this field often employ a variety of methods, such as observation, surveys, and experiments, to better understand the dynamics of these interactions and how they can be improved. The ultimate goal of interaction research is to enhance communication, collaboration, and productivity in various contexts, ranging from everyday social interactions to complex technological systems.
