What to study in human-computer interaction? The relevant content is as follows:
User Experience (UX): The study of the subjective feelings and emotional responses of users when using a product or system, including user satisfaction, ease of use, usability and other aspects of the experience.
User Interface Design: The design of the interface between the user and the computer system, including graphical user interface (GUI), command line interface, touch interface, virtual reality interface, etc., in order to provide a user-friendly operating environment.
Information Visualization: Research on how to present large-scale, complex information to the user through graphics, charts, etc., so that the user can better understand and analyze the information.
Interaction Techniques: Research on various interaction methods and techniques, including gesture recognition, voice recognition, touch screen, virtual reality, etc., as well as their application and optimization.
Cognitive Psychology and Human Factors: The study of human cognition, memory, learning, problem solving and other psychological processes, as well as human factors engineering, i.e., taking into account the characteristics and needs of human beings, and designing systems and interfaces that conform to human characteristics.
User surveys and user research: through surveys, observations, interviews, etc., to understand user needs, behaviors, and feedback, in order to guide the interface design and improvement.
Accessibility: Designing interfaces and interactions that make computer systems accessible to people with disabilities.
Importance and application areas of HCI:
