Human-Computer Interface (Human-Computer Interface, also known as user interface or user interface): It is the media and dialogue interface between people and computers to transfer and exchange information. It is an important part of the computer system. It realizes the transformation between the internal form of information and the human acceptable form. There is a human-machine interface in the fields of human-machine information exchange.
Human-Computer Interaction (HCI): It is the science that studies the design, evaluation, and implementation of interactive computing systems for people and the research on these phenomena.
Human-computer interaction and human-machine interface are two concepts that are closely related and not identical
In the human machine interaction process (HumanMachine Interaction), there is a level that we call the interface. Divided from the psychological meaning, the interface can be divided into two levels: sensory (visual, tactile, auditory, etc.) and emotional. User interface design is an important part of the screen product. Interface design is a complicated project with different subjects involved. Cognitive psychology, design science, linguistics, etc. all play an important role here.
The three major principles of user interface design are: setting the interface under the control of the user; reducing the user’s memory burden; and maintaining the consistency of the interface.
