The touch screen is a kind of human-machine interface, but there is a difference. Human-Computer Interface (HCI, also known as user interface or user interface): It is a medium for communicating and exchanging information between people and computers, and a dialogue interface, which is an important part of the computer system. It transforms between the internal form of information and the form that humans can accept. There are human-machine interfaces in all fields of human-computer information exchange. A medium for interaction and information exchange between the system and the user, which enables the conversion between the internal form of information and the acceptable form of human beings. There are human-machine interfaces in all fields of human-computer information exchange. For example, in a factory, we collect information on the temperature, humidity, and state of the machine in the factory, and monitor and record these parameters through a master controller, and in some unexpected situations. Can be dealt with when it is. This is a very typical human interface. In general, HMI (Human Machine Interface) systems must have several basic capabilities: Real-time data trend display - display the captured data immediately on the screen. Automatically record data - automatically save the data to a database for later viewing. Historical data trend display - visualize the data in the database. Report generation and printing - can convert the data into a report format and print it out. Graphical Interface Control - Operators can directly control devices such as the machine through a graphical interface. Alarm generation and recording - the user can define the conditions under which some alarms are generated, For example, if the temperature is excessive or the pressure exceeds the critical value, the system will generate an alarm under such conditions to notify the operator. HCI (Human-ComputerInteracTIon, short HCI): is the study of design, evaluation and implementation of interactive computing for people to use the system as well as scientific research on these phenomena. Human-computer interaction and human-machine interface are two closely related and different concepts. In the human-machine interaction process (HumanMachineInteracTIon), there is a layer, which we call the interface. From the psychological point of view, the interface can be divided into two levels: feeling (visual, tactile, auditory, etc.) and emotion. User interface design is an important part of the screen product. Interface design is a complex project involving different disciplines. Cognitive psychology, design, and linguistics all play important roles here. The three principles of user interface design are: setting the interface under the control of the user; reducing the memory burden of the user; maintaining the consistency of the interface.
