人机交互与人机界面的关系：
The relationship between human-computer interaction and man-machine interface:
人机交互是指人与机器的交互，本质上是人与计算机的交互。或者从更广泛的角度理解：人机交互是指人与含有计算机的机器的交互。具体来说，人机交互用户与含有计算机机器之间的双向通信，以一定的符号和
Human computer interaction refers to the interaction between human and machine, in essence, the interaction between human and computer. Or from a broader perspective: human-machine interaction refers to the interaction between people and machines that contain computers. Specifically, two-way communication between users and computer machines is based on certain symbols.
液晶屏被用作人机界面显示器
The LCD screen is used as a man-machine interface display
动作来实现，如击键，移动鼠标，显示屏幕上的符号/图形等。这个过程包括几个子过程：识别交互对象-理解交互对象-把握对象情态-信息适应与反馈等；而人机界面是指用户与含有计算机的机器系统之间的通信媒体或手段，是人机双向信息交互的支持软件和硬件。这里界面定义为通信的媒体或手段，它的物化体现是有关的支持软件和硬件，如带有鼠标的图形显示终端等。
Actions are implemented, such as keystrokes, moving the mouse, displaying symbols / graphics on the screen, etc. The process includes several sub processes: identification of interactive objects - understanding interactive objects - grasping object modality - Information adaptation and feedback, and man-machine interface refers to the communication media or means between users and machine systems containing computers, and is the support software and hardware of human-machine two-way information interaction. The interface is defined as the media or means of communication. Its materialization is embodied in supporting software and hardware, such as graphical display terminals with mouse.
交互是人与机-环境作用关系/状况的一种描述。界面是人与机-环境发生交互关系的具体表达形式。交互是实现信息传达的情境刻画，而界面是实现交互的手段。在交互设计子系统中，交互是内容/灵魂，界面是形式/肉体；然而在大的产品设计系统中，交互和界面，都只是解决人机关系的一种手段，不是最终目的，其最终目的是解决和满足人的需求。
Interaction is a description of the relationship between people and machine environment. Interface is a specific form of interaction between human and machine environment. Interaction is the depiction of information conveyed, and the interface is the means to achieve interaction. In the interactive design subsystem, interaction is the content / soul, the interface is the form / body; however, in the large product design system, interaction and interface are only a means to solve the man-machine relationship, not the ultimate goal, and the ultimate aim is to solve and meet the needs of people.
交互设计是从属于产品系统的，是对成功的产品设计的一种强有力的支持与完善。
Interaction design is a powerful support and improvement from the product system to the successful product design.
如果利用系统论的观点，交互设计是从属于产品设计系统的子系统。
If we use the viewpoint of system theory, interaction design is subordinate to the subsystem of product design system.
