The user interface (UI), in the industrial design field of human–computer interaction, is the space where interactions between humans and machines occur. The goal of this interaction is to allow effective operation and control of the machine from the human end, whilst the machine simultaneously feeds back information that aids the operators’ decision-making process. Examples of this broad concept of user interfaces include the interactive aspects of computer operating systems, hand tools, heavy machinery operator controls, and process controls. The design considerations applicable when creating user interfaces are related to or involve such disciplines as ergonomics and psychology.

Generally, the goal of user interface design is to produce a user interface which makes it easy, efficient, and enjoyable (user-friendly) to operate a machine in the way which produces the desired result. This generally means that the operator needs to provide minimal input to achieve the desired output, and also that the machine minimizes undesired outputs to the human.

as the picture we can see UI is about product features ,how the website page is physically laid out , where things should go ,what’s colours to use ,responsible for the creative and visual pieces of the site. and UX is about user emotions,UX focuses on the interactive side of the website, how it behaves ,such as a box sliding out , and how people might interact with it ,such as where they will click first.UX handles the architecture of the content and the site map.
