13. UI – User Interface
User interface (UI) design is the process of making interfaces in software or computerized devices with a focus on looks or style
Designers aim to create designs users will find easy to use and pleasurable.
Typically refers to graphical user interfaces but also includes others, such as voice- controlled ones.
User interfaces are the access points where users interact with designs.

14. UI vs. UX Design Often confused with UX design,
UI design is more concerned with the surface and overall feel of a design, whereas the latter covers the entire spectrum of the user experience.
One analogy is to picture UX design as a vehicle with UI design as the driving console.
In GUIs, you should create pleasing aesthetics and animations that convey your organization’s values and maximize usability.
