By mistake or ignorance, new designers and people distant from design, confuse the concepts of UX and UI-design. Although these terms are related, the differences are significant.

Imagine that you’ve bought a TV. It has a remote control that consists of buttons, a plastic body, and chips. If it were an application or a site, the UX-designer would be responsible for all the “stuffing”. And the UI designer would be responsible for the design of the buttons and the body.

UX/UI design is the work on the interface of an application or website, so that the user was intuitive and visually pleasant to interact with it.

UX (user experience) – “user experience.” UX is how the user interacts with the interface. A UX designer is responsible for the usability of a website or app.

UI (user interface) – “user interface”. UI is what the interface and its elements look like. The UI designer is responsible for the clarity of the site or application: the appearance of menus, buttons, readability of fonts, etc.

Users want the site or application to solve problems quickly, look nice, be understandable and work smoothly. Therefore, a good UX/UI design has certain requirements:

• clarity – no ambiguity, all parts of the product solve the user’s tasks or guide them,
• brevity – no unnecessary elements,
• recognizability of elements – for example, a check mark for confirmation will be green, and a cross for cancelation – red,
• Responsiveness – fast response of the interface to the user’s actions,
• consistency – elements should behave identically on every product page,
• aesthetics – the interface should be attractive and not distract from the task,
• efficiency – the user will make a minimum of actions before they get to the desired section,
• care – polite messages in case of errors or failures increase user loyalty.
