A user interface, or UI, is the interface point or space where machines and humans interact or communicate through displays that control operation according to human demands. There are different forms of user interfaces, each evolving from the batch and command-line interface. With the advent of computers and computing software, user interfaces have transformed in use and popularity which has led to the creation of entirely new employment opportunities in user interface design. Today, we use user interfaces in virtually every gadget from computer equipment, mobile phones, and web applications to even learning materials and printers. The sole purpose of a user interface is to ensure effective communication between humans and machines.

What is UI/UX?

UX means user experience, and is the design process teams use to create products that provide meaningful experiences to its users. UI stands for user interface and acts as the point of human-computer interaction and communication in a device. It is the way a user interacts with an application or website. UI and UX are often used together.

What are the important considerations in user interface design?

Since user interface design links users to your app or website it is highly important. Some considerations of user interface include easily navigable menus that are clearly labeled with a simple design and user testing prior to launching to see what works and what doesn’t. Also label everything clearly so that it is easy to understand and use appropriate typography.

What does a UX designer do?

A UX designer is concerned with the entire process of acquiring and integrating a product, including branding, design, usability, and function. UX designers are responsible for product research, creating personas and scenarios, and information architecture. They also create wireframes, prototypes, and product testing.
