What is UI?

UI definition: UI is an acronym of User Interface; it refers to the portions of a device, website, software, or application that a user interacts with.

UI applies to both the physical and virtual elements of a device; from the keyboard of a computer, through to the color palette of a website.

UI plays a strong role in branding and can impact:

• Brand consistency
• Brand identity
• Brand loyalty

For example:

The IKEA website uses its UI to showcase consistent:

• Colors
• Copywriting
• Images
• Product numbers

That pair with their offline, in-store, experience.
