Icon attributed to LUI[citation needed]
A live user interface (LUI, pronounced Loo-ee) is a type of user interface which allows people to interact with a computer and computer-controlled devices, utilizing the power of human interaction.
With a LUI, a computer representation of a live customer service representative could navigate with the user through the interface, and present images, maps and video clips from within the website. The computer representation can also help the user perform on-line purchases and complete complex forms.
LUI concept is founded on the principle that the best and most efficient user interface is based on a human interaction.
