Evolution of User Interface - an Interview with Emily Potts

Evolution of User Interface - an Interview with Emily Potts, Editor of Rockport PaperInc online magazine.


What is a User Interface? How did it all begin?

A User Interface (UI) is the virtual point of contact between a user and a digital product. When a user interacts with a device there are five main actors: the user, the physical point of contact, the virtual point of contact, the software itself, and the hardware device where the software is running. The earliest type of interface was called Command Line Interface, where a keyboard was used to access a program in a computer using a set of commands. In this case, the keyboard is the physical point of contact, the set of commands is the virtual point of contact, the program itself is the software that reacts to the set of commands, and the computer is the hardware device as shown in Figure 1.

I work with a few phone companies programming a few mobile apps to test the mobile phones. It is a QA test. Not all the companies are so rigorous.
