User interface
User Interface
The User Interface (pronounced: yoo-zer in-ter-feys) is a term used in the field of Computer Science and Human-Computer Interaction to describe the space where interactions between humans and machines occur. The goal of this interaction is to allow effective operation and control of the machine from the human end, while the machine simultaneously feeds back information that aids the operators' decision-making process.
Etymology
The term "User Interface" is derived from the words "user" and "interface". The word "user" (pronounced: yoo-zer) is an English term that refers to a person who uses or operates something, especially a computer or other machine. The word "interface" (pronounced: in-ter-feys) is also an English term that refers to a point where two systems, subjects, organizations, etc., meet and interact.
Types of User Interfaces
There are several types of user interfaces, including:
- Graphical User Interface (GUI): This type of interface allows users to interact with electronic devices through graphical icons and visual indicators, as opposed to text-based interfaces, typed command labels or text navigation.
- Command Line Interface (CLI): This is a text-based interface used to operate software and operating systems while allowing the user to respond to visual prompts by typing single commands into the interface and receiving a reply in the same way.
- Touch User Interface (TUI): This is a type of interface that allows users to interact with a computer by touching icons or links on the screen.
- Voice User Interface (VUI): This type of interface allows users to interact with a system through voice or speech commands.
Related Terms
- User Experience (UX): This refers to a person's emotions and attitudes about using a particular product, system or service. It includes the practical, experiential, affective, meaningful and valuable aspects of human-computer interaction and product ownership.
- Usability: This is the ease of use and learnability of a human-made object such as a tool or device. In software engineering, usability is the degree to which a software can be used by specified consumers to achieve quantified objectives with effectiveness, efficiency, and satisfaction in a quantified context of use.
