Introduction[edit]

Humans interact with computers in many ways; the interface between humans and computers is crucial to facilitate this interaction. Desktop applications, internet browsers, handheld computers, ERP, and computer kiosks make use of the prevalent graphical user interfaces (GUI) of today.[5] Voice user interfaces (VUI) are used for speech recognition and synthesizing systems, and the emerging multi-modal and Graphical user interfaces (GUI) allow humans to engage with embodied character agents in a way that cannot be achieved with other interface paradigms. The growth in human–computer interaction field has been in quality of interaction, and in different branching in its history. Instead of designing regular interfaces, the different research branches have had a different focus on the concepts of multimodality[6] rather than unimodality, intelligent adaptive interfaces rather than command/action based ones, and finally active rather than passive interfaces.[citation needed]

The Association for Computing Machinery (ACM) defines human-computer interaction as "a discipline concerned with the design, evaluation and implementation of interactive computing systems for human use and with the study of major phenomena surrounding them".[5] An important facet of HCI is user satisfaction (or simply End User Computing Satisfaction). "Because human–computer interaction studies a human and a machine in communication, it draws from supporting knowledge on both the machine and the human side. On the machine side, techniques in computer graphics, operating systems, programming languages, and development environments are relevant. On the human side, communication theory, graphic and industrial design disciplines, linguistics, social sciences, cognitive psychology, social psychology, and human factors such as computer user satisfaction are relevant. And, of course, engineering and design methods are relevant."[5] Due to the multidisciplinary nature of HCI, people with different backgrounds contribute to its success. HCI is also sometimes termed human–machine interaction (HMI), man-machine interaction (MMI) or computer-human interaction (CHI).

Poorly designed human-machine interfaces can lead to many unexpected problems. A classic example is the Three Mile Island accident, a nuclear meltdown accident, where investigations concluded that the design of the human-machine interface was at least partly responsible for the disaster.[7][8][9] Similarly, accidents in aviation have resulted from manufacturers' decisions to use non-standard flight instruments or throttle quadrant layouts: even though the new designs were proposed to be superior in basic human-machine interaction, pilots had already ingrained the "standard" layout and thus the conceptually good idea actually had undesirable results.

Human–computer interface[edit]

Main article: User interface

The human–computer interface can be described as the point of communication between the human user and the computer. The flow of information between the human and computer is defined as the loop of interaction. The loop of interaction has several aspects to it, including:



  • Visual Based :The visual based human computer interaction is probably the most widespread area in Human Computer Interaction (HCI) research.

  • Audio Based : The audio based interaction between a computer and a human is another important area of in HCI systems. This area deals with information acquired by different audio signals.

  • Task environment: The conditions and goals set upon the user.

  • Machine environment: The environment that the computer is connected to, e.g. a laptop in a college student's dorm room.

  • Areas of the interface: Non-overlapping areas involve processes of the human and computer not pertaining to their interaction. Meanwhile, the overlapping areas only concern themselves with the processes pertaining to their interaction.

  • Input flow: The flow of information that begins in the task environment, when the user has some task that requires using their computer.

  • Output: The flow of information that originates in the machine environment.

  • Feedback: Loops through the interface that evaluate, moderate, and confirm processes as they pass from the human through the interface to the computer and back.

  • Fit: This is the match between the computer design, the user and the task to optimize the human resources needed to accomplish the task.

2. Difference Between GUI and CLI


The main difference between GUI and CLI is that the Graphical User Interface (GUI) allows the user to interact with the system using graphical elements such as windows, icons, menus while the Command Line Interface (CLI) allows the user to interact with the system using commands. 

An operating system is an interface between the user and the hardware components. It performs different tasks. An operating system provides GUI or CLI for the user to perform tasks. Some operating systems only provide CLI while others provide both GUI and CLI. A GUI consists of controls or widgets to interact with the computer. On the other hand, when using the CLI, the user should enter commands to perform the tasks. Overall, GUI is more user-friendly, but the execution speed is higher in CLI.






What is GUGUI stands for Graphical User Interface. It takes the advantage of computer graphics. It allows the user to interact with the computer using components such as windows, icons, labels, text boxes, and radio buttons. It is easy for the user to perform tasks using GUI as it does not require remembering commands. He can easily click on icons, drag and drop objects using the mouse.


are various GUI components. The window is the complete visible screen to the user. It has a rectangular shape and it can overlap with the area of other windows. A text box is a component for the user to enter inp
