Human Interaction and Computer

Field of human interaction and computer science is the study of how to design, evaluate, and implement an interactive computer system that can be used by humans easily. 
 
In the era of technology have now, almost whole life humans depending on the engine. Because so the importance of the machines for humans, the machines were then made ​​as easy as possible for use. Computer is a machine that created to help the life of humanity, to all fields, such as banking, education, government, trade, military, and so forth.
 
In computer technological developments, both hardware and software, is increasingly rapidly, although essentially the engine computer is very stupid, but humans can make it so smart. Humans have been provided and include various commands on the computer so the computer can perform a variety of jobs in want human.
 
Human-computer interaction is a discipline that examines the communication or interaction among the users with the system. The system in the intention here is not only the existing system on the computer but also which many systems in use in everyday life, such as household appliances and so forth.

Human and computer interaction (human-computer interaction, HCI) is the discipline of science that studies the relationship between humans and computers that include design, evaluation, and implementation of computer user interface for easy use by humans. While the human and computer interaction itself is a series of processes, dialogues and activities undertaken by humans to interface with the computer that the two are providing input and feedback through an interface to obtain the final result expected.

Some aspects that are the focus in the design of an interface is:

    1. The methodology and processes used in designing an interface.
    2. Interface implementation methods.
    3. Methods of evaluation and comparison of the interface.
    4. Development of new interface.
