Historical evolution of HCI:
Introduction :
HCI stands for human computer interaction. It is also known as man machine study , human computer interface. Human computer interaction is the study of interaction between humans and computers. It deals with the design execution of computer system and phenomena that is of human use. HCI is used in all the places where the installation of computers are possible , HCI has distinctive inportance are :
COPMUTER SCIENCE
PSYCHOLOGY
SOCIALOGY
INDUSTRIAL DESIGN
Human:
Humans are the users of computers , who are getting benefits from the computers such as perform operations and functions etc. They can use the computers in every field of life in the form of PCs , mobiles , tablets , cars etc.
Computer:
Computer is an electronic machine which gets input from the user , process on that input and give the desired output of that input to the user. Simply it provides benefits to the user.
Interaction:
Interaction means the communication between human and computer. How user can interact with the machine? what are the effects of computer on human health? Is the machine’s interface is comfortable for the user? etc.
Historical Evolution:
Human Computer Interaction is an area of research and practice that emerged in the late 1970s and early 1980s, initially as an area in Computer Science. HCI has expanded rapidly and steadily for three purposes, attracting professionals from many other disciplines and incorporating diverse concepts and approaches.
1970s- The rise of the Personal Computer.
The broad project of computer science, which incorporated psychology, artificial intelligence and the philosophy of mind, had formed at the end of the 1970s.
1980s- Graphical User Interface (GUI).
Graphical User Interface (GUI) is the interface that is designed for the easier understanding of the users of the computers. Before GUI, there was a command prompt by which command was given to the computers. GUI started the graphical interface which is easy to use, understand, visualize, and it improved the working environment.
1990s- The Internet and Collaborative works.
The Internet started journey in 1990s. So, communications among people became easier. In the consequence of this, many new technologies arrived for better communication.
2000s- Mobile Computing and Beyond.
Mobile phones, PDA (Personal Development Assistance), and Smart Phones are ruling the present world. They offer a wide range of services to the people such as sms, mms, multimedia, games, email, internet, chatting, video conference, GPS etc.
Now a days the HCI is used in the area of Cognitive Science. With the help of the Internet, medical facilities can be provided remotely. Different interactive interfaces are designed those can be used for the cognitive rehabilitations.
Research Trends:
- Ubiquitous Communication:
People have to communicate through high speed local networks, nationally over wide-area networks, and portably via infrared, ultrasonic, cellular, and other technologies. Data and computational services need to be portably accessible from many if not most locations to which a user travels. It’s a challenging area of research.
- High Functionality Systems:
Systems have large numbers of functions associated with them. The main objective of HCI research is to make systems more usable, more useful, and to provide users with experiences fitting their specific background knowledge and objectives. So, it is a challenging area for researchers to develop the High Functionality Systems.
- Mass availability of computer graphics:
Computer graphics capabilities such as image processing, graphics transformations, rendering, and interactive animations etc. are the areas of research.
- Mixed Media:
