Human-computer interaction is 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.
Accordingly, the three major elements of HCI research include:
- New interaction paradigms that enable users to communicate with computers and with others using computers in more effective, human ways.
- Fundamental understanding of the nature of interaction that will enable users to achieve their goals more directly, including a better understanding of the limitations of human information processing.
- Engineering methods for interactive system design and development that will improve the quality and reduce the costs of user interfaces for new systems.
Characteristics of Human Computer Interaction:
- Ubiquitous communication
- High functionality systems
- Mass availability of computer graphics
- Mixed media
- High-bandwidth interaction
- Large and thin displays
- Embedded computation
- Group interfaces
- User Tailorability
- Information Utilities
