Human-Computer Interaction
The interdisciplinary field studying the design, evaluation, and implementation of interactive computing systems for human use and the surrounding phenomena.
Human-Computer Interaction
Human-Computer Interaction (HCI) represents the convergence of computer science, behavioral sciences, and design theory to create more effective ways for humans to engage with technology. This field emerged in the 1980s as computers became increasingly prevalent in everyday life.
Core Principles
The fundamental goals of HCI include:
- Usability: Creating interfaces that are easy to learn and efficient to use
- Accessibility: Ensuring technology is available to users of all abilities
- User Experience: Designing for positive emotional and psychological responses
- Human Factors: Considering physical and cognitive human capabilities
Key Components
Interface Design
The creation of visual and interactive elements that facilitate communication between user and machine, incorporating:
