Human-Computer Interaction

Human-Computer Interaction

Overview

Human-Computer Interaction (HCI) is a multidisciplinary field of study focused on the design, evaluation, and implementation of interactive computing systems for human use. It bridges the gap between Computer Science, Cognitive Psychology, and Design, examining how humans interact with computational technologies.

Key Components

Usability

Usability is a critical aspect of HCI, measuring how effectively, efficiently, and satisfactorily a user can interact with a computer system. It encompasses:

• Ease of learning
• Speed of task completion
• Error prevention
• User satisfaction

Interaction Modalities

HCI explores various interaction methods, including:

• Graphical User Interfaces (GUI)
• Voice interactions
• Touch interfaces
• Gesture recognition
• Augmented Reality interfaces

Theoretical Foundations

Cognitive Models

HCI relies on understanding human cognitive processes, including:

• Information processing
• Mental models
• Perception and attention
• Decision-making strategies

Emerging Technologies
