Human-Computer Interaction Basics

Human-Computer Interaction (HCI)

• Defined as the study of how people interact with computers and design technologies that let humans interact with computers in novel ways.
• Aims to create technology interventions that significantly impact individuals.

Interaction Framework

• Comprises components of interaction, emphasizing effective mapping between user and computer.
• Good mapping enhances usability, whereas bad mapping can hinder the user experience.

Fundamentals of HCI

• Focuses on both the human experience and the computer side of interactions.
• Involves understanding user needs, preferences, and the limitations of technology.

Interaction Design

• Key aspect of HCI, involving the design of user interfaces and experiences.
• Encompasses several stages, from conceptualization to prototype testing and user feedback.

Sensation and Perception

• Differentiates between distal (external stimuli) and proximal (sensory input) stimuli.
• Emphasizes the difference between sensation (initial detection) and perception (interpretation).

Perception Processing

• Discusses binding in perception, linking sensory input to meaningful experiences.
• Contrasts bottom-up perception (data-driven) with top-down perception (concept-driven).

Emotional and Reflective Processes

• Identifies visceral, behavioral, and reflective emotional processes in user interactions.
• Mental models shape how users understand and navigate technology interfaces.

Neurolinguistic Programming (NLP)

• Explores the NLP communication model, emphasizing how language affects user experience and interaction.
• Incorporates principles to enhance user understanding through effective communication strategies.

Spatial and Temporal Perception

• Highlights exocentric (external reference) and egocentric (self-referential) judgments in spatial awareness.
• Discusses depth perception and how various pictorial cues, such as linear perspective and shadows, influence user interpretation of space.

Pictorial Cues

• Explores different techniques to convey depth and dimension, including:
  • Relative and familiar size
  • Texture grading
  • Aerial perspectives
• These cues help users interpret visual information correctly and enhance user experience.

Conclusion

• Effective HCI design requires an understanding of various factors impacting human interaction with technology, including emotional, perceptual, and contextual elements.
