An Academic Discipline : Studying people interacting with (computer) technology. A Design Discipline : Designing interventions for systems involving people and technology. Design - Three 'Use' Words Useful : Functional, performs tasks. Usable : Easy to use, performs the right tasks, enjoyable user experience. Used : Attractive, available, acceptable to the organization. Lecture 03 Principles and Foundations of HCI HCI combines three main research activities: Creating usability methods and Capturing user experience. Developing new systems, tools, and techniques. Modeling and understanding human behavior. Influence of Experimental Psychology Models human neuromuscular motor control and perceptual abilities. Focus on controlled experiment paradigm: Indepe...
Data Visualization Notes
Weber’s Law Kahneman's Thinking Stephen Few’s Perception - 3 Gestalt Principles - 6 Tufte’s Principles - 7 Munzner's Rules of Thumb - 6 L01 Introduction Definition of Visualization: Computer-based visualization systems provide visual representations of datasets to enhance task effectiveness. Purpose of Visualization: Augment human capabilities rather than replace decision-making with automated systems. Useful when fully automatic solutions are either unavailable or not trusted. Helps in exploratory analysis, presentation of known results, requirement assessment, and verification of automatic solutions. Role of External Representations: Replace cognitive processing with perceptual processing. Visual representations take advantage of the high-bandwidth human visual system, which processes information in parallel and pre-attentively. High-bandwidth channel to the brain, providing an overview with background processing. Vision supports simultaneous perceptio...
