What is HCI? A STUDY ABOUT understanding how people interact with computers designing computer systems that are easy, efficient, and enjoyable to use. create user-centered designs that improve the interaction between humans and computers. Evolution of HCI 01. Machinery: The Early Days Early Early machinery designed primarily with functionality in mind, often neglecting usability. Evolution of HCI 01. The PC (Personal Computer) 1970s-1980s Shifting Focus to Usability In the the arrival of personal computers in the late 20th century marked a significant shift. PCs were designed for general consumers, not just specialists. Evolution of HCI 01. The GUI (Graphical User Interface) 1980s-1990s Making Computers Intuitive The Xerox Star 8010 Information System was the first commercial computer with a graphical user interface (GUI) Evolution of HCI 01. The Web 1990s-Present World Wide Web brought another revolution in user interaction. The web introduced new usability challenges. Evolution of HCI 01. Emerging technologies Ubiquitous Computing Augmented and Virtual Reality (AR/VR) Artificial Intelligence (AI) Voice and Gesture Interfaces Brain-Computer Interfaces (BCIs)  UNIVERSITY OF SCIENCE AND TECHNOLOGY OF SOUTHERN PHILIPPINES 2 Why Design for Usability? Designing For Usability HERE'S A BREAKDOWN OF THE KEY POINTS WHY WE SHOULD DESIGN FOR USABILITY: 02. Human Cognitive Psychology UNIVERSITY OF SCIENCE AND TECHNOLOGY 1. Perception - Designing interfaces that are visually clear and uncluttered helps users process information more efficiently. 2. Memory - Interfaces should minimize the cognitive load by not requiring users to remember too much OF SOUTHERN PHILIPPINES information from one step to the next. 3. Attention - Good design reduces the number of distractions and makes the important information stand out. Consistency and Standards 1. Internal Consistency - Ensures that similar operations and elements behave the same within the system. 2. External Consistency - Aligns with other systems users are familiar with. 02. UNIVERSITY OF SCIENCE AND TECHNOLOGY Visibility and Feedback 1. Visibility - Important functions should be visible without the user having to search for them. OF SOUTHERN PHILIPPINES 2. Feedback - Users need immediate feedback to understand the effect of their actions. This can be in the form of visual, auditory, or haptic responses. Affordances and Metaphors 1. Affordances - These are clues about how an object should be used. For instance, buttons look pressable. Properly designed affordances guide users intuitively. 2. Metaphors - Using familiar metaphors (like a trash can for deleting files) helps users understand new 02. concepts by relating them to something they already know. UNIVERSITY OF SCIENCE AND TECHNOLOGY Error Prevention and Recovery 1. Prevention - Provide constraints and suggestions that guide users away from errors. OF SOUTHERN PHILIPPINES 2. Recovery - Offer clear, helpful error messages and easy ways to undo actions or correct mistakes. Efficiency and Satisfaction 1. Efficiency - Good design enables users to achieve their goals quickly and with minimal effort. This includes optimizing workflows and reducing the number of steps needed to complete tasks. 2. Satisfaction - Usability leads to greater user satisfaction. When users find a product easy to use, they 02. are more likely to have a positive experience and continue using it.

Diciplines of HCI The field of HCI draws from a wide range of disciplines. These are the fields that have made significant contributions to HCI. Computer Science Provides the technical foundation for designing and developing software and hardware systems. 03. Psychology Offers insights into human behavior, cognition, perception, and learning, which are critical for designing UNIVERSITY OF SCIENCE AND TECHNOLOGY user-friendly interfaces. OF SOUTHERN PHILIPPINES Design Focuses on the aesthetic, functional, and usability aspects of user interfaces. Ergonomics and Human Factors Studies the physical and psychological interactions between people and systems, ensuring that systems are designed to fit the users’ needs. 03. Sociology UNIVERSITY OF SCIENCE AND TECHNOLOGY Helps us understand how people interact with technology in their social environments. It looks at how cultural norms, social behaviors, and group dynamics influence the way people use and perceive technology. OF SOUTHERN PHILIPPINES Language Explores how language is used in human-computer interaction, particularly in natural language processing and communication. Cognitive Science Studies the mind and its processes, including how people think, learn, and remember. 03. Artificial Intelligence (AI) Focuses on creating intelligent systems that can simulate human-like behavior and decision-making. UNIVERSITY OF SCIENCE AND TECHNOLOGY Communication Studies OF SOUTHERN PHILIPPINES Examines how people convey and interpret information, which is crucial for designing interfaces that facilitate clear communication. Engineering Provides the tools and methods for building reliable, efficient, and scalable systems. 03. Ethics and Philosophy Addresses the ethical implications of technology use and the philosophical questions surrounding human UNIVERSITY OF SCIENCE AND TECHNOLOGY interaction with machines. OF SOUTHERN PHILIPPINES Education Explores how technology can be designed to support learning and education. Reference Johnson, J. (2010).
