HCI Foundations: Designing for Human and Computer Capabilities

Great digital design isn't just about aesthetics; it is about understanding how humans process information and how computers receive and display it. If you want to build interfaces that feel natural and intuitive, you must first understand the cognitive and physical limits of both the user and the machine. This text-based course guides you through the fundamental principles of Human-Computer Interaction (HCI). You will learn how to analyze human perception, memory, and attention, and map these constraints to modern computer input-output capabilities. By studying these interactions, you will gain the skills to write clear, user-centric design specifications and improve the usability of any digital product. What you'll learn: Understand foundational HCI terminology, core concepts, and the history of user-centric design; Analyze human cognitive limits, including short-term memory constraints, visual perception, and attention spans; Evaluate computer input-output channels, from traditional keyboards and screens to modern touch, gesture, and voice interfaces; Apply accessibility best practices to ensure your designs accommodate diverse physical and cognitive abilities; Practice evaluating interface usability through written step-by-step cognitive walkthroughs; Design intuitive workflows that minimize cognitive load and prevent user errors. You will begin with essential terminology and the psychological models of human information processing before moving into computer hardware constraints. Through written explanations, real-world design scenarios, and practical analysis exercises, you will learn how to bridge the gap between human psychology and technical execution. This course is designed for beginners, including aspiring UX/UI designers, product managers, and software developers, with no prior experience in psychology or hardware design required.
