Interaction design and user experience fundamentals

Interaction design (IXD) and user experience (UX) design are increasingly recognized as essential skills for the web, mobile devices, and other digital interfaces and devices. But IXD and UX are much more than creating rollovers, knowing where to put buttons, and using attractive graphics and transitions. We need to understand what people need or want to do, what motivates them, how they interact with a device or interface, and we need to understand the technologies that are providing access to a nearly unlimited amount of information.

In this new fundamentals series David M. Hogue, Ph.D., an applied psychologist and UX designer, introduces the foundations of interaction design from a psychological perspective. Dave looks at the origins of interaction design and our basic need to record, understand, modify, communicate, share, and play with information. He also investigates key concepts in cognition, perception, learning, memory, and motivation to show how understanding the needs and behaviors of the people who will use the interface can inform and guide our design decisions.

The series is centered around five essential principles of interaction design: consistency, perceivability, predictability, learnability, and feedback. Dave uses the five principals to explore user experience and interaction design from a psychological perspective and to help explain how to craft more successful, usable, and enjoyable interfaces. His discussion covers a wide range of topics including how people develop a sense of place, cognitive friction, the Gestalt Principles, mental models, and perceived affordances.

The Interaction Design Fundamentals course is targeted at designers and developers who want to craft better, more engaging, experiences for their visitors and customers. Whether you are new to the field or are already creating interfaces for the web and devices, looking at interaction design from the perspective of human behavior, cognition, and motivation can help improve your design decisions overall.
