At the core of all usability is a design—the one being used by your customer. The blueprint or foundation of that design is found in the interaction design. Over the years, I’ve worked with many people, from clients to co-workers, who are involved in design but who don’t consider themselves “designers”. They usually have good design instincts, but don’t have a “design” background—and they are always asking me how they can become better “designers”.In this presentation, I distill the concepts of interaction design down to just the basics, to focus on what is most useful for non-interaction designers. Using the design process as a framework, I’ll provide an overview of the basic building blocks, design principles, and underlying structure of interaction design, and illustrate them using familiar real-world examples. Through these basic elements, I’ll discuss how design decisions are made, how to evaluate them at each level of an interaction design, and more importantly, what makes a “good” design decision. I will also discuss one or two emerging trends in interaction design and show how these basic elements can also be used to understand and evaluate them.This presentation won’t turn everyone into an interaction designer, but it will give you an understanding of the basics, and hopefully move you further along the road to being a better “designer”.
