Abstract:

Rather than focusing on how the site looks, interaction designers are primarily concerned with how an application or Web site functions. They investigate whether the application or Web site performs the intended task in a predictable manner. Interaction design incorporates a lot of skills from other disciplines, such as technical writing and information architecture.
