Principles underlying the design, evaluation and implementation of interactive computing systems as well as the major research topics associated with such systems. Technical breakdown of interfaces that are multi-media based front-ends to complex networks. Graphical user interfaces will be introduced along with the related physiological and human factors issues. Design of interfaces using virtual reality, the Internet, and other advanced development tools. Commonly integrated media such as video, graphics, and audio capabilities will be examined. User-centered technology will be a primary theme using the design of web pages and medical device design as hands-on applications.
