ABSTRACT
The distinguishing characteristics of multimedia are information-intensive applications that have a complex design space for presenting information to people. Design of multi-media interfaces currently leaves a lot to be desired. As with many technologies, it is the fascination with new devices, functions, and forms of interaction that has motivated design rather than ease of use, or even utility of practical applications. Operational usability: It is the conventional sense of usability that concerns design of graphical user interface features such as menus, icons, metaphors, and navigation in hypermedia. Training and education are both important markets for multimedia and hence learnability of the product and its content are key quality attributes. However, design of educational technology is a complex subject in its own right, and multimedia is only one part of the design problem. Domain knowledge, including use of conventions, symbols, and terminology in the domain, is important because less-experienced users will require more complete information to be presented.
