- Abstract
- Reports the basis for a cognitive walkthrough method to support the evaluation of multimedia presentations, e.g. 'how to do it' demonstrations. The walkthrough is founded upon an analysis of the cognitive processes and representations formed by the comprehension of the presentation. Issues include evaluation of attention, topic focus and information types. The walkthrough provides a series of guidelines for evaluation based on these cognitive models, such as the use of media, scripting and presentation techniques. The value of the guidelines is validated by several empirical studies. Reports an eye tracking study providing evidence as to how visual attention responds to multimedia materials. A series of comprehension studies then investigates the effectiveness of a presentation before and after the guidelines were applied. Illustrates with an example evaluation and studies of a commercially produced multimedia CD-ROM presentation on the etiology of cancer
