If you have ever developed multimedia from a storyboard and discovered that your reviewers liked the storyboard but hated the product, or if you have purchased a multimedia title on the strength of the description on the packaging only to be disappointed in the real thing, you are well aware that the description of a multimedia program differs from the experience of using the program ,often by quite a lot. Delight is the facilitative component of experience.
Difficulty is the challenging component of experience.
At first glance it seems reasonable to postulate that designers should strive to create experiences in which delight is optimized and difficulty is minimized. Reviews of multimedia software suggest that,in fact, different groups of instructional multimedi a designers have tried either to optimize delight or to minimize difficulty. Unfortunately, neither approach results in optimal experience for most learning. At a fundamental level, the components that designers manipulate in creating experience are function and form. Function and form are not the same thing, although they are highly interdependent.
