Because of their common interest in performance support, and common external influences such as cognitive psychology and digital technologies, roles and tools within these fields are beginning to converge, resulting in unprecedented overlap. The purpose of this paper is to explore the similarities, differences, and emerging trends among some of these fields and to gain insights into how their evolution affects performance support. Part 2, will be available in fall 1999, and it will present a typology for examining how interactivity applies to user assistance, with a variety of examples. Current interactive user interface construction tools are often more of a hindrance than a benefit during the early stages of interface design. These tools take too much time to use and force designers to specify more of the design details than they wish at this stage.
Most designers prefer to sketch early interface ideas on paper.
I have developed an interactive tool called SILK that allows designers to quickly sketch an interface using an electronic pad and stylus. However, unlike a paper sketch, this electronic sketch is interactive. The designer can illustrate behaviors by sketching storyboards, which specify how the screen should change in response to end-user actions. Minding the Store. How to make your knowledge systems more secure without discouraging openness.
