Abstract
-
User interfaces can be difficult to master. Typically, when problems occur, computers respond with generic, difficult-to-interpret feedback. This thesis presents Proactive Interactive Adaptive Computer Help (PIACH), a framework for a new style of computer help to alleviate these problems. The framework includes a scenerio and an architecture for realizing that framework. In this scenario, a proactive interface attempts to anticipate the needs of a user and responds interactively as the user is typing. It records and analyzes user actions to adapt computer responses to the individual, offering useful help information even before the user requests it.;The approach utilizes dynamic models of both the user and the domain the user is learning. These models facilitate and guide user goals. The feasibility of a system that can adapt to a user's level of proficiency during a computer session has been demonstrated by an implementation called COgnitive Adaptive Computer Help (COACH). COACH was first used to demonstrate PIACH for the domain of writing Lisp programs. The PIACH architecture was designed to facilitate developing and studying adaptive help systems; the help given the user, the domain in which the user is being coached, even the way the system adapts to the user, are represented in frames and controlled by rules which can be changed. A PIACH system for the UNIX command language domain was created with COACH to demonstrate its use as a shell for developing adaptive help systems. A study showing that an adaptive computer interface can improve user confidence and productivity validates the effectiveness of the approach.
