Development of CSCW interfaces from a user-centered viewpoint: Extending the touche process model through defeasible argumentation

Abstract

The Task-Oriented and User-CenteredProcess Model for Developing Interfaces for Human-Computer-Human Environments (TOUCHE) is aimed to build up user interfaces for groupware applications under a Human-Computer Interaction perspective. It includes a large set of well known formal models like Class Diagrams, Organizational Structure Diagrams, Task Diagrams, Collaboration Diagrams and Abstract Interaction Objects among others. Most of such models, however, suffer from a number of limitations when formalizing users' commonsense. Over the last few years, Argumentation Systems have been gaining importance in several areas of Artificial Intelligence, mainly as a vehicle for facilitating rationally justifiable decision making when handling incomplete and potentially inconsistent information. This paper sketches a Proof of Concept to show how defeasible argumentation techniques can be embedded within the TOUCHE. The final goal is to enhance the capability of development process models for CSCW systems by including a rule-based approach for efficient reasoning with incomplete and inconsistent information. © 2009 Springer Berlin Heidelberg.
