“…As in the work on the TOOD method (Task Object Oriented Design ; (Abed et al 1998;Tabary 2001)) and the ICO (Interactive Cooperative Objects ; (Palanque 1997;Palanque 1992;Palanque et al 1995)), Petri nets are used to model human tasks in a HCI context ; this modelling method then proves to be useful for the specification of the interactive system. However, in the method dealt with in this article, unlike the methods mentioned above, the emphasis is placed explicitly on the notion of situation, leading to the identification of normal and abnormal (incident) situations.…”

This article presents a method for the modelling of cognitive activity using object Petri nets. The method includes the recognition of the various classes of situation (normal and abnormal) which human operators are likely to meet whilst performing their tasks. Each of these classes is described according to the characteristics of the state of the system. We will present the various mental representations used during the control/command activity according to the main aims set by the operator. The examples given come from a project dealing with the integration of a supervision system in a railway traffic regulation room.

“…Net related models have been proposed for modeling knowledge [12; 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24], determining requirements [25]. In addition, many meaningful netbased system models for software systems development have been proposed [26,27,28,29,30]. Some attempts to address the PN or CPN-based agent modeling problem can be found in [31,32,33,34].…”

This paper presents an agent-based approach to developing intelligent Virtual Reality-based training systems. The architecture of an intelligent Virtual Reality-based training system is modeled as five collaborative agents: training task-planning agent, simulation agent, performance evaluation agent, on-line instruction agent, and intelligent interface agent. The behavioral and knowledge models of each agent type and the mechanism of inter-agent interaction and coordination are described. A Petri Nets-based specification approach that gives the work formalism for effective modeling and implementation is elaborated. Finally, Computerized Numeric Control (CNC) milling operations virtual training prototype system is introduced to show the effectiveness of this approach.

In this paper we discuss a notation to describe task models, which can specify a wide range of temporal relationships among ta~ks. It is a compact and graphical notation, immediate both to use and understand. Its logical structure and the related automatic tool make it suitable for designing even large sized applications.KEYWORDS Task models, formal notations, model-based user interface design, tools for design.
