“…In COGNET (Ryder, Weiland, Szczepkowski, & Zachary, 1998), the role of the perception mechanism is to transfer the data obtained from the external world to the cognitive processor. In the initial version of COG-NET, this role was played by model components designated as "demons," which basically converted the input data into the symbolic format used by the cognitive model, paying little attention to modeling human perception mechanisms.…”

An important property of intelligent virtual agents (IVAs) and multiintelligent virtual agents systems (mIVAS) is their capability to acquire/perceive information from their environment. In this paper we present an auditory perceptual model for IVAs and mIVAS, which extends and reinterprets the key concepts of one of the awareness models developed for computer supported cooperative work (CSCW) applications, the spatial model of interaction (SMI). This perceptual model also introduces some factors typical of human perception-such as auditory acuity-as well as others associated with the sound source and its propagation with the aim of making perception in this kind of system more humanlike.

“…In one successful application, Computational Cognitive Modeling (Ryder et al, 1998) was used to design a telephone operator workstation where the jobs of multiple telephone operators were combined into a single role. Since each individual job was previously performed using a different workstation, the problem was to design a new workstation that supported all of the jobs -while maximizing call-processing efficiency and minimizing retraining of existing operators.…”

We are concerned with three challenges in the design of military Command and Control (C2) systems, namely: the demand for "smaller" organizations, the demand for "better" coordination (human-system, human-human and system-system) and the demand for "faster" execution. Driven by these demands, we performed a survey of Cognitive Engineering techniques with an eye towards how they can improve Systems Engineering efforts. This paper outlines our three challenges (smaller, better, faster) and reviews three successful applications by other Cognitive/Systems engineers faced with similar challenges. The applications employ Computational Cognitive Modeling (to address a demand for smaller), Cognitive Work Analysis (to address a demand for better) and Goal-Directed Task Analysis (to address a demand for faster). These three successes provide a practical roadmap for using Cognitive Engineering methods to address Systems Engineering problems in C2 as well as other domains.

Although, at this moment, there are not many researches on perceptual models for Intelligent Virtual Agents, the few that exist are more focused on visual than on hearing perception. This paper describes the work that the Universidad Politécnica de Madrid, in collaboration with the University of Nottingham, is carrying on, with the aim of endowing Intelligent Virtual Agents with a synthetic model of human-like hearing perception. We have based the design and development of this model on Endsley studies about situational awareness [10,11], where perception can be understood as the first level of awareness. This perceptual model also extends and reinterprets the key concepts introduced by a CSCW model of awareness known as the Spatial Model of Interaction [4]. In this paper, we give an overview of those studies related to our work and we describe how we have achieved our purposes: selecting an agent architecture; re-defining and reinterpreting the set of key concepts introduced by the Spatial Model of Interaction; and analysing those factors that make the auditory perceptual model more realistic. We also expose how a mathematical function can describe the agents clarity of perception and how this model of perception has been implemented and evaluated.
