VERITAS approach for parameterization of psychological and behavioral models

Abstract

This paper focuses on the description of the approach used to parameterize the psychological and behavioural user models developed under the FP7 EU Founded project VERITAS: Virtual and Augmented Environments and Realistic User Interactions To achieve Embedded Accessibility DesignS. The present paper will focus on the methodology used to define the relevant psychological and behavioural parameters within the context of VERITAS. Two complementary approaches have been selected: on one hand, the use of existing models of the cognitive architecture Adaptive Control of Thought-Rational (ACT-R) for cognitive simulation purposes; on the other hand, a second approach based on existing metrics coming from medical and human behavior studies and biomedical models. © 2012 Springer-Verlag.
