Multiple assessment for multiple users in virtual reality training environments

Abstract

With recent computational advances, several interaction devices can be used by different users who share the same virtual world, allowing the simulation of realistic environments, such as surgical rooms. In order to deal with this feature, assessment systems must be generalized to evaluate, individually, all users of the simulation and to make the aspects of their interactions known. In this paper we propose a new assessment system for training based on virtual reality which can evaluate more than one user at a time. The methodology proposed uses data collected from user interaction and group interactions during training to create user profile and group profile. The main advantages of that approach are: both of reports can be used to increase group performance and the interactions among users, during training, can be monitored to correct and improve group tasks in procedure such as sequential, simultaneous or collaborative tasks. © Springer-Verlag Berlin Heidelberg 2007.
