Since real-life situations of trauma training are practically not available, a proper substitute must take advantage of the most recent advents in multimedia and groupware technologies. Multimedia visualization is of particular importance in trauma training, as the most crucial step of the patient's initial assessment is largely based on a surface check. Using trauma team training as a case in point, the long-term goal of a project by a group of Industrial Engineering and Management at Technion faculty, Israel Institute of Technology, is to design a domain-independent team training shell (TTS)--a generic scheme for team training application generator. It is expected to enable the creation of training executables in any domain that involves the need for coordination among team members charged with a common mission. The design of the TTS architecture requires the integration of concepts and techniques from multimedia-supported human-machine interaction environment, groupware-based team collaboration, networking and distributed applications and databases. Work is oriented towards obtaining synergy through integrating the benefits of groupware with multimedia. This paper describes the background and considerations involved in the TTS design by using the trauma team training as a case in point. A trauma scenario example with representative computer screens are offered as illustration. (Author)
