![]() ![]() ![]() There are several key attributes possessed by all screen-based simulators that allow them to operate “intelligently” and provide an effective learning experience without the need for instructor presence (Table 14.1). While screen-based simulations can have high initial development costs, they do not require an instructor to be present while the trainee completes an exercise. Finally, screen-based simulations offer significant cost advantages over mannequin simulation. In the case of virtual reality simulators, even physical movements can be captured and tracked, a feature which renders them capable of driving trainees to higher levels of technical skill performance. Second, every correct or incorrect decision the operator makes during the simulation can be captured and tracked quite easily, rendering screen-based simulation highly suitable for developing or assessing competency in large groups of health-care providers. First, because screen-based simulations are entirely conducted on a personal computer or within a web browser, they offer unparalleled flexibility of the time and place in which the training exercises occur. Positioned somewhat lower on the fidelity spectrum are “conventional” screen-based simulators, which aspire to represent fewer aspects of the physical environment, yet demonstrate a degree of fidelity sufficient to refine clinical judgment and develop the cognitive structures that are required to execute complex tasks in a reliable manner.Īll screen-based simulators, regardless of their fidelity level, address some of the inherent disadvantages of mannequin simulation. These are highly sophisticated screen-based simulators that are capable of representing complex physical spaces in three dimensions while allowing multiple users to interact with virtual objects and animated versions of one another (“avatars”) within the virtual environment. Occupying the highest end of the environmental and psychological fidelity spectrum are “virtual reality” trainers. Screen-based simulators for health-care education now encompass a broad spectrum of fidelity, a term that describes the number and authenticity of sensory or environmental “cues” that the simulator provides as part of the context surrounding the clinical scenario it depicts. ![]()
