Practical Considerations
How should the educator redirect learners during an enactment?
- Sometimes learners lose focus or become stalled while enacting a virtual simulation. The facilitator can use questions to redirect the learner and can directly or indirectly suggest different methods to work through the problem.
- A simulated overhead PA system can be built into the scenario using the facilitator as the voice of the PA. This may be useful when a direction needs to be conveyed to the learner without disrupting the flow of the scenario and is incorporated directly into the simulation itself. For example, learners using a simulated defibrillator forget to give the “all clear” command.

What are some practical considerations regarding enacting virtual simulations?
Participation in synchronous simulations requires learners to have reliable high-speed internet access, a computer/device (ideally with a webcam), and a headset with a microphone. An overview of the human-hardware-software components and process is shown in Figure 4.2.
Personal Computer:
Learners will need regular access to a computer, preferably a personal computer, with administrator privileges and be comfortable managing software and hardware. For an optimal experience learners need to have a laptop or desktop computer (Windows 10 or higher or Mac OS X 10.14 or higher is recommended). They may need to verify computer software if using a head mounted device as these often require the computer to have a graphics card and at least 8GB + RAM available to run the program software. Refer to the technical data sheets of the equipment being used for the virtual simulation for up-to-date technical requirements.
Head Mounted Device:
The most common head mounted displays that are available in educational settings include: Oculus RIFT, Oculus QUEST, and the QUEST2, Microsoft Halolens, or an Android or iOS phone in some instances. Generally cost is a factor for the institution but it does depend on who purchases the head set.
Internet Connection:
High speed broadband access (LAN, Cable or DSL) is highly recommended for an optimal learning experience. Note, that relying on a library or a café for internet access is not recommended.
A Web Browser is required for access to many learning systems and/or applications. In some instances it may be necessary for some users to upgrade their web browser programs. Refer to the technical data sheets for up- to- date browser requirements.
Speaker, and Headphones:
When enacting virtual simulations learners may have synchronous (live) online meetings using webinar software. It is preferable to use headphones with an attached microphone for these sessions.
Software:
Many courses require word processing software (such as Office 365).
As shown in Figure 4.2 In order for the learner to have a fully immersive experience the activity must meet the criteria shown in the diagram. This depends on the type of immersive experience you are looking for.
For example, in order for a student not to experience nausea during a virtual reality experience with a virtual headset (moving their head), the resolution must be less than 3 milliseconds. This is called pixel persistence. Moreover, this image shows the links between the human (learner), the equipment and the applications (experience) that is possible.
