Virtual reality (VR) has been used to simulate the conditions of all kinds of emergencies, such as fire evacuation, earthquake evacuation, or confined space rescue. Previous studies have examined topics including the player's navigation in an emergency and the difference between the user's perception of visual guides in VR and real life. Often, these evacuation scenarios are presented only in broad daylight, with nothing obstructing the player's vision. The logical next step is to explore the possibilities of visual guides in emergency situations with reduced visibility. The visual guides should focus on the orientation in the emergency scenario's space and on correct decision-making (e.g., whether to take an elevator or stairs, how to deal with obstacles). The result may serve educational purposes on how to behave in emergencies and as a basis for evaluating new visual guides for orientation and correct decision-making in emergency situations. The student ought to research the current development in VR emergency simulations and determine the exemplary usages of emergency visual guides in them, as well as commonly used and newly proposed real-life guides that would benefit the VR environment. Then they should situate these guides in an experimental fire evacuation scenario with reduced visibility (e.g., by introducing smoke) and optimize it for VR purposes. This setup is then evaluated in the comparative user study, in which the participants follow the same script using different visual guide settings.
