“…This is in contrast with general VMS practice in which lights generally flash alternatively (Dudek, 1991). The flash rate of the lights is 1.0 Hz since previous experimental research (Nilsson, 2009) demonstrates that this flashing rate enhances the degree of perceived urgency (cognitive affordance) without creating a flashing effect which may annoy motorists, as investigated in laboratory experiments (Ronchi et al, 2015).…”

“…These use cases can be divided into three categories according to their purposes: (1) the use of VR as a general-purpose tool for emergency research and analysis [32]; (2) the use of VR to study human behaviors under fire situations such as route choice [33] and decision-making [34]; and (3) the use of VR to analyze environmental factors in fire evacuations, such as the location, form, quantity, and layout of evacuation aids [35]. If VR experiments can be conducted in multi-user collaborative environments, the virtual world will be greatly enhanced with realistic social interactions, and therefore may improve the validity of experiments.…”

Due to their strong immersion and real-time interactivity, helmet-mounted virtual reality (VR) devices are becoming increasingly popular. Based on these devices, an immersive virtual geographic environment (VGE) provides a promising method for research into crowd behavior in an emergency. However, the current cheaper helmet-mounted VR devices are not popular enough, and will continue to coexist with personal computer (PC)-based systems for a long time. Therefore, a heterogeneous distributed virtual geographic environment (HDVGE) could be a feasible solution to the heterogeneous problems caused by various types of clients, and support the implementation of spatiotemporal crowd behavior experiments with large numbers of concurrent participants. In this study, we developed an HDVGE framework, and put forward a set of design principles to define the similarities between the real world and the VGE. We discussed the HDVGE architecture, and proposed an abstract interaction layer, a protocol-based interaction algorithm, and an adjusted dead reckoning algorithm to solve the heterogeneous distributed problems. We then implemented an HDVGE prototype system focusing on subway fire evacuation experiments. Two types of clients are considered in the system: PC, and all-in-one VR. Finally, we evaluated the performances of the prototype system and the key algorithms. The results showed that in a low-latency local area network (LAN) environment, the prototype system can smoothly support 90 concurrent users consisting of PC and all-in-one VR clients. HDVGE provides a feasible solution for studying not only spatiotemporal crowd behaviors in normal conditions, but also evacuation behaviors in emergency conditions such as fires and earthquakes. HDVGE could also serve as a new means of obtaining observational data about individual and group behavior in support of human geography research.

Abstract. With the development of computer technology, the virtual reality technology has become more and more widely used in military field. The training of high-tech ammunition has the problems of low efficiency, high cost, poor security and inconsistent working mechanism. This paper fully analyzes the construction objectives and main contents of the high-tech ammunition virtual training, and applies virtual reality technology and Vega Prime to achieve the simulation of the process of a rocket weapon system to combat the target. This paper also makes further research on the technology of rocket trajectory calculation, real-time collision detection, etc., and achieves the whole process of combat simulation of the weapon system. The establishment of the system opened a new dimension of the military ammunition combat training .
