The ARP Virtual Reality System in Addressing Security Threats and Disaster Scenarios

Abstract

Nations, corporations and political organizations around the world today are forced to deal with an increasing number of security threats. As a result, various organizations must find ways to adequately equip and prepare themselves to handle numerous dangerous and life threatening circumstances. Virtual reality is an extremely important technology that can be used across a variety of different fields and for a number of diverse applications, ranging from simulation training to visualization tools, in order to prepare for and manage disaster situations. Head mounted display (HMD) virtual reality systems attempt visually to immerse the user in a virtual environment. However, it is well recognized that latency, the delay in responding to a user's head movement, is a major shortcoming that plagues immersive HMD virtual reality systems. Excessive latency destroys the illusion of reality that such systems attempt to present to the user. A hardware architecture known as the address recalculation pipeline (ARP) and a computer graphics rendering technique called priority rendering, were designed to reduce the end-to-end latency suffered by immersive HMD virtual reality systems. This paper discusses the benefits of using the ARP virtual reality system in addressing security threats and disaster situations.

Human Factors Research in Immersive Virtual Reality Firefighter Training: A Systematic Review

“…There has been a lot of interest in VR technology for the training of emergency response employees. For example, the development of VR disaster response scenarios has gained popularity [see, for example, (Chow et al, 2005;Vincent et al, 2008;Sharma et al, 2014)] since it enables cost-effective training of large-scale exercises and offers immersive properties that are difficult to replicate in desktop monitor-bound training.…”

Human visual perception of region warping distortions with different display and scene characteristics

“…Region warping involves the perturbation of shared object vertices in order to force these vertices to align, thereby eliminating any discrepancy between the vertices during user translations. Two methods of interpolation for region warping were introduced in Chow et al (2005b), linear interpolation and quadratic interpolation. Before warping could be performed, the exact amount of perturbation had to be known.…”

“…Both linear and quadratic region warping methods were tested in this experiment. In Chow et al (2005b) it was concluded that the distortions in the frames generated using quadratic region warping were concentrated further away from the user and were more similar to normally rendered frames, compared to frames rendered using linear region warping. This conclusion however was based on mathematical comparisons and did not reflect human visual perception of the distortions.…”

“…The quality of frames produced by implementing the region warping technique has previously been investigated using mathematical analysis (Chow et al 2005b). However while mathematical analysis gave an indication of the level of distortion caused by region warping, it did not incorporate the human visual perception of the distortions.…”
