Virtual Reality Technology Prevents Accidents in Extreme Situations
Abstract
This research is aimed at examining the added value of using Virtual
Reality (VR) in a driving simulator to prevent road accidents,
specifically by improving drivers' skills when confronted with extreme
situations. In an experiment, subjects completed a driving scenario
using two platforms: A 3-D Virtual Reality display system using an HMD
(Head-Mounted Display), and a standard computerized display system based
on a standard computer monitor. The results show that the average rate
of errors (deviating from the driving path) in a VR environment is
significantly lower than in the standard one. In addition, there was no
compensation between speed and accuracy in completing the driving
mission. On the contrary: The average speed was even slightly faster in
the VR simulation than in the standard environment. Thus, generally,
despite the lower rate of deviation in VR setting, it is not achieved by
driving slower. When the subjects were asked about their personal
experiences from the training session, most of the subjects responded
that among other things, the VR session caused them to feel a higher
sense of commitment to the task and their performance. Some of them even
stated that the VR session gave them a real sensation of driving.

SUMMARY This paper presents the analysis of the stopping maneuver of the human driver by using a new three-dimensional driving simulator that uses CAVE, which provides stereoscopic immersive vision. First of all, the difference in the driving be- havior between 3D and 2D virtual environments is investigated. Secondly, a GMDH is applied to the measured data in order to build a mathematical model of driving behavior. From the ob- tained model, it is found that the acceleration information has less importance in stopping maneuver under the 2D and 3D en- vironments.
This paper considers opportunities to improve effectiveness of computer-based industrial training. Modification is made to an intelligent virtual reality-based training system to take advantage of the way people appear to respond to auditory and visual cues. Training scenarios are developed based on the idea that many times human errors in industry are shown to coincide with conditions that are infrequently encountered. Knowledge and auditory cues for different machining conditions for a computer-numerical-control (CNC) milling machine are built into the existing knowledge base. A simulated tool breakage that consisted of an animation, text and sound of glass breaking is integrated into a virtual training sequence and is triggered by the failure to stop operation in the poor cutting condition represented by sub-optimum spindle speed and cutting sound. A test is performed to check the transfer to the real world task. The simulated tool breakage is intended to help users take advantage of their tendency toward ‘dual coding’. An analysis is conducted to determine the impact of the simulated accident on decision-making performance in a real machining task. A disincentive is also introduced to assess the impact of potential tradeoffs between safety and performance that exist in the workplace. Results indicate that when a disincentive was introduced during the training task and the real task, mental workload was significantly higher, and operator decision-making performance was significantly improved when a simulated tool breakage was included in the training sequence. Some implications for researchers and practitioners are discussed.Relevance to industryResults obtained from this study indicate that virtual training with simulated accident may improve decision-making performance.
This Part II of a two-part paper presents the development of a prototype of the INtelligent TRaffic Evaluator for Prompt Incident Diagnosis using a Reality Engine (INTREPID-RE), a system that simulates a traffic accident site using virtual reality. While Part I emphasizes the construction of the user interface control panel and the 3D objects, this paper describes the development of the virtual reality algorithm, environment and models. During the simulation process, novice highway patrol officers wear a head-mounted display and a cyberglove to enter and view an accident scene that they create, and assess the magnitude and severity of the traffic accident. Based on their assessments, patrol officers establish an on-site traffic control strategy and coordinate parking of emergency vehicles that minimizes unnecessary traffic congestion. Officers use INTREPID-RE to secure a safe area for on-site patrol officers, create a channel to permit other drivers to pass the site, and dispatch highway patrol and emergency vehicles to the accident site. The interactive positioning function allows a virtual hand to simulate the positioning of emergency vehicles and clearing of accident vehicles on the road. Six domain experts who evaluated INTREPID-RE rated the system as good and agree that it has the potential to become a promising tool for training novice police officers.
This article explores immersive virtual reality as a potential educational strategy for nursing education and describes an immersive learning experience now being developed for nurses. This pioneering project is a virtual reality application targeting speed and accuracy of nurse response in emergency situations requiring cardiopulmonary resuscitation. Other potential uses and implications for the development of virtual reality learning programs are discussed.
