Virtual reality falls on face6/8/2023 In addition to exposing workers to fewer real-world hazards during training, a key benefit of VR is greater efficiency, according to Justin Ganschow, business development manager for Caterpillar Safety Services, and Kim Shambrook, vice president of safety education, training and services at the National Safety Council. Hazards that may be clear from other perspectives can remain unseen by the operator. “The trainees feel quite immersed in the environment and find the training worthwhile with VR experience,” he said.Ī NIOSH simulation depicts the potential safety concern posed by a haul truck’s blind spots. The reception to the training has been “quite positive,” said Dick Hannah, vice president of innovation and learning at the council. The VR system provides data on the speed and spacing of welds and allows others in the classroom to see what participants are doing, providing them an opportunity to give feedback. Over the past three years, the Houston Area Safety Council has used VR to train welders. On a more occupational note, a 2011 study from Iowa State University published in the Welding Journal found that welding students who used VR for at least half their training performed better “across four distinctive weld qualifications” than students who received only traditional training. Likewise, a 2016 study led by researchers from China involving high school students found that participants had better retention of knowledge – as well as improved test scores – when using VR-based learning. When using the VR headset, the participants had a nearly 9% higher overall recall accuracy compared with using the computer. The participants used a desktop computer and a VR head-mounted display while going through the exercises. Researchers from the University of Maryland asked participants to remember the locations of famous faces in two virtual locations: a room in a palace and a medieval town. This immersive experience can lead to better memory retention, according to the results of a 2018 study published in the journal Virtual Reality. Hence, learners can leverage what psychologists call embodied cognition,” Bailenson writes. “What makes VR different from using a computer is that you move your body naturally, as opposed to using a mouse and a keyboard. Presence occurs when the body’s “motor and perceptual systems” interact with a virtual world just as they would in the physical world. In his book, Bailenson uses the terms “presence” or “psychological presence,” which he defines as “that peculiar sense of ‘being there’ unique to virtual reality.”īiomedical Engineer Jennica Bellanca demonstrates virtual reality and simulation programs at NIOSH’s Pittsburgh Mining Research Division. However, as in the judge’s case, potential hazards exist, as do questions about where VR fits in the spectrum of safety training. One major benefit is bringing trainees closer to real-world experiences without exposing them to real-world dangers. Thanks to its immersive capabilities, many organizations are making use of VR as a safety training tool. “It was a scary moment, but he was just fine,” Bailenson said. As a result, he slammed into a very real table – much to Bailenson’s horror. In one case, a federal judge dove in an attempt to save himself and catch an imaginary ledge after “falling off” the virtual platform. Others laugh, cry out in fear, throw out their hands to protect themselves, crawl on the ground or look around in wonder. Jeremy Bailenson, the lab’s founding director, writes in his 2018 book “Experience on Demand: What Virtual Reality Is, How It Works, and What It Can Do” that some visitors gasp during these types of VR experiences. Then, the floor begins to shake and the sound of an “industrial whine” is heard as you shoot into an illusionary world 30 feet above the ground on a platform connected to another by a thin walkway.įor many visitors to the Virtual Human Interaction Lab at Stanford University, one of their first experiences is “walking the plank.”
