“…There are many different applications of a head-mounted display (HMD) based virtual reality (VR), but only a few studies integrated a virtual body in the context of sports applications (for review see [1]). Furthermore, VR is a promising tool for expanding the possibilities of psychological and sport training applications due to many aspects in the virtual environment that can be controlled and manipulated, which are not possible in a real-world setting [2].…”

“…At the present time, only a few numbers of studies included the whole-body visualization. In most studies, either nothing of the own body or only some body parts (in most cases the hands for better orientation) were visualized [1]. So far, whole body visualizations in HMD based VR were used for therapy [7] or for investigations of embodiment to analyze the link between central body representations and higher cognitive functions [14,23].…”

Effects of body visualization on performance in head-mounted display virtual reality

et al. 2020

Although there are many virtual reality (VR) applications in sports, only a handful of studies visualized the whole body. There is still a lack of understanding, how much of the own body must be visualized in the head-mounted display (HMD) based VR, to ensure fidelity and similar performance outcome as in the real-world. In the current study, 20 young and healthy participants completed three tasks in a real and virtual environment: balance task, grasping task, and throwing task with a ball. The aim was to find out the meaning of the visualization of different body parts for the quality of movement execution and to derive future guidelines for virtual body presentation. In addition, a comparison of human performance between reality and VR, with whole-body visualization was made. Focusing on the main goal of the current study, there were differences within the measured parameters due to the visualization of different body parts. In the balance task, the differences within the VR body visualization consisted mainly through nobody visualization (NB) compared to the other visualization types defined as whole-body (WB), WB except feet (NF), as well as WB except feet and legs (NLF). In the grasping task, the different body visualization seemed to have no impact on the participants' performances. In the throwing task, the whole-body visualization led to higher accuracy compared to the other visualization types. Regarding the comparison between the conditions, we found significant differences between reality and VR, which had a large effect on the parameters time for completion in the balance and grasping task, the number of foot strikes on the beam in the balance task, as well as the subjective estimation of the difficulty for all tasks. However, the number of errors and the quality of the performances did not differ significantly. The current study was the first study comparing sportsrelated tasks in VR and reality with further manipulations (occlusions of body parts) of the virtual body. For studies analyzing perception and sports performance or for VR sports interventions, we recommend the visualization of the whole body in real-time.

“…Especially when using Head Mounted Displays (HMDs), which separate the real from the virtual world, it would be necessary to visualize the athlete's body. Unfortunately, concerning the body visualization and also familiarization times in HMDs, there exist no concrete recommendations or standards, as there are no standards for the creation and the look of virtual characters either Petri et al [6]. Today, most VEs are only created for one user.…”

“…The technical limitations and the costs associated with the creation of virtual training environments pose a significant barrier for an uptake in VE sports training. Overviews of technical requirements for VEs can be found in Miles et al (2012) and Petri et al (2018). However, it is important to note that even if some sports are currently too challenging and costly to simulate with high fidelity, VEs might be still useful for observational learning (Tanaka, 2017).…”

Using Virtual Environments to Improve Real-World Motor Skills in Sports: A Systematic Review

2019

View full text Add to dashboard Cite

In many settings, sports training can be difficult to organize, logistically complicated and very costly. Virtual environments (VE) have garnered interest as a tool to train real-world sports skills due to the realism and flexibility that they can deliver. A key assumption of VE-based training is that the learned skills and experiences transfer to the real world, but do they? Using PRISMA guidelines, this systematic review evaluated the available evidence regarding the transfer of motor skills from VE training to real-world sporting contexts. The initial search identified 448 articles, but only 4 of these articles met basic criteria necessary to assess real-world transfer. Key factors regarding the study design, learner characteristics and training environment of these studies are considered. In a relatively new area of research, the findings from these 4 articles are encouraging and provide initial support for the notion that skills training in a VE can improve real-world performance in sports. However, for a wider uptake of VEs in sports training, it is important that more research demonstrates real-world transfer. Study design recommendations are suggested for researchers, developers or trainers who are considering demonstrating real-world transfers from virtual to real-world environments.
