In recent years, there has been an increasing interest in tangible sports simulators with the success of golf simulator. The main purpose of this study is to develop a tangible snowboard simulator for the beginner using virtual reality technology. This paper proposes an interactive virtual coach and high fidelity virtual environment for snowboard training. The virtual coach offers an intuitive guidance and personalized coaching feedback about the 5 fundamental riding skills. The virtual training environment uses the stereoscopic display system and motion platform to create more realistic training situation. We expect virtual reality will be used as a training aids in many sports such as taekwondo, baseball, archery and so on.

The purpose of this study was to investigate the effects of virtual reality game based training on balance and upper limb function in subacute stroke patients. Thirty patients with subacute stroke were randomly assigned to experimental groups(n=15) and control groups(n=15) applying virtual reality game-based training programs. Intervention is applied three times a week for 6 weeks, 30 minutes for 1 time. In the study group, there was a significant improvement in balance ability, upper extremity function, and trunk impairment scale(p<.05), and the difference between the two groups was significant in the BBS, TUG, TIS(p<.05). Based on these results, the virtual reality game based training program is clinically useful exercise program for subacute stroke patients.

Purpose: In this study, we investigated the effectiveness of a 12-week virtual reality exercise program using the Nintendo Wii console (Wii) in improving balance, emotion, and quality of life among patients with cognitive decline. Methods: The study included 30 patients with cognitive decline (12 female, 18 male) who were randomly assigned to an experimental (n=15) and control groups (n=15). All subjects performed a traditional cognitive rehabilitation program and the experimental group performed additional three 40-minute virtual reality based video game (Wii) sessions per week for 12 weeks. The berg balance scale (BBS) was used to assess balance abilities. The short form geriatric depression scale-Korean (GDS-K) and the Korean version of quality of life-Alzheimer's disease (KQOL-AD) scale were both used to assess life quality in patients. Statistical significance was tested within and between groups before and after treatment, using Wilcoxon signed rank and Mann-Whitney u-tests. Results: After 36 training sessions, there were significant beneficial effects of the virtual reality game exercise on balance (BBS), GDS-K, and KQOL-AD in the experimental group when compared to the control group. No significant difference was observed within the control group. Conclusion: These findings demonstrate that a virtual reality-training program could improve the outcomes in terms of balance, depression, and quality of life in patients with cognitive decline. Long-term follow-ups and further studies of more efficient virtual reality training programs are needed.

HMD makes big issues about virtual reality in these days. Experience of virtual reality may cause different effects with experience of real world, so this is the reason why comparison studies are needed. There are many works about usefulness of virtual reality education but most of studies were considered as special training. This study was started for the long term memory effect of virtual reality education game. Difference study of memory between real world education game and virtual reality education game shows virtual reality system has smaller diminution of memory than real world. And environment existence was defined as a main effect of long term memory through the test.

This study conducted the following experiment to examine change of physicopsychological function on lumbar stabilization exercise(LSE) and virtual reality game training(Nintendo Wii Sport-NWS) to stroke patients subject for fall prevention. Psychological function was measured by falls efficacy with stroke patients and physical function was measured by static and dynamic balance on comparative analysis of pre, post exercise and each groups in 30 stroke patient subject. Static balance was measured by BBS, FRT, dynamic were measured by TUG, 10m walking test and falls efficacy with stroke patients was measured index of falls efficacy. These result lead us to the conclusion that each group were statistically improved at all physicopsychological test, but BBS, FRT, 10m walking test were more statistically improved at LSE group and falls efficacy with stroke patients were more improved at virtual reality game training group. Consequently, virtual reality game training would be lead to positive increment of physicopsychological function on stroke patient.

In this paper, we will discuss planning and production of VR contents for effective racing drone steering training. In the real world, direct racing drone training training is obviously a space and economic limit. We propose through the production of VR-based drone infiltration action game as a solution to these limitations and try to improve effective drone handling ability. Especially, we designed the virtual reality contents in a similar environment by using the similarity of FPV goggles and HMD based VR, and designed virtual drones, maps and obstacles considering the characteristics of the structures used in racing drone and drone racing. Also, we tried to increase the user's immersion and presence by increasing difficulty level of obstacles.

Interactive simulators that simulate mechanical systems are being developed for the purpose of performance evaluation of product design, replacement of physical training, and entertainment game. Use of flight simulator is increasing to reduce risk and cost of physical training, and we need virtual environment which covers large area terrain. We need a method that can reduce development cost and construction time of virtual environment that simulate the real environment. There have been attempts to link GIS or remote sensing field with virtual reality. This paper examines a method that helps to construct virtual environment, and attempts to link geographic information with virtual reality. A construction method of virtual environment based on digital map and satellite image has been studied.

The purpose of this review was to investigate feasibility of intensive virtual reality training to improve upper extremity function with brain plasticity of individuals with stroke through the literature. The recovery of the paretic upper extremity depends on regularity and intensity of training as use-dependent plasticity. In resent, virtual reality program has been widely used in the occupational therapy field of augmented stroke rehabilitation. There is a growing body of evidence that virtual reality training of the paretic extremity induces brain plasticity associated with motor improvement. In terms of therapeutic feasibility to improve paretic upper extremity, recent research has explored several important factors of virtual reality training for recovery of upper extremity motor function. These factors include high repetition intensity, high motivation like type of game, enhanced multisensory feedback regarding performance, and interactive task-oriented training. Therefore, occupational therapy combined with intensive and repetitive virtual reality training will enhance recovery of upper extremity motor function after stroke.

Objective : This study was the influence of the training program using virtual reality on eye-hand coordination in children with developmental disordered. Methods : Six children(5 males, 1 female)with developmental disordered were recruited and randomly assigned to the control group(n=3) and the experimental group(n=3). Three children in the control group performed a fifty minutes of SI program ten times for ten weeks. In the experimental group, the other three children underwent a fifty minutes of SI program and virtual reality game. K-DTVP-2(Korean Developmental Test of Visual Perception)was used to measure the eye-hand coordination. Results : After a ten weeks of training program, there were significant differences in the eye-hand coordination in the experimental group. Conclusion : The training program using virtual reality games influenced for improving at the eye-hand coordination in children with developmental disordered.
