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.

Intellectual disability affects all spheres of the lives of people can be who suffer from it. Unfortunately, modern medicine cannot cure intellectual disability. However, the quality of life improved by means of physical exercise. In this study, we compared the health-related physical fitness, metabolic syndrome index and mental health between a game biking group(5 participants) and a brisk walking group(4 participants). This study used a between-subject design and verified by non-parametric test. The participants performed an exercise program with warm up and resistance training for 12 weeks. A game bike was used for the physically impaired, where the individual looked at a screen and pedaled. The fasters he pedaled the faster the object on the screen movies. We measured health-related physical fitness, metabolic syndrome index and mental health. We also measured their perceived exertion and interest during the exercise by a visual analog scale. The results before and after the exercise program showed that health-related physical fitness, metabolic risk factors, mental health level were improved in both groups. As we hypothesized before the study, the game biking group showed a statistically significantly different level on the Rating of Perceived Exertion than the brisk walking group and a higher level on the Rating of Exercise Interest during the exercise program. Our results lead to a conclusion that an exercise program with the use of a game bike improve motivation for exercise participation in intellectually handicapped participants.

연구목적: 닌텐도 위를 이용한 가상현실기반 비디오게임 프로그램을 만성기 뇌졸중 환자에게 적용하여 균형능력 및 일상생활동작에 어떠한 영향을 미치는지 알아보고, 뇌졸중 환자의 재활프로그램으로서 적용 가능성이 있는지 알아보고자 한다. 연구방법: 만성기 뇌졸중 환자를 무작위로 가상현실기반 비디오게임 프로그램을 적용한 실험군(n=7)과 적용하지 않은 대조군(n=10)으로 구분하여 연구를 진행하였다. 연구에 참여한 모든 대상자에게 30분의 Bobath therapy와 15분간의 FES 치료를 기본적으로 실시하였다. 이에 더하여 실험군은 가상현실기반 비디오게임 프로그램을 1일 30분이내, 주 5회, 3주간 실시하였다. 대조군은 자전거 운동과 보행훈련으로 30분간 시행하였다. 실험 전 후 눈뜨고 외발서기(OLST; open leg standing test), Timed Up and Go(TUG) 검사, 10m 걷기 검사, Functional Independence Measure(FIM)를 측정하였다. 실험 전과 실험 후 측정값의 차이를 비교하기 위해 Wilcoxon Signed Ranks Test를 실시하였다. 그리고 각 측정값의 변화량에 대한 실험군과 대조군 사이의 차이를 알아보기 위해 Mann-Whitney U Test를 실시하였다. 연구결과: 실험결과는 다음과 같다. 1) 실험군에서는 FIM의 유의한 증가와 TUG, 10m 걷기 검사의 유의한 감소를(p<.05) 보였다. 대조군에서는 OLST의 증가와 TUG, 10m walking test의 감소가 나타났지만 통계적으로 유의하지 않았다. 오직 FIM에서만 유의한 증가가 나타났다(p<.05). 2) 실험 전 후의 실험군과 대조군의 각 측정값들의 평균차를 비교한 결과 실험군은 대조군보다 실험 전 후 OLST, TUG, 10m walking test 차이의 평균은 컸지만 통계적으로 유의하지 않았다. 결론: 이상의 결과로부터 가상현실기반 비디오게임이 만성기 뇌졸중 환자의 동적균형능력 및 일상생활동작 향상에 효과가 있음을 알 수 있었다.

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.

Most of the computer to implement a Augmented reality 3-D, or a graphic or visual means through the virtual space. The participants in the Augmented reality immersive virtual reality and virtual reality, the process proceeds to change the world. In particular, the field of children's games and Augmented reality fits well with the technical characteristics of the children that may lead to more interesting and creative sector is pointing to. In this study, children's games in order to maximize learning effectiveness of board games and Augmented reality technology, take a look at the characteristics of the children's educational program is to propose a new model proposal.

Due to improvements in the capabilities of commercial game engines, there are increasing instances of applying game engines to scientific visualization applications. This study describes a case of creating a virtual reality application that visualizes medical volume data based on the Unity3D game engine. When using a game engine, there is an advantage that various functions required for an application are basically provided, such as depth sorting of translucent objects or virtual reality hardware support. On the other hand, there is a restriction that the structure of the application program should be modified to suit the characteristics of the game engine. This paper describes a method for visualizing medical volume data using the structure of a game engine. As a result, we were able to create a virtual reality scene that consisted of surface data and medical volume data fragments together. And we confirmed the possibility of game engine as a future medical simulation production tool.

Age related decrease of muscle strength, balance, and gait abilities bring about physical inactivity in the elderly. Virtual reality (VR) training has been used successfully to rehabilitate functional balance and mobility in elderly subjects. This study was aimed at determining the effect of VR-based exercise programs by using a video game on the muscle strength, balance, and gait abilities in the elderly. 48 old people were randomly divided into two groups; VR-group (men: 11, women: 14, age: 68.42yrs) and control group (men: 10, women: 13, age: 67.58yrs). VR-group performed an exercise program twice a week for 8 weeks and control group had no intervention. The VR-based exercise program was composed of warm up(10 mins), VR-program(40 mins), and cool down(10mins). It was performed by playstation eyetoy play that provided visual and auditory feedback as well as movements of the upper and lower extremities. Muscle strengths of the knee and ankle were measured using manual muscle tester. Static balance was estimated using computerized posturography. Dynamic balance was measured by Timed up and go test (TUG), Functional reach test (FRT). 10m walk test and 6-min walk test were used to assess gait abilities. After the completion of the VR-exercise program, muscle strength, balance, and gait abilities were improved significantly (p<0.05). In conclusion, the VR-based exercise program showed improvement on the muscle strength, balance, and gait ability in the elderly. This exercise program is both effective and interesting for this age group.

본 논문에서는 유·아동의 독서활동을 돕고자 기존에 있는 동화책과 가상현실 기술을 결합한 몰입형 동화 콘텐츠를 제안한다. VR 환경은 3D 입체 환경을 통한 중다감각적 상호작용을 가능하게 하여 학습자로부터 동기를 유발시킨다. 프로그램이 시작되면 컨트롤러가 활성화되며 동화보기, 미니게임 등 동화에 직접적으로 참여하여 즐길 수 있는 콘텐츠로, 향후 유·아동의 교육적인 면에서도 더욱 효과적일 것으로 기대된다.

As the technology of virtual reality has recently developed, virtual reality treatment programs for game addiction and alcoholism are being developed. The purpose of this study is to present a model of developmental process of virtual reality based cognitive behavior therapy program for trauma intervention in multicultural adolescents. The development of virtual reality program of cognitive behavior therapy consists of three stages. In the first step, In the first stage, the trauma characteristics including the main emotions and the expression problem due to the trauma experienced by the multicultural youth should be grasped. In the second stage, the contents of the development process and scope of the scenario for the cognitive behavior therapy for trauma should be presented. In the final stage 3, the study will examine the feasibility of implementing the scenario contents in the virtual reality program. Through this process, the intervention program development model that can lead the positive change of the multicultural youth was presented.
