In this paper, we describe a haptic jacket and wheel as a haptic interface to enhance VR game realism. Building upon the VR game system using this devices, our haptic interface technique allows the user to intuitive interact on game contents, and then to sense the game event properties such as walking, attacking, driving and fire in a natural way. In addition, we extended the initial haptic model to support haptic decoration and dynamic interactions due to the added game event in a real time display. An application example presented here is a VR Dino-Attack game. This game supports interactions among dynamic and our intuitive haptic interface. Modeling physic interactions involves precise collision detection, real-time force computation, and high control-loop bandwidth.

Objectives : This study was to investigate the effects on using Virtual reality exercise program($Wii-Fit^{TM}$) for dynamic balance and walking ability in patients with stroke. Methods : The 22 subjects were randomly selected from the patients of the S hospital who met the study conditions. They were divided into a $Wii-Fit^{TM}$ balance game group of 12 patients and a conventional physical therapy group of 10 patients. The $Wii-Fit^{TM}$ balance game group received $Wii-Fit^{TM}$ balance game group general physiotherapy for 5 days a weeks, 30 minutes a day, for a 4 weeks and the conventional physical therapy group received general physiotherapy for the same period. The subjects were measured and compared for Brunel balance assessment, functional gait assessment, 6 minute walk test, GAITRite system before and after the program. Results : The experimental group tend to improve more than control group in shifting the weight to the affected side(p=0.040) and tap test(p<0.001). The experimental group tend to improve more than control group in FGA(p=0.016). The experimental group improved significantly more than control group in 6MWT(p=0.008). The experimental group improved significantly more than control group in gait speed, cadence, stride length. Conclusions : Virtual Reality program($Wii-Fit^{TM}$) with conventional physical therapy shows the benefits on dynamic balance and gait parameters in patients with stroke.

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.

A graphic simulator can be a useful tool for planning gaits or dynamic behaviors to a walking pet robot. Microsoft describes robotics developer studio (MSRDS) as an end-to-end robotics development platform including simulation engine based on dynamics. In this paper, we propose a pet robot simulator (PRS), based on MSRDS, which supports interactively controlled two walking robots connected over network. To be pet robot simulator, modeling a commercial pet robot is performed and gait planning is also implemented. By using concurrency and coordination runtime (CCR) and decentralized software services (DSS) of MSRDS software platform, we connect two robots which are displayed together but controlled separately over network. The two walking pet robots can be simulated interactively by joysticks. It seems to be an internet game for pet robots.

The purpose of this study was investigate the effect of rehabilitation exercise using a home video game(PS2, Sony) on gait ability in the chronic stroke patients. The subjects of this study were 32 patients who underwent stroke for more than 6 months and were assigned to a game-based exercise group (n=16) or a control group (n=16). The Game-based exercise group executed a rehabilitation exercise three times a week during 6 weeks, at the rehabilitation unit. The exercise was performed by PS2 for one hour. Control group maintained their usual life without application of exercise. Outcome measures included gait ability. After the completion of the game-based exercise, 10m walking velocity was improved significantly (p<0.05). Six minute walking distance was increased significantly (p<0.05). These results showed that the rehabilitation exercise using a home video game is effective in the improvement of gait ability in chronic stroke patients. This study suggest that interesting, motivating game-based rehabilitation exercise and effective in recovery of function exercise for chronic stroke patients should be necessary to develop and apply.

The conventional 3D graphic accelerator is mainly focused on high performance in the application area of computer graphic and 3D video game How ever the existing 3D architecture is not suitable for portable devices because of its huge power. So, we analyze the embedded 3D graphics renderer. After the analyzing, to reduce the power, triangle set-up stage and edge walking stage are executed sequentially while scan-line processing stage and span processing stage which control performance of 3D graphic accelerator are executed parallel.

This study surveys children's costumes and games from the 11 Genre paintings by Junkeun Kim in the book "Korean Games(Stewart Culin 1858-1929)". The character of the general dress-costumes, games and the culture of life from the late $19^{th}$ century in genre painting of Junkeun Kim are as follows. The study results on the games are as follow. The boy's games are kite-flying, spinning tops, playing shuttlecock with the feet, blindman's buff, yut("Four-Stick Game"). Girl's games are seesaw with board, blindman's buff, marbles. Combined games are mount shoulder, sledge, tightrope walking for men with boy. The strengthen one's body type were seesaw with board, tightrope walking, the compete score type were playing shuttlecock with the feet, marbles and the multi complex type were yut("Four-Stick Game"), kite-flying. Through genre painting in the $19^{th}$ century we know a boy's 'Jeogori 'and 'Ba-ji' were similar to a modern man's and boy's 'Hanbok' with a traditional method of wearing. We believe that the originality of a traditional costume was an unchangeable characteristic. Girl's 'Jeogori' and 'Chi-ma' changed in length and width, and method of wearing; however, the basic shape did not change. The analysis for artist's genre painting which was ordered by a foreigner and the late of $19^{th}$ century's children's costume and game of life culture is useful to match the counters and show how to wear a modern Korean costume used to understand the 'Hanbok' and establish a costume of life.

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.
