Wii의 기본 컨트롤러인 위 리모트(Wii Remote)는 모션센서(Motion Sensor)를 내장하고 있어 컨트롤러 사용자의 움직임을 3차원 좌표로 인식한다. 또한, 블루투스(Bluetooth)를 통해 컨트롤러의 확장이 가능하여 PC에서 마우스처럼 다른 응용프로그램을 제어하는데 사용할 수 있다. 본 연구에서는 모션센서와 블루투스 기능을 이용하여 위 리모트를 쥐고 있는 사용자가 화면에 가르키고 있는 좌표 값에 대한 정보를 받아 화면에 나타내는 드로잉을 구현하였다.

Background: Many studies have reported positive results of the various mirror training and virtual reality games in improving dynamic standing balance and posture adjustment in chronic stroke patients. However, no systematic study has been conducted to compare the effects of virtual reality games and the mirror balance training. Objects: The purpose of this study was to compare the effectiveness of Wii balance games and Mirror Self-Balancing Exercises in improving proprioception of knee joint and standing balance of people with chronic stroke. Methods: Twenty patients with chronic stroke volunteered for this study. The subjects were randomly divided into a Wii balance games group and a Mirror Self-Balancing Exercises group with 10 patients in each group. Each training was performed for 30 mins a day for 4 days. In addition to the balance training, 30 mins neuro-developmental-treatment based routine physical therapy was given to both groups. Proprioception was measured using two continuous passive motion devices, and static balance was measured using a Wii balance board. Dynamic balance assessment tools included the Berg Balance Scale, Dynamic Gait Index, and Timed Up-and-Go test. Results: All measured variables before and after the experimental results showed a significant improvement in both groups (p<.05). Only the improvement of the affected knee proprioception appeared to be significantly greater in the Wii balance game group (p<.05). However, other variables did not differ between the groups (p>.05). Conclusion: The findings suggest that both Wii balance games and Mirror Self-Balancing Exercises may be helpful for improving the proprioception of knee joint and the balance of patients with chronic stroke.

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.

Purpose: This study evaluated the feasibility of using Nintendo Wii games for improving cognition, balance, function in patients with dementia. Methods: A total 30 dementia patients were randomly assigned into the experimental group(n=15) and control group(n=15). All subjects performed a general therapeutic exercise, and 30-minute sessions of the table tennis and fencing game of Nintendo Wii were conducted with experimental group 3 times a week for 8 weeks. The intervention effects were measured by using MMSE-K, BBS, and FIM. The results were analyzed by using repeated measure ANOVA. Results: The MMSE-K and BBS scores showed significant differences. A significant interaction was observed between the experimental group and the control group in MMSE-K. The final MMSE-K and BBS scores for the experimental group were significantly higher than those for the control group. However, there was no difference in the FIM scores. Conclusion: We suggest that Nintendo Wii games are effective in cognㅇition and balance improvement in dementia patients. Future research on a variety of programs in needed.

Objective: This study aimed to evaluate and identify variables for the standing balance of elderly subjects with different balancing abilities by using Kinect and Wii Balance Board. Method: The Berg Balance Scale (BBS) test was performed in 40 elderly subjects aged ${\geq}65years$ who can perform daily activities. The participants were divided into two groups, the healthy seniors (n = 20, BBS score ${\geq}52$) and the seniors with balancing problems (n = 20, BBS score < 52). Each group performed two standing tests (eyes open and eyes close) with two devices (Kinect and Wii Balance Board). The root mean square (RMS), mean distance (MDIST), range of distance (ROD), mean velocity, and 95% ellipse area were calculated from the measured data. Results: Among the calculated variables, RMS, MDIST, and ROD in the mediolateral direction showed significant differences between the two groups and a negative correlation with BBS scores. Conclusion: The results of the present study show that simple standing balance of the elderly can be measured with Kinect and Wii Balance Board, which are low-cost, easy to carry, and easy to use, by using the selected variables.

The objective of this study was to develop a system for handwriting recognition in three dimensions (3D) to authenticate users. While previous studies have used a stylus pen for two-dimensional input on a tablet, this study uses the Wii Remote controller because it can capture 3D human motion and could therefore be more effective means of recognition. The information obtained from a Wii Remote controller included x and y coordinates, acceleration (x, y, z), angular velocity (pitch, yaw, roll), twelve input buttons, and time. The proposed system calculates distances using six features extracted after preprocessing the data. In an experiment where 15 subjects wrote "AIZU" 10 times, we obtained a 94.8% identification rate using a combination of writing velocity, the peak value of pitch, and the peak value of yaw. This suggests that this system holds promise for handwriting-based authentication in the future.

사람과 로봇간 인터페이스 연구가 활발히 진행되어감에 따라 원격으로 로봇을 조종하고 그 로봇을 통해 환경 정보를 제공받는 텔레프레전스 시스템에 관심이 증가하고 있다. 로봇이 움직임 따라 자연스러운 텔레프레전스 서비스를 제공하기 위해서는 사용자 행동인식이 매우 중요하다. 이전에 제안되었던 텔레프레전스의 사용자의 이동 인식시스템은 개발이 어려우며 많은 비용이 요구되고 사용자와 로봇간의 상호작용에 많은 한계를 보여왔다. 본논문에서는 닌텐도의 게임기 WII의 적외선 리모콘을 이용하여 사용자의 이동 및 시선을 파악하고 그 정보를 바탕으로 원거리의 로봇(Sony의 AIBO)을 움직여 사용자가 원하는 정보를 HMD를 통해 수신할 수 있는 시스템을 제안한다.
