In this paper, we propose a system that can perform dumbbell exercise by recognizing the weight of dumbbells without wearing and device. With the development of virtual reality technnology, many studies are being conducted to simulate the pysical feedback of the real world in the virtual world. Accurate motion recognition is important to the elderly for rehabilitation exercises. They cannot lift heavy dumbbells. For rehabilitation exercise, correct body movement according to an appropriate weight must be performed. We use a machine learning algorithm for the accuracy of motion data input in real time. As an experiment, we was test three types of bicep, double, shoulder exercise and verified accuracy of exercise. In addition, we made a virtual gym game to actually apply these exercise in virtual reality.

This paper presents an approach to exercise that utilizes motion capture through the Rokoko Smart Suit. With the emergence of Covid-19, physical fitness levels have declined due to restrictions on in-person fitness classes and gym closures. To maintain physical activity, many individuals have turned to mobile applications and streaming videos. However, home workouts often lack the motivation and experience found in gyms, classes, or community centers, particularly with the presence of coaches and instructors. Additionally, instructors find it challenging to convey precise postures to their online students, and vice versa. To address this issue, the researchers propose the use of a full-body tracking suit like the Rokoko Smart Suit, which enables instructors to present a more realistic approach to physical activity. The Rokoko Smart Suit offers a 3D view of the instructor, eliminating the limitations of camera scope when streaming on platforms like Zoom or MS Teams. This technology enhances the at-home workout experience, and the incorporation of 3D virtual reality features can further elevate the realism of a workout.

In order to establish the effective community village as planned, it is the most important factor in residents' participation at the stage of design process. Especially, community space, which is commonly used by all members, must be designed through consultation process of community members themselves to accommodate the needs of various daily activities. So, in this study, the participation process to design the common community facility is developed and the actual residents' participation workshop was conducted in Baek-Hwa village, which is being built on South Korea. Also, the space of community facilities was designed based on the direct opinions and needs of actual residents obtained by workshop process. The workshop was conducted two times: the first workshop was conducted for the design of common residents' facilities and the second was for trying to utilize the virtual designed space. During the workshop process, it is found that the positive participation of members of village is naturally occurred to design residents' space in the workshop process. As a result, most people want to make the space of gym, library, and dining room in spatial configuration. Among them, the hobby room was highly demanded. There is lots of demand for the joint activities and training program in common activity fields. Also, the prediction of the various occurrence so fun expected situations was requested in the game of creating rules and role-playing. In the conclusion, it was acknowledged the necessity of residents' participation design and the importance of communication between architects and residents for decision-making.
