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.

Web Services allow a user to integrate applications from different platforms and languages. Since mobile applications often run on heterogeneous platforms and conditions, Web Service becomes a popular solution for integrating with server applications. However, because of its verbosity, XML based SOAP messaging gives the possible overhead to the less powerful mobile devices. Based on the mobile client's behavior that it usually exchanges messages with Web Service continuously in a session, we design the Handheld Flexible Representation architecture. Our proposed architecture consists of three main components: optimizing message representation by using a data format language (Simple_DFDL), streaming communication channel to reduce latency and the Context-store to store context information of a session as well as redundant parts of the messages. In this paper, we focus on the Context-store and describe the architecture with the Context-store for improving the performance of mobile Web Service messaging. We verify our approach by conducting various evaluations and investigate the performance and scalability of the proposed architecture. The empirical results show that we save 40% of transit time between a client and a service by reducing the message size. In contrast to solutions for a single problem such as the compression or binarization, our architecture addresses the problem at a system level. Thus, by using the Context-store, we expect reliable recovery from the fault condition and enhancing interoperability as well as improving the messaging performance.

The attractiveness of e-sports games¹ and the way it is spread has changed in recent years. Instead of conventional approaches, such as advertising campaigns or televised events, spectators are increasingly drawn to online platforms, which offer more opportunities for communication. Besides live streaming services like Twitch. tv, where spectators can watch matches in real-time or via recorded videos, social media platforms like Facebook and Twitter are now adding e-sports related content to their networks [1]. Especially the combination of live streams on Twitch, Twitter, and Facebook opens many possibilities regarding how information is shared. This might be an efficient way of spreading attractiveness among female audiences. This paper focuses on the attractiveness of e-sports events in general for females. It has been hypothesized that there are certain factors that influence this attractiveness. Studying past research papers and online resources, three factors were identified: The players' behavior and charisma, the impact of social media as well as videogames themselves. It is found that females are attracted to e-sport games because they allow them to engage more in the game compared to other videogames. This is because there are no time constraints that require players to accomplish certain tasks within a specific time frame. As such, female gamers can choose how much effort they want to put into the game depending on their personal preferences.

WebRTC는 웹과 모바일과 같이 여러 플랫폼에서 세계 최고 수준의 실시간 커뮤니케이션으로 빠르게 성장했다. WebRTC의 현재 기술은 peer와 시그널링 서버에서 사용자가 요청한 많은 양의 큰 스트리밍을 효율적으로 처리하지 못한다. 따라서, 본 논문에서는 동적로드 밸런싱 알고리즘을 사용하여, 데이터 흐름 전달을 제공함으로써 문제를 처리하는 작업을 수행한다. 또한, 사용자가 요청하는 소스를 분석하고 이러한 스트리밍 요청을 로드 밸런싱 구성 요소에 전달한다. 구체적으로 구성 요소는 요청된 리소스와 사용가능한 리소스의 양을 응답 서버에서 결정한 후 스트리밍 데이터를 요청하는 사용자에게 병렬 또는 교대로 전달한다. 이와 같은 방법을 검증하기 위해 네트워크 시뮬레이션 도구 OPNET을 사용하여 로드 밸런싱 알고리즘을 시연 후 우분투 서버에 적용하여 구현한다. 또한 실험을 통해 도출된 결과와 WebRTC의 구현을 비교하여 제안함으로써 기존 방법보다 효율적이고 동적으로 수행되는 지를 보여준다.
