In aspect of HCI(Human Computer Interaction) gameplay is the procedure to solve the problem that gamers encounter in order to generate or discover a new rule to achieve gamers' goal. The goal of this research is to investigate the structure and understand the gameplay in aspect of affordance from ecological psychology rather than the traditional problem solving theory. This research selects App. game based on smart phone. Expert gamers participated in this experiment. We record all gameplay using audio and video device. We conducted protocol analysis as qualitative method based on the verbal report and action protocol during game playing. As result, gameplay based on affordance includes selection and relation. We found that subjects selected one thing at once with attention. Moreover, we found that there were two behaviors : exploratory action and performatory action. We believe that exploration, action, and transformation for affordance appear. The result of this research imply to suggest design guideline for game design methodology when designers develop game.

In aspect of HCI(Human Computer Interaction) gameplay is the procedure to solve the problem that gamers encounter in order to generate or discover a new rule to achieve gamers' goal. The goal of this research is to investigate the structure and understand the gameplay in aspect of affordance from ecological psychology rather than the traditional problem solving theory. This research selects 'World of Warcraft' as MMORPG(Massively Multiplayer Online Role Playing Game). Five expert gamers participated in this experiment. We record all gameplay using audio and video device. We conducted protocol analysis as qualitative method based on the verbal report and action protocol during game playing. As result, gameplay based on affordance includes selection and relation. We found that subjects selected one thing at once with attention. Moreover, we found that there were two behaviors : exploratory action and performatory action. We believe that learning, utilization, and transformation for affordance appear. The result of this research imply to suggest design guideline for game design methodology when designers develop game.

The market size of online games has been rapidly growing as well as the behaviors of online gaming users have been changed. Online games are different from the traditional video games, because they permit players to interact each other during playing games. Today online gaming is a part of everyday life and social interaction has an impact on online gaming behaviors. Social interaction does not only have a positive impact on online game behaviors, but it also has a negative impact on them such as excessive online game usage. Previous research has a limitation to consider social interaction as a comprehensive concept. In order to fill the gap, we explore the factors of social interaction influencing on excessive online game usage. After reviewing previous literature, this study chooses three factors of social interaction such as escaping loneliness, expanding online social bridging capital, and reinforcing offline social bonding capital. The findings show that all of three factors of social interaction positively affect the excessive online game usage.

Video games, recognized as the "ninth art," carry not only entertainment functions but also the significant responsibility of disseminating ideas and culture. Increasingly, game developers are integrating specific cultural elements into their games, aiming to foster cultural heritage and emotional resonance. This study explores the modern transformation of traditional artistic concepts in the digital gaming field, starting from the Chinese painting theory of 'Woyou'. By examining game examples, the study analyzes the forms of expression of 'Woyou' in virtual landscape spaces and how player identity influences the 'Woyou' experience. The findings suggest that digital games offer new forms of traditional aesthetic wisdom and that Chinese traditional painting theory can gain modern interpretation in the context of digital game design. This provides theoretical support for optimizing game visual design and promotes the expansive development of traditional art concepts in the new media era.

무선망과 인터넷 초고속화와 함께 비디오 스트리밍, 모바일 방송, IPTV 등 통방융합 환경에서의 비디오를 중심으로 한 멀티미디어 콘텐츠 서비스가 보편화되고 있다. 이러한, 이종의 접속망과 다양한 성능의 단말이 혼재하는 융합 콘텐츠 소비환경에서 스마트폰, Tablet PC, IPTV 등 다양한 단말기에서 비디오, 음악, 게임, 데이터 등의 콘텐츠를 끊김 없이 이용할 수 있는 서비스를 일반적으로 N-Screen 서비스라고 한다. 이렇게 단말간의 이동성을 제공하기 위해서는 다양한 플랫폼 형태에 따른 N-Screen 서비스 표준화가 필요하다. 또한, 다양한 스마트 스크린간의 끊김 없는 서비스 이용이 가능한 송수신 기술 및 네트워크 자원을 활용하는 서비스들과 인터넷 기반의 서비스들 간의 상호 연계를 위한 기술들의 표준화가 계속 진행되어야 한다. 본고에서는 이러한 차세대 네트워크 환경에서 N-Screen을 위한 플랫폼과 플랫폼 형태에 따른 N-Screen 서비스 분류에 대해 살펴본다.

Interactive games allow users to obtain embodied experience using the bodies as controllers. The same is true in interactive media arts where users engage in active participation. In contrast to video games, physical body feedback is desired and such practice can be found in robotic arts. I suggest that interactive media arts and interactive games should share common foundations. In this context, I introduce and explain an interactive robotic art work implemented. This work is a musical instrument that employs a robot which travels sitting on two strings in response to audience positions. In results, the robot modulates the vibrations of the strings by causing the effective lengths of the strings changed. The robot uses an economic multi-cell proximity sensor in order to track the audience. In the interaction, phenomenological tension could take place in the performative narrative space. In this paper, I discuss this interactive robotic work in the context of interactive games with a few examples.

Gaming on demand(GOD) makes people enjoy games by encoding and transmitting game screen at a server side, and decoding the video at a client side. In this paper, we propose a fast game video encoder for multiple users over network with low-powered devices. In the proposed system, the computational complexity of game encoders is reduced by using scene descriptors, which consists of an object motion vector, global motion, and scene change. With additional information from game engines, the proposed encoder does not need to perform various complexity processes such as motion estimation and ratedistortion optimization. The motion estimation and rate-distortion optimization skipped by scene descriptors. We found that the proposed method improved 192 % in terms of FPS, compared with x264 software. With partial assembly code, we also improved coding speed by 86 % in terms of FPS. We found that the proposed fast encoder could encode over 60 FPS for real-time GOD applications.

This research examined the effects of user experience in driving simulation game between using general monitor and 3D virtual reality device, Oculus Rift DK2. We compared the difference of user experience such as presence, flow and arousal by gaming environment. We also tested the effects of virtual reality on driving attitude, emotional pleasure and satisfaction. 100 beginner drivers with a driver's license participated in the experiment of two modes of gaming environment. As a result, all the three user experiences were proved to be significantly higher in VR game play than general monitor game. Also driving attitude, emotional pleasure and satisfaction showed a significant difference in virtual reality. This study makes a theoretical and practical contribution to the application of the next virtual reality game with a special function.

This paper proposes a game controller that provides user motion input and tactile feedback display, in addition to the traditional button-type input. The device utilizes both an accelerometer and an infrared camera in order to estimate 3D position and to recognize user motion. The information from the accelerometer and the camera are integrated for better performance. Various tactile sensations are presented using a voice-coil type vibrator. We apply the proposed controller to a motion-based game and validate its usability.
