Sociability is an inherent part of human life and also possesses an important value as a comprehensive ability. While the lack of sociability has been pointed out as a representative problem of game use in general, this paper analyzed studies on the relationship between online video games and social competence. In this field, the view that the relationship in the online game may replace or complement the actual relationship and will potentially hinder the development of sociability currently faces a conflict with the opinion that online video games may not directly have a negative effect on sociability but rather result in a positive outcome by providing a social learning space. In a large scale survey that measured the use of online games, psychological characteristics, and social competence, no distinct relationship between game use and degradation of sociability was observed. Based on this analysis, we suggest that efforts are necessary to break away from the stereotype that online game play may cause a decline in sociability and to improve the validity of related research.

VR(Virtual Reality), which has drawn attention as a major area in ICT, is currently being used in various fields, including medical care, movies and architecture. Although VR technology is used in various fields, contents are mainly developed by creators where needs of users are easily left out of consideration leading to failure in forming a consensus between UI(User Interface) and UX(user experience). To identify the consumer preference and attribute level of VR game content, which is responsible for the largest proportion of VR contents, this study was designed to examine the consumers' preference properties of VR game contents through a Conjoint Analysis and derive the relative importance and weightings of each group. The study collected 166 questionnaires over a total of three months from May to July 2019, 150 of which were completed (90.4%). Statistic analysis was conducted using SPSS Ver. 25.0. The results of the study showed that the genre of the game (42.6%), number of players (24.0%), price for payment (20.3%) and game planning (13.1%) were important attributes in choosing VR games. The optimal mix of attributes was derived with new games, RPGs, multi-play and medium price (22,000 KRW). Before mentioning technology in the expectations of users who use VR game content, which is the most preferred among VR contents, this study recognized the need to have a fun and new experience through VR game content. Therefore, it is expected that this will serve as a reference for consumer behavior of VR game contents and research on VR game contents development.

The objective of this study is to find out how reality game shows, the relatively new television genre, produce a sense of reality and what differences we can find from the reality they produce in compared to that of traditional reality television shows. The researchers anaylized , aired in 2013and 2014 by tvN, with focus on the show's studio setting and characters in the show. During this process, the 'game elements' and 'reality factor' were considered to be the key words. Finally, the reality produces was examined from two aspects: the production and reception. As a result, we found that the reality it produces is more than just a imitation of the real world. It shuttles between the game world and real world, and encourages audiences to recognize the plural realities in our postmodern society. We hope this study stimulates further researches on reality game show genre, which had rarely gained academic attention.

Recently there has been an increasing interest on tangible games in which human motions are recognized rather than the handling of keyboards and mouses. Such games require a motion controller for recognizing the motions of users. In this paper, we analyze the characteristics of values of accelerator sensors which are generated by a user who perform a tennis swing while holding a smartphone with his/her hand, and propose a method for motion recognition based on DWT(Discrete Wavelet Transform). The proposed method enables a smartphone to serve as a motion controller, so that a user can enjoy a tangible tennis game without eliminates a need for buying the device. We developed a tennis game prototype using the proposed method. To our experiment, our method showed a high recognition rate and the usefulness in the game.
