Path-finding, one of the traditional Game A.I. problems, becomes an important issue to make games more realistic. Due to the limited resources in the computer system, path-finding systems sometimes produce a simplified and unrealistic path. The most relent researches have been focused on the path-finding avoiding only static obstacles. Various moving obstacles are however deployed in real games, a method avoiding those obstacles and producing a smooth path is necessary. In this paper, navigation mesh is used to represent 3D space and its topological characteristics are used for path-finding. Intellectual repulser and attractor are also used to avoid moving obstacles and to find an optimal path. We have evaluated the path produced by the method proposed in this paper and verified its usability in real game.

The purpose of this paper is to make a game design to overcome traditional prevention system. Cases such as recent cockroach floodings in Seoul, which shows difficulties on understanding the appearance pattern of cockroaches and limitations of the quarantine systems are increasing frequently theses days. In particular public sewer systems which is essential for urban development, face problems due to urban sprawl. In order to solve the problem this study proposes a game design building collective intelligence through citizen participation on cockroach prevention problems.

In this paper, we propose a serious game which aims to draw the interest of rehabilitants and increase their locomotive ability with an infrared ray(IR) pen interface. The proposed game focuses on providing easy-to-manipulate cognitive rehabilitation environments. In order to achieve the goal, we devised new game interface composed of a Wiimote controller and a IR pen. Moreover, SVM(support vector machine) algorithm was employed for gesture recognition. The proposed game can be successfully utilized not only for rehabilitants but also for aged persons in preventing dementia and promoting their health.

Outdoor ads such as billboards, banners or posters frequently appears in street maps of FPS games. In this paper, we propose a method for the automatic placement of outdoor advertising in the city area of FPS games. Outdoor ads are from real world products or enterprises and they are managed in a server computer. If the ads data are updated, the advertisements are automatically placed again without modifying source codes. When placing ads, we utilize the real world location of the game player regarding commercial spheres of ads and service types of real world shops. We evaluate priority scores for the available ads based on the collected real world properties and higher priority ads are preferentially placed on the map. The proposed ad placement method makes the game players feel affinity for the placed ads and also it increases the advertising effect.

This study was conducted with preliminary to develop the game contents for designing of sexual violence prevention serious game for school teachers. It is proposed to use of sexual violence prevention serious game with the analysis of the audience and a new approach. For this purpose, Gordon method and Service Blueprint method were applied in design thinking. The results from analyzing the audiences were to reflect the components of corresponding with the goal of the serious game, and interest and motivation for continuing education. Also, it was proposed to give the certificate of education participation to teachers attended in the serious game in-service education.

1인칭 슈팅 게임(FPS) 장르는 오래 전부터 우리 게이머들의 사랑을 받아 왔다. 특히 2016년에는 오버워치가 그리고 2017년에는 아직 정식 출시도 하지 않은 배틀그라운드가 게임 시장에서 돌풍을 일으켜 현재 PC방 점유율에서 2, 3위를 기록하고 있다. 같은 FPS 라도 실은 우리 게이머에게 가장 익숙한 밀리터리 형 FPS에 비해 오버워치와 배틀그라운드는 서로 다른 형식을 갖고 있으며 이에 따라 전투의 방식과 게임의 목표, 무기 및 스킬의 활용도에서 여러 가지 차별성을 보이고 있다. 이에 본 논문은 전통적 밀리터리 형 게임으로 10년 역사를 가진 아바(A.V.A.) 온라인 게임을 선정하고 이것과 오버워치, 배틀그라운드 3자 간 전투 방식과 무기, 스킬 등의 차이를 비교 분석하여 성공적인 FPS 게임 흥행의 이유를 밝혀 보고자 하였다.

모바일 게임 산업의 발달로 많은 사용자들이 게임을 이용하면서, 그들의 만족감을 사용리뷰를 통해 드러낸다. 실제로 각 리뷰의 범주가 모두 다르지만 현재 구글 플레이 앱스토어(Google Play App Store)의 게임 리뷰 범주는 3가지로 매우 제한적이다. 따라서 본 연구에서는 빠르고 정확한 고객의 요구를 필요로 하는 게임 소프트웨어의 특성을 고려하여 게임 리뷰를 입력했을 때, 게임의 운영 및 시스템에 맞도록 리뷰의 카테고리를 세분화하고 만족도를 분석하는 시스템을 개발한다. 제안 시스템은 인공신경망 모델인 CNN을 평점을 기반으로 훈련시켜 리뷰에 대한 만족도를 도출한다. 또한 Word2Vec을 이용해 단어들 간의 유사도를 구하고, 이를 활용한 단어 배열을 이용하여 가장 스코어가 높은 카테고리로 배정한다. 본 논문은 제안한 리뷰 만족도 및 카테고리 분류 시스템이 실제 효과적으로 리뷰를 보다 의미 있는 정보로써 제공할 수 있음을 보인다.

Recently, various methods have been studied and developed to develop the local cultural contents industry. This research has produced a mobile AR augmented reality game that anyone can easily access by developing contents that can be enjoyed with new tourists. It aims to spread 10 million tourists to surrounding tourist attractions by developing a new storytelling-based AR game using the symbol of Jeonju, which is the birthplace of the Joseon Dynasty, and promote economic value-added activities in nearby stores. GPS technology and AR marker-based action augmented reality games will be newly established as cultural contents based on new regional scenarios. Augmented reality games that combine visual resources are increasing values of local brands by playing games at Jeonju tourist attractions.

Recently many studies has been conducted for interactive game to contents immersion through visual stimuli. Among them, Multi-Plane Image tech is suitable for projecting video in wide views, but it is difficult to perform calibration and mapping tasks for viewing separately. In this paper, we developed a calibration mapping applies to the field archery game space in the form of CAVE. As a result, we maintained the resolution confirmed the space through the video without distortion and expect to be applicable to the fields requiring presence, such as training contents.

Despite the widespread use of digital games as a means of promoting physical activity, little is known about the factors that affect active video gaming. Based on the ecological model of health behavior, this study examined how personal, environmental, and social factors would influence active video gaming and general physical activity. The results showed that while all three factors significantly influence general physical activity, social factor is the only factor that affects active video gaming. The finding highlights the importance of social factors in predicting the use of active video games.
