This paper describes the general process of making augmented reality game for real objects without markers. In this paper, point cloud data created by using slam technology is edited using a separate editing tool to optimize performance in mobile environment. Also, in the game execution stage, a lot of load is generated due to the extraction of feature points and the matching of descriptors. In order to reduce this, optical flow is used to track the matched feature points in the previous input image.

Objectives: This study aimed to investigate the effects of a 4-weeks intervention using a monitor-based virtual reality game intervention(VRI) on the cognitive function and activities of daily living of individuals with acute stroke. Methods: For this study, 19 individuals with acute stroke were recruited. To compare the effectiveness of the VRI and the computer based cognitive intervention(CBCI), Each of the two groups were provided different interventions a 30 minutes a day, 5 times per week for 4 weeks, and to measure the effects of the intervention, the TMT A&B, DST, RKMT and K-MBI were performed before and after interventions. Results: Both the VRI and the CBCI were found to have significantly improved the cognitive function and activities of daily living, and the difference in change compared between groups showed that the effectiveness of the VRI was significantly higher. Conclusion: Based on the findings of this study, the monitor-based VRI is anticipated to prove useful as an effective intervention for the cognitive function and activities of daily living of stroke patients. Furthermore, the utility of monitor-based VRI is likely to be high in clinical occupational therapy.

스마트폰의 도입으로 인하여 증강현실이 널리 알려짐에 따라 대중들의 관심은 이에 집중되고 있으며 휴대성으로 인하여 모바일기기에서의 증강현실 연구가 하나의 흐름으로 자리 잡고 있다. 기존의 증강현실과 인공지능이 결합된 연구들은 주로 로봇공학이 많은 비율을 차지하고 있으며 게임에 접목된 연구들은 부족한 실정이다. 또한 인공지능이 적용된 에이전트들의 움직임을 위한 데이터들은 아직까지 사용자가 직접 입력해주거나 이를 인식하는데 마커를 사용하고 있다. 본 논문에서는 마커리스 추적 기술을 사용하여 생성한 데이터를 인공지능부분에서 사용하며 증강현실 기반의 인공지능이 적용된 에이전트를 위한 게임 시스템을 제안한다. 그리고 이를 아이폰 모바일 기기에서 구현하였으며 인식율, 정확도를 측정하여 본 시스템을 검증하였다.

This paper describes the development of a functional game for preventing dementia for the elderly based on virtual reality. The game was developed using the Unity 3D engine to create a fishing spot, a virtual reality space. In consideration of the fact that the object of the game is an elderly person relatively unfamiliar with the virtual reality, the number of operation buttons is minimized and the sense of resistance and fatigue are reduced by an intuitive game configuration. In addition, the game was designed to give people a sense of accomplishment with a score system after the game, and to encourage them to participate in the game Overall, the developed game consists of main, interface, stage, score, TTS, tutorials, and ending credit. Each category stage is divided into three stages and realized in one integrated environment, and VRHMD can be used to games that enhance memory, attention, and judgment.

본 논문에서는 개발한 가상현실 게임의 소개와 적용기술에 대하여 서술하였다. 가상현실(Virtual Reality, VR) 게임은 기존의 게임과는 다른 몰입도와 평면을 넘은 가상의 공간, 활동적인 액션의 이점을 가지고 있고 사람들과 같이 활동적인 플레이를 더하기 위해 다중사용자 환경의 기반을 구현하고, 좀 더 활동적인 다중사용자 환경으로 만들기 위해 서로 경쟁하는 사격게임과 같이 협력하여 플레이해 나가는 디펜스게임을 개발하였다. 개발도구로는 에픽 게임스의 언리얼 엔진4 v4.19.2을 개발엔진으로 활용하였고, HTC Vive의 VR장비와 컨트롤러를 사용하여 다중사용자를 위한 VR 게임 콘텐츠를 개발하였다.

K/DA is a K-pop virtual idol based on the game character. This study analyzed the creation process, characteristics and existential meaning of virtual idols from the perspective of Pataphysics. K/DA is a character with both characteristics of game character and K-pop girl group. Also, virtual character and real idol share the body through motion capture and augmented reality(AR). As a result, K/DA crosses virtual and reality, and at the same time becomes a pataphysical subject that does not belong to either virtual or reality. K/DA is suggested a third zone where digital subjects will be located in the future.

The purpose of this study was to investigate the effects of virtual reality game based training on balance and upper limb function in subacute stroke patients. Thirty patients with subacute stroke were randomly assigned to experimental groups(n=15) and control groups(n=15) applying virtual reality game-based training programs. Intervention is applied three times a week for 6 weeks, 30 minutes for 1 time. In the study group, there was a significant improvement in balance ability, upper extremity function, and trunk impairment scale(p<.05), and the difference between the two groups was significant in the BBS, TUG, TIS(p<.05). Based on these results, the virtual reality game based training program is clinically useful exercise program for subacute stroke patients.

Most current games are composed of simple operations without a user's actual movements. because they are made up of only virtual space. For that reason, many side effects arise on a user's body and mind. The Alternative Reality Game(ARG) is new game genre that has an effect to mitigate side effects caused by activity on a virtual space. This new kind of game genre can be instrumental role in creating a greater social intimacy and a higher tendency to cooperate that potentially reaches beyond the game context. In this paper, we suggest a real implementation of ARG using mobile devices and NFC tags. In addition, a noble editor for creating an ARG and a game launcher based on mobile device are suggested.

The computer game industry has been developed gradually because of development of graphics and communication industry, Games have an important role to peoples in various ages in their leisure life. Game has been changed into various forms with its development. With this movement, it is not only for simple amusement, but starts trying to use them for educational object. It is called Serious Game that intends to particular object and effect. Serious game has the important meaning to get some new useful things through its enjoyment which is the essence of games. Many people in various field have tried many categories of contents. Especially, education stands out among the other fields. Fields related with education have been studied extensively. This paper would suggest mathematics education game based on Augmented Reality. It is a board game for infants and young students. Augmented Reality is used to extend user's experience and multiplicity of the game. We also offer users a tool that helps them to create their own board for their active game participation.

As the world game marcket has been recording weak growth, the development of new gane concept is required to attract the gamer's attention from those who were fed up with the previous game paradigm. Recently, the game which can recognize the player's motions and provide new interaction between the game and user is more popular than ever before. In the games with somesthesia based on Virtual Reality, the sense of the reality is considered the most important factor for drawing immersion from the gamers. In this work, a new type of 3-axis accelerometer based interactive game interface which can effectively recognize the gamer' motion is suggested. Furthermore, various experiments are carried out to verify the effectiveness of the proposed scheme.
