Recently, Many 3D augmented reality games that provide strengthened immersive have appeared in the 3D game environment. In this article, we describe a barehanded interaction method based on human hand gestures for augmented reality games. First, feature points are extracted from input video streams. Point features are tracked and motion of moving objects are computed. The shape of the motion trajectories are used to determine whether the motion is intended gestures. A long smooth trajectory toward one of virtual objects or menus is classified as an intended gesture and the corresponding action is invoked. To prove the validity of the proposed method, we implemented two simple augmented reality applications: a gesture-based music player and a virtual basketball game. In the music player, several menu icons are displayed on the top of the screen and an user can activate a menu by hand gestures. In the virtual basketball game, a virtual ball is bouncing in a virtual cube space and the real video stream is shown in the background. An user can hit the virtual ball with his hand gestures. From the experiments for three untrained users, it is shown that the accuracy of menu activation according to the intended gestures is 94% for normal speed gestures and 84% for fast and abrupt gestures.

As the prevalence of mobile platforms, expanding digital content production and also increasing interest about the serious game. However, existing educational serious games are short of application of educational function and lower effectiveness that not linked with off-line education. In this paper, we developed an educational serious game 'Rice-Mimi Adventure' for children based Tablet PC. The Games are designed five steps by four elements that storytelling, playing, music and cooking. Specially, players interaction between characters should be increase their own concentration and interest. For the effectiveness verification that linked education of on/off-line, experiment to 126 students of 3,4th grade in Choenan. A result shows positive data that on/off-line linked education using Tablet PC and effectiveness of game contents applied design factors. For this work, we should find effective class and teaching method using digital contents in off-line education for children.

The game is in progress according to the game story with the text, graphic, animation, motion picture, music, etc. Also the result of the game varies depending on the strategy and tactics of the player. For the development of the game, this paper describes the task of the game planner, game programmer, and game graphic designer. Game graphic designers are classified into 4 parts such as the art director, original picture designer, 2D designer, and 3D designer. Among these, the 3D designer makes the 3D game characters with the use of 3D tools. This paper presents the method that 3D designers and beginners can develop 3D characters easily and quickly, Also, this paper shows the method for making preparations of SourceModel which includes 150 polygons. The SourceModel is made up of between five life size and eight life size. In addition, Character Primitives Interface is made to use SourceModel in MaxScript. Accordingly 3D designers have the free use of SourceModel and they will be able to save time.

This paper proposed a method which enabled the designing and implementation of a serious game based on AVR microcontroller on a virtual serial port before making the actual circuit by performing simulation, and which made it possible to develop a serious game. The implemented serious game implemented a mole game which can be enjoyed by one person, a love game with which a male gamer and a female gamer can play, and a marathon game in which a gamer can run the marathon while listening to cheerful music and looking at a region he/she wants to visit. The development of a microcontroller device that provides those functions showed that not only does the device make it possible to develop games more easily and conveniently through the implementation of a game using virtual serial communications with a board designed by an ISIS simulator, but also it reduces trials and errors during game development.

Piano is one of the most beloved instruments in the world and is used a lot for children to learn music because it is simple to play. As a result, various products for children, such as toy pianos, were released. However, there is a lack of piano skills for music education, such as how to play the piano or read the score. To solve this problem, in this paper, we propose a game-style educational piano using Arduino. It is expected to capture fun and education at a low price by scoring points by displaying the score on the LCD screen and pressing the keyboard according to the timing of playing the note.

Augmented Reality (AR) technology has rapidly been applied to various application areas including e-learning and e-education. Focusing on the design and development of android tablet application, this study targeted to develop infant music education using AR technology. We used a tablet instead of personal computer because it is more easily accessible and more convenient. Our system allows infant users to play with teaching aids like blocks or puzzles to mimic musical play like game. The user sets the puzzle piece on the playground in front of the tablet and presses the play button. Then, the system extracts a region of interest among the images acquired by internal camera and separates the foreground image from the background image. The block recognition software analyzes, recognizes and shows the result using AR technology. In order to have reasonably working recognition ratio, we did experiments with more than 5,000 frames of actual playing scenarios. We found that the recognition rate can be secured up to 95%, when the threshold values are selected well using various condition parameters.

본 논문에서는 이미 상용화 되어 있는 안드로이드 리듬게임과는 차별화 된 형식의 게임을 제안한다. 이것은 기존의 리듬게임들이 서비스 제공자가 제공하는 제한된 컨텐츠만 이용하는 것에서 탈피하여 사용자가 기존에 가지고 있는 컨텐츠를 이용할 수 있는 장점을 가지고 있다. BMS라는 음원 컨텐츠를 이용한 음원 패키지가 있다. 이것은 10여년전 부터 PC용 리듬게임에 이용되어 오던 컨텐츠인데 이것을 안드로이드 폰의 이동식 저장소에 저장하여 어플리케이션이 이를 이용하는 것이다. 또한 소셜 네트워크 서비스(SNS)인 페이스북에 자신의 성과를 개제하여 이로인한 지인들과의 커뮤니케이션을 취할 수 있다.

The necessary rehabilitation training for patients with disability currently does not match the actual amount of training conducted, which requires interest in rehabilitation treatment, continued investment and infrastructure for rehabilitation contents, while the most common forms of rehabilitation treatment comprises of art, music, and play treatments. In this paper, we provide a game-style rehabilitation program including audio and visual elements through motion detection process on the patient and design a digital game rehabilitation program that allows different level of management for various categories of disabled people.

We look at the initial stage of Meta (previous Facebook)'s new metaverse platform and investigate its platform design in pre-launch and ignition life stage. From the Rocket Model (RM)'s theoretical logic, the results reveal that Meta firstly focuses on investing in key content developers by acquiring virtual reality (VR), video, music content firms and offering production support platform of the augmented reality (AR) content, 'Spark AR' last three years (2019~2021) for attracting high-potential developers and users. In terms of three matching criteria, Meta develops an Artificial Intelligence (AI) powered translation software, partners with Microsoft (MS) for cloud computing and AI, and develops an AI platform for realistic avatar, MyoSuite. In 'connect' function, Meta curates the game concept submitted by game developers, welcomes other game and SNS based metaverse apps, and expands Horizon Worlds (HW) on VR devices to PCs and mobile devices. In 'transact' function, Meta offers 'HW Creator Funding' program for metaverse, launches the first commercialized Meta Avatar Store on Meta's conventional SNS and Messaging apps by inviting all fashion creators to design and sell clothing in this store. Mata also launches an initial test of non-fungible token (NFT) display on Instagram and expands it to Facebook in the US. Lastly, regarding optimization, especially in the face of recent data privacy issues that have adversely affected corporate key performance indicators (KPIs), Meta assures not to collect any new data and to make its privacy policy easier to understand and update its terms of service more user friendly.
