In this note, we propose a game system to fairly and transparently control and update game variables using blockchain. As an example, we present an Ethereum-based maze escape game, being the first blockchain-based maze game and the first attempt to control game level through blockchain. In this system, the level function computes maze level reflecting the amount of maze walls purchased/sold by users. Using blockchain for game management saves human and economic resources and prevents unfair practice of game developers unilaterally manipulating game level or item enhancement rate.

This paper describes the development of an optimal 3D maze path game as web-based game contents. Client user using web can access and run java applet program with download of java byte code with the independence of hardware system. The optimal 3D maze path game developed in this paper consists of random maze path generation module, selected path input module, weighted optimal path search module, and path comparison module. It enhances the cognition faculty of game users with the comparison of the maze path searched by optimal path search algorithm and the selected maze path by game users.

In this paper, we design and implement a mobile game based on Kinect sensor. This game is a motion recognition maze game based on Kinect sensor using XNA Game Studio. The game consists of three stages. Each maze has different size and clear time limit. A player can move to the next stage only if the player finds the exit within a limited time. However, if the exit is not found within the time limit, the game ends. In addition, two kinds of mini games are included in the game. The first game is a fruit catch game using motion recognition tracking of the Kinect sensor, and player have to pick up a certain number of randomly falling fruits. If a player acquire a certain number of fruits at this time, the movement speed of the player is increased. However, if a player takes a skeleton that appears randomly, the movement speed will decrease. The second game is a Quiz game using the speech recognition function of the Kinect sensor, and a question from random genres of common sense, nonsense, ancient creature, capital, constellation, etc. are issued. If a player correctly answers more than 7 of 10 questions, the player gets useful items to use in finding the maze. This item is a navigator fairy that helps the player to escape the forest.

With the analysis result about previous curative effect researchs, It has been reported that game play therapy is effective for enhancing social intelligence of handicappted children who have ADHD, tic disorder, communication disorder, or autism. This study was designed to develop a digilog game play therapy contents that was combined analog and digital. We infer that this contents is effective game play therapy not only for ordinary people but also for dementia old man, or intellectual disorder man. Also We are going to develop a new digilog play game system for preventing children's smartphone addiction.

Robots, games and life applications have been developed while computer areas are developed. Moreover, various applications have been utilized for various users including the early childhood. Recently, smart phones have been dramatically used by various users including early childhood. Many applications need to find a path from a starting point to destinations. For example, without using real maps, users can find the direct paths for the destinations in realtime. Specifically, path exploration in game programs is so important to have accurate results. Nowadays, with these techniques, diverse applications for educations of early childhood have been developed. To deal with the functions, necessity of efficient path search programs with high accuracy becomes much higher. In this paper, we design and develop a friendly maze program for early childhood based on a path searching algorithm. Basically, the path of lineal distance from a starting location to destination is considered. Moreover, weight values are calculated by considering heuristic weighted h(x). In our approach, A* algorithm searches the path considering weight values. Moreover, we utilize depth first search approach instead of breadth first search in order to reduce the search space. so it is proper to use A* algorithm in finding efficient paths although it is not optimized paths.

The purpose of this study was to review the literatures on designing and developing the CAI program and to develop the middle school students’CAI program for tutorial and instructional game. For these purposes, the learning and instructional theories and the developing phases and strategies for the program were reviewed to design the CAI program. And then the developing unit was selected and the CAI types and the developing direction were set according to the analysis of the CAI programs and related literatures on home economics teaching, The four phases-analysis, design, development, and formative evaluation-were carried out in this study. The results of this study are as following: 1. The CAI porgram was developed on health and food life units. The program contains 12 classes on health and food life in two floppy diskettes. It consisted of total 9,000 lines and 76 frame and takes two hours to study this program. This program could be used in educational computers an could be utilized for unit learing tutorial. It was composed of three parts-unit learning, finding maze, and finding food. In the unit learning part, the learning contents in health and food life units were structured and presented. In finding maze and food part, the basic and the applied problems were presented with game. The characteristics of this program were as followings: (1)This program was able to bring learners’motivation due to the strategies of tutorial and instructional game and they can interestingly learn the program for themselves. (2) The learner could practive the learning contents repeatedly and unit learning while playing the gaming, (3) The learner himself can review and supplement the learning contents without teacher’s help. (4) This program was developed to unit learning on health and food life, on the other hand so far many CAI programs for home economics teaching were developed for studying separate learning units. 2. To effectively utilize this program, the guide book for the student and the teacher was developed. It contained method of using the program, introduction of the program, review of the program, the program objectives, the learning contents, and the keys to progress the program.

윈도우 시스템은 90년대 이후로 지속적으로 사용되어진 개인용 컴퓨터의 운영체제로 그래픽 사용자 인터페이스와 멀티프로세싱 기능 등을 제공한다. 최근 배포되어지는 8.1 버전은 기존의 윈도우 시스템과 비교하여 다양한 특징을 가지고 있지만 윈도우 스토어는 네트워크를 이용하여 설치할 수 있는 다양한 응용 프로그램을 제공한다. 그러나 현재 윈도우 스토어에는 게임을 위한 응용 프로그램은 거의 제공되지 않고 있다. 이 논문에서는 사용자가 간편하게 설치하여 실행시킬 수 있는 미로탈출 앱을 설계한다. 제안한 앱은 저용량으로 윈도우 스토어에서 다운로드해서 사용자가 직관적으로 미로탈출 게임을 할 수 있도록 한다. 이를 위하여 HTML5와 자바스크립트를 이용하여 개발한다.

We have been interested in solving escapee-chaser game. In this game, with avoiding chaser, the escapee must escape from given male. The winning strategies of the escapee are driving the chaser to an intended place and closely evading from chaser by using some walls. According to our experience, some stages of the game are too difficult to solve manually. So we take the model checking method to get a solution of the game. Because the model checking with breadth fist search manner exhaustively searches the all state space of the game, the solution using model checking is best solution, shortest path. Fortunately, during the process of finding solution path, the state space explosion problem didn't occur, and the results of the game solving was applied to embedded system, Lego Mindstorm. Two agents, escapee and chaser, were implemented into robots and several experiments conformed the correctness of our solution.

본 논문에서는 퀄컴의 Vuforia 엔진을 이용한 증강현실 미로 찾기 어플리케이션을 제안하고 구현하였다. Vuforia 엔진은 증강 현실 엔진 중 비교적 최근에 만들어져 다양한 마커를 활용할 수 있으며 속도, 마커 인식 면에서 다른 AR 엔진에 비해 뛰어나다. 본 논문에서는 Vuforia 엔진에 기반한 미로 찾기 앱을 설계하고 구현한다. 제안한 방법에서는 스마트폰으로 이미지 마커를 인식한 후, 스마트폰 화면에 3D 캐릭터와 미로를 출력해주도록 한다. 또한 가속도 센서를 이용하여 사용자가 직접 스마트폰을 기울여 캐릭터를 목적지까지 이동시키는 미로 찾기 게임 어플리케이션을 구현하였다.
