This Study analyzes dynamic of a puzzle game play by applying entropy law. Entropy is a concept that a quantitative measure of the amount of thermal energy not available to do work in a closed system. And amount of entropy can be measured only if we see the closed system as whole, the field. Puzzle game is also closed system. When player moves an object in game, it change a relationship among objects in play field. In , through an act of position change, player sustains a play field active. In respect of an entropy, this kind of play is considered as pursue of usability of the energy. In , player piles up objects without empty space. In respect of an entropy, this kind of play is considered as pursue of the order. Likewise, puzzle game play can be considered as simulation of a human's pursue of the order in an entropy increasing physical world. And this pursue is a driving force of puzzle game play.

This study is intended to compare and analyze the figurative characteristics of game characters focusing on the MMO shooting game 'Battle Ground' and the MOVA game 'League of Legends,' which currently have the largest number of users in Korea, in order to assess how much effect the figurative shape of game characters has on the immersion of players. As a result, the shape of characters from MOVA or MMORPG games with storytelling as an important factor was revealed to have a greater effect on the immersion degree of players than that of the characters from fast-paced shooting games. In particular, it was found that in games where the level of each character is raised as items are added, the height of most characters is the same as their own eight or nine heads, which is longer than ordinary people.

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.

Due to the problem of matching between virtual world space and real-world space, the reality of augmented reality content is rather low. There are many reasons for this result, firstly virtual object is rendered without considering relation between real-world space and virtual world space. Secondly, virtual objects rely too much on the marker to reduce reality. We propose two schemes to improve the reality of augmented reality, one is people occlusion, the other is to reduce the dependence of virtual objects on the marker.

The A* algorithm is a well-known pathfinding algorithm. However, if the information about obstacles is not exploited, the algorithm may collide with obstacles or lead into swamp areas unnecessarily. In this paper, we propose new heuristic functions using the information of obstacles to avoid them or swamp areas. It takes time to process the information of obstacles before starting pathfinding, but it may not cause any problems most of cases because it is not processed in real time. We showed that the proposed methods could reduce the search space effectively through experiments. Furthermore, we showed that heuristic functions using obstacle information could reduce the search space effectively without processing obstacle information at all.

In state-of-the-art games, characters can move in a goal-directed manner so that they can move to the goal position without colliding obstacles. Many path-finding methods have been proposed and implemented for these characters and most of them use the A* search algorithm. When .the map is represented with a regular grid of squares or a navigation mesh, it often takes a long time for the A* to search the state space because the number of cells used In the grid or the mesh increases for higher resolution. Moreover the A* search on the grid often causes a zigzag effect, which is not optimal and realistic. In this paper we propose to use visibility graphs to improve the search time by reducing the search space and to find the optimal path. We also propose a method of taking into account the size of moving characters in the phase of planning to prevent them from colliding with obstacles as they move. Simulation results show that the proposed method performs better than the grid-based A* algorithm in terms of the search time and space and that the resulting paths are more realistic.

Given a state, it is essential to for the finite state model analysis (such as model checking) to decide whether or not the state is reachable. W a site of the model is small, the whole state space is to be explored exhaustively. However, it is very difficult or even impossible if a size of the model is large. In this case, the model can be reduced into a smaller one via abstraction which does not allow e false positive error. this paper, we devise such an abstraction and apply it to the Nemorize game solving. As a result, unsolved game due to the state explosion problem is solved with the proposed abstraction.

A dynamic graph is suitable for representing and managing dynamic changable obstacles or terrain information in 2D/3D games such as RPG and Strategy Simulation Games. We propose a dynamic hierarchical graph model with fixed level to perform a quick A* path finding. We divide a graph into subgraphs by using space classification and space model, and construct a hierarchical graph. And then we perform a quick path fading on the graph by using our dynamic graph operators. With our experiments we show that this graph model has efficient properties for finding path in a dynamic game environment.

Communication as a process of interpreting signs has always existed in people's life. In post-information society, the communication between a person and a technological system through the specific sign-attaching process becomes widespread. Moreover, it somehow replaces usual communication between people. One of the means of communication in the digital space are video games. They not only play an important role in communication processes, but also are a special case of sign-creating and interpreting. The purpose of the article is to examine video games as a space of sign-based communication between a person and a game as a specific digital system. With the help of general scientific and hermeneutic methodology, the analysis of video games as a post-information society phenomenon which people communicate to has been conducted. The process of semiosis as attaching special meanings to signs has been traced in both manipulating in-game objects and characters and understanding rules of an in-game world.

The background fort this study is related to the concept of modern time and space which has been extended from physical space to virtual space in the present times witnessing the advent of the Fourth Industrial Revolution. Based on visual tactility and illusion in virtual reality, we intended to present the possibility of the interactions as realistic as the interactions occurring in reality. Regarding the scope of this study, we analyzed the relationship between illusion in game space and immersion in interactions based on the games used frequently among current virtual reality contents. The results of the study showed that the interactions in virtual reality occurred within the space converging the time and space and that the illusion of digital images had realistic position of reality without original. Research which investigates the interaction in virtual space and media projection method for real space and virtual space will provide useful basis for promoting technological development based on novel methods differentiated from existing image grammar and for identifying the content utilization methods.
