According to whether language symbols are used to solve puzzles, puzzle games can be roughly divided into puzzle games with language symbols and puzzle games without language symbols. Puzzles games with language symbols can be subdivided into dialogue puzzles games and word puzzles games. These different puzzle-solving methods have different characteristics and have different effects on the empathy in the game. In horizontal scrolling games, due to the characteristics of the third-person perspective of horizontal scrolling games, there is always a 'fourth wall' between the player and the controlled character, making it difficult for players to gain a empathy when playing such games .Especially when there is a dialogue between a player-controlled character and an NPC, the sense of distance between the player and the character will be further amplified. As one of the most common game types in side-scrolling games, side-scrolling puzzle games can be divided into language symbols-based puzzle game and non-language symbols-based puzzle game according to whether language symbols are used to solve puzzles, and then promote the development of the game plot. We combine the characteristics of horizontal scrolling games, and analyze the influence of language symbols on empathy in puzzle-solving games by summarizing the game characteristics of two different puzzle-solving methods. The results show that in horizontal scrolling puzzle games, solving puzzles without using language symbols can better expand the player's sense of plot substitution.

The character is one of most important interest-element in role playing game genres since it shows the individuality. In general cases, game players allocate points to talent clauses that they choose. However, it is not easy to provide the suitable character-growing to players in generic system since the cases are too simple and based on just humans choices. In this paper, we propose the character growing system based on the player type inference module. Growth morphology is determined by player's behavior or type. The determination is based on petri-net. Our experimental results and analysis show that our proposed approach is suitable for character-growing system.

Game artificial intelligence is usually used to provide intelligent and adjusted game environment for user. Previously, it was used for Non-player character(NPC) playing a role of a company or an enemy through collecting and analyzing a user's behaviour. However, it was just mimicking the user's behavior. This paper introduces a method to change game environment by analyzing a user's game behavior. Game behavior data has been used to understand user's game preference. Also, the user's preference was used to provide more active game environment by reflecting decision of geographical features, items and distribution of NPC. For experiment of the suggested method, we utilized a real 2D action game and confirmed the game environment which changing properly according to the user's game play.

The purpose of the study was to analyze kinetic factors required to the three-point jump shot of the basketball games through 3-D analysis and ground reaction force(GRF) analysis. Six university male players participated in this study. The results of the study were showed that (1) resultant velocity in the center of mass(COM) was $0.84{\pm}0.27\;m/s$ since a player didn't shot a ball in the highest peak and shot ball at the moment of going up forward and vertical movement. Therefore, it is necessary to find a proper timing to shot a ball; (2) the angular velocity was largely increased in upper arm and fore arm out of the upper-limb segments and the hands had the largest angular velocity since the body is in a fixed situation and angular speed is rapidly increased by the wrist' snap with the rapid movement of upper arm and forearm at the time of release a ball; (3) it is judged that a player can shot a ball at the accurate and high release point when the player collects power vertically to the maximum by keeping GRF to the right and the rear in a proper way and by keeping the body's balance so that a large power may not be dispersed.

In this paper, a fast implementation of JPEG is discussed and its application to multimedia service is presented for mobile wireless internet. A fast JPEG player is developed based on several fast algorithms for mobile handset. In the color transformation, RCT is adopted instead of ICT for JPEG source. For the most time-consuming DCT part, the binDCT can reduce the decoding time. In upsampling and RGB conversion, the transformation from YCbCr to RGB 16 bit is made at one time. In some parts, assembly language is applied for high-speed. Also, an implementation of multimedia in mobile handset is described using MJPEG (Motion JPEG) and QCELP(Qualcomm Code Excited Linear Prediction Coding). MJPEG and QCELP are used for video and sound, which are synchronized in handset. For the play of MJPEG, the decoder is implemented as a S/W upon the MSM 5500 baseband chip using the fast JPEG decoder. For the play of QCELP, the embedded QCELP player in handset is used. The implemented multimedia player has a fast speed preserving the image quality.

Users connect to game server for considerably many hours and perform their roles in MMORPG(Massively Multiplayer Online Role Playing Game), users' immersion degree is very higher than other games, have known affluent contents make users play various roles in game world. However, although contents of games are improved quite much, MMORPG remains still boring game. It is because that the NPC (Non Player Character)' behavior patterns that are the most important elements to make games fun are so simple. So, in this paper we proposed a method to create NPC that react in player's inclination by implanting personality and emotion to NPC.

The purpose of this study is to identify how game players experience games artistically. We organized indicator categories related to artistic experiences in games through play report produced in participatory player workshop. Based on this indicator, we embodied the artistic meaning of game experience by performing semantic network analysis. As a result, we verified that games can offer opportunities for players to reflect on themselves and their lives.

The purpose of this study is to analyze how auto-combat function in mobile RPG satisfies player's desires. The auto-combat is classified into two types-complete and partial- by timing of activation and degree of control. With elicited aspects of play, players' desires are examined based on Lacan's Desire Theory. A player employing partial auto-combat desires to master higher stages with perfect or flawless control, and one's 'object petit a' is to be the difficulty of the stages. On the other hand, a player applying the complete auto-combat demands to fully comprehend the rules of the game and to attain the rewards of completed stage to build more competent characters. Once a player acquires the desirable object, one recognizes the illusion of one's achievement and seeks for new objects. In this succession, auto-combat function is utilized as an active action of willingness for fulfilling one's desire.

The feature of digital media's interactivity made the traditional storytelling to be evolved into a new concept of digital storytelling. Unlike films or animations, games' storytelling takes open-ended design method; thus, it is possible to create unlimited number of stones within a game depending upon the decisions of player characters. In this paper, a character-centered game storytelling system of a highly story-based RPG genre will be reviewed, and, it analyzes case studies of how a character with various story values can interact with its background story, virtual game world, and many events in its game storytelling system. Game storytelling structure and game mechanics are related to each other very closely. Therefore, it is possible to control the player's overall movement as the character's story develops according to a predictable structure or situation.

This paper designs and implements a multi-view 3D video player system which is operated faster than existing video player systems. The structure for obtaining the near optimum speed in a multi-processor environment by parallelizing the component modules is proposed to process large volumes of multi-view image data at high speed. In order to use the concurrency of bottleneck, we designed image decoding, synthesis and rendering modules in a pipeline structure. For load balancing, the decoder module is divided into the unit of viewpoint, and the image synthesis module is geometrically divided based on synthesized images. As a result of this experiment, multi-view images were correctly synthesized and the 3D sense could be felt when watching the images on the multi-view autostereoscopic display. The proposed application processing structure could be used to process large volumes of multi-view image data at high speed, using the multi-processors to their maximum capacity.
