  • To improve the reality of motion simulator, the method of data-driven motion generation has been introduced to simply record and replay the motion of real vehicles. We can achieve high quality of reality from real samples, but it has no interactions between users and simulations. However, in character animation, user controllable motions are generated by the database made up of motion capture signals and appropriate control algorithms. In this study, as a tool for the interactive data-driven driving simulator, we proposed a new motion generation method. We sample the motion data from a real vehicle, transform the data into the appropriate data structure(motion block), and store a series of them into a database. While simulation, our system searches and synthesizes optimal motion blocks from database and generates motion stream reflecting current simulation conditions and parameterized user demands. We demonstrate the value of the proposed method through experiments with the integrated motion platform system.

  • 캐릭터가 발전하는 이유 중 사람의 감정을 충족시키려는 욕구는 움직이지 않은 캐릭터에게 반영되어 인터랙티브 캐릭터로 발전되었고 현재 인터랙티브 캐릭터는 사람들의 많은 관심을 받고 있다. 그 중 최근에는 기존의 인터랙티브 캐릭터인 타마고치와 포스트 팻의 장점을 가져온 휴대용 게임기기인 NDSL의 게임 '닌텐독스'가 등장했다. '닌텐독스'는 터치스크린, 마이크와 같은 체감형 인터페이스를 사용하고 있다. 또한 사람들에게 친근한 강아지라는 캐릭터를 사용하여 사람들이 캐릭터를 애완동물과 비슷하게 느끼고 감정을 교류하게끔 유도하고 있다. 하지만 인터랙티브 캐릭터들이 감정을 표현하기에는 기존의 인공지능으로는 해결할 수 없기 때문에 인공감정을 사용하여 인터랙티브 캐릭터의 감정을 표현하도록 제안한다.

  • 최근 컴퓨터 게임에 등장하는 NPC(Non-player Character)에 각종 인공지능 기법을 적용하는 연구들이 이루어지고 있다. 하지만 대부분의 연구가 플레이어를 상대하는 적대적 입장의 NPC들의 움직임 조절에 초점을 맞추고 있고 아직까지 게임 상에서 등장하는 모든 NPC는 항상 같은 말과 비슷한 행동을 되풀이하는 모습만을 보여주고 있다. 이는 플레이어가 게임을 비현실적으로 느끼게 만들고 결과적으로 게임의 재미를 저하시키는 요소로 작용한다. 플레이어에게 보다 현실적인 게임 환경을 제공하기 위해서는 NPC가 단순히 게임의 배경을 구성하는 오브젝트가 아니라 다양한 대화를 통해 플레이어에게 많은 영향을 주게 하여 게임의 기여도를 높여주어야 한다. 본 논문에서는 이를 위해 게임 속에서 주어지는 퀘스트를 구성하는 NPC, 몬스터, 보상 등의 속성 정보를 온톨로지로 구성하고, 인터넷에 존재하는 게임 커뮤니티에서 퀘스트 질의/응답 게시판의 글을 추출하여, 플레이어의 관련 질의에 응답하는 NPC를 구현하고자 한다. 이를 위해 온톨로지 정보를 이용한 검색 알고리즘을 구현하였고, 시뮬레이션을 통해 NPC가 커뮤니티 게시글(국문/영문) 정보를 이용하여 유저에게 고정되지 않은 다양한 메시지를 전달하면서 동시에 유저의 게임 진행을 도와주는 모습을 확인하였다.

  • In early stages of film or animation production, storyboard is used to visually describe the outline of a story. Drawings or photographs, as well as the texts, are employed for character / item placements and camera pose. However, commercially available storyboard tools are mainly drawing and editing tools, not providing functionality for item placement and camera control. In this paper, an Augmented Reality based storyboard tool is presented, which provides an intuitive and easy-to-use interface for storyboard development. Using the presented tool, non-expert users may compose 30 scenes in his or her real environments through tangible building blocks which are used to fetch corresponding 3D models and their pose.

  • The construction of digital map which is the basis of GIS becomes more important. The digital map is made up of image, numeric, and character data. The development of mapping system which makes the data inputted easily is important. In this paper interactive map¬ping system is introduced, which is currently developed. Also, map data structure is seriously discussed. The points of improvement on this system are considered.

  • The purpose of this paper is to develop simulations that can be used for virtual education in dentistry. This development goal is to allow dental students to learn the necessary surgical techniques at the point of their choice, not going into the operating room, away from time, space, and physical limits. In this paper configuration, the optimization method is applied convergent, and when the operation of the VR contents is performed, the content data is extracted from the interaction analysis formed in the VR engine, and the data is processed by the content algorithm. It also computes events and dental operations generated within the 3D engine programming and generates corresponding events through data processing according to the input signal. The visualization information is output to the HMD using the rendering information. In addition, the operating room environment was constructed by studying lighting and material for actual operating room environment. We applied the ratio of actual space to virtual space and the ratio between character and actual person to create a spatial composition at a similar rate to actual space.

  • Rather than a directing method of existing animations, VR animation needs a different method of direction. Existing animations were displayed on a screen in movie theaters. But using an existing direction method for the 360° perspective in a VR animation makes it difficult for the user's gaze to move in a way the directors have intended. I analyzed 3 VR animations with a theoretical background of Rudolf Arnheim's visual perception theory and Bruce Block's visual factors that bring high attention. In the process of perception of space, focus on the gaze, movement of the gaze, the 'movement' factor was used most often to attract the gaze. An interactive VR animation attracts user's gaze by allowing users to participate in important points of the story. With an analysis of the animation, it proposed a gaze attraction through the movement of the character with an interaction directing method for reducing motion sickness. Also, it proposed intuitively attracting gaze movement by using GUI and attracting user's participation by using an interactive event with an interaction directing method of storytelling comprehension. With two types of directing proposal, we expect it to be utilized as a basic research method for attracting users to be immersed in storytelling while reducing cyber motion sickness, which is a problem in VR animation.

  • In this research, Affective computing game has been developed which reacts with a player's bio-signals. A modified computer mouse will be used to collect bio-signals by GSR, FSR, and infrared thermometer. This modified computer mouse collect human bio-signals in non-intrusive way. The collected data is complementary reflected in 3 level of tension of a player. The player's tension affects on the game and the reaction for NPC will be followed. Then this leads to plot changes individually. To let diverse NPC reaction and interactive story telling, Live 2d and Inkle Script have been used. This research can be alternative method on the game development using Affective computing.

  • The animation should be produced to attract the audience's interests. Its characters will have the intended personalities through the interactions with the audiences, discarding the attributes of the nature. These personalities form the brand identity when they are exposed visually and will be powerful brand assets which lead the animation industry to the high-value added products. The brand identity of the character, the brand assets, can be used for various products in form of licensing and is noted to make an affirmative leverage effect. In this regard, the author has conducted an empirical research on the animation characters from the viewpoint of the brand, adopting, in particular, the Brand Personality Scale (BPS), which is the output of J. Aaker's (1997) study on brand personality defined as the human properties in relation with the brand. In addition, this study determines the correlation among the animation, brand and consumers based on the Sirgy's study (1982) resulting in that the better the brand and the consumer's personality are matched, the more the brand attitude is improved. In consequence, it is found that the animation characters have three personality levels such as refinement/ability, integrity and interests. The consumer's personality is divided into the 'practical ego-image' and the 'ideal ego-image' in the survey, and the survey result shows that the brand personality of the animation character exists between them.
