본 연구는 Laban이 제시한 모션 분석 기법을 이용하여 모션의 긴장도를 측정하는 방법을 제안한다. 이러한 긴장도값을 이용하면 캐릭터 모션과 배경음악간의 자동적 동기화를 위한 기준값으로 사용할 수 있다. Laban의 모션 분석 기법. 즉 LMA는 모션을 Effort라고 명명된 4개의 시공간적 요소로 나누고 각 4개의 Effort마다 2가지 상반된 기준을 제시함으로써 모션을 분석하도록 하였다. 이러한 기준을 양적으로 측정하기 위해 우리는 운동학, 역학에 기초한 수식을 제안하고 이를 통해서 계산된 실제 긴장도 값을 실험데이터에 근거하여 조정하였다. 실험을 통해 제안한 긴장도 측정 결과는 어느 정도 사람의 반응과 비슷한 정도의 순위 판별 능력을 보였다.

In this paper, we propose the method to measure tensions of character motions, using LMA (Laban Movement Analysis). Using tension values, we tan take advantage of them as a standard for synchronization of motion and BGM(Back Ground Music). In LMA, a motion is divided into 4 space-time factors which are called Efforts, and each Effort has two bases opposed to each other. We can analyze the motion by justifying which basis is stronger than the other in each Effort of motion. To measure quantitatively tension values, we propose some equations based on kinematics and dynamics. Then we can measure the tension value by the weighted sum of values calculated from those equations. Each weight can be determined by the optimization process which tries to minimize the difference between the calculated tension value and human's decision. The experimental result shows that the in creasing order of the motion tension value is similar to that of the tension score given by human.

현대 사회에서 인간은 과학의 발달과 환경오염, 복잡한 사회에서의 다양한 인간관계 둥으로 인해 긴장과 불안을 경험하며 자신도 모르게 스트레스를 받으며 살아가고 있다. 긴장과 불안은 스트레스의 요인이 되며 지속적으로 쌓이게 되면 정신적, 신체적 질병을 가져온다. 이러한 스트레스를 해소하기 위한 방법으로는 바이오피드백, 이완요법, 명상, 가벼운 운동 등이 있으며 현재는 멀티테라피가 널리 이용되고 있다. 본 연구에서는 기존의 스트레스 해소방법이 아닌 시각적 요소만을 가지고 제작된 모션그래픽을 활용하여 심리이완을 유도할 수 있는 방법에 관하여 연구하였다. 첫째, 모션그래픽의 구성요소 중 3가지 요소(색, 헝태, 방향)를 조합한 설문 모션그래픽 중 어떤 요소가 가장 심리이완을 유도하는 것인지를 조사하여 분석하였고, 둘째, 3가지 요소(색, 형태, 방향)를 각각 2가지로 나누어 특성을 비교 분석해 보았다. 그 결과 심리이완을 유도하는 모션그래픽은 한색, 원, 수평으로 조합된 모션그래픽으로 문헌 조사와 동일한 결과를 나타났으나, 각 요소별 분석에서는 3가지 요소 중 색과 형태는 동일한 반면, 방향은 수평보다 수직이 심리이완을 유도하는 요소로 분석되었다. 향후 본 연구를 토대로 각 요소에 대한 세부적인 분석이 이루어진다면 심리이완에 있어 모션그래픽의 폭넓은 활용이 기대되어진다.

This paper is to study techniques of a virtual reality to maximize the depth of the users' immersion based on differentiated interactive contents using korean traditional fairy tale. In order to increase more interests in korean traditional fairy tale, we produce a interactive 3D contents and propose a new approach to a system designing applying a virtual realities such as HMD, Leap motion. First, using Korean traditional fairy tale, we generate interactive contents consisting of scenes intensifying user's tensions while interaction of game process. Based on the interactive contents generated, we design scene generation using Oculus HMD, the gaze based input processes and a hand interface using Leap motion, in order to provide a multi dimensional scene transmission and an input process method to intensify the sense of the reality. We will verify through diverse tests whether the proposed virtual reality contents based on a technique of an input process will actually intensify the immersion in the virtual reality or not while minimizing the motion sickness of the users.

Information of video can be percieved as the form of visual rhythm through temporal ordering systems. The shot, the base unit of video analysis, affects audience psychologicaliy with various temporal combination. Here, psychological stress and density of the story can be adjusted by the point of view shot of character. Acordingly the correlation analysis of shot duration and point of view shot can be useful for visual rhythm research. Identity one of the thriller genre works was selected for analyzing. This works produced by Kyle Cooper, a famous person in the opening sequence field. This works produced by Kyle Cooper, a famous person in the opening sequence field.

With increase of internet users, usage frequency of e-mail card is growing up. In addition to advantage of delivering message in real-time, e-mail card contains words, animation and sound. So users can enjoy it's multiple characters. For these reasons, there is a shift in preference from traditional card to e-mail card especially in young age. In character portal sites sewing users with e-mail card it is regarded as useful media for character promotion. After bizarre rabbit 'Mashimaro' wins a great success as Flash animation, Flash card has been treated as an important media in character business. As the study on the aesthetic motive in Flash card, this thesis analyzes what is the meaning existing in characteristic expression of Flash card and proposes that the meaning is related to tension reduction from the viewpoint of entropy principle. We can summarize that contents of animation are based on striving toward simplicity and expressions of animation are based on catabolism. Both lead to pleasure of tension reduction. We can draw conclusion that pleasure of tension reduction becomes one of major factors of the aesthetic motive felt in Flash card.
