Among visual communications methods through new media, the typography becomes a key role in information transfer areas with the development of motion graphics. Recently, the researches on stereoscopic image productions have been carried out actively to increase the reality of created images, and the various new approaches for the production of stereoscopic images have been investigated. However, it is obvious that the researches using motion typography have not been studied sufficiently. Thus in this study, the stereoscopic images for moving typography are suggested and produced by using three experimental studies -- the experiments using text movement, camera movement, and finally, editing and composition. In the experiments, from the stereoscopic motion typography produced by our proposed methods, the various visual effects have been obtained, and the visual communication with high reality has been achieved.

This study aimed to maximize the effectiveness of motionbeat rhythm exercise on obese women and its applicability in all fields of sports. In addition, this study aimed to propose a plan to promote continuous exercise for people to incorporate as a means to improve healthy lifestyle. The results showed several effects of EEG on health promoting behaviors. Electroencephalogram (Alpha Power) of the left prefrontal cortex showed to have a significant effect on health promotion activities, with respect to stress management, in the motion beat rhythm exercise group. Considering all research findings, we found that the 8-week motion beat exercise can be used as an appropriate and effective social sport program for overweight women as it brings forth positive changes in the prefrontal cortex that maximizes the pleasantness of and interest in health promotion activities relating to stress management. Moreover, we suggest that it can be a method to create an environment for overweight people to continuously participate in exercises by providing results from fun and relaxingactivities, rather than just creating simple physical effects.

In this study, we examined the evaluation of virtual Reality (VR) according to the use of motion platform. We recorded electrogastrogram, skin conductance, blood volume, skin temperature, heart rate, and the frequency of eyeblink before, during, after virtual navigation in 33 subjects. We used simulator sickness questionnaire, presence questionnaire , and self-report to evaluate cybersickness and presence in VR system. All subjects experienced VR two times in Motion platform condition and non-Motion platform condition at two-week intervals. Presence score of motion platform condition was greater than non-motion platform condition. The frequency and severity of cybersickness were significantly reduced in motion platform condition than non-motion platform condition. These results suggest that the use of motion platform that synchronizes visual presentation provides higher presence and reduces cybersickness.

모션 데이터들을 그래프로 저장하고 이를 모션합성에 이용하는 기존의 연구들은, 모든 모션 프레임간 연결비용계산으로 인하여 그래프 생성에 많은 시간이 걸린다는 단점이 있다. 본 논문에서는 이런 단점을 보완하여 빠르고 효과적으로 그래프를 생성하는 방법을 제시한다. 우선, PCA를 이용하여 모션들을 2차원에 투영시키고, 2차원 상의 간단한 거리계산으로 전이에지가 존재할 가능성이 큰 프레임 쌍들을 찾아낸다. 다음으로, 이런 프레임 쌍에 대해서만 연결비용을 계산하여 그래프를 생성한다. 따라서, 모든 프레임에 대한 비용계산에 비해 본 논문에서 제안한 방법은 효율적으로 그래프를 생성하게 된다.

This paper investigates effective methods for implementing motion matching, which is actively used in real-time motion generation applications. The success of motion matching heavily hinges on its simple definition of a feature vector, yet this very definition can introduce significant variance in the outcomes. Our research focuses on identifying the optimal combination of feature vectors that effectively generates desired trajectories in locomotion generation. To this end, we experimented with a range of feature vector combinations and performed an in-depth error analysis to evaluate the results.

Web-based Promotion of companies have several advantages: They can publicize the brand image in various ways; they enable consumers to learn the information of products in the round with interests; they can stretch out their marketing targets to the whole world. In order to make an effective delivery of their information in such promotion websites, interaction with their consumers is an important factor, for which understanding Interactive Storytelling is essential. The purpose of this thesis is to study Interactive Storytelling which enables us to have effective interaction with consumers in making promotion websites of companies. For this, this thesis analyzes examples of Interact Storytelling focused on it have story promotion websites on the basis of the five steps for internet marketing promotions: attraction of visitors, attraction of interests and participations, acquisition of the information of customers, grasp of the needs of customers, and an offer of values classified by customers.

최근 3D 애니메이션 , 영화 특수효과 그리고 게임제작시 모션 캡처 시스템(Motion Capture System)을 통하여 실제 인간의 동작 및 표정을 수치적으로 측정해내어 이를 실제 애니메이션에 직접 사용함으로써 막대한 작업시간 및 인력 드리고 자본을 획기적으로 줄이고 있다. 그러나 기존의 모션 캡처 시스템은 고속 카메라를 이용함으로써 가격이 고가이고 움직임 추적에서도 여러 가지 문제점을 가지고 있다. 본 논문에서는 일반 저가의 카메라와 신경회로망 및 영상처리를 이용하여 얼굴 애니메이션용 모션 캡처 시스템에 적용할 수 있는 경제적이고 효율적인 얼굴 움직임 추적 기법을 제안한다.

The purpose of this research is to investigate how purchase cycle of a product and bundle frame influence consumers' responses to the bundle promotion. In order to test hypotheses of this study, we conducted an experimental study that was a 2(Purchase cyle: Long vs. Short) X 2(Bundle frame: 1+1 vs. Buy2 and 50% off) between-subjects design. The reseults of this study showed the interaction effects of purchase cycle of product and bundle frame on perceived level of discount and product attitude. Based on the results, we provide theoretical implcations to extent the existing research regarding bundling promotion. Moreover, the results of this study suggest some practical implications and a new aspect about bunle promotions.

In this paper, we propose an approach for extracting and filtering block motion vectors using an adaptive weight function. We first extract motion vectors from a sequence of images by using size-varibale block matching and then process them by adaptive robust estimation to filter out outliers (motion vectors out of concern). The proposed adaptive robust estimation defines a continuous sigmoid weight function. It then adaptively tunes the sigmoid function to its hard-limit as the residual errors between the model and input data are decreased, so that we can effectively separate non-outliers (motion vectors of concern) from outliers with the finally tuned hard-limit of the weight function. The experimental results show that the suggested approach is very effective in filtering block motion vectors.
