모션캡처기술은 이미 많은 애니메이션과 게임에서 보편화되어 사용되고 있다. 하지만, 이런 좋은 기술을 뒤로 한 채 아직도 많은 애니메이터들이 직접 애니메이션을 하고 있다. 모션캡처 기술비용과 제작시간 때문이기도 하지만 사람과 상이한 체형을 가진 3D 캐릭터에 사람의 모션을 적용하기엔 어색한 부분이 많기 때문이다. 또한, 캐릭터의 특징을 부각시키거나 왜곡시키는 등의 과장의 표현은 불가능하다. 캐릭터의 생명은 그 캐릭터가 가진 성격과 체형에서, 그 캐릭터만의 자연스런 움직임을 표현하는데 있다. 기획과 의도에 따른 특성들을 과장하여 표현하되 인간의 동작에 익숙해 있는 우리 눈에 어색함으로 비춰지지 않도록 해주어야 비로소 생명력이 있는 캐릭터를 만들 수 있다. 다양한 모양의 캐릭터는 서로 다른 무게중심을 가졌고 이를 고려하지 않고 애니메이션 했을 때 여러 가지 문제점이 생긴다. 이러한 문제점은 캐릭터가 자연스럽지 못하게 보이는 가장 큰 원인 중 하나다. 본 논문은 게임과 애니메이션 등에서의 3D 캐릭터가 더욱 생생하고 현실적으로 보이도록 돕는데 그 목적이 있다. 그 중, 중요한 요소인 무게중심에 대한 이해와 함께 활용방법에 대한 연구에 목적을 둔다. 캐릭터의 자연스러운 움직임을 위해 무게중심은 반드시 고려해야 할 문제이고 캐릭터의 특성 및 성격 표현에도 중요한 영향을 미친다. 애니메이터들에게 무게중심에 대한 중요성을 알리고 새로운 접근방법을 제시하는 것을 본 논문의 가치로 삼는다.

As a smallest unit of the game story, quest needs to be analyzed in terms of structure in order to study quest storytelling. This thesis introduces structuralist theory of narrative function of folk-tale by Propp to determine the structure of the quest. Propp proposed immutable elements of the characters as 31 kinds of Folk-tale functions. I analyzed assigning quests in MMORPG. As a result, 13 essential functions of the Quest, and 5 add-ons were drawn and the order among functions was figured out. Most quests in MMORPG followed the order of the essential functions and optional add-ons and showed a repeating pattern. The essential and optional functions and its order can be utilized to arrange appropriate element for quest storytelling and to strengthen and lead the various ways of the quest storytelling.

The effects of two different types of haptic feedback(one-hand versus two-hand haptic feedback) on interactivity and body ownership were investigated in the virtual reality setting through an experiment. Using within-subject design, participants performed the task of hitting and destroying a ball-shaped object in virtual reality for both, one-hand and two-hand haptic feedback conditions. The results showed that participants tended to report a higher level of interactivity when using two-hand haptic feedback, whereas there was no difference between the two conditions in a sense of body ownership.

In this research, we investigated the effect of robot programming education on adaption for school life of student with learning disabilities focusing on learned helplessness and the quantity of spontaneous communication. The participant of this study was the student supported with LD really in 4th grade elementary school. Results of the study present that learned helplessness was declined, the quantity of spontaneous communication was increased throughout robot programming education. Based on results, these finding suggested ways to practice the application of strengths-based instruction, intervention utilizing gamification for school life of student with learning disabilities in educational setting.

A lot of research has been done on image recognition technique for planar images and the performance has also been improved. However, it is difficult to recognize objects in spherical panoramic images or images in special form which are given in various environments because of the spherical distortion given in different form from the planar case. In this paper, we show that the neural network recognition approach can be used for object recognition in spherical image and suggest a method of using cubemap transform in order to increase recognition accuracy in spherical image.

In this study, we propose a reliable command placement recognition algorithm using tangible commands blocks developed for our coding puzzle platform, and present its performance measurement results on an Augmented Reality testbed environment. As a result, it can recognize up to 30 tangible blocks simultaneously and their placements within 5 seconds reliably. It is successfully ported to an existing coding puzzle mobile app and can operate an IoT attached robot via bluetooth connected mobile app.

AI-based smart factory technologies are only increase short-term productivity. To solve this problem, collaborative intelligence combines human teamwork, creativity, AI speed, and accuracy to actively compensate for each other's shortcomings. However, current automation equipmens require high safety measures due to the high disaster intensity in the event of an accident. In this paper, we design and implement a factory safety control system that uses a depth camera to implement workers and facilities in the virtual world and to determine the safety of workers through simulation.

The ratio of roles, involving characters created by 2D or 3D Graphic Technology, has risen within games, recent animations, movies and the educational sector. However, the "monster character" appears mainly in "Shanghai Ching" and Greek and Roman mythology. To receive worldwide accolade, it is time that we should use our games, movies and animations to present the history and spirit of Korea. I researched Korean myths so as to understand the characteristics a "Korean monster" would need to portray. This also allowed me to visualise the monster and realize the necessary manufacturing processes involved.

This study examines the access index to the development of immersive contents suitable for elementary school users. The findings of this study can be used as a correct development guide for companies participating in the production of virtual reality sports room contents, by providing users with an effective content experience of education and physical exercise based on the immersive content of sports, physical education, and convergence learning linked with various sensor technologies. As for the research method, this study selected content developed based on the standardization guide of the supporting institution. Through research using expert advice, interviews with sports managers, and content experience survey, this study derived a content access standard index of the virtual reality sports room. Finally, the study verified the developed contents through advanced development applying the production standard indicators.

This paper introduces a mobile augmented visualization technology that augments a three-dimensional virtual human body on a mannequin model using two pose(position and rotation) tracking sensors. The conventional camera tracking technology used for augmented visualization has the disadvantage of failing to calculate the camera pose when the camera shakes or moves quickly because it uses the camera image, but using a pose tracking sensor can overcome this disadvantage. Also, even if the position of the mannequin is changed or rotated, augmented visualization is possible using the data of the pose tracking sensor attached to the mannequin, and above all there is no load for camera tracking.
