  • 립모션(Leap Motion)은 가상현실 환경의 상호작용 장치로 각광받는 기기이다. 이에 따라 가상현실 출력장치인 HMD에 립모션을 부착해 사용하는 콘텐츠가 늘고 있다. 하지만, 립모션이 HMD상의 부착된 위치가 매번 다르기 때문에, 립모션의 손가락 감지범위와 HMD의 출력 범위가 서로 다르다는 문제점이 있다. 이를 해결하기 위해 본 논문에서는 번들 조정 알고리즘을 이용해 HMD와 립모션의 상대위치를 추정하는 기법을 제안한다. 제안하는 기법을 통해 HMD와 립모션을 부착해 이용하는 콘텐츠에 전처리기로 활용할 수 있을 전망이다.

  • While many games have been published that are used with input-devices such as a mouse and keyboard, the number of games that can recognize the behavior of a human utilizing devices such as Kinect and Wii has increased. In this paper, we present the development of a baseball game that utilizes a Leap Motion Controller. A Leap Motion Controller recognizes accurately the movement of a user's fingers. Our implemented game consists of characters, a background and animation. It is a moving animated game in which the users play a game in point of view of a third person. The major feature of our game is that the game players can enjoy the game using a Leap Motion Controller.

  • In this study, the robot arm control system was implemented that is operated by human hands, which can be used in environments that are inaccessible to humans. This function has to be sent to the robot's arms after extracting coordinates of human hands. Through mapping and bluetooth communication we use a leap motion sensor with infrared light and Image recognition sensor.

  • With recent rapid development of computer capabilities, various technologies that can facilitate the interaction between humans and computers are being studied. The paradigm tends to change to NUI using the body such as 3D motion, haptics, and multi-touch with GUI using traditional input devices. Various studies have been conducted on transferring human movements to computers using sensors. In addition to the development of optical sensors that can acquire 3D objects, the range of applications in the industrial, medical, and user interface fields has been expanded. In this paper, I provide a model that can execute other programs through gestures instead of the mouse, which is the default input device, and control Windows based on the lip motion. To propose a model which converges with an Android application and can be controlled by various media and voice instruction functions using voice recognition and buttons through connection with a main client. It is expected that Internet media such as video and music can be controlled not only by a client computer but also by an application at a long distance and that convenient media viewing can be performed through the proposal model.

  • In this paper, we propose a new framework that calculates the user's hand motions using a Leap Motion device, and uses this to practice and analyze arm muscles as well as juggling motions. The proposed method can map the movement of the ball in a virtual environment according to the user's hand motions in real time, and analyze the amount of exercise by visualizing the relaxation and contraction of the muscles. The proposed framework consists of three main parts : 1) It tracks the user's hand position with the Leap Motion device. 2) As with juggling, the action pattern of the user throwing the ball is defined as an event. 3) We propose a parabola-based particle method to map the movement of a juggling shape to a ball based on the user's hand position. As a result, using the our framework, it is possible to play a juggling game in real-time.

  • IT서비스 기술이 융 복합 형태의 모습으로 다양하게 발전하면서 콘텐츠를 사용함에 있어 새로운 방식의 인터페이스들이 나타났다. 본 논문은 기존의 단순한 인터페이스인 키보드와 마우스를 벗어나 사람의 모션을 인식하여 게임, 교육, 음악 등 다양한 분야를 컨트롤할 수 있는 립모션을 활용한 에듀테인먼트 콘텐츠를 제작하였다. 콘텐츠 방식은 학습을 단계별로 진행하고 글자 맞추기, 글씨쓰기 등 게임을 하여 정답을 맞추면 점수를 획득하는 방식이다. 제작한 에듀테인먼트 콘텐츠는 단순한 교육이론 학습이 아닌 학습자가 직접 체감할 수 있어 더욱 학습효과의 극대화가 가능하다.

  • 본 연구는 립모션을 통해 피아노교육을 제공함과 동시에 알맞은 운지법을 제안한다. 기존의 피아노 교육 프로그램은 운지법을 제공하지 않아 피아노를 한 번도 접해보지 못한 사람들은 제대로 된 기초를 배우지 못했다. 따라서 본 논문에서는 알맞은 운지법을 제안하고, 립모션과 컴퓨터가 실행되는 환경 어디에서든 프로그램을 실행 할 수 있도록 하였다.

  • Motion-sensing interface enhances the sense of reality of user experience in virtual reality context. This study analyzes the innovation resistance and adoption structure for Leap Motion, which provides a motion-sensing function, primarily considering the theory of perceived risk. Previous research regarding innovation resistance and adoption mainly addressed the resultant aspects of perceived risk, or the impact of perceived value on the adoption intention. This study synthetically reviews previous studies from a multi-dimensional view considering both resistance- and adoption-perspective. To do so, we identified important antecedents that affect perceived risk and value, and we analyzed the compound dynamics of perceived risk and value towards innovation resistance. As a result, we found that the antecedents included in the existent acceptance models from adoption-perspective can help reduce the level of perceived risk, and that higher perceived value leads to lower innovation resistance. Additionally, trialability can rather foster the perceived risk.

  • This paper proposes a user interface for enhancing immersiveness and usability by combining hologram and haptic device with common Leap Motion. While Leap Motion delivers physical motion of user hand to control virtual environment, it is limited to handle virtual hands on screen and interact with virtual environment in one way. In our system, hologram is coupled with Leap Motion to improve user immersiveness by arranging real and virtual hands in the same place. Moreover, we provide a interaction prototype of sense by designing a haptic device to convey touch sense in virtual environment to user's hand.
