이동통신 단말기의 그래픽 유저 인터페이스 환경은 다양한 요인에 의하여 그 변화를 자극 받고 있다. 한정된 디스플레이 공간 안에서의 다 기능화로 인한 사용성의 문제, 정적이고 지시적인 상황에 익숙한 문자 중심의 세대에서 자율적이고 동적인 영상 중심의 세대로의 사용자 세대의 변화, 합리적 소비 보다는 감성적 만족을 중요하게 여기는 사용자 가치의 변화, 그래픽 디자인 트랜드의 변화, 서비스 컨텐츠의 변화, 기술의 발전 등 이동통신 단말기를 둘러싼 모든 측면에서 변화가 진행되고 있다. 여기에 이동통신 단말기 제조사, 서비스 업체, 컨텐츠 업체, 칩 제조사 등 이동통신 서비스와 관련된 다양한 사업 주체들의 복잡한 이해관계 속에서의 경쟁 또한 이러한 변화를 부추기는 요인의 하나로 볼 수 있다. 본 연구에서는 이러한 변화요인들을 적절히 수렴하여 제공할 수 있는 보다 효과적인 그래픽 유져 인터페이스 디자인 방법을 모색하고자 하였으며, 보다 효율적이고 적극적인 개선을 위해 현재 이동통신 단말기의 GUI 디자인의 주요 디자인 수단인 Bitmap 또는 Vector 그래픽 대신 보다 다양한 시각적 표현 방법을 내재하고 있는 3D 기반의 Motion 그래픽을 활용한 이동통신 단말기의 GUI 디자인 방법을 제안 하고자 한다. 하지만 아직 여러가지 제약 조건들로 인하여 이동통신 단말기 내에서 3D Motion 그래픽의 적용이 완전히 자유롭지 않은 것이 사실이다. 그러나 기술의 발전 속도로 볼 때 머지 않아 3D Motion GUI 제공을 위한 이동통신 단말기의 기술적 환경은 충분히 발전될 것이며, 이에 따라 본 연구와 같이 3D 그래픽이나 Motion 그래픽을 등을 활용한 이동통신 단말기의 사용자 인터페이스 연구의 선행은 매우 필요하다고 볼 수 있다.

Korean Sign Language (KSL) is a communication method for the Deaf in Korea, and hand shape is one of important elements in sign language. In this paper, we developed a KSL hand shape editor to simply compose hand shape and connect it to a database. We can edit hand shape by a graphical user interface (GUI) on 3D virtual reality environment. Hand shape codes are connected to a sign word editor to synthesize sign motion and to decrease total amount of KSL data.

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.

Recently, there are lots of concerning on the integration of robot and virtual reality with the trends of the research of intelligent robot and mined reality. In this paper, a 3D GUI system is proposed based on Internet for remote controlling and monitoring of agent robot working for itself. The proposed system is consists of a manager ordering a new position and displaying the motion of robot, an agent robot moving to the destination according to the indication, a positioning module detecting the current position of robot, and a geographical information module. A user can order the robot agent move to a new position in a virtual space and watch the real images captured from the real sites of the robot. Then, the agent robot moves to the position automatically with avoiding collision by using range finding and a path detection algorithm. We demonstrate the proposed 3D GUI system is supporting a more convenient remote control means far the robots.

NUI(Natural User Interfaces) has been developed through CLI(Command Line Interfaces) and GUI(Graphical User Interfaces). NUI uses many different input modalities, including multi-touch, motion tracking, voice and stylus. In order to adopt NUI to legacy GUI applications, he/she must add device libraries, modify relevant source code and debug it. In this paper, we propose a gesture-based interface model that can be applied without modification of the existing event-based GUI applications and also present the XML schema for the specification of the model proposed. This paper shows a method of using the proposed model through a prototype.

With the development of game technology, the realistic game graphics, interface technology, and various content services with immersion are being required in the content area. NUI has been developed through CLI and GUI. Unlike the conventional methods, it is an interface that could be the intuitive and realistic interface for human as a natural action realized. we propose a boxing simulation game using leap motion of it. Providing a realistic 3D experimental environment through VR headsets game, we also propose a method that can be calculated the scores if the user-controlled interface (fist) could be to punch the target (sandbag) of the internal in accordance with changes of the angle of target impact with the physical characteristics.

This study aims to establish a foundation for autonomous driving on campus and communication of abundant university information in the HCI environment in a VR environment where college freshmen can freely travel around campus facilities. The purpose of this study is to develop a three-dimensional VR-style campus tour system to establish a media environment to provide abundant university information guidance services to freshmen in non-face-to-face situations. This study designed a three-dimensional virtual reality campus tour system to solve the problem of discontinuity in which VR360 filming space does not lead to space like reality, and to solve many problems of expertise in VR technology by constructing an integrated production environment of tour system. We aim to solve the problem of inefficiency, which requires a large amount of momentum in virtual space, by constructing a GUI that utilizes the motion of the field of view focus. The campus environment was designed as a three-dimensional virtual reality using a three-dimensional graphic design. In non-face-to-face situations, college freshmen freely transformed the HMD VR device, smartphone, FPS operation mode of the gyroscope sensor.

Palletizing tasks are necessary to promote efficient storage and shipping of boxed products. These tasks, however, involve some of the most monotonous and physically demanding labor in the factory. Thus, many types of robot palletizing systems have been developed, although many robot motion commands still depend on the teach pendant. That is, the operator inputs the motion command lines one by one. This is very troublesome and, most importantly, the user must know how to type the code. We propose a new GUI(Graphic User Interface) for the palletizing system that is more convenient. To do this, we used the PLP "Fast Algorithm" and 3-D auto-patterning visualization. The 3-D patterning process includes the following steps. First, an operator can identify the results of the task and edit them. Second, the operator passes the position values of objects to a robot simulator. Using those positions, a palletizing operation can be simulated. We chose a widely used industrial model and analyzed the kinematics and dynamics to create a robot simulator. In this paper we propose a 3-D patterning algorithm, 3-D robot-palletizing simulator, and modified trajectory generation algorithm, an "overlapped method" to reduce the computing load.
