Natural user interface (NUI) is used for the natural motion interface without using a specific device or tool like a mouse, keyboards, and pens. Recently, as non-contact sensor-based interaction technologies for recognizing human motion, gestures, voice, and gaze have been actively studied, an environment has been prepared that can provide more diverse contents based on various interaction methods compared to existing methods. However, as the number of sensors device is rapidly increasing, the system using a lot of sensors can suffer from a lack of computational resources. To address this problem, we proposed a real-time multi-device control system for natural interactive platform. In the proposed system, we classified two types of devices as the HC devices such as high-end commercial sensor and the LC devices such astraditional monitoring sensor with low-cost. we adopt each device manager to control efficiently. we demonstrate a proposed system works properly with user behavior such as gestures, motions, gazes, and voices.

The ideologie of modern society as per something to phenomenology problem is to show various different looks. The community space is spring from Greek and Roman of community place by agora and forum is make a active communicate to interpersonally. Subject to centrically In the context, this paper is study on the Sustainable development for community space about interactive space. and focusing is Response to human of interact in each other intelligent space. And this paper suggestion is composition method of community space in technology advanced, Interactive interface form for human, sustainable to community space direction elements. First, I'll rearrange the distinctive features of modern society through references of various scholars. This is to understand how interactivity affects the whole society and what is the importance of this interactive wave. Second, I'll analyze several trends of modern community space and figure the change of methodology of design based on the advancement of design technology. This is to understand the interactive relation of the subjects. Third, I'll seek how community space design has changed in modern society and under which process design is made. This is to clarify the fact that the portion of interaction will increase in future design according to the intervention of equipment, which is one of the objects of interaction space.

We introduce an interactive image cartooning system based on personal subjectivity. To effectively tune various parameters needed to adjust image style, our system uses interactive genetic algorithm. By selecting several pre-stylized image samples using simple user interface, the user can easily achieve the desired result without having any signal-processing knowledge. Our system reduces the parameter tuning time drastically compared to the conventional system, which involves manual parameter setting.

5G-based HMD technology grew rapidly in the context of the environment change of convergence technology media and mobile networks in the fourth industrial era. It has also grown into a core technology that transforms our digital visual system. However, there is no research or system that can understand and verify radical visual system changes. Therefore, it is necessary to have an engineering understanding and verification of the diffusion of HMD media imaging devices. Beyond the distinction between virtual and real, research is urgently needed on the new three-dimensional interface of the 21st century through viewer participation. For this reason, research on the algorithm structure of interactive video media using L-System is an essential process and will be a guide to understanding the virtual reality interactive environment.

This paper presents the preliminary study of an interactive rehabilitation support system for both dementia patients and their caregivers, the goal of which is to improve the quality of life(QOL) of the patients suffering from dementia through virtual interaction. To achieve the virtual interaction, three kinds of recognition modules for speech, facial image and pen-mouse gesture are studied. The results of both practical tests and questionnaire surveys show that the proposed system had to be further improved, especially in both speech recognition and user interface for real-world applications. The surveys also revealed that the pen-mouse gesture recognition, as one of possible interactive aids, show us a probability to support weakness of speech recognition.

There will be many large displays in common public places, and we expect that these displays will give users many convenient interactive services. However, due to the physical size, typical mouse and keyboard are not suitable for user interactions on large displays. Recently there are many studies investigating on new interaction techniques and input devices developed for user interactions in a large display. In this paper, we describe the iTILE framework designed to help develop the interactive tiled display applications. Then we describe two iTILE applications using the tape switch interface and the tangible interface with infrared camera and markers.

The web technology related with internet at present is changed into the 3D interactive environment form one sided communication of simple contents. In this paper, a high quality interactive Web3D Contents was realized by using the TurnTool, a authoring tool. This paper suggests the method that can easily and quickly realize the Web3D manual which is more realistic md capable of interaction with user. This method makes up for the weak points in the existing Web3D tool system. Therefore we can realize the contents that able to easily interact through minimizing file size md omitting procedure of additional EAI(External Authoring Interface) by using the Java Script.

Multi-touch display system has recently attracted world wide attention due to easy accessibility to the various interactive media without any specialized equipments. Especially, Microsoft Sphere(R) shows a considerable promise in treating non-fiat multi-touch display. The distinctive feature of the system is a stable multi-touch interaction on a spherical display. To extend the possibility of the interactions to the more various display surfaces, this paper propose a multi-touch interaction system in the circumstance of the irregular convex surface. The proposed method can be used efficiently in various tangible interface, for example, the interactive diorama system at the exhibition or the tangible arcade game.

This paper suggests a collision techniques for a higher reality in augmented reality by processing collision between a real object obtained through video frame input and a marker-based virtual object or a virtual object from Opengl. Augmented reality system is providing the visual information containing a virtual object added to the real environment and interactive interface between objects and between user and objects becomes a more concerning interest. But the collision problem is essential to the interactive interface and has to be solved first. Therefore, the proposed system suggests a solution for it to increase the realism and the immersion by validating the collision among a marker-based object, a virtual object from Opengl, and a real object obtained through web camera, that is, video frame.

This paper proposes a dynamic gesture recognition algorithm using SVM(Support Vector Machine) which is suitable for multi-dimension classification. First of all, the proposed algorithm locates the beginning and end of the gestures on the video frames at the Kinect camera, spots meaningful gesture frames, and normalizes the number of frames. Then, for gesture recognition, the algorithm extracts gesture features using body parts' positions and relations among the parts based on the human model from the normalized frames. C-SVM for each dynamic gesture is trained using training data which consists of positive data and negative data. The final gesture is chosen with the largest value of C-SVM values. The proposed gesture recognition algorithm can be applied to the interactive storybook as gesture interface.
