In this paper, we propose a new approach to providing interactive and collaborative lens among multi-users for supporting level-of-detailed views using smartphones in a public display. In order to provide smartphone-based lens capability, the locations of smartphones are effectively detected and tracked using Kinect, which provides RGB data and depth data (RGB-D). In particular, human skeleton information is extracted from the Kinect 3D depth data to calculate the smartphone location more efficiently and correctly with respect to the public display and to support head tracking for easy target selection and adaptive view generation. The suggested interactive and collaborative lens using smartphones not only can explore local spaces of the shared display but also can provide various kinds of activities such as LOD viewing and collaborative interaction. Implementation results are given to show the advantage and effectiveness of the proposed approach.

The purpose of this research is to develop subject of up-to-date scientific technology, according with science museum, and to deviate from the old style, simply-seeing display, and the passive display which simply support narrative styles by one-way action. In addition, for motivating audience to take part in the display, this study is to analyze displaying technique, key marks of an exhibit and then to create the way which science museum should follow in order to plan interactive scenario and display technique. By analysis and consideration of museums, which I took for a sample, this study will work out display scenario, based on interactive concept, and experience display technique. Moreover, this study will suggest alternatives and basis in order to develop display technique of up-to-date science in science museum.

The interactive display is providing various interaction modes to users through various ubiquitous computing technologies. These methods were studied for their interactions, but the limits that it is provided to only single user and the device usability were generated. In this paper, we propose a new type of spatial multi interaction interface that provide the various spatial touch interactive to multi users in the ambient display environment. Therefore, we generate the interaction surface so that a user can interact through the IR-LEDs Array Bar installed in the ceiling of the ambient display environment. At this time, a user can experience the various interactions through the spatial touch in an interaction surface. Consequently, this system offers the interactive display and interface method that the users can interact through natural hand movement without the portable devices.

In this paper, we propose a development methodology of interactive stereoscopic image display system. In our case, we consider a multiple touch recognition technique as the interaction method. That's because we want to guarantee multiple user access and interaction to the content without any restriction. In this case, however, some restrictions are occurred on account of the distance between display and participants. For this reason, this paper propose an invisible interaction surfaces which are generated in the air. This surface is utilized as interaction medium instead of the display wall. We also present an effective way to generate and edit interactive stereoscopic images based on Game Engine.

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.

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.

Tabletop display can take the benefits of the interactive device due to its possible user friendly input and display facilities simultaneously. Using this device, immersive edutainment content is effectively implemented with the convenient interactive interface. So considering this usefulness, tabletop display can be a very efficient device for constructing the edutainment system. In this paper, we describe a digitalized cooking edutainment contents based on the tabletop display interface. Enjoying our contents, we use the intuitive touch gestures for handling a variety of cooking actions. In the education effects such as the immersive strengthening and co-operation, the proposed system is more efficient interface than any other existing system. We implement the contents with the tabletop display and make sure about the efficiency of our proposed system. In the future, we will add more gestures to enhance the applicability of the intuitive interactive interface.
