In this paper, we present a model of a virtual world that incorporates different time periods, in contrast to current popular virtual worlds like Second Life, to utilize the digital space fully. The construction of a virtual world in which we include historical information in the virtual life simulation utilizing the world map and current space information is proposed. The reason for incorporating time is that the virtual world varies according to the politics, economics, society, and culture of a particular time period, so users are able to play in a distinct virtual world as a resident and make their communities of their own free will. Like the online encyclopedia Wikipedia, the model proposed in this paper is a project designed to be maintained by and expanded through the interactivity of users, but unlike Wikipedia, users of this virtual world will be able to live and interact in a world of their own creation in addition to contributing real information.

Variation of the observer's viewing position is one of the major causes of image space distortion in the stereoscopic display. Especially, a large image distortion, which is caused by different depth direction positions of the observer's two eyes, is made by the observer's rotation movement in relation to the center of the screen. This is different from distortion of horizontal and depth directional movement of the observer. In this paper, we analyzed distortion of the image space due to the observer's rotation movement and showed the corrected result of distortion through simulation in the stereoscopic display. Finally, we showed that the distortion shape of the observer's rotation movement is different from horizontal and depth directional movement of the observer.

Attempts to embody the three-dimensional world into works have continued without distinguishing between the times and the media, and the purpose is to realize an immersive state rather than the reproduction of reality. It was considered that the flat screen, which is the medium that finally faces the viewer in digital media art, hinders complete immersion, and this study investigated and analyzed the cases of works that give a sense of reality of space beyond the limits of the screen. Using the results of the analysis to produce the work, it was found that the presentation of the realistic space and enhancing immersion in the digital media art field should be viewed not only as visual video content on the screen, but also as an installation suitable for the exhibition environment and the resulting space itself.

Extended Reality (XR) is an immersive technology that combines the real and virtual worlds and is being actively researched across various industries. This study proposes a method for utilizing the Meta Quest 3, a head-mounted display (HMD) that provides mixed reality, outdoors for the first time by leveraging the GPS information from a smartphone. Augmented virtual objects are positioned using location information and the orientation. Additionally, by using the features of the Meta Quest 3, virtual objects are made to appear alongside the real world, allowing users to interact with virtual objects through hand gestures. This study aims to link present and past spaces by using location information and photographs on the HMD, providing a novel experience of freely traversing time and space.

Proper education for the space&environment as a medium for the development of a variety of educational programs can be understood as the necessary training for maintaining sustainable society through the sharing of community lives. In addition, education programs of space&environment as a medium will help school teachers and students to understand the meanings and values contained in the living environment by contributing to the increase of creative culture and responsible social consciousness. In this paper, the analysis will be carried out to understand the current situation of education programs of space&environment of inside the school education in progress in Korea. Major parts of the paper will analyze the meaning and value of space&environment education by looking at the contents and activities of diverse training programs of Finland and UK. Finally, this paper will suggest how to activate collaborative school education on the space&environment by the complement of the ongoing problems found in the analysis of domestic case studies.

Contemporary architecture pursues new method of Interpretation of Non-linear space as digital media appears. As various materials and new methods can be used due to developments in science and expansion of thinking, contemporary architectural color developed extensive possibilities. It means not only the change of drawings, method of architectural product and materials but also the change of value system for architectural space. Thus the purpose of this paper is to suggest interpretation of space applied by color structure, and this point of view was based on the three elements of color perception which are light source, reflector, and observer. According to this categorization, architectural color of exterior color, layer color and interaction color are explained via examples of colors recently used on the contemporary architectures. In summary, contemporary architecture can be explained by Non-construction space interpretation for intrinsic complex meanings. Therefore, it can be explained as moving space, collage, by picturesque space, moving blur color and emptiness of color. This pursues various point of views for space interpretation, therefore it can be developed to the identity of strengthening architectures' design concept.

In these days, the smart devices are being developed and used repeatedly. But almost E-learning System did not provide these smart devices environment and user's E-learning space is changing from Single-screen environment to multi-Screen environment. Accordingly we configure smart E-learning space based on multi-screen and integrate the multi-media contents for the Smart E-learning service. We present the synchronization techniques to make the multi-screen environment for smart space with Timed Link and design the Timed Button to relate each Screen which is using multi-media e-learning contents.

Recent advanced interlace technologies allow the user to interact with different spaces such as Virtual Reality (VR), Augmented Reality (AR) and Ubiquitous Computing (UC) spaces. Here, we present a LEGO House application, a collaborative application which involves multi interaction spaces -VR, AR and UC spaces. The LEGO House application is built based on the VARU framework which is designed for enabling the prototyping of a tangible space application. The application is about an interior design. One user is located in the combined AR and UC space and interacts with the AR LEGO house and the physical smart devices. The other users interact with the virtual LEGO house but they share the same environment, the LEGO house. Therefore, they can collaborate together as they are co-located.

Due to the problem of matching between virtual world space and real-world space, the reality of augmented reality content is rather low. There are many reasons for this result, firstly virtual object is rendered without considering relation between real-world space and virtual world space. Secondly, virtual objects rely too much on the marker to reduce reality. We propose two schemes to improve the reality of augmented reality, one is people occlusion, the other is to reduce the dependence of virtual objects on the marker.

In this paper, we propose an indoor-space recognition using DNN and super-pixel. In order to recognize the indoor space from the image, segmentation process is required for dividing an image Super-pixel is performed algorithm which can be divided into appropriate sizes. In order to recognize each segment, features are extracted using a proposed method. Extracted features are learned using DNN, and each segment is recognized using the DNN model. Experimental results show the performance comparison between the proposed method and existing algorithms.
