The most profound technologies are those that disappear. Silicon-based information technology, in contrast, is far from having become part of the environment. The idea of integrating computers seamlessly into the world at large runs counter to a number of present-day trends. Ubiquitous computing is not just aiming nomad multimedia. Rather, this computing environment lets us free to use computers without thinking and so to focus beyond them on new goals. In that context, Mom is such a fundamental membrane through which humans can interact with the environment. An embodied interaction paradigm, based on Mom, is investigated. Mom, space. sensing/perception, ubiquitous computing, and interactive technology are some of the key ideas to explore.

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.

The purpose of this study is to examine expression characteristics of Koreanity of indoor spaces and food-related elements in Korean restaurants that preserve Korean cultural identity and to acquire basic datas for total design planning that integrates not only spaces but also food-related design elements including food, tableware, table setting and food styling. For these purposes, we selected 18 Korean restaurants showing Koreanity based on related magazines issued during the period from 2000 to 2005 and Internet sites related food. The survey method is to investigate the selected restaurants visited in person, and the intangible and tangible characteristics of their indoor spaces and food-related elements were recorded in detail, photographed and analyzed. The results of study is as follows: First, among intangible elements, the most frequent one in space was formative aesthetic characteristic(60%), and that in food is socio-cultural characteristic(60%). Second, as to Koreanity expression methods through tangible elements, the most frequent method for space was the use of contemporary elements as mains and traditional elements as supplements (11cases) and that in food is compromise between traditional food and contemporary recomposition (16cases). In order to develop competitive Korean restaurants in the global age, we need to create stories based on various intangible elements found in our indigenous culture beyond fixed traditional designs from the past and to produce total designs of food space design and table settings through consistent concepts.

The traditional market has formed for itself through a long time thus has special value of the place. The tangible value of the traditional market is high, however, it became jeopardized to be dismantled since it can not cope with the consumption environment of modern society. Modern industrial society provides an inefficiently and standardized solution to the traditional market by ignoring the identity of place only by the value the traditional market in the law of large distribution industry. This study aims to define the placeness of Namdaemun traditional market by considering tangible value of place. The identity of the place was analyzed as a spatial configuration, space organization, and sense of place through the place's physical setting, activities, and meanings by Edward Ralph. Based on the analysis by Ralph, we analyzed the traditional market and compare to the department store, which is the representative of large scale distributor, using comparative method. We performed quantitative and integrative analysis for the placeness and provide a way to appraise the worth of the traditional market by deviating from the traditional evaluation method.

NUI(Natural User Interface) allows users to directly interact with surrounding digital devices using their voices or body motions without additional input/output interface devices. Our study has been carried out on human users who play a tangible game with body motions in the NUI-applied smart space. ECG was measured for 60 seconds duration before and after playing the game to determine user stress levels, and the measured signals were analyzed through an improved Random Forest algorithm. In order to experiment by a supervised learning, users additionally input whether or not the user felt stress. Moreover, the improved algorithm showed 1.04% higher accuracy than existing algorithm.

Space is comprised by the movements of human beings, and draws a complex locus within it. That form seems to be complex of movement around in all directions of space axis, and be ever-changing process as time goes by. Although Human are able to move uninhibitedly, the movements are restricted to a narrow sphere during locomotion. However, the pattern of these movements delineates a certain frame within the space, and provides not only visual effects but also relevance tomovement itself. Also, critically dividing and organizing this sphere is what is realized into this tangible indoor space. This study recognized importance of human being as a core of making indoor space and brought out experimental approach on relationship human with space, and visually perceptual standpoint. And this presented the recent possibility of action and attitude though sight and walking by arranging space on the basis of modern artists' perception of human body.

This paper proposes a way to visualize the cyber space with respect to the offline space. In general, people have difficulties to understand the cyber space since it is not tangible and not visible. In businesses, both spaces depend on identical proposition of "salse of merchandise goods to customers". Here, 3 merchandise elements of "customers", "merchandise goods" and "salse" in the cyber space are compared to them in the offline spaces in order to visualize the cyber space in terms of businesses.

Tangible user interfaces have been developed in the area of Human-Computer Interaction for the last decades, however, the applied domains recently have been extended into the product design and interactive art. Tangible User Interfaces are the combination of digital information and physical objects or environments, thus they provide tangible and intuitive interaction as input and output devices, often combined with Augmented Reality. The research developed a design guideline for tangible user interfaces based on key properties of tangible user interfaces defined previously in five representative research: Tangible Interaction, Intuitiveness and Convenience, Expressive Representation, Context-aware and Spatial Interaction, and Social Interaction. Using the guideline emphasizing user interaction, this research evaluated installation in a science museum in terms of the applied characteristics of tangible user interfaces. The selected 15 installations which were evaluated are to educate visitors for science by emphasizing manipulation and experience of interfaces in those installations. According to the input devices, they are categorized into four Types. TUI properties in Type 3 installation, which uses body motions for interaction, shows the highest score, where items for context-aware and spatial interaction were highly rated. The context-aware and spatial interaction have been recently emphasized as extended properties of tangible user interfaces. The major type of installation in the science museum is equipped with buttons and joysticks for physical manipulation, thus multimodal interfaces utilizing visual, aural, tactile senses etc need to be developed to provide more innovative interaction. Further, more installation need to be reconfigurable for embodied interaction between users and the interactive space. The proposed design guideline can specify the characteristics of tangible user interfaces, thus this research can be a basis for the development and application of installation involving more TUI properties in future.
