본 연구는 생활환경 지능화(Ambient Intelligence 이하 AmI)의 기술적 변화와 Ambient Display와 Ambient Media 등을 바탕으로 Ambient Art의 개념과 특성을 도출하고, 이를 통한 감성 커뮤니케이션 연구의 가능성을 살펴 보았다. 앞으로의 사회는 AmI의 환경으로 변화해 갈 것이다. AmI란 인간 중심의 지능형 컴퓨터, 네트워크, 인터페이스 기술을 기반으로 우리의 주변환경이 지능을 갖게 된 상황을 말한다. 유비쿼터스 컴퓨팅, 무선 네트워크와 같은 AmI의 기술들은 새로운 미디어를 만들고 이러한 미디어는 우리의 인식과 커뮤니케이션 방식을 변화시키고 있다. 기술의 발달은 빠른 반면, 그 기술을 사용하는 사람의 적응속도는 느리기 때문에 사람이 어떻게 새로운 기술에 적응할 것인가는 핵심적 문제다. 감성 커뮤니케이션 연구는 이런 문제들을 해결하는데 큰 도움을 줄 뿐만 아니라, 사람들의 감성 욕구까지 채워줄 수 있다. 그러나 감성은 순간적이며 복합적이고 무의식적으로 발생하고 수시로 변하기 때문에 연구하기가 쉽지 않다[1]. 본 연구에서 정의한 Ambient Art는 일상의 환경에서 자연스럽게 접할 수 있으며 사용자의 직접적인 인지가 없이도 감상할 수 있는 예술로, 기술이 환경에 스며들게 되는 것처럼 예술이 환경에 스며들어 궁극적으로 언제 어디서나 감상이 가능한 전시공간의 유비쿼터스화를 지향한다. 이러한 Ambient Art는 감성커뮤니케이션 연구의 새로운 대안책으로 생각해 볼 수 있다. 본 연구에서는 Ambient Art의 5가지 특성을 상황인지, 분위기, 개인화, 상호작용, 자가성장으로 나누어 살펴 보았다. 또한 Ambient Art의 개념과 특성을 반영한 작품 City Forest를 제안하였다. 이 작품은 사람들의 활동에 의해 달라지는 시각적 감성 전달을 통해 이성보다 앞서 있는 감성을 자극하여 개인과 환경, 환경과 환경끼리의 상호 작용을 촉진시켜 Ambient Art를 통한 감성 커뮤니케이션을 보여주었다는데 의의가 있다.

Analyzing adaptive possibilities of agents in multi-agents system, we have discovered new aspects of ambient intelligence in distributed modular systems using intelligent building blocks (I-BLOCKS) [1]. This paper describes early scientific researches related to technical design, applicable experiments and evaluation of adaptive processing and information interaction among I-BLOCKS allowing users to easily develop ambient intelligence applications. The processing technology presented in this paper is embedded inside each DUPLO1 brick by microprocessor as well as selected sensors and actuators in addition. Behaviors of an I-BLOCKS modular structure are defined by the internal processing functionality of each I-Blocks in such structure and communication capacities between I-BLOCKS. Users of the I-BLOCKS system can do 'programming by building' and thereby create specific functionalities of a modular structure of intelligent artefacts without the need to learn and use traditional programming language. From investigating different effects of modem artificial intelligence, I-BLOCKS we have developed might possibly contain potential possibilities for developing applications in ambient intelligence (AmI) environments. To illustrate these possibilities, the paper presents a range of different experimental scenarios in which I-BLOCKS have been used to set-up reconfigurable modular systems. The paper also reports briefly about earlier experiments of I-BLOCKS in different research fields, allowing users to construct AmI applications by a just defined concept of modular artefacts [3].

현대 도시의 새로운 이미지 창출을 위해서 공공예술은 중요한 요소이다 과거 조형적 작품으로 이루어지던 공공예술은 미디어아트, 인터렉티브 아트등 새로운 예술분야로의 접목이 늘어나는 경향이 나타난다. 그러나 인터렉티브 아트가 공공예술로 정착되기에는 가기고 있는 문제점이 있다. 이를 보완하기 위해서 본 논문에서는 엠비언트 아트(Ambient Art)를 활용하였다. 엠비언트 인텔리전스(Ambient Intelligence)에서 파생된 개념으로의 엠비언트 아트는 Ambient Display와 Ambient Media 등을 사용하여 사용자의 주의 없이도 환경정보를 활용하여 인터렉션을 일으켜 작품에 생명력을 부여하는 예술장르를 말한다. 기존 연구에 의하면, 엠비언트 아트는 상황인지, 개인화, 분위기, 상호작용, 자가성장의 5가지 특성을 지닌다. 그러나 엠비언트 아트가 공공예술로 사용되기 위해선 소통, 보안, 선택권의 3가지 요소가 필요하다. 공공공간이 지니고 있는 특성과 공공예술이 가지는 파급효과를 고려하면, 3가지 요소가 중요하다. 보다 높은 수준의 소통과 과도한 관객의 상황정보 수집으로부터의 보호, 관객의 작품 참여 선택권은 엠비언트 아트가 가져할 구성요소이다. 본 논문에서는 3가지 요소를 포함하는 새로운 장르의 공공예술(New Genre Public Art)의 공공 엠비언트 아트(Public Ambient Art)를 제시하여 대안을 마련하는데 의의가 있다.

In this paper we propose an improved version of the computational integral imaging reconstruction (CIIR) for visualizing a partially occluded object by utilizing an image inpainting technique. In the proposed method the elemental images for a partially occluded three-dimensional (3D) object are recorded through the integral imaging pickup process. Next, the depth of occlusion within the elemental images is estimated using two different CIIR methods, and the weight mask pattern for occlusion is generated. After that, we apply our image inpainting technique to the recorded elemental images to fill in the occluding area with reliable data, using information from neighboring pixels. Finally, the inpainted elemental images for the occluded region are reconstructed using the CIIR process. To verify the validity of the proposed system, we carry out preliminary experiments in which faces are the objects. The experimental results reveal that the proposed system can dramatically improve the quality of a reconstructed CIIR image.

The goal of Ambient Intelligence (AmI) is to build a smart environment for users where they are supported in some of their activities by many interaction mechanisms. The diversity of AmI characteristics requires special support from Operating Systems (OSes). In this paper, in order to support a conscious choice of an operating system for any specific AmI application, features requested by AmI systems were characterized and defined considering various applications. Then, characteristics of existing Operating Systems have been investigated in the context of AmI application support to relate their key characteristics to the typical requirements of AmI systems. Qualitative mapping table between AmI characteristics and as features has been proposed with an illustration of how to use it. As no as completely covers the range of characteristics required by AmI systems, challenging issues are summarized for the development of a new as and a product line of OSes.

This study presents a reference model (RM) and the architecture of a cognitive health advisor (CHA) that integrates information with ambient intelligence. By controlling the information using the CHA platform, the reference model can provide various ambient intelligent solutions to a user. Herein, a novel approach to a CHA RM based on evolutional cyber-physical systems is proposed. The objective of the CHA RM is to improve personal health by managing data integration from many devices as well as conduct a new feedback cycle, which includes training and consulting to improve quality of life. The RM can provide an overview of the basis for implementing concrete software architectures. The proposed RM provides a standardized clarification for developers and service designers in the design and implementation process. The CHA RM provides a new approach to developing a digital healthcare model that includes integrated systems, subsystems, and components. New features for chatbots and feedback functions set the position of the conversational interface system to improve human health by integrating information, analytics, and decisions and feedback as an advisor on the CHA platform.

Integral imaging is considered as a next-generation 3D display which can display 3d imaging in space using lens array. The performance of integral imaging systems depends on several factors including display panel, lens array, imaging devices and so on. In this paper, we develop a unifying framework to evaluate the resolution of integral imaging systems under fixed resource constraints. The proposed framework enables one to optimize the system performance. To show the feasibility of the proposed method, we carry out Monte Carlo simulations based on this framework and present the results.

In this paper, in order to solve the problems of a narrow viewing angle and the flip effect in a three-dimensional (3D) integral imaging display, we propose an improved system by using an eye tracking method based on the Kinect sensor. In the proposed method, we introduce two types of calibration processes. First process is to perform the calibration between two cameras within Kinect sensor to collect specific 3D information. Second process is to use a space calibration for the coordinate conversion between the Kinect sensor and the coordinate system of the display panel. Our calibration processes can provide the improved performance of estimation for 3D position of the observer's eyes and generate elemental images in real-time speed based on the estimated position. To show the usefulness of the proposed method, we implement an integral imaging display system using the eye tracking process based on our calibration processes and carry out the preliminary experiments by measuring the viewing angle and flipping effect for the reconstructed 3D images. The experimental results reveal that the proposed method extended the viewing angles and removed the flipping images compared with the conventional system.
