현재의 유비쿼터스 환경의 홈 네트워크 제품 사용자는 단일 사용자가 아닌 다수의 사용자가 사용하는 네트워크 행태를 취하고 있다. 변화하는 사용환경과 시스템들은 현재와는 다른 요구사항을 가지고 있으며, 이에 따른 사용자 중심의 디자인과 제품 인터페이스 체계의 연구활동은 국내외에서 활발하게 이루어지고 있다. 다양한 모바일 디바이스 및 홈 네트워크 제품의 보급화가 빠르게 성장하면서 이를 쉽게 제어하기 위한 다양한 제어방식이 연구되고 있다. 이중 음성인식기술을 비롯한 표정은 안면표정인식기술의 개발이 활발히 진행되고 있다. 모션감지 센서를 활용한 사용자 제스처 콘트롤 체계는 아직까지는 초보적인 단계에 있으나, 제품 제어에 있어서 향후 근미래에는 자연스러운 인터랙티브 인터페이스의 활용도가 높아질 전망이다. 이에 본 연구에서는 효과적인 디바이스 제어를 위한 제스처 유형의 자연스러운 사용언어체계 개발 방법 및 결과 그리고 사용자 맨탈모델와 메타포 실험을 통한 연구내용을 정리하였다. 기존 사용자의 제스처 유형의 자연스러운 사용언어를 분석하면서 디바이스 제어방식으로서 활용 가능성을 검토할 수 있었으며, 동작 감지 카메라 및 센서를 활용한 새로운 디바이스 제어방식 개발과정의 연구를 통하여 제스처 유형의 자연스러운 언어 체계 개발 및 과정을 정립하였다.

The Internet of Thing (IoT) will be a very important core technology to implement Intelligent Smart Home Network and it will take charge of an important role connected to Smart Phone, Cloud Computing in the Ubiquitous environment. In this paper, Internal Autonomous Regulation by human autonomic nervous system was studied and its core mechanism was applied to the design of IoT based Autonomous Regulation System for Intelligent Smart Home Network. We proposed an autonomous regulating mechanism in which the factors of Temperature, Humidity and Illumination are automatically adjusted as they communicate with the connected things.

In ubiquitous environment where various kinds of computers are embedded in persons, objects and environment and they are interconnected and can be used in my place as necessary, different types of data need to be exchanged between heterogeneous machines through home network. In the environment, the efficient processing, transmission and monitoring of image data are essential technologies. We need to make research not only on traditional image processing such as spatial and visual resolution, color expression and methods of measuring image quality but also on transmission rate on home network that has a limited bandwidth. The present study proposes a new motion vector estimation algorithm for transmitting, processing and controlling image data, which is the core part of contents in home network situation and, using algorithm, implements a real time monitoring system of multi dimensional images transmitted from multiple cameras. Image data of stereo cameras to be transmitted in different environment in angle, distance, etc. are preprocessed through reduction, magnification, shift or correction, and compressed and sent using the proposed metamorphosis hierarchical motion vector estimation algorithm for the correction of motion. The proposed algorithm adopts advantages and complements disadvantages of existing motion vector estimation algorithms such as whole range search, three stage search and hierarchical search, and estimates efficiently the motion of images with high variation of brightness using an atypical small size macro block. The proposed metamorphosis hierarchical motion vector estimation algorithm and implemented image systems can be utilized in various ways in ubiquitous environment.

Since the late 20th century, digital technology has changed our environment in many ways. The representative advanced homes today embed digital facilities such as a sensor infrastructure, a networking system, and ubiquitous display. In this point of view, this study was intended to define the apartment residents' diverse needs for digital home design. The subjects are 400 wives who live in Busan. The findings are as follows; (1) The factors of the housing activities are extracted as 'guest hosting,' 'family entertaining,' 'digital network,' 'daily domestic affair,' 'non-daily domestic affair,' 'media using,' and 'bathing & exercising' activities. (2) The 'digital network activities' occurred more frequently in the households with non-employed wife and preschool children, and with employed wife and preschool and elementary school children. (3) The factors of the digital home system were extracted as 'safety & maintenance,' 'health & convenience,' 'educational & housekeeping,' and 'cultural & entertaining' systems. (4) The needs of non-employed wives for the safety & maintenance and the educational & housekeeping systems are varied by family life cycle and wife age. While, the needs of employed wives for the educational & housekeeping and the culture & entertaining systems are varied by dwelling-size and wife age.

Digital home devices aims at providing the multimedia service which is not limited at time and space in home network environment. However, it is incapable of the fair use of consumers who legally buys contents, and causes damage to the contents providers owing to the indiscriminate distribution and use of illegal contents. DRM system appeared to solve this problem cannot protect the license stored on digital home devices and manage license by redistribution. This paper proposes a license audit model which makes an inspection of illegal access, modification and redistribution and reports alert logs to server.

RFID technology of Ubiquitous core technology was used the local parts of Traceability System in past, but the various parts of u-Healthcare, Home networks, Telematics, and etc. in today on the one hand, according to be interested in the home networks technology and develope it, we are searching about how to apply RFID technology in home networks. This paper is designed and implemented the system delivered tag information to the application of home networks and controled RFID reader remotely by the bundle implemented RFID reader process methods based OSGi framework platforms.

In this paper, we describe a development of a Bluetooth Access Point for the WAN connection of home network devices. Especially, users can access the PSTN at home instead of expensive digital cellular network through the AP, using the 'one-phone', which is the Bluetooth enabled cellular phone. The simultaneous benchmark test about telephone service and LAN access service shows the perfect compatibility and reasonable performance of the access point. The one-phone service can become a convergence of wired and wireless communication through the AP.

Upon the changes of human life style due to the distribution of ultra-high speed internet services and the development of high-tech information equipment, the idea of necessity fer home networking has been widely accepted. Thus, "embedded ethernet module" was designed in this paper for the stabilization of home networking by using 8051 MCU, Hardwired TCP/IP (W3150A). By executing remote software on established simple web-server on the target machine, controlling electric equipment became available elsewhere. With this module, establishing a low-cost home automations system would become possible in a ubiquitous society.

We derive priority decision making on healthcare service technology standardization in the home network through the decision support process with industry professionals. We configured a research group with 4 industrial areas including Industry, Academic, Research Institution and Medical Institution. And we also applied AHP methodology for the priority decision making. The research group decides an evaluation criteria which are consisted of marketability, technology, ripple effect, strategy for national policies in order to make a priority for healthcare service on a home network. And it is also decided 7 fields and 24 sub-fields, technically. In order to make a priority for the standardization, we use an AHP methodology, that is more objective and feasible, as a decision tool. After two-phase survey that consists of paper survey and face to face meeting, we get a conclusion that home healthcare content is at the top and then wireless home network follows it.

This paper implemented the u-Healthcare Context Information System (HCIS) supporting ubiquitous healthcare by using location, health and titrating environment information collected from sensors/devices equipped in home for healthcare home service. The HCIS is based on the Distributed Object Group Framework (DOGF), a management model which can customize distributed resources, and manages various context information, applications and devices as a group in healthcare home environment, as one more logical units. Also, this system provides continuous healthcare multimedia service considering a resident's location using Mobile Proxy, and the healthcare context information through Context Provider to a resident in home. For verifying execution of our system, we implemented the seamless multimedia service based on resident's location and the prescription/advice and schedule notification/alarm service as healthcare applications in home. And we showed the executing results of healthcare home service by using service device existed in the residential space on which the resident is located according to the healthcare scenario.
