With the introduction of the ubiquitous technology, the housing culture centers have demonstrated future housing image or technology. But Ubiquitous Home Services in the future housing were more focused on implementation of environment for the future than exhibition that consumers can experience. The purpose of this study was to identify ubiquitous home services which were realized in domestic future housing and to compare those with results of previous researches on demand for u-services. For this study, field study was conducted with 3 domestic future housings and 14 previous studies on demand of u-services were analyzed by the standard of residents demand. The results of the study showed that u-services for housework and leisure life more than those for security and health, were applied in the future housing. However, residents prefered u-services for security and control of indoor environment to those for housework and leisure life. As a result, it was found thatu-services which residents needed mainly were discordant with those that were displayed frequently in future housing. Also developing u-services reflected the needs of residents, a test bed has to be established in the future housing and then pre-evaluaiton can be conducted.

In this paper, we propose a home-networking service using mobile phone and ZigBee module. Recently, ZigBee is widely used for various applications due to its characteristics. Especially, it is generally adopted for home network services. We propose a new home network service model using mobile phones. In the proposed architecture, the mobile phones are connected to conventional home network appliances using ZigBee dongle. Also, several servers are implemented for service management. We implement the whole components of the proposed architecture and show the validity of the proposed method. With the proposed service structure, it is expected to provide various ubiquitous services for the user.

유비쿼터스 홈네트워크 ( uHome-net) 구현을 위해서는 다양한 센서들이 통합된 유무선 센서 네트워크에 연결될 수 있어야 한다. 본 논문은 제어 네트워크에 널리 사용되고 있는 LonWorks 기술을 uHome-net의 유무선 센서 네트워크에 적용한 사례를 소개하고, LonTalk 프로토콜이 탑재된 뉴런칩, 433.92MHz RF 트랜시버, 센서와 응용 프로그램으로 구성되는 LonRF 디바이스의 설계 및 응용 서비스 구현 결과를 설명한다. LonRF 디바이스의 응용 예로 실내에서 물체의 3차원 좌표를 측정할 수 있고 uHome-net과 연동되는 LonRF 스마트배지를 개발하였다. LonRF 디바이스 기반의 위치인식 서비스, 원격검침서비스, 원격경비서비스 등의 홈네트워크 서비스를 uHome-net 테스트베드에 구현하였다. 본 연구는 LonWorks 기술 기반의 센서 네트워크가 유비쿼터스 홈네트워크의 제어 네트워크로 적용할 수 있고, 개발된 LonRF 디바이스가 센서 네트워크의 무선 노드로 사용될 수 있음을 보였다.

The purpose of this study was to propose ubiquitous housing environment based on older residents' needs for ubiquitous(UT) home services. For this purpose, at the previous study which was the first stage of this study, UT home services by each elderly household based on spouse, income level, and health status were identified and this study finally proposed UT home services by each elderly household type according to residents' level of needs for UT home services. One to one interview with a structured survey questionnaire and illustration was implemented and 204 older residents who were composed of one of six elderly household types were responded. Among 6 types of elderly households, type 2 and 6 were the groups which had higher needs for various kinds of UT home services. Economic status and their health status were the key factors to determine their needs for UT home services. Type 4 and 7 were the groups to express their lower needs for UT home services due to their lower income level and good health condition. Ultimately, two floor plans for type 4 and 5 elderly households were developed to show applicable UT home services in each room of the house.

It is essential to investigate the structure and the main characteristic of Home USN (Ubiquitous Sensor Network) technologies in built ubiquitous environment while designing future residential space. For this study, three different housing types have been selected to implement ubiquitous technologies for residential space; those are regular, elderly, and single residence units. It is certain that efficiency of ubiquitous home design is improved if main components of each specific housing type are analyzed precisely in digital way and design models are prepared accordingly. Ubiquitous technology, in conclusion, has to be applied not on)r with systematical mechanism or electronic setting but in human-centered atmosphere as well, keeping with deep consideration for bio-housing service factors in eco-friendly surrounding; we call this Ubiquitous Humanism.

The purpose of this study was to analyze the customer demand for design development of digital convergence furniture in the living space of the ubiquitous home. This study used the individual survey method and was collected from July 1 to 20, 2008. The frequency and percentage were used for data analysis by SPSS window's 12. The results of the study were as follows: The first, a lot of survey targets were 30-40 years old, university graduates, over 50,000,000 won in annual income and 30-40 pyung in house size. The second, what types of activity were carried out in the living room were acquisition of knowledge>entertainment activity>communication activity>household chores. The third, what types of furniture were used in the living room were A/V furniture>table>sofa>computer table>bookself. The forth, customers preferred to picture telephone service in sociality, home-theater service in entertainment and home appliances remote control service in information service. The fifth, the digital functions which can integrate with the living roon furniture, in the item for A/V furniture, was front door control function which recognizes visitors with the screen. In the item for table was function to search internet and for sofa was self purification function. Finally, the digital convergence furniture is not only for one activity but also for various types of activities that can comprehensively function to materialize the concept of comfortable furniture in the living space.

유비쿼터스 환경은 가전, 센서, 디바이스 등의 기기들로 연결된 네트워크를 이용해서 사용자에게 다양한 서비스를 통해서 제공될 수 있다. 현재, 홈네트워크 환경과 텔리매틱스등의 분야에서 개방형 서비스 게이트웨이가 이를 위해서 이용되고 있으며, 이 게이트웨이를 통해서 서비스의 설치, 배치 및 실행 환경을 제공한다. 서비스 게이트웨이는 유비쿼터스 환경내의 다양한 디바이스들과 이들 서비스들 간의 중간 연결 역할을 담당하며 서비스들 간의 상호 작용을 지원한다. 유비쿼터스 환경에서는 사용자와 디바이스들은 이동성의 특징을 가지기 때문에 이를 지원하는 서비스는 서비스 게이트웨이간의 이동성을 지원할 수 있어야 한다. 그러나 현재 이용되고 있는 서비스 게이트웨이에서는 서비스의 배포 및 설치 단위인 번들 코드의 다운로드를 통한 원격 설치를 지원하지만, 실행 중인 서비스의 이동을 지원하지 못한다. 본 논문은 개방형 서비스 게이트웨이 프레임워크들 간의 서비스 이동성을 보장하기 위해서 동작되고 있는 서비스의 이동을 관리할 수 있는 시스템을 개발한다 서비스 이동 관리 시스템은 OSGi 프레임워크에서 동작될 수 있기 위해서 OSGi 표준 스펙에 맞게 설계 및 구현하며, 이동성을 갖는 서비스에 대한 관리를 가능하게 함으로써 유비쿼터스 환경에서 서비스의 이동성을 보다 효과적으로 지원할 수 있다.

Objective: The main objective of this study is to propose a user-centered assessment metric for ubiquitous services. Background: As the ubiquitous era took off, the interactions between ubiquitous services and users have come to take an important position. It is essential to conceptualize a new assessment model that considers human-system interaction capability with a user-centered design perspective. Method: The evaluation model for the interactivity of ubiquitous service was approached from the concept of usability and inter-personality of services. As a validation study, suggested assessment metric was utilized to evaluate the u-Home service. Priority weighting of each assessment metric was derived using the quantification type-I analysis. Results: To evaluate interactivity, this study suggested a quantitative metric for user testing performed after classifying the interactivity characteristics to contextualization; ubiquity; user experience; and service capability. Conclusion: This study suggest the metric for the ubiquitous service that are experienced in real life, and introduced the concept of ubiquitous service interactivity. Application: The suggested evaluation metric can be used to evaluate interactivity level of ubiquitous service and identify the potential problem and usability requirements at the early stage of service development.
