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.

The purposes of this study were to identify the needs for ubiquitous home services in residential environment of elderly single or elderly couple households living without children and also to analyze the differences of the needs according to their demographic and housing characteristics. For this study, a literature review and field works on ubiquitous home services for older people were performed. Also, 1 to 1 interview by using the questionnaire which was developed by the researchers in this study was conducted and 270 elderly residents in Seoul and Gyeonggi-Do were responded. Seventy-one ubiquitous service items which were adopted to home electronic appliances and furniture for older people were developed for 1 to 1 interview questionnaire. The major findings of the study were as follows: the elderly residents expressed highest need for ubiquitous home service items related to safety and health issues. Among ubiquitous service items applied to gas stove, vacuum cleaner, TV, telephone, sofa and toilet, the items related to safety and health aspects were most needed. And residents' income level and health status were the two major variables to show group differences in the need of ubiquitous home services. In other words, the elderly residents who were high income and frail tended to have the highest demand for ubiquitous home services adopted to home electronic appliances and furniture.

Recently, the korean statistical information service reported that the elder people aged over 65 years take 11 percentage point of all population, indicating that the hyper-elder era will advent shortly. As a result, there are remarkably increasing demands for providing self-organizable home agent system for elder people. Of the home agent system, the ubiquitous home service is known to be useful to overcome this problem. However, current ubiquitous home services limited to provide functional services, and it can be observed that there is lack of consideration for elder-support products which are closely interacted with elder people in the living situation. In this paper, we analyze senior aids products that can be combined to the ubiquitous home service, and propose design procedure for senior aids products that can be applied to self-organizable ubiquitous services. We studied characteristics of elder people, current state of affairs for senior aids products, and home services that are highly required by elder people. Moreover, we observed that the ubiquitous home services related to health, safety, and amenity are urgently needed, and those services can be categorized according to residential areas. Following those observances, we proposed a design principle based on the universal design paradigm to provide self-organizable ubiquitous home service environment for elder people using senior aids products.

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.

With the introduction of the ubiquitous technology, the housing culture centers of construction companies have demonstrated future housing image and technology. However, ubiquitous home services are technology oriented items. The purpose of this study was to identify u- services which were realized in domestic future housing and to compare those with services the residents needed greatly refer to researches related to demand for u-service. For this study, field studies were conducted with 3 domestic future housings and precedent studies on demand for u-service were analyzed according to the standard of residents' demand. The results of the study showed that residents prefer u-services for security and control of indoor environment for housework and leisure life. As a result, u-services which residents needed mainly did not correspond with those that were displayed in future housing.

The purpose of this study is to introduce ubiquitous home services for the aged. In comparison with general ubiquitous homes, ubiquitous homes for the aged have two major characteristics. First, the service contents should be expanded and strengthened. Second, the services should be customized to each individuals. The primary objective of a ubiquitous home for the aged is health care. The three affordances for this objective are 1)prevention of sickness and reducing the speed of aging process, 2)technical assistance for disability, 3)recovering and enhancing the physical and cognitive function. For this purpose this paper analyses the characteristics of the aged and current ubiquitous technology and ubiquitous home service, thus providing an outline for ubiquitous services necessary for aged people.

Ubiquitous services are high duality and differentiated services which are provided for users by recognizing the context of users and environmental conditions actively. In this case, context-aware middleware is one of the most important technologies required to implement the ubiquitous services. In this paper, we propose a method for providing ubiquitous services in a specific user space effectively and monitoring human bio-signal sensors. That is, the design and implementation of intelligent home service middleware and monitoring human bio-signal sensor based on context awareness is discussed here. Context information from various sensors is gathered, and suitable services are inferred and provided to users by the middleware system. In our approach, user services can be modelled easily by using facts and rules, and the system can be extended easily to support various ubiquitous services other than intelligent home services also. The system can be integrated with external applications and legacy systems effectively by using various protocols such as RMI, socket and HTTP, XML and Zigbee etc. We have designed and evaluated various facts and rules for intelligent home services in real environments. Functionality evaluation with the system shows that ubiquitous services can be provided to users effectively in a home environment.

Fruition for a diverse uIT(Ubiquitous Information Technology) service is currently required through the convergence of what is known as ubiquitous computing technology. In recent years, with the rapid growth of the need for information services, heavier demands have been made upon the supply of high-quality multimedia services that require a high bandwidth. Today, various home network solutions have been proposed to manage these service smoothly and a system able to deal with various types of network traffic without delays. In addition, in established home network environments that mix wired and wireless networks, along with the steady evolution of wireless network technology and the earnest development of ubiquitous computing technology, sensor-based wireless networks have emerged as a core solution for home networks. In this paper, a sensor network-based home control system supporting the next generation home gateway system for ubiquitous home environments is designed and implemented.

The purposes of this study were to identify living behavioral patterns in of single or couple elderly households in residential environment, to find out ubiquitous home services for the elders, and finally to suggest the ubiquitous home services according to each household's type. For this study, literature review, field works for ubiquitous home services for the elders, and in-depth interview and observation by 74 elderly participants were conducted. The major findings of the study were as follows: single or spouse elderly households were classified into 8 types according to the combination of their household types, income level, and health status. Among 8 types, 2 types were excluded for final analysis due to small sample size. Living behavioral characteristics of 6 types were analyzed and the behavioral pattern of each type was drawn. Based on this behavioral pattern of each type, ubiquitous home services which meet the needs of each type were suggested. The implications and limitations of this study were also discussed and the suggestions for further studies were recommended.
