The concept of Smart home is receiving a huge attention as a future living environment because of its advantages for elderly and disabled to maintain their quality of life. Smart home is a place equipped with integration of technology and services and closely intertwined with occupant's lifestyle. Therefore it is critical to consider the user's actual needs for ensuring satisfaction. However despite growing researches on user values for smart home, there have been few studies clearly categorizing smart home service and stating user values depending on characteristics of service. Thus, the aim of this research is to classify smart home services on user's perspective, and reveal user values for each smart home services. Through the in-depth literature review, we elicited technology-related user values and service-related user values, and state classification for smart home service. Also the relationship between user values and each smart home services were revealed. The results of this research should help to reflect user's actual needs for designing smart home services.

This study analyzed the domestic and foreign cases of the existing smart home service and grasped the needs of the future smart home service in the future of the Internet of Things. As with all smart homes, the effectiveness of future use is important when comparing needs and random services according to user usability and destination patterns. In order to improve the reliability and to promote the development direction, we conducted a questionnaire survey of 110 people in 20 ~ 30 age group. The survey shows that the reliability of the smart home service is low. The low trust factors include: 1. lack of usability; 2. lack of device recognition; 3. lack of specialization services. Since the smart home service is still in the early stage, various smart home services and ecosystem should be constructed according to user's needs.

This study conducted empirical analyses to investigate the factors affecting the intention to use smart home services. Based on the previous relevant studies, the characteristics of smart home service were found to influence on the intention to use smart home service, and four variables(ubiquitous connectivity, reliability, context awareness, and security) concerning the service characteristics could be derived. And referring to the technology acceptance model(TAM), the updated TAM, IS success model, and the theory of reasoned action(TRA), three variables such as perceived ease of use, perceived usefulness and subjective norm were also likely to affect the intention to use smart home service, and the user innovativeness was inferred to play a role of moderating variable. In order to examine the research model and the hypotheses which could describe the relationship of the above mentioned variables, this study surveyed 447 people who were currently using or would use the smart home services, and then tested the hypotheses for 436 valid responses. The results of hypotheses testing showed that reliability, context awareness, and security have a significant effect on perceived usefulness and on perceived ease of use. However, it was found that ubiquitous connectivity significantly affected perceived usefulness but did not affect perceived ease of use. And perceived ease of use, perceived usefulness and subjective norm had significant effect on the intention to use smart home services. Also, user innovativeness as moderating variable was found to significantly influence on the magnitude of the relationship between ubiquitous connectivity and perceived usefulness and on that between reliability and perceived ease of use. This can be interpreted as the findings implying that innovative smart home-service users are likely to feel the smart home-services more useful than ordinary users when the degree of ubiquitous connectivity is higher, and are likely to perceive the use of smart home-services to be easier than ordinary ones when the degree of reliability is higher.

The purpose of this study is to suggest functional priority to increase probability to be adopted by single-person household by designating single-person household as potential early adopter of smart home service. Smart home service is spread slowly for its value. This study applied diffusion of innovations theory to solve this problem. Single-person household who has no other family member who can take care of household is chosen as potential early adopter. This study tried to find grounds of functional priorities through an online survey. The survey questionnaires were composed as following. First, representative attributes of single- person household were reviewed, then measuring questions according to the attributes were recomposed based upon preceding study. After that, concept and status of smart home service were reviewed. and smart home service functions to be measured in this study were selected through analysis based upon representative cases, then Measuring questionnaire were made were three factors which chosen by referring to preceding study about perceived attributes of innovations applied to selected functions. As a result of analyzed 62 responses, except excluded functions which has perceived any special value, set priorites with 9 functions. These functional priorities obtained from these studies will play a role as fundamental data to provide valuable service to single-person household and have a meaning as a starting point to increase rate of adoption for smart home service.
