Augmented Reality(AR) 기반의 스마트 글라스가 제공하는 일반적인 사용자 인터페이스는 카페 혹은 도서관 등과 같은 공공장소에서 사용이 꺼려지는 경향이 있다. 콘텐츠 조작 시 주변 사람들에게 관심을 받거나 프라이버시를 지키기 어렵기 때문이다. 이런 문제는 사회적으로 수용 가능한 범위 내에서의 사용자 인터페이스를 수행함으로써 해결할 수 있다. 본 논문에서는 스마트 글라스에서 사회적 수용성을 고려한 사용자 인터페이스의 기존 연구들을 분석하고자 한다.

The purpose of this study is to identify the factors affecting users' continuing use of Hedonic Information Systems(HIS). Focusing on users' post-adoption behaviors, this study proposes a research model which incorporates technology acceptance theory into expectation disconfirmation theory and investigates the causal relationship among five factors; perceived usefulness, perceived ease of use, disconfirmation, user satisfaction, and continuance intention to use a blog as HIS. The results show that satisfaction is significantly influenced by disconfirmation and post expectations(perceived usefulness and perceived ease of use), and in particular the impact of disconfirmation on user satisfaction is stronger than those of perceived usefulness and perceived ease of use. The results also indicate that while perceived usefulness and user satisfaction have significant impacts on continuance intention, perceived ease of use does not do so and has only an indirect impact on continuance intention through perceived usefulness and user satisfaction.

This research has been studied to analyze affecting factors for the consumer's acceptance to mobile advertisement by worldwide survey into mobile users of Korea, U.S. and Japan. Based on TAM & Flow theory, our research adopts some factors for a theoretical model such as entertainment, information, irritation, credibility, flow experience, attitudes and acceptance intention. And our research collects data from common consumers & students of each countries to try comparative study with mobile users who has different scope & environment of markets. This data was analyzed based on using AMOS, the structural equation modeling and a second-generation multi variant technique, and has gained distinct advantages over other technique.

This study aimed to demonstrate the effect of feedback type on users' subjective responses in a voice user interface. Feedback type is classified depend on information characteristic it involves; verification feedback and elaboration feedback. Error type is categorized as recognition error and performance error. Users' subjective assessment about system, feedback acceptance, and intention to use were measured as dependent variables. The results of experiment showed that feedback type has impacts on the subjective assessment(likeability, habitability, system response accuracy) of VUI, feedback acceptance, and intention to use. the results also demonstrated an interaction effect of feedback type and error type on the feedback acceptance. It leads to the conclusion that VUI should be designed with the elaboration feedback about error situation.

While the mobile application market is growing fast, the revenues of the majority apps are declining. Moreover, paid mobile application prices and purchases have been slow because of intensifying competition. However, the conventional studies focused only on the acceptance factor of mobile applications, so they cannot explain the phenomenon such as acceptance resistance for paid mobile applications. Therefore, our study tries to analyze the factors for the acceptance resistance of users for paid mobile applications. The research model in this paper, which is based on S-O-R model, verified through surveys how social influence and app characteristics affect user perception and how user perception affects to app resistance. The results of our study showed that paid mobile applications happened to be destroyed in front of the chasm because of the perceived loss. Consequently, the results implicate that the developers should lower the initial price and actively react to the negative reviews in order to lower the perceived loss. Moreover, the results verified that a sense of self-efficacy can lower application acceptance resistance by including personal properties to our research model as control variables.

Today smart devices such as smart phones, smart pads and tablets have become necessities of modern people in both daily life and business as they have widely proliferated. One of the most popular application areas of smart devices is a game-related area. Among these applications social network games, played with other users through social networks, are ranked top in their popularity. Though much research of PC games and online games have been performed, little research of social network games and the factors affecting acceptance of social network games are not vigorous yet. Therefore, we aim to analyze the factors and their structural influence on acceptance of social network games. We add a couple of factors such as Social interaction, Mobility, Subjective Norm, and Flow reg arding the characteristics of social network games and analyze the structural relationships among these factors using Structural Equation Modeling. Analysis results and implications are suggested with concluding remarks.

In the recent information-oriented age, various information technologies (ITs) have been introduced in construction industries. However, since construction ITs tend to be employed by the demand of the government or owners rather than the demand of information accepters (users), this tendency inhibits the spread of user-friendly construction ITs. In order to find these inhibitive factors, this research conducted practical studies, based on Davis' technology acceptance model, for construction ITs' acceptance according to the information accepters' (users) features. This study was hypothesized whether or not each inner and outer factors with respect to construction ITs are influential to the information accepters (users). As a result of this study, the primary factors which can maximize the usefulness and ease of use and should be considered when developing new information technologies were suggested.

Electronic payment is a very crucial function in electronic commerce. As electronic commercial transactions develop on a mobile basis, a variety of electronic payment services that can be conveniently used are appearing. In particular, mobile easy payment services improve the user's convenience of payment and give a positive effect on activating online transactions. In this study we investigate empirically the factors influencing the user resistance to mobile easy payment services. Especially, we compares the main acceptance factors of the mobile easy payment services with the main acceptance resistance factors of the services. By doing that, we derive the implications that could contribute to the vitalizations of the mobile easy payment service market. The research model includes "perceived risk" as a main acceptance resistance factor, and "easy of use" and "usefulness" as the main acceptance factors. The relationship among these three factors, "use conflict", and "user resistance" is expressed in the model. We analyze the model by Structural Equation Model. The results proves that all the research hypotheses are adopted except for the impact of "ease of use" on "use conflict", and that users of mobile easy payment services think of "usefulness" more important than "risk".

본 연구의 목적은 현재 급속히 확산되고 있는 온라인 뱅킹의 수용에 영향을 미치는 요인을 분석하기 위한 것으로, 기존 연구를 바탕으로 서비스 품질과 비용이라는 온라인 뱅킹 서비스 관점, 이용자의 태도의 관점(유용성, 용이성, 사용자 특성), 그리고 사회적 영향의 관점을 변인으로 추출하였다. 한편 성숙기에 접어든 인터넷 뱅킹 서비스와 도입기에 있는 모바일 뱅킹 서비스를 비교하기 위해 온라인 뱅킹 서비스 유형이라는 조절변수를 사용하였다. 연구 결과에 따르면, 유용성과 용이성, 개인사용자 특성, 사회적 영향, 서비스 품질, 비용의 모든 요인 이 온라인 뱅킹 서비스의 수용에 유의한 영향을 미치는 것으로 나타났다. 그러나 사회적 영향과 비용 은 인터넷 뱅킹과 모바일 뱅킹 서비스간에 영향 정도가 다른 것으로 나타났다.

본 연구는 기존의 인터넷 및 웹 광고에 대한 연구들을 바탕으로 동영상 UCC 광고에 대한 소비자의 태도와 수용에 영향을 미치는 요인을 분석해 보고자 하였다. 웹 광고 모델에서 사용된 정보성, 오락성, 부정적 자극 이외에 유용성과 용이성, 개인사용자 특성, 플로우, 그리고 인센티브를 새로운 변인으로 추가하였다. 연구 결과에 따르면, 오락성, 부정적 자극, 유용성 및 용이성, 플로우는 동영상 UCC 광고에 유의한 영향을 미치는 것으로 나타났지만, 정보성, 개인사용자 특성, 그리고 인센티브는 그렇지 않은 것으로 나타났다. 플로우는 동영상 UCC 광고의 수용에도 직접적으로 영향을 미치는 것으로 나타났으며, 동영상 UCC 광고에 대한 태도는 수용에 유의한 영향을 미치는 것으로 나타났다.
