Objective: The purpose of this study was to investigate major factors influencing adoption of smartphone to promote its use by older adults. Background: Despite increasing proportion of elderly people and elderly market, the proportion of elderly smartphone user is still relatively small compared to whole smartphone users. Thus, we need to find out major factors influencing adoption of smartphone to increase proportion of elderly smartphone users. Method: Seven major factors were extracted from 36 survey questions using factor analysis. Regression analysis was also applied to determine specific factors affecting intention of use based on user versus non-user of smartphone, age, gender, and educational background. Results: As results of factor analysis and regression analysis, major factors influencing adoption of smartphone for elderly users were significantly different according to gender, age, educational background based on smartphone users or non-users. Conclusion: The result of this study identified major factors influencing adoption of smartphone for the elderly and provided basic information related to adoption of smartphone according to elderly people's characteristics. Consequently, we can expect to reduce the information gap and to improve quality of life for the elderly. Application: The development and marketing strategy could be applied differently based on the factors influencing adoption of smartphone. It is also possible to develop a prediction model for smartphone adoption according to elderly users' characteristics.

The purpose of this study is to investigate the research model attempting to explain factors influencing consumers' attitude towards Smartphone adoption and behavioral intention to use a Smartphone. The 357 sets of data are tested against the model using SEM (structural equation model). The research results reveal that organizational and social influences, consumers' self-actualization, and trust affect consumers' attitude towards Smartphone adoption, and behavioral control influences behavioral intention. Implications of the findings suggest that Smartphone should be approached with a holistic view, suggesting that Smartphone research should emphasize Smartphone as a convergent device including both hardware and software with services and applications. Research results are discussed, and limitations of the current study and future research are presented.

This study aims to identify and analyze the roles of incumbent smartphone's brand loyalty in smartphone adoption considering rational judgments and aesthetics evaluation. For this purpose, two hypotheses are developed based on dual process theory. For the validation of these hypotheses, G4, a smartphone brand from LG, was adopted as the target smartphone. The participants were university students in Korea, non-LG smartphones. In result, two hypotheses were statistically supported. This study showed that users with higher brand loyalty toward incumbent smartphone would be more sensitive to rational judgment while lower brand loyalty more sensitive to aesthetic evaluation.

Contemporary smartphone competition is generally described as the battle between Apple's proprietary platform and Google's open platform. However, this competition is not limited within smartphone adoption itself. User's pre-adoption of one mobile platform via smartphone can be connected to the post-adoption of the same mobile platform based on the other smart devices (e.g. smart pad). In this study, we investigate whether user's preference to a certain platform is persistent over mobile ecology, from the pre-adoption of one smart device to the post-adoption of following devices. For this investigation, we adopt the dual-model as the ground theory, where post-adoption of IT product is explained by both dedication and constraint factors. The empirical testing first evidences that dual model works well as our research model for identifying the reasons of post-adoption. Next, we group our data into two parts in order to compare the switching behavior of iPhone users and Android phone users. iPhone users show much lower switching rate to Android based smart pads, while Android phone users show higher churn rate to iPad (49.3% : 96.3%). Especially, satisfaction showed much stronger effect than switching cost on the continuing intention of existing platform, when the analysis is given to the iPhone user's group. From this result, we can conjecture the relatively stronger loyalty of iPhone users. More managerial implications on the mobile platform strategy are driven.

This study examines the roles of user resistance and social influences on the acceptance and continuous usage of smartphones at different stages of adoption. The respondents were classified into three groups according to their innovation adoption stage : non-user group, the potential user group and the trial user group. Theories relevant to user resistance, social influences including normative social influences and informational social influences, as well as user adoption and continuance behavior were reviewed and integrated into our research model. In order to verify the proposed structured equation model, we conducted an online survey by targeting mobile phone users and collected data to be analyzed through a partial least squares (PLS) test. This study tested whether there exists differences in the effects of user resistance and different types of social influence on user's adoption or continuance intetion among these three groups. The results showed that user resistance exists in all adopter groups and that it has significant negative influences on intention to use a smartphone. The findings also revealed that user resistance can be enhanced or resolved by two types of social influence; informational social influence resolves user resistance regardless of the adopter category, while normative social influence enhances the user resistance of potential users. Furthermore, the findings show that social influence regardless of the type positively affects user intention. Several theoretic and practical implications pertaining to the results are discussed.

As network technologies evolve and so-called smart technologies appear, applications of smartphones are being applied in widespread areas. In general, the adoption of smartphones is different from the adoption of information systems. Thus, we tried to find out factors which may affect the user acceptance behavior. However, there have been some academic studies that analyzed the factors that affect user acceptance of smartphones, and their relationships. Under this academic background, we develop a model to examine how smartphones are accepted by users based on technology acceptance model. The theoretical model is validated through an online survey of smartphone users from two universities in Seoul, Korea. The results reveal that the users will have positive attitude towards adopting the smartphone when they perceive that the usage of smartphones is useful. We also find that the perceived usefulness of the smartphone is affected by the perceived ease of use and the media richness. The results also suggest that the perceived ease of use is determined by the self-efficacy whereas the intention to use smartphones is determined bv the perceived usefulness, the self-efficacy, and the attitude toward smartphnes' usage. Theoretical and practical implications are discussed.

본 논문은 디지털미디어 시대의 아이콘인 스마트폰 채택 원인을 알아보고자 하였다. 스마트폰과 같은 미디어는 첨단 기기인 동시에 사회적 미디어이기도 하다. 스마트폰에 대한 채택 요인은 이미 연구가 되어져왔고 이를 토대로 국내 외국인 유학생들의 스마트폰 채택 요인도 유추해볼 수 있을 것이다. 본 연구는 정보기술수용모델 이론에 근거해서 스마트폰의 기술적 속성과 개인적 속성 그리고 사회적 속성을 독립변인으로 도출하였다. 매개변인으로는 지각된 용이성과 지각된 유용성을 적용하였다. 연구 결과 기술적 속성 중 서비스 품질과 개인적 속성 중 혁신성 등은 기존 이론과 달리 지각된 용이성 및 지각된 유용성에 긍정적인 영향을 미치지 않는 것으로 나타났다. 이는 스마트폰이 이미 익숙한 사회적 미디어라고 할 수 있겠다. 후속 연구를 위해서 다양한 변인의 적용 및 전국 단위의 샘플링을 통해서 보다 객관적인 연구를 하면 스마트폰과 같은 새로운 미디어의 채택 요인을 보다 정교하게 해석할 수 있을 것이다.

In recent years, smartphone is the most widely used ubiquitous functionality. People do not want to just call other people any more by using a cellular phone; they want to connect to the Internet and use various applications. Hence, cellular phones need to become smart. A smartphone has an operating system and many applications. Specifically the goals of this research are; (1) to suggest theory framework of acceptance about smartphone based on TAM, (2) to examine relationships between exogenous variables. The research model and hypotheses were developed based on the theories of technology acceptance model. Questionnaire was used to collect data. The analysis of this study is designed as individual level to examine the causal relationship among variables. The the reliability and validity of data was tested by explanatory factor analysis, Cronbach's alpha coefficient, confirmatory factor analysis, and correlation analysis. Also, the structural equation model(SEM) analysis was performed to test the usefulness of the model. The analysis results revealed that social norms and individual innovation are major influential variables on the perceived usefulness of smartphone. Also, social norms are influential variables on the perceived enjoyment of smartphone.
