Recently, as the importance of mobile marketing is emphasized, the in-app advertising market, which inserts ads into applications, is growing. The purpose of this study is to verify the interaction effects of need for cognition, contextual consistency, and product involvement on advertising attitude. The experimental design of this study is a three-way mixed design of 2 (consumer need for cognition: high vs low) × 2 (contextual consistency: context match vs context mismatch) × 2 (product involvement: high vs low). The subjects of the survey were 337 men and women in their 20s and 30s Living in Seoul and Gyeonggi-do. SPSS 25.0 statistical program was used to analyze frequency analysis, reliability analysis, t-test, three-way ANOVA, and simple main effect analysis. The analysis results are as follows. First, contextual consistency of mobile fashion ads showed significant effect on advertising attitude. Second, consumer need for cognition and contextual consistency of mobile fashion ads showed significant interaction effect on advertising attitude. Third, contextual consistency of mobile fashion ads and product involvement showed significant interaction effect on advertising attitude. Finally, product involvement and consumer need for cognition showed a significant interaction effect on advertising attitude. Based on the research results, it will help fashion companies to establish effective mobile in-app advertising strategies.

A rectangle-based relative localization method is proposed for a mobile robot based on a novel geometric formulation. In an artificial environment where a mobile robot navigates, rectangular shapes are ubiquitous. When a scene rectangle is captured using a camera attached to a mobile robot, localization can be performed and described in the relative coordinates of the scene rectangle. Especially, our method works with a single image for a scene rectangle whose aspect ratio is not known. Moreover, a camera calibration is unnecessary with an assumption of the pinhole camera model. The proposed method is largely based on the theory of coupled line cameras (CLC), which provides a basis for efficient computation with analytic solutions and intuitive geometric interpretation. We introduce the fundamentals of CLC and describe the proposed method with some experimental results in simulation environment.

As mobile shopping has been increasing, the competition has been also increasing to satisfy various consumers' needs. Despite such increase in terms of the volume of the consumers who use mobile shopping, there has been very few studies to examine characteristics of mobile shopping malls. The purpose of this empirical study is to investigate the effect of characteristics of mobile shopping malls on consumer loyalty and the interaction effect of the O2O experience on the relationship between the characteristics of mobile shopping malls and consumer loyalty. Using a sample of 276 individuals who have experienced mobile shopping, we found that certain characteristics such as ubiquity, personalization, or convenience have a positive impact on consumer loyalty and a design characteristic solely has an interaction effect on consumer loyalty. As consumer loyalty has a critical factor on mobile shopping mall's profit, examining which factor has a positive effect on consumer loyalty is beneficial for mobile shopping malls. The results of the study have both practical and empirical implications.

실시간 소셜(Social) 네트워킹 서비스를 위해서, 사용 가능한-통합적-유비쿼터스 (U3) 웹 서비스에서의 모바일 상호작용을 연구하였다. 실시간 소셜 네트워크를 위한 편리한 모바일 HCI로서, 또한 유비쿼터스 웹 서비스에서의 메타데이터 정보 색인 키로서, 다국어 한 글자 도메인 명(예, 김.net, 이.net, 가.net, ㄱ.net, ㄴ.net, ㅎ.net, ㅏ.net, ㅔ.net, ㄱ.com, ㅎ.com) 은 소셜 정보를 검색하고 또한 등록할 때 편리한 모바일 인터페이스이다. U3 웹 서비스의 예로서, 실시간 소셜 네트워킹 서비스 구현과 함께 모바일 상호작용을 위해 스케치된 디자인 목표와 한국, 일본, 중국에서의 모바일 상호작용 경험을 소개한다. 또한, 소셜 네트워킹과 센서 네트워킹 서비스에서 통합 정보관리를 위해, IP 기반의 센서네트워크 (IP-USN)에서 메타데이터 디렉터리 서비스에의 응용 확장 가능성도 소개한다.

본 연구의 목적은 성공적인 모바일 소셜네트워크 게임(SNG)을 제작하기 위해 게임의 세부 콘텐츠를 어떤 목적으로 제작해야 하고 어떤 부분에 보다 많이 집중하여 제작해야 하는가에 대한 가이드라인을 제시하는 것이다. 모바일 SNG의 제작목적을 지속적 사용의도의 향상으로 설정하였으며, 선행연구에서 이에 영향을 주는 것으로 실증된 요인들 중 몰입, 사회적 상호작용, 자기효능감, 경쟁, 보상의 요인을 선별하였다. 최종적으로 사회적 상호작용, 자기효능감, 경쟁, 보상에 관련된 사용자 경험의 향상을 모바일 SNG 세부 콘텐츠의 제작목표로 설정하여 연구를 설계하였다. 강원도의 한 대학교에서 모바일 SNG 사용경험이 있는 대학생들을 대상으로 3주간에 걸쳐 설문조사를 수행하였고, 총 244부를 분석대상으로 사용하였다. 분석방법은 SPSS 18.0을 활용한 위계적 회귀분석이었으며, 본 연구의 결과로 자기효능감, 보상, 경쟁, 사회적 상호작용에 관련된 사용자 경험의 향상을 목표로 하는 콘텐츠들이 모두 지속적 사용의도의 향상에 유의미한 영향을 미친다는 것과 그 영향력의 차이를 확인할 수 있었다.

User enjoyment is a key factor to understand online and mobile game users' behaviors. This study aims to understand the differences between mobile and online games, and the differences between Korean and Chinese game users in terms of the perceived importance of user enjoyment elements. To use AHP (Analytic Hierarchical Process), we decompose user enjoyment into sub-elements; sensory enjoyment, content enjoyment, enjoyment of the achievement, and enjoyment of interaction. Though the empirical study and independent t-test, we can find that there are the differences in the perceived importance of user enjoyment elements between Korean and Chinese game players, and between mobile and online games. Chinese users more stress on enjoyment of interaction and Korean users more emphasize on enjoyment of the achievement.

This paper presents the position-based force control application of a mobile manipulator. The mobile manipulator consists of two six DOF manipulators and a mobile robot. Kinematics of the robot is analyzed and simulated to validate the analysis. A position-based force control technique is applied to the robot by adding an outer loop to interact with the environment. Experimental studies of force control applications of robot arm and interaction with a human operator are conducted. Experimental results show that the robot arm is well regulated to follow the desired force.

A touchless user interface system is proposed for real-time mobile devices in this work. The proposed system first recognizes the position of pattern to interact various applications based on the scene taken from mobile camera. Then, the proposed system traces the route of the pattern, which estimates the motion of pattern based on the mean-shift method. Based on this information, we control menu and keypad for the various applications. Differ from other user interface systems, the proposed system provides the new experience to even for the user of low-end mobile without additional hardware. Simulation results demonstrate that the proposed algorithm provides better interaction performances than the conventional method, while achieving real-time user interacting for mobile devices.
