In this paper, we propose a user interface technique based on embedded sensors applying to apps in smart phone. Especially, we implement avata generation application using image filtering technique for photo image in smart phone. In the application, The embedded sensors are used as intuitive user interface to adjust the image filtering effect for making user satisfied effect in real time after the system produced the image filtering effect for avatar. This technique provides not a simple typed method of parameter values adjustment but a new intuitively emotional adjustment method in image filtering applications. The proposed technique can use sound values from embedded mike sensor for adjusting key values of sketch filter effect if the smart phone user produces sound. Similiarly the proposed technique can use coordinate values from embedded acceleration sensor for adjusting masking values of oil painting filter effect and use brightness values from embedded light sensor for adjusting masking values of sharp filter effect. Finally, we implement image filtering application and evaluate efficiency and effectiveness for the proposed technique.

The main objective of this paper is analyzing the effects of task uncertainty on EUC characteristics and end user satisfaction. Task uncertainty were identified as an important determinant of EUC characteristics. And the moderating effect of task uncertainty on the relationship between EUC characteristics and end user satisfaction was suggested. A field study was undertaken to test the hypothesized relationships among task uncertainty, EUC characteristics, and end user satisfaction Data were collected from 138 end-user of 19 Korean business organizations. The empirical results indicated that task uncertainty was significantly related to EUC characteristics and that task uncertainty had significant effect on the relationship between EUC characteristics and end user satisfaction. Implications and future research directions are drawn for the management of EUC and for further research on EUC.

본 연구는 스마트폰의 사용자경험 요소가 고객의 만족에 미치는 영향을 연구하였다. 사용자 경험요인은 선행연구를 바탕으로 유용성, 사용성, 감성, 브랜드 이미지로 하였고, 연구대상은 S사의 스마트폰 사용자 97명과 A사의 스마트폰 사용자 94명을 대상으로 하였다. 연구결과 스마트폰의 사용자 경험이 만족에 미치는 영향은 유용성 44.0%, 브랜드 이미지가 26.2%, 감성이 19.6%, 사용성이 17.3%의 영향을 미치는 것으로 나타났다. 유용성과 감성은 기술디자인의 핵심적인 요소로서 사용자지향의 설계에 중점을 두었을 때 만족을 높일 수 있다는 점에서 스마트폰 관련 설계자들이 가장 고려해야할 사항이라 할 것이다. 이러한 관점에서 S사 제품의 감성적 측면이 만족에 영향을 미치지 않고 있다는 것은 개선이 시급하다고 하겠다.

The purposes of this study were 1) to analyze the effect of the ERP quality (system quality, information quality, service quality) on the performance (end user satisfaction, user's performance, system utilization) of business, 2) to conduct the causal-effect analysis between outcome variables (user's satisfaction, user's performance, system utilization) of ERP in the contract foodservice management company. The questionnaires were distributed to 260 end users (dietitians, foodservice management managers) in charge of managing the institutional foodservice such as the office (government agencies, factories), schools (universities, middle and high school) and hospitals which were managed by contract foodservice management company 'C' in Seoul and Kyunggi. The surveys were performed from July 26, 2004 to July 30. 2004. Two hundred and fifty (250) questionnaires were responded (response rate: 96.2%). The statistical analysis was conducted using SPSS Win (11.5). And the descriptive analysis, factor analysis, reliability test, pearson correlation, simple and multiple regression analysis were performed. The results showed that among the 3 factors (system quality, information quality, service quality), the system quality and information quality were proved to have an effect on the user's satisfaction and user's performance significantly (p < .05). The influence of ERP quality (system quality, information quality, service quality) on system utilization were testified to be statistically significant (p < .05). The user's performance were affected significantly by system utilization (p < 0.001) and end user's satisfaction (p < 0.001). As a conclusion, to improve user satisfaction, which is the ultimate performance variable of an ERP system, high quality of an ERP system is the pre-requisite. And the user satisfaction and performance of business would be higher with the better quality ERP system. When constructing ERP system for the contract foodservice management company, we should improve system utilization and user satisfaction altogether so that user's performance could be ultimately enhanced and we should make efforts to enhance the quality level of ERP.

본 논문에서는 웹 접근성을 고려한 유저 인터페이스 효과를 jQuery로 구현하는 방법은 제안하였다. jQuery는 세계에서 가장 많이 사용하고 확장하기 편한 자바스크립트 라이브러리이다. jQuery는 DOM(Document Object Model)과 이벤트, Ajax의 제어에 적합하지만 고급 효과를 나타내기에는 부족한 부분이 있다. 이를 보완하고 UI(User Interface) 효과를 쉽게 적용할 수 있는 방법을 제시한다.
