In this paper, we propose a human-content interface that allows users to quickly and efficiently search data through friction-based scrolling with ROI(Regions of interests). Our approach, conceived from the behavior of finding information or content of interest to users, efficiently calculates ROI for a given content. Based on the kernel developed by conceiving from GMM(Gaussian mixture model), information is searched by moving the screen smoothly and quickly to the location of the information of interest to the user. In this paper, linear interpolation is applied to make one softer inertia, and this is applied to scrolls. As a result, unlike the existing approach in which information is searched according to the user's input, our method can more easily and intuitively find information or content that the user is interested in through friction-based scrolling. For this reason, the user can save search time.

The purpose of this paper is to suggest a method that .NET smart web development is enhanced through Managed Hybrid Web to improve the problems of UI development and representation in Hybrid Web. Improvement of structured system design of Managed Hybrid Web can enhance the efficiency and extendability of the interface objects. In particular, Source convenience is further enhanced regarding to coexistence of the objects if a client and server technique is applied to the class generation ways. It comes to the conclusion that the application of the user interface has the free representation ways, and the extension of representation ways can be achieved by each part independence.

This paper proposes and implements a mobile service and web service integration for utilizing public bicycle sharing system NUBIJA. The NUBIJA system is operated by Changwon City, GyeongNam since 2008 and maintains 247 unattended bicycle sharing terminal on the city. Average users per day of the NUBIJA are more than 8,000 and many users want to get more services from their mobile phones. We implemented realtime mobile bicycle rental and return information service. The informations are acquired from each terminal kiosks and we integrated the information and location based services(LBS) on iOS and Android platform. In this paper, we described an integration services between web and mobile application and shows graphical user interface for highly customized on mobile platforms.

A new cultivation diary system based on environment sensor data and Web 2.0 with Flex is suggested, to improve the previous system using the subjective data of cultivators. The proposed system is designed by applying an object-oriented model called mini-architecture, in order to enhance the reliability of software as well as promote stability to overall system design. The environment sensor data such as temperature and humidity are used to develop the new reliable diary. Also, an active interface based on Web 2.0 and Android as the user GUI are implemented to maximize the convenience while recording the cultivation diary. The result of the performance evaluation shows that the data from sensors has 99.1% of correlation with that of analogue.

With development of computer engineering and the examination theories, new techniques to use computers in making or administrating examinations had been studied and developed. Recently, studies on web-based testing are in progress with development of Internet and information and communication technology. However, as compared with development of these technical aspects, studies on the user legibility to provide learners with comfortable environment for the evaluation have been insufficient in fact. In the web-based testing, user legibility decreases the anxiety of examinees in the examination and plays an important role in measuring their competence exactly. In this study, we tried to provide the optimum web-based evaluation interface by obtaining information through a questionnaire for primary-school students. We think that principles suggested in this study can give a great help in making the web-based evaluation screen in future. Besides, studies on more various fields including making individual questions, instructing sentences and layout of multimedia factors as well as the principles mentioned in this study should be performed.

Compared to the existing PC which uses a mouse and a keyboard, the touchscreen-based portable PC allows the user to use fingers, requiring new operation methods. However, current touchscreen-based web browser operations in many cases involve merely having fingers move simply like a mouse and click, or not corresponding well to the user's sensitivity and the structure of one's index finger, making itself difficult to be used during walking. Therefore, the goal of this study is to develop finger gestures which facilitate the interaction between the interface and the user, and make the operation easier. First, based on the frequency of usage in the web browser and preference, top eight functions were extracted. Then, the users' structural knowledge was visualized through sketch maps, and the finger gestures which were applicable in touchscreens were derived through the Meaning in Mediated Action method. For the front/back page, and up/down scroll functions, directional gestures were derived, and for the window closure, refresh, home and print functions, letter-type and icon-type gestures were drawn. A validation experiment was performed to compare the performance between existing operation methods and the proposed one in terms of execution time, error rate, and preference, and as a result, directional gestures and letter-type gestures showed better performance than the existing methods. These results suggest that not only during the operation of touchscreen-based web browser in portable PC but also during the operation of telematics-related functions in automobile, PDA and so on, the new gestures can be used to make operation easier and faster.

Most Hospitals develop a Medical online appointment system for u-Hospital which system based on Web Application. Web 2.0 technology has good user interface and fast response time in a web service. This paper proposed a Mobile Medical Online Appointment System using Web 2.0 Technology. This system improve the page view, convenient UI and fast response time. We test this system with evermedi, other hospital system in iwebtools service and show that it can improve the efficiency and perfomance. The proposed technology can improve the efficient mobile service because it can be extended to ubiquitous mobile application.

In this paper, we have designed and implemented lamp control system in underground parking place using WWW. The proposed system consists of lamp control system which is connected by RS-485 communication bus and monitoring system (WebPL) which can provide web interface using the web server. The lamp control system is controlled through a user command within the monitoring system (WebPL), senses moving object and turns lamps in underground parking place on or off. The monitoring system displays the status values of on or off received from lamp control system on the web browser and can real-timely control lamps in underground parking place on the web browser.

IoT is the foundation technology that the things share the information through connected with Internet to provide service based on these information. It is applied to various fields such as personal, public and industry. Therefore, the service development is required to meet the requirement of the various service environments. The IoT service environment will be developed as the participation IoT service environment which increase the value and efficiency such as the Broadcasting and web services changed from the service provider environment to the user participation service. The user can directly reflect their requirements using the user participation IoT service environment. So, the types of IoT services will diverse and accelerate the spread of IoT service. In this paper, we derive the IoT service element through the analysis of various service scenarios, and propose the participation IoT service model and modeling mechanism. It provides the sequential service model and the relation based service model according to the service modeling proficiency of user. The proposed environment provides the web-based user interface that is implemented by the participation IoT service brokering platform.
