The intelligent PVR(Personal Video Recorder) is an enhanced PVR that provides viewers with some advanced features as well as pause, instant replay, search and skip forward found in conventional PVRs. By embedding a home server into a PVR, it is possible for an intelligent PVR to provide a powerful web-based management user interface constructed using HTML, graphics and other features common to web-browsers. When applied to other embedded systems, web technologies offer graphical user interfaces which are user-friendly, inexpensive, cross-platform and network-ready. It is the purpose of this paper to introduce implementation of intelligent PVR which is control by internet. We present the architecture of an home- server with a simple but powerful web-based network interconnection.

Public awareness of air pollution problem has increased the need for real time air pollution information system about changes in air pollution level. The purpose of this study is to construct e-AIR, a user-friendly air pollution information system for urban air quality using GIS(geographic information system) technology for windows. GIS was ideally suited featuring a geographical characteristics(e.g., road, traffics, buildings) and very effectively used in mapping and symbolization for the distribution of the spatial/periodic pollution status(e.g., pie or column chart, graduated symbols) which can be effectively applied to a information system on the web-site. And a user interface, GUI(graphic user interface) was designed very diversely and simply enabled the users connect with e-AIR and obtain a useful information of air quality. A interpretive technique, air pollution health index(e.g., PSI, AEI) was used also which transforms complex data on measured atmospheric pollutant concentrations into a single number or set of numbers in order to make the data more understandable. Eventually the final-step of this study was to construct e-AIR based on Web GIS could be assessed anywhere if internet is available and offer a very useful information services of the air pollution to the public like a weather news.

In this paper, a web based remote control system located at too dangerous field to access for the worker. The system was designed and implemented for three-dimensional stereo camera connected to web server which can be controlled easily by client side person working in the safe monitoring room. The user in the client side can control the vergence/focus control and zoom-in/out and pan/tilt functions through an user interface. The user interface for remote control environment was designed and implemented with Java applet mechanism, and was tested the operation result of the system.

A shared work platform is needed to legitimately activate shared works. To facilitate the use of copyrighted works by streamlining licensing procedures and by expressing and distributing the scope of use by authors themselves. In this study, five interface areas and fifteen evaluation items were selected to analyze the interface types and characteristics of the Korean shared work platform, and analyzed based on the national operating platform. We will analyze and compare the situation of the web interface of the Korean shared works by analyzing the types and characteristics of the web interface of the public opera platform, the Gongu-madang, Gonggong-nuri and private leader, Europeana.

Panning tasks caused by both a small screen and the lower resolution of handheld devices are known to decrease the usability of a mobile internet service. To solve this problem, we proposed FTND, an improved version of Tap-N-Drag widely used in various mobile web browsers. 30 participants performed the panning tasks with FTND embedded in combinations of 2 panning directions of Push Background user interface and Push Viewpoint user interface and 5 panning ratios of 100% (a panning ratio of Tap- N-Drag), 300%, 500%, 700%, and 900%. The usability of FTND was assessed by an objective performance and a subjective preference. The objective performance was measured by a task completion time, the number of clicks, and the number of pixels. The subjective preference was measured by satisfaction, accuracy and ease of use. Push Viewpoint user interface at the panning ratios of 300%, 500%, and 700% proved to be the most efficient way for panning tasks with small handheld devices when performing the task by using the right hand thumb.

The enlarge the range of internet users require user centered design method what understanding of cognitive faculties about users by different age groups. This study aims at analyzing cognitive faculties about visual information on web interface by different age groups, presenting visual perception cognitive process model as an evaluation model and proposing an effective web interface design guideline, On the basis of analyzing cognitive faculties verified what each detail property of visual perception cognitive process model as form, color, space, movement and physiological, physical cognitive faculties had have individual cognitive faculties. As the result visual perception cognitive process model suggested in this study can be used as an evaluation model of web interface and users' cognitive faculties analyzed in visual perception measurement by different age groups can be applied as a web interface design guideline. In addition, this study has a meaning in that it makes a chance to extend a web designer's roles and establish a direction of future research by usability of different age groups.

This paper conceptualizes the two-faced platform based on interface studies and two-sided market theory to critically analyze today's information technology culture such as the Internet. With this conceptual framework, the Internet can be investigated to have two faces, in which the square of user's openness, sharing, and participation is unfold on the front face, whereas the market of tracking, surveillance, and control of user's activities is formed on the other face. The two faces contradictorily coexist, resulting in technological and cultural dynamics on the Internet. Therefore, the Internet today as a two-faced platform can be described as a square-market interface. By analyzing on transformation of the web architecture, shift of informational commodity from content to data, and web bugs' user tracking across two faces, it examines how the world wide web itself can function as a two-faced platform. Lastly, implications and further works are suggested to improve the two-faced platform as a conceptual framework and to deeply analyze broader information technology culture based on it.

For the development of automobile lighting components, various designers, developers and manufacturing personnel are involved, each group needing different software tools. In this Smartlite project, several software tools were developed far product development of the lighting components and then tested using two different user interfaces (UIs); the first was based on a commercial CAD system (SDRCI-DEAS) and the second was based on a web browser. The specific focus of this study was a comparison between the new web-based UIs, and the UIs on commercial CAD systems. The usability data have been collected from the users at Visteon and showed that the web-based UIs provided comparable functionality with the CAD-based UIs in terms of performance and usefulness. For the criteria of accessibility, the web-based tools out-performed the CAD-based tools.

Existing usability testing method, particularly lab-based usability testing, has been widely implemented for development of user interface. However, the method has critical disadvantages such as high cost, time and effort, unnatural testing environment, and lack of user's direct participation in information architecture. With these backgrounds, this paper aims to develop the web-based participatory tool with particular focus on card sorting. Our tool was developed for allowing user to participate in card sorting with his own computer through web. All the data generated while user is participating in the test are automatically sent to the server, which makes it very easy to collect card sorting data. Users can drag cards of interface elements directly and build the interface structure in their own from their computer-screen so that they can represent their mental models on interface structure of testing website. These functions of our tool can help designers to implement card sorting without tedious and time consuming procedures and improve the method of usability testing by reinforcing user's active participation in building an information architecture.
