E-books have been popular and common in everyday life during past a decade, and the market is expected to grow much more because of the popularity of tablet computing devices such as iPad. With the helps from the devices, people want to read or experience more interactive, fun, and informative e-book contents. In order to meet those needs, we introduce requirements of an e-book viewer system that supports user interaction, 3D modeling view, and augmented reality. We also introduce some design issues of the system and its concept proof prototype system. We determine to adopt HTML5 for e-book content format because it already supports content rendering, multimedia, and user interaction. Furthermore, it is easy to implement e-book viewer because there is already Webkit component for HTML5. We also discuss design issues for integrating an Augmented Reality viewer with Webkit-based e-book viewer. This paper will give e-book viewer developers and contents developers some guidelines for new e-book systems.

The DAISY, an international digital talking book standard, has been established to help reading-disabled people read books normally. As many societies' interests in reading-disabled people are arising, reading environment for them is also getting improved by supplying alternative books. In the digital world, however, there is still lack of e-book playing software for them. In this paper, we design and partially implement an android smartphone e-book viewer. By analyzing the features and relations of DAISY3 files, we can find several important design points to properly implement DAISY3 viewer. We are sure, when using our results, that various DAISY3-compliant e-book viewers can be implemented easily and quickly.

Early, national basic topographical map has been represented, stored, supplied in form of DXF(Data eXchange Format) and present digital map is equipped as over form. Since many parts of digital map has been equipped newly to use early digital map form for geographic information system. Especially, many structural editing and geographical search are demanded to exclude geometric inconsistency and logical inconsistency included in the existing digital map. As above, DXF is unsuitable data format to use in geographic information system. For the sake of efficient format, Digital Map Ver. 2.0 that is new map format was developed. In this study, we developed the Mobile Viewer program development which can let us see immediately the digital maps produced in the form of Digital Map Ver. 2.0.

The study was designed to transmit ECG(electrocardiogram) images from iPhone in order to check validity. Especially, web examined ECG transmissions from smart phones image viewer are good enough to secure clinical information and confirmed with visual. In result, it took 3 to 5 seconds for ECG viewer transmitting from a smart phone to display an image on mobile server to user's phone. For image valuation, we magnified the ECG image 100% or 200% at a resolution of $480{\times}320$ checking PQRST wave and found that it was both possible to see an accurate PQRST wave with all the trial data and to divide it into 1mm level of grid.

Due to the development of the digital technology, the digital broadcasting is changing to a multi-entertainment platform that can operate data (broadcasting) services (such as games, weather information, and stock trading services) as well as traditional broadcasting contents. Most of the data services, however, failed to get satisfactory results because of the inconvenience in operating the services using a TV remote controller and the failure of gaining the viewer's interests in the competition with the broadcasting contents. The paper introduces a survey on the viewer's modality of using a data service and, based on the survey result, proposes a design guideline that makes a data service minimally interrupt a viewer watching a broadcasting content.

Due to the high digital technology, various devices such as TV, PC, smartphone, and pad computer are connected to each other using internet and under the circumstance internet services of which the running platforms are mainly PC become "N-screenlized" by extending their service platform to non-PC devices. As a digital TV has outstanding features of being the most influential device in the living room and having the wide spectrum of users, several internet services has been ported on the digital TV platform (in the form of data services) in order to enhance their brand powers. Most of the services, however, failed to get a satisfactory results as the data services are defeated by the broadcasting contents in the competition for the viewer's interests. In the paper, the design guidelines that make data services not to compete with the broadcasting contents are proposed and a prototype of a data service that accommodates the guidelines is introduced. The prototype, called "TV ideal-type world-cup", does not disturb a viewer's watching broadcast contents and channel-changing behavior while it is running and its service flow is designed for a viewer to achieve the goal of service in a few minutes so that the viewer can enjoy the service in a commercial period.

With the rapid progress of medical image information system, a variety of researches for the system that can read and decipher the medical images in anytime and anywhere have been studied. In this paper, we develop personal digital assistant (PDA) device based mobile digital imaging and communications in medicine (DICOM) image viewer that can process the received medical images at any time. In particular, with the aid of the proposed mobile DICOM image viewer, we can read several images simultaneously and we can read the selected image only from the several images. To cope with the small size of PDA screen, the function of image enlargement is also included in the proposed mobile DICOM image viewer.

e-book is digital contents using IT technology instead of paper. It is carried in Internet and displayed wish Viewer of PC, PDA or terminal. The Open eBook specification is to provide a specification for representing the content of electronic books to these viewers. The specification is based on HTML and XML, the same core languages that define the World Wide Web, and is designed to allow publishers and authors to deliver their material in a single format. In this paper, we design and implement the viewer that can support OEB(Open eBook) standard. Viewer is composed parser part and display part. In audition, we add some functions - the book shelf, the bookmark and the dictionary - for convenience of readers.

TV broadcasting platform is evolving to the digital-TV, which is supporting data broadcasting service. Although the data broadcasting services (i.e., games, wether information, stock trading service) provide rich entertainment to viewers, they make the operation manners of digital-TV so complex that some viewers feel difficulty in using their TV sets. The paper tackles the problem by devising a method for constructing viewer-specific EPG configurations based on the viewers' ability of handling IT devices. The paper also propose an environment (e.g., EPG configuration transmitting method, EPG structure) that implements dynamically an EPG configuration based on the viewer's choice of EPG configuration.

Because of today's rapid growth of digital contents market and many benefits of electronic book, many people have considerable interest in E-book. Furthermore multifarious consortiums take an active part in standardization of I-book, and many E-book tools have been provided by software manufactures all over the world. E-book tools include editor for production of E-Book, viewer for reading, and the like. Especially in E-book viewer, annotation function has to be Included to put arrangement, summation, recording, comment, emphasis and after comprehension to practical use. In this paper, a E-book viewer with annotation is designed according to the specifications of EBKS, Korean standard. The proposed viewer is aimed to implement in PDA with embedded Linux, but developed in Windows 2000 platform. Because development environment and application environment are different each other, Qt-Library and cross-compiler are used for cross-platform development. The viewer support various functions such as adjusting of font size, hypertext linking, retrieval of specific word, and so forth. And in addition to these basic functions, annotation function is designed for the viewer, which can be used for re-usage and sharing of important information.
