As the propagation of smart devices has increased and the variety of the devices also has been diversified, various existing functions are concentrated on these smart devices. One of the phenomena is that the paper-book market has partially transferred into an e-Book market. As the demand of the e-Book has increased over time, the improvement of the types of e-Book on the market can be observed. In this study, the usability evaluation on the interface of the e-Book viewer for the types of application, which can be installed in the smart devices, has been conducted. The items for the usability evaluation of the e-Book were defined, the usage patterns were observed objectively and a questionnaire technique was applied. By analyzing the usability evaluation of e-Book interface, the directions for production and improvement of e-Books have been suggested.

The purpose of this study is to explore physical factor of digital text structure for designing e-Book interface and to develop prototype of e-Book interface by applied these factors. To address this goal, explore factor analysis and confirmatory factor analysis were employed, 237 university students were the participated in this study. According to a result, 29 items for physical feature of digital text structure were developed, 9 factors of digital text structure were also extracted; volume, depth, density, space, layout, format, signal, size, and length. Besides, to identify structure of pre-defined 9 factors, confirmatory factor analysis was conducted. As a result of CFA, the factor structure was supported by all of model fit indices.

In this paper, we proposed a tangible RealBook based on the interface of TouchFace-V which is able to recognize multi-touch and hand gesture. The TouchFace-V is applied projection technology on a flat surface such as table, without constraint of space. The system's configuration is addressed installation, calibration, and portability issues that are most existing front-projected vision-based tabletop display. It can provide hand touch and gesture applying computer vision by adopting tracking technology without sensor and traditional input device. The RealBook deals with the combination of each advantage of analog sensibility on texts and multimedia effects of e-book. Also, it provides digitally created stories that would differ in experiences and environments with interacting users' choices on the interface of the book. We proposed e-book that is new concept of electronic book; named RealBook, different from existing and TouchFace-V interface, which can provide more direct viewing, natural and intuitive interactions with hand touch and gesture.

Electronic Book(eBook) is a publication that stored and processed the contents of a book using digital mechanisms and has advantages such as easiness in saving and searching and the possibility of carrying. To activate Electronic Book which has the advantages mentioned above, studies on related techniques are required and a development of an editor exclusive for eBooks which is appropriate for eBook structure is still not adequate. In this paper, we design and implement Electronic Book editor providing form-based interface for eBook genre-based structure so that it would be easier for users to write. Especially because Electronic Book has genre-based structure due to the characteristic of literature, it is necessary to provide forms for each different genres. Therefore, compared to the problem of having to study XML grammar when writing Electronic Book using the existing XML editor, the proposed system can solve this problem by providing form-based interface. Additionally, with regard to the characteristic of eBook which have structures according to the intention of users, we provided the flexibility of adding dynamic forms to the form provided in default so that it will be more effective in writing Electronic Books. Therefore by providing form-based interface according to the genre and dynamic structure according to the intention of users, Electronic Book can be wrote more easily.

As the eBook market grows fast recently, various eBook viewer solutions such as hardware viewers and software readers came out to the market. We can, however, hardly find mobile eBook interfaces for the reading disabled people who have difficulties in reading for their visual impairment or learning disabilities, or dyslexia. An eBook viewer interfaces for the reading disabled people should be carefully and distinctively designed because the reading disabled people cannot use normal versions of eBook viewer. In this paper, we suggest a eBook viewer interface model to make the reading disabled people read eBooks easily. Depending on the type of the reading disabled people: the full blind, the almost blind, the just learning disabled, our model provides an adaptive interface to make them read eBooks effectively. In addition, unlike the existing simple audio books, we also support annotation systems to make the reading disabled people interact with eBook viewer. To show the effectiveness of our model, we implemented an eBook viewer prototype on an android-based mobile device. We are sure that our model and implementation can make the reading disabled people, who is 10% of all the domestic people, read eBooks effectively.

In this paper, we propose user-centric immersible and interactive electronic book based on the interface of tabletop display. Electronic book is usually used for users that want to read the text book with multimedia contents like video, audio, animation and etc. It is based on tabletop display platform then the conventional input device like keyboard and mouse is not essentially needed. Users can interact with the contents based on the gestures defined for the interface of tabletop display using hand finger touches then it gives superior and effective interface for users to use the electronic book interestingly. This interface supports multiple users then it gives more diverse effects on the conventional electronic contents just made for one user. In this paper our method gives new way for the conventional electronics book and it can define the user-centric gestures and help users to interact with the book easily. We expect our method can be utilized for many edutainment contents.

Many e-book readers have become available as e-books are in popular use these days. We first developed the evaluation criteria and elements for testing the usability of e-book readers and then examined the usability of three e-book readers. The usability testing was conducted using three e-book readers that were most popular with 15 participants that consisted of middle school students, university students, and office workers. The study found that iPad showed the best usability. In case of Amazon Kindle, participants indicated that the lack of the touch function imposed a great deal of negative impact on the usability of the interface. Also, the hardware- and software-oriented usability provided by an e-book reader was considered to be a very important element for the users, and the portability in connection with the hardware-oriented aspect of an e-book reader was shown to be of great effect to the overall usability of an e-book reader.
