In this paper, we propose layout based multimodal contents authoring tool for Digilog Book. In authoring step, users create a virtual area using mouse or pen-type device and select property of the area repetitively. After finishing authoring step, system recognizes printed page number and generate page layout including areas and property information. Page layout is represented as a scene graph and stored as XML format. Digilog Book viewer loads stored page layout and analyze properties then augment virtual contents or execute functions based on area. Users can author visual and auditory contents easily by using hybrid interface. In AR environment, system provides area templates in order to help creating area. In addition, proposed authoring tool separates page recognition module from page tracking module. So, it is possible to author many pages using only single marker. As a result of experiment, we showed proposed authoring tool has reasonable performance time in AR environment. We expect that proposed authoring tool would be applicable to many fields such as education and publication.

Fashion companies are increasingly becoming aware of the importance of Digilog as a response strategy to an emotional stimulus, in order to win the hearts of consumers, because the Digilog provides a new type of emotional value. The features of Digilog found in modern fashion are characterized as follows: first, the "Fashion Image of Hybrid Nature" expresses nature in a new light or reinterprets existing expressions of nature, by using cutting-edge technology based on the psychological desire to return to, adapt with, and harmonize with nature. Second, the "Fashion Image of Nostalgia," which exhibits past forms of regressive fashion, is a fashion code that can be understood as a social trend. It has a digital exterior, with retro materials and old perfumes that reflect psychological comfort, as its expressive medium. Third, the "Lifestyle through the Technique of Interaction" is the sharing of information through consumer participation and delivery, or its interaction. Fourth, the "Fashion Design through the Technique of Customizing" allows consumers to actively participate in the design process. It reflects the consumer's desire to personally design fashion products. Fifth, the "Emotion Sharing through the Technique of Storytelling," which focuses on intangible values, is based on the sentiment of communication between the consumer and the brand, thereby satisfying the inner values as well as the aesthetic demands of consumers. This study confirmed that digital fashion, which uses digital technology based on analog sentiments, has opened up a new environment for fashion culture and has also widened the boundaries of fashion.

A Digilog Book is an augmented reality (AR) based next generation publication supporting both sentimental analog emotions and digitized multi-sensory feedbacks by combining a conventional printed book and digital contents. As a Digilog Book authoring software, ARtalet provides an intuitive authoring environment through 3D user interface in AR environment. In this paper, we suggest ARtalet authoring environment based trajectory editing method to generate and manipulate a movement path of an augmented 3D object on the Digilog Book. Specifically, the translation points of the 3D manipulation prop is examined to determine that the point is a proper control point of a trajectory. Then the interpolation using splines is conducted to reconstruct the trajectory with smoothed form. The dynamic score based selection method is also exploited to effectively select small and dense control points of the trajectory. In an experimental evaluation our method took the same time and generated a similar amount of errors as the usual approach, but reduced the number of control points needed by over 90%. The reduced number of control points can properly reconstruct a movement path and drastically decrease the number of control point selections required for movement path modification. For control manipulation, the task completion time was reduced and there was less hand movement needed than with conventional method. Our method can be applicable to drawing or curve editing method in immersive In-Situ AR based education, game, design, animation, simulation application domains.

'Digilog Book' integrates advantages of existing paper book and immersive digital contents in augmented reality environment, which enables users to feel physical touch and get additional multisensory feedback. As a high level authoring user interface, 'ARtalet' provides an intuitive way to make Digilog Book through 3D user interface in augmented reality environment. This paper mentions trajectory inserting and editing methods of 3D objects, then combining method of the trajectory. 3D object is selected by camera tracked prop, and then transformation matrix relative to book plane is stored in real time based on timeframe. The saved trajectory is managed as templates, and user can make various compositions of trajectories. We expect that suggested methods can enhance interest of readers.

Digilog Book, the next generation publication material, supplies digitalized contents on an analog book by integrating digital contents into existing analog books. There are some studies related to authoring tools which are to authorize, and publish some books which provide digital contents by using VR or AR techniques. In this paper, a pen-type haptic user interface for Digilog Book authoring tool has been introduced. This haptic user interface is developed for more realistic and more effective authoring tasks. This haptic interface provides haptic effects for authoring tasks which are including translation, rotation, scaling, and menu selection. In this research, we designed a body, control circuits, vibration haptic patterns for haptic user interface, and a protocol for between haptic user interface and Digilog Book main control system. Also a simple user study has been done with a developed haptic user interface.

Recently, the government as part of the creation of science for science education policies promoting the activation of the Science Museum. However the lack of infrastructure, budget and human resources are a reality that a lot of difficulties. In past, A field trip of Science Museum was a place of curiosity of youth. However, modern Science Museum has to competition with the online games and theme park in order to achieve the two goals of scientific experience and education, which it needs change display device is required. Looking at the cases of advanced foreign Science Museum is not merely a head of science education experience as a cultural space, provide relaxation and entertainment, and life science area in addition to a variety of genres such as art and fashion exhibits are planning to combine. In this study, the current uniform description panel of exhibition device described in the written text replaced with the digilog book with the age and grade of the visitors by providing a tailored service for scientific knowledge and intellectual curiosity induced measures can claim the satisfaction of visitors is proposed.

Many AR (Augmented Reality) applications have been interested in a marker-less tracking since the tracking methods give camera poses without attaching explicit markers. In this paper, we propose a new marker-less page recognition and tracking algorithm for an AR book application such as DigilogBook. The proposed method only requires orthogonal images of pages, which need not to be trained for a long time, and the algorithm works in real-time. The page recognition is done in two steps by using SIFT (Scale Invariant Feature Transform) descriptors and the comparison evaluation function. And also, the method provides real-time tracking with 25fps ~ 30fps by separating the page recognition and the frame-to-frame matching into two multi-cores. The proposed algorithm will be extended to various AR applications that require multiple objects tracking.

This paper is about an authoring interface for augmented/mixed reality based book, specifically authoring 3D objects properties of Digilog book. We pursue even normal users with non-professional knowledge for programming can make the Digilog book easily. An authoring interface 3D object properties includes a manipulator as an input device and 3D contents authoring parts. As an interface design metaphor, existing GUI interface, already familiar to computer users, are referenced. The manipulator generates continuous/discrete input signal are necessary for authoring interface. Contents authoring part performs selection, positioning, scaling, coloring, copy of virtual objects using the input signal of the manipulator. Also users can exploit already existing GUI interface metaphor including pointing, click, drag and drop, and copy techniques with the manipulator. Therefore we think our AR authoring system can support rapid and intuitive modification of properties of virtual objects.
