  • This paper introduces a difference between mobile Augmented Reality (AR) authoring and desktop AR authoring, and suggests an interface system that can be applied to in-situ authoring of AR contents on a mobile device. The mobile devices have enabled users to use the AR system anytime and anywhere. It is now necessary to create user's individualized context information using mobile devices on the spot. To author AR contents easily with mobile devices, we need to maximize the convenience of mobile systems, which have yet limitation. To do so, this paper suggests new interaction approaches that manage augmented contents using visual cues and other simple attribute settings. In addition, to solve the problem that users have to hold their mobile devices to track markers while authoring contents, this system enables users to author contents in environment based on captured images. This interface system also can make cooperation environment for more than one users to author contents. This paper verifies the usefulness of the proposed interface by user tests. The results of an analyzing users' comments show that the proposed interface is suitable for in-situ mobile authoring system.

  • Recently, construction of infrastructure for mobile internet has been progressed very rapidly including various mobile terminals. Therefore, many service models on mobile internet have been appeared and the methods to reuse the existing huge wired web contents have been studied with many-sided ways. In this paper we classify the related technologies published up to now and make a comparison among their strengths and weaknesses, For this purpose, Technologies are classified according to authoring time, authoring place, and processing level of contents. The automatic contents re-authoring technology is examined in particular and we propose a new contents re-authoring method in which the function of compressing selected information is added in order to complement the existing contents re-authoring methods.

  • Recently, research started to focus on Digital Multimedia Broadcasting(DMB), while the DMB service is already being launched to provide high quality audio, video and data broadcasting in Korea. Therefore, the demand for multimedia contents is also rose very sharply. In this paper, we introduced an MPEG-4 contents authoring system with mobile device for Digital Multimedia Broadcasting. Our system allows both single-handed and collaborative authoring modo. Further more, to overcome the delaytime for decoding the BIFS information, we also introduced an efficient algorithm to generate dynamic and light BIFS information.

  • MPEG 4 Part 20 LASeR (ISO/IEC 14496 20) is a specification designed to deliver rich media services in a mobile environment. The specification is an emerging standard that can replace the MPEG 4 BIFS specification designed to deliver PC based heavyweight media contents. The specification describes the representation of scene information in a resource constrained mobile environment. Unlike the BIFS standard designed to deliver heavyweight rich media, the LASeR specification has a restricted description that conforms to the SVG Tiny 1.2 specification. Also, the specification has an advantage of allowing for the efficient conversion of one graphics format to another. In this paper, we present the design and the implementation of a LASeR authoring system that allows for fast and efficient creation of interactive rich media contents in a mobile environment. The Gill interface of the authoring system presented in this paper allows users, who do not have prior knowledge of the scene description language, to conveniently create contents and store the produced scenes using the internal list data structure. The system allows users to navigate scene objects internally stored and to create LASeR XML files in the structured XML format.

  • In this paper, we developed an interactive animation authoring tool and developed the Android based interactive edutainment contents. The authoring tool for creating interactive animations developed in this paper is based on a graphical user interface, so users can easily create interactive animations. Interactive animation contents created by this authoring tool can be created as images and xml files so that they can be used directly on mobile devices. In order to increase learning efficiency for children, Android-based interactive edutainment electronic storybooks, which is implemented using this authoring tool, provided a recording function to listen to the parents' voice as well as an interactive action in which the characters move in accordance with the story line. We also provided a STEAM game that combines creativity and imagination with creative science and technology. Therefore, by creating the edutainment contents through the proposed authoring tool for interactive animation, various interactive animation contents could be produced more easily than the code implementation method. Through this study, I hope that it will be helpful for the development of various interactive edutainment contents to provide educational contents considering the quantity and quality to infants.

  • Since affective computing has been introduced in 90s, affect recognition technology has achieved substantial progress recently. However, the application of user emotion recognition into software user interface is in its early stages. In this paper, we describe a new approach for developing mobile user interface which could react differently depending on user emotion states. First, an emotion reaction model is presented which determines user interface reactions for each emotional state. We introduce a pair of mappings from user states to different user interface versions. The reacting versions are implemented by a set of variations for a view. Further, we present an authoring framework to help developers/designers to create emotion-aware reactions based on the proposed emotion reaction model. The authoring framework is necessary to alleviate the burden of creating and handling multi versions for views at the development process. A prototype implementation is presented as an extension of the existing authoring tool DAT4UX. Moreover, a proof-of-concept application featuring an emotion-aware interface is developed using the tool.

  • In this study, an integrated 3D modeling and rendering system dealing with 3D urban landscape features such as terrain, building, road and user-defined geometric ones was designed and implemented using $OPENGL\;{|}\;ES$ (Embedded System) API for mobile devices of PDA. In this system, the authoring functions are composed of several parts handling urban landscape features: vertex-based geometry modeling, editing and manipulating 3D landscape objects, generating geometrically complex type features with attributes for 3D objects, and texture mapping of complex types using image library. It is a kind of feature-based system, linked with 3D geo-based spatial feature attributes. As for the rendering process, some functions are provided: optimizing of integrated multiple 3D landscape objects, and rendering of texture-mapped 3D landscape objects. By the active-synchronized process among desktop system, OPENGL-based 3D visualization system, and mobile system, it is possible to transfer and disseminate 3D feature models through both systems. In this mobile 3D urban processing system, the main graphical user interface and core components is implemented under EVC 4.0 MFC and tested at PDA running on windows mobile and Pocket Pc. It is expected that the mobile 3D geo-spatial information systems supporting registration, modeling, and rendering functions can be effectively utilized for real time 3D urban planning and 3D mobile mapping on the site.

  • Recently, mobile commerce is widely spread around the world according to fast growth of the mobile communication market. The existing digital document is not well fit in mobile commerce because of weakness of the hardware of mobile devices, low bandwidth of wireless communication, and the constraints of the size and resolution of the display. In this paper, we analyzed the elements of the digital document proper for mobile commerce based on wireless communication, designed the XML form for the digital document, and implemented the X-Auth which is an authoring tool for the XML digital document. X-Auth does not require that the author or user know XML. And also it makes it possible to create the digital document fit for the size of the mobile device display and therefore remove inconvenience due to the scrolls.

  • 국내 휴대 단말기기(Mobile Phone, PDA 및 DMB 폰 등)의 하드웨어적 컨버젼스 기술은 국제 경쟁력을 충분히 확보하고 세계 시장에서 선두 역할을 수행하고 있으나, 휴대 단말기기에 필수적으로 구성되어지는 UI(User Interface)는 상대적으로 낙후된 실정이다. 이에 따라 3차원 그래픽 UI의 구현과 휴대 단말기기의 이벤트에 반응하는 3차원 아바타 시스템 개발을 통해 경쟁력 있는 소프트웨어적 컨버젼스 시대의 대비는 필수적이며, 본 논문에서는 휴대 단말기에서 3차원 UI의 구현 뿐 아니라 쉽고 빠르게 UI를 구축 할 수 있는 Authoring Tool 개발의 시급성을 인식하여 연구를 진행하고 있다.
