Interactive intervention of the human presenter is one of the important factors that make the visualization more effective. Rather than just showing the content, the presenter enhances the process of the information delivery by providing the context of visualization. In this paper, we define this as an augmented presentation. In augmented presentation concept, the presenter can facilitate presentation more actively by being fully immersed in the visualization space and reaching and interacting into digital information. In order to concrete the concept, we design presentation space that enables the presenter to be seamlessly immersed in the visualization. Also we increase the presenter's roles as a storyteller, controller and augmenter allowing the presenter to fully support communicative process between the audience and the visualization. Then, we present an augmented presentation system to verify the proposed concept. We rendered 3D visualization through a half-mirror film and a wall projection screen that are place in parallel and applied with stereoscopic images, then, spatially align the presenter inside the virtual visualization space. After that, we conduct a controlled experiment to investigate the subjective level of immersion and engagement of the audience to HoloStation compared to traditional presentation system. Our initial investigation suggests that the newly conceived augmented presentation has potential not only to enhance the information presentation but also to supports the delivery of visualization.

We propose an algorithm which detects the touch of the fingertip on a general wall using the shadow information. Nowadays, there is a demand for presentation systems which can perceive the presenter's action so that the presenter can use natural movements without extra interface hardware. One of the most fundamental techniques in this area is the detection of the fingertip and the recognition of the touch of the fingertip on the screen. The proposed algorithm recognizes the touch of the fingertip without using the depth information, and therefore needs no depth or touch sensing devices. The proposed method computes the convex hull points of both the fingertip and the shadow of the fingertip, and then computes the distance between those points to decide whether a touch event has occured. Using the proposed method, it is possible to develop a new projector device which can perceive a fingertip touch on a general wall.

In this study, we propose a 3D virtual reality based presentation training system to help implement the virtual presentation environment, such as the real world, to present it confidently in the real world. The proposed system provided a realistic and highly engaging presentation and interview environment by analyzing the speakers' voice and behavior in real time to be reflected in the audience of the virtual space. Using HMD and VR Controller that become 6DOF Tracking, the presenter can change the timing and interaction of the virtual space using Kinect, and the virtual space can be changed to various settings set by the user. The presenter will look at presentation files and scripts displayed in separate views within the virtual space to understand the content and master the presentation.

본 논문은 지능형 TV에서 QoS 개선을 위한 MPEG-4 미디어 프리젠터 개발이다. 사용자들이 단순히 수동적인 미디어 사용을 벗어나, 능동적으로 참여 가능한 상태로 변환하며, 다양한 하이퍼미디어를 제공함으로써 정보 서비스의 질적 향상을 지원한다. 화면에 나타난 장면에서 사용자 이벤트를 실시간으로 처리하고, 독립적인 바이너리 세마포 구조인 변형된 원형버퍼를 사용하여 네트워크를 통해 전달된 미디어 스트림을 버퍼링하여 효율적인 상호작용을 지원한다.

An algorithm is presenter for generating the most probable states in decreasing order of probability of each unit. The proposed new algorithm in this note is compared with the existing methods regarding memory requirement and execution time. Our method is simpler and, judging from the computing experiment, it requires less memory size than the previously known methods and takes comparable execution time to previous methods for an acceptable level of criterion.

본 논문에서는 MPEG-4에서 정의된 멀티미디어 객체를 효율적으로 랜더링 하고 사용자 이벤트 모듈을 처리하는 프리젠터를 제안한다. 제안한 프리젠터는 시스템 디코더를 통해 생성된 결과인 드로우 노드 리스트와 라우팅 노드 리스트를 탐색하여 화면상에 각 객체를 랜더링 하고 사용자 이벤트를 처리해 준다. 프리젠터는 이 노드 리스트를 탐색하여 각 객체를 랜더링 함으로써 재생에 필요한 노드 탐색 시간을 줄일 수 있고, 사용자 인터렉션에 대한 장면 변경도 신속하게 처리하여 재구성할 수 있다.

In previous studies, high fever, inappentence, increased respiratory rate, muscle tremors, anemia, jaundice, loss of weight hemoglobinenuria and hemoglobinuria were found in dogs infected intraerythrocytic protzoan parasites of the gennus Babesia. These changes were mainly caused by the intravascular hemolysis. In this study, a Pit Bull Terrier, which was infected by babesia, was investigated clinical signs and patterms of blood. The findings from this study indicated that dog with severs clinical signs shown erythropenia, lymphocytophilia, neutropenia, thrombocytopenia and eosinpenia. Furthermore, it presenter low level of hemglobin and hematocrit. However MCV, MCH and MCHC did not decreased as compare to normal dogs.

본 논문은 실시간 운영체제 환경에서 사용자 상호작용을 지원하는 MPEG-4 미디어 프리젠터를 제안한다. 이를 위해서 제안하는 미디어 프리젠터는 객체에 발생한 이벤트 정보를 객체속성 정보와 함께 파싱하여 이벤트에 반응하는 기능을 가진다. 따라서 사용자는 멀티미디어가 재생되는 동안 이벤트를 발생하고 프리젠터가 이에 반응하는 장면을 실시간으로 관찰함으로써 능동적 상호 작용을 이룰 수 있다. 재구성된 화면의 재생은 MPEG-4의 중요한 특징인 사용자와 미디어 프리젠터 간의 상호 작용을 보인다.

It is advantageous to use XML in developing user interfaces, since XML is independent from platforms and languages and it is easy to learn and use. The existing XML-based languages do not adopt formal model, and they are developed in ad hoc manner. Moreover, they provide limited facilities to handle user events, and combine user interface components with internal logics. In this paper, we introduce an extended MVP (EMVP) model, which is extended from MVP (Model-View-Presenter), and XUIML, which is a new XML application based on the EMVP to support user interface. XUIML provides useful methods to build user interface, including methods to describe actions on user events, data flows between objects, and internal logics. The XUIML system provides two style editors - text editor and graphic editor. It also provides two code generators. One generates Java source, and the other generate C# code from XUIML document. The XUIML graphic editor allows users to manipulate XML elements directly, and we can gain high productivity with the graphic editor.
