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.

The purpose of this study was to investigate the effects of power blog self-presentation and on-line shopping mall reviews on the word of mouth (WOM) effect and apparel purchasing behavior. Consumers living in Seoul and Gyeonggi received questionnaires. There were 303 usable forms that could be analyzed by descriptive statistics, factor analysis, Cronbach's alpha, and regression analysis. The results were as follows: There was a significant effect of power blog self-presentation such as interactivity, media effect, and business intention on information acceptance through WOM. Power blog self-presentation, such as interactivity and business intention, affect information delivery by WOM significantly. There was a significant effect of review consideration, such as agreement, usefulness, enjoyment, and purity, on information acceptance of WOM. Reviews describing enjoyment, purity, and usefulness affect information delivery of WOM significantly. Business intention, media effect, and purity directly affect apparel-purchasing behavior, and affect the WOM effect as a mediator variable and then purchasing behavior. Whereas, interactivity, overstatement, and enjoyment affect the WOM effect as a mediator variable, and then affect overall purchasing behavior. Therefore, fashion firms consider active interaction with power blog visitors and promote the way of enjoying with fun through review of apparel on-line shopping mall when they try to implement viral marketing with WOM effect.

In the distributed multimedia document system, media objects distributed over a computer network are retrieved from their sources and presented to users according to specified temporal relations. For effective presentation, synchronization has to be supported. Furthermore, since the presentation in the distributed environment is influenced by the network bandwidth and delay, they should be considered for synchronization. This paper proposes a distributed multimedia presentation system that performs presentation effectively in the distributed environment. And it also suggests a method to supports synchronization, in which, network situation and resources are monitored when media objects are transferred from servers to a client. Then a feedback message for the change of them is sent to the server so that the server might adjust the data sending rate to control synchronization. To monitor the situation of network, we use two methods together. One is to manage the level of the buffer by setting thresholds on a buffer and the other is to check the difference between the sending time of a packet from the server and the arrival time of the packet to the client.

This paper described the effect of subjective approach in case of the human sensibility experiments. The procedure is proceeded subjectively. Human faces are selected as the image presentation media. Pleasant and unpleasant images are selected directly by examiner, And also the image presentation system, which is executed with a computer and has the square-type black box monitor equipment, is manufactured. Images are presented with the step-variation time interval technique. questionnaire test and EEG signal detection data are analyzed. The analysis parameters are a “frequency band integral value” and a “band differential variation ratio”. he results show the high sensibility and fast response. The fact that image presenting repetition alleviates is verified.

In this paper, we describe a design method to manage heterogeneous objects for effective presentation of multimedia application. In order to utilize the individual feature of a heterogeneous object, we define a specialized class for each media object, and it also gives a method to process each specialized class combined with various figures that can support user-definition during the authoring phase for a multimedia presentation. The proposed data structures and processing methods are designed to easily extend the functions for handling a data objects by adding another specialized class definitions to existing object classes.

Recently, various equipments have been developed for convenience of presentations. Presentation equipments added the keyboard and mouse functions to laser pointer and devices have become main method. However these devices have demerits of limited action and a few events. In this paper, we propose a method which increases the degrees of freedom of presentation as the control of the hand by using a depth camera. The proposed method recognizes the horizontal and vertical positions of hand pointer and the distance between hand and camera from both depth and RGB cameras, then performs a presentation event as the location and pattern that the hand touches a screen. The simulation results show that a camera is fixed on left side of the screen, and nine presentation events is correctly performed.

As oral trial principle and civil participation in criminal trials spread, the environment of Korean courtroom is in need of a systematic introduction of trial presentation which can supplement with the oral trial presentation's weakness. Therefore this study analyzes the definition, types, and effectiveness of trial presentation, considering characters of the Korean court's environment. As for following research step, the most widely used trial presentation softwares in the USA and Korea are analyzed and compared in consideration of the particularity of the trial presentation. Based on this analysis, this study suggested elements to be included in the presentation software optimized for Korean court's environment as follows: 1. Ease of the insertion of various forms and media, 2. Appropriate limitation of the spectrum for graphic style, 3. Ease of use of graphics tools, 4. System functions. Such a suggestion was proposed not only to enhance the clarity, accuracy, effectiveness in developing insistence and delivery of content, but also promote aesthetic quality and consistency of presentation's visual communication aspect.

The decision to actively reveal oneself as a consumer on social media depends on whether the focus is more on positive rewards than negative threats associated with self-presentation, that is, who the other party is in that relationship. The audience of self-presentation could also be divided into expressive and instrumental ties: work partners can be classified as an audience of instrumental ties, whereas school friends can be regarded as an audience of expressive ties. This study accordingly predicted that people would focus more on prevention of negative threats than positive reward, exhibiting defensive self-presentation in relationships with strong instrumental ties because the fallout from negative threats due to failed self-presentation have a more detrimental effect than a positive reward from successful self-presentation. The empirical findings thereby indicated that as the proportion of coworkers increased among Facebook friends, the mediation effect through defensive self-presentation increased, whereas such effect through acquisitive self-presentation decreased.

Instagram, a photo and image centered social networking service, has received increasing attention these days, from scholars and practitioners. However, little is known about the social and psychological factors that lead consumers to use this service. To provide a baseline understanding on Instagram users, the current study was conducted to discover perfectionistic self-presentation tendency expressed by the Instagram users and explore the relationships between identified perfectionistic self-presentation and intention to use Instagram variables with 250 participants. In addition, this study tried to determine the moderator effect of self-efficacy and self-construal. A comprehensive survey was directed and a total of 380 participants were recruited to verify anticipated hypotheses and research questions. The research results suggest that perfectionistic self-presentation has five sub factors: others conscious self-presentation, subjective self-presentation, environmental adaptation self-presentation, self-expansion self-presentation, and social self-presentation. The implications of this research findings are discussed.
