  • This study investigates the detrimental effect of watching sexual content in three-dimensional (3D) moving pictures. An increasing amount of investment is put especially in 3D adult content to boost their 3D media industries. It is crucial that the effect of sexual contents on viewers be identified. In this experiment, a between-subject design was employed to analyze various effect of sexual content on participants whether they viewed the same stimuli in 3D or in 2D. In particular, the presence scaling was used to evaluate how real the video clip is. In addition, the permissiveness toward sexual behaviors and the level of sexual arousal were measured to examine the different effect of sexual content by dividing two separate groups in 2D and 3D condition. The result shows that those who watched a 3D video clip perceived higher sense of presence compared to those who watched a 2D video clip. Furthermore, subjects in 3D condition reported lower scores of permissive attitude toward sexual behaviors. This confirms that 3D display delivers more visual experience and has an impact on people in terms of perceiving sexual contents and changing their attitudes towards sexual behaviors.

  • Despite the fact that the mobile environment has favorable conditions for using data contents, it is not easy to implement enhanced data services for mobile broadcasting based on MPEG-4 BIFS. With a structure inherited from VRML, BIFS targets different types of content with a development approach that is not very compatible with broadcasting contents. Furthermore, it is not easy to implement BIFS because the standard is too complicated for the mobile broadcasting environment. Accordingly, this study proposes an enhanced mobile TV contents model that provides interactive 3D objects and GUI for the viewers to interact with the broadcasting contents. By applying the model to the DMB environment, this study suggests a direction for future developments of mobile broadcasting contents. In order to represent 3D graphics on mobile TV, we analyzed MPEG-BIFS 3D nodes and composed a subset of VRML profile, and defined new nodes that can efficiently represent GUI at the content development level. If this study helps facilitate expression of 3D graphics and interactions in data contents composition, enhanced efficiency of contents development is expected to promote the development of various contents suitable for the mobile broadcasting environment.

  • In the smart education era, it is crucial for the teacher to make lecture materials in the form of 3D convergence contents for themselves. In this study, we developed an interactive authoring tool to create 3D convergence contents for the teacher. The proposed system was implemented based on a commercial 3D engine for practicality. To evaluate the usability of the tool, we conducted a satisfaction survey of a focus group. As a result, we concluded that the proposed authoring tool was useful to create desired contents but rather complicated to use due to the text-based script editor. In the following research we will improve the editor so that it can be used in a more intuitive manner.

  • This paper is concerned with the techniques of multitexturing for increasing the image quality of 3D contents in the Internet, where the attributes of objects such as textures are dynamically changed. First we explain the empirical results of implementing the X3D nodes related with the multitexturing in the recent X3D viewers. Next we discuss the directions for developing the next-generation of X3D viewers that satisfy the user requirements and the advanced graphics accelerators.

  • The interest in the service of 3D mobile contents becomes larger due to the technological advance of production and services of mobile contents and the appearance of the exclusive mobile phone for 3D game. Therefore, the researches about the efficient mobile services of large 3D contents are wanted in the circumstances of the narrow bandwidth and the burden of the connection charge of wireless mobile communications. In this paper, we suggest a strategy of caching for looking up and downloading the 3D marine characters efficiently and a system model for mobile service of 3D marine characters. The suggested system is designed for serving efficiently the high-quality 3D characters through the wireless mobile communications using the database on the 3D marine objects of cyber aquarium constructed for the services through the wired internet.

  • History documentaries in Korea have developed various forms of production techniques to overcome the limits of insufficient historical records and videos, and dramatic elements that make the viewers immersed. Through diverse production techniques, history documentaries can maximize the factuality, vividness, and informativeness, allowing the viewers to understand and share the historical events. This paper analyzed the "immersion and experience" techniques of the programs that have been the main turning points of the history documentary so far and produced and realized the virtual reality through utilizing "Uigwe", a 3D history documentary broadcasted on KBS which showed the possibility of applying the virtual reality technique as a new broadcasting contents format.

  • The web technology related with internet at present is changed into the 3D interactive environment form one sided communication of simple contents. In this paper, a high quality interactive Web3D Contents was realized by using the TurnTool, a authoring tool. This paper suggests the method that can easily and quickly realize the Web3D manual which is more realistic md capable of interaction with user. This method makes up for the weak points in the existing Web3D tool system. Therefore we can realize the contents that able to easily interact through minimizing file size md omitting procedure of additional EAI(External Authoring Interface) by using the Java Script.

  • Extensible 3D (X3D) is the ISO standard for defining 3D interactive web- and broadcast-based 3D content integrated with multimedia. With the advent of this integration of interactive 3D graphics into the web, users can easily produce 3D scenes within web contents. Even though there are diverse texture nodes in X3D, projective textures are not provided. We enable X3D to provide SingularProjectiveTexture and MultiProjectiveTexture nodes by materializing independent nodes of projector nodes for a singular projector and multi-projector. Our approach takes the creation of an independent projective texture node instead of Kamburelis's method, which requires inconvenient and duplicated specifications of two nodes, ImageTexture and Texture Coordinate.
