Development of 3D interactive network applications requires standards for representing 3D content as well as metadata standards for describing the content. In this chapter, selected standards for content representation and content description are presented. In particular, the VRML, X3D, and MPEG-4 ISO/IEC standards are presented. Other standards such as U3D, COLLADA, and 3D XML are also discuss...

In this paper a collection of prototype applications developed by VRT –as part of the ICoSOLE project– are described: Moments, Trademark and the Wall. Together, they form the The Wall of Moments. The aim is to collect valuable usergenerated content, in order to create a near-to live immersive experience for event visitors as well as people who can’t attend an event. Author

We propose a novel, interactive content-aware zooming operator that allows effective and efficient visualization of high resolution images on small screens, which may have different aspect ratios compared to the input images. Our approach applies an image retargeting method in order to fit an entire image into the limited screen space. This can provide global, but approximate views for lower zo...

In the paper we discus about design of universal environment for solution of creating effective multimedia applications with accent on the implementation of interactive elements with the possibility of using the adaptive systems (AS). We also discuss about possibilities of offline presentation of this interactive multimedia adaptive animations using Adobe Flash. We propose a scheme of implement...

OBJECTIVE To develop a computer based learning (CBL) program in diabetes management for health care providers and academic staff MATERIAL AND METHOD A CBL program was developed using "Authorware Professional ver. 6. 0" software. Content validation, computer background survey and investigation of the usability of the program, was conducted as part of the production of this program. The involve...

This paper focuses on incorporating individual differences in cognitive processing and semantic mark-ups in the context of adaptive interactive systems. In particular, a semantic Web-based adaptation framework is proposed that enables Web content providers to enrich content and functionality of Web environments with semantic markups. The Web content is created using a Web authoring tool and is ...

We study departures from network neutrality through implementing a Quality of Service tiering regime in which an ISP charges for prioritization on a non-discriminatory basis. We find that Quality of Service tiering may be more efficient in the short run, because it better allocates the existing network capacity, and in the long run, because it provides higher investment incentives due to the in...

T-learning —the provision of educational services over Interactive Digital TV— is regarded as a complement to e-learning solutions, whose scope is limited due to the digital divide. The increasing connectivity, together with the fact that IDTV users are no longer passive spectators, permits to start thinking on highly interactive services that support fluid communication among users and service...

Recently, thanks to the increasing availability of enabling technologies for multimedia and interactive content broadcasting, providers are trying to provide more and more comfortable and user-transparent communication services to end-users. Some of the main problems, inherent in this kind of system-design, are user localization and user identification. In the present work, problems have been f...

No other area of the upcoming Information Superhighway promises providers of technology and content as many business opportunities as Interactive Television (ITV). In Germany, one of the technologically most advanced countries in Europe with a high quality telecommunication network, six pilot projects are underway. Each has a different approach and varying participants, although all pilots are ...
