Contemporary business organizations are increasingly turning their attention to jointly creating value with a variety of stakeholders, such as individual customers and other business organizations. However, a review of the literature reveals that very few studies have systematically examined value co-creation within online group buying. This study reveals that there are different mechanisms und...

The objectives of this work are a recreation of 3D models of selected archaeological open-air and roofed theatres of the Hellenistic and Roman period, and a creation of the real-time crowd engine in order to animate autonomously the virtual audience. We present a methodology for creation of virtual audience using a collection of tools, including custom ones developed specifically for this task ...

While virtual reality is a powerful tool for a range of applications, it has the following two associated overheads that fundamentally limit its usefulness: (1) The creation of realistic synthetic virtual environment models is difficult and labour intensive; (2) The computing resources needed to render realistic complex environments in real time are substantial. In this paper, we describe an ap...

Digital broadcasting enables interactive TV, which presents new challenges for interactive content creation. Besides the technology for streaming and viewing, tools and systems are under development that extend traditional TV studios with virtual set environments. This presentation reviews current technology and describes the requirements for such systems. Interoperability over the production, ...

The educational collaborative virtual environment supposes the active participation of students and teachers, interacting highly and aiming the knowledge exchange and creation of new abilities. The learning becomes a process that one assists the other to reach the objective, by changing experiences, dialogues, discussion of ideas, accomplishment of group, and individual activities that can be s...

This text proposes to examine the virtual lives and creative activities of two metaverse avatars, Eupalinos Ugajin and Naxos Loon, by examining the correlations between their acts of creation and the notion of ‘play’. These will be examined against the backgrounds of Arthur Koestler’s book “The Act of Creation” and Johan Huizinga’s “Home Ludens”; involving a scrutiny on how these may apply to a...

One of the most successful and useful implementations of 3D virtual worlds is in the area of education and training. This paper discusses the use of virtual worlds in education and describes an innovative 3D visualization design project using one of the most popular virtual worlds, Second Life. This ongoing project is a partnership between IBM and three universities in the United States: the Un...
