Abstract There’s no need to introduce the first speaker of this morning as he is, arguably, one most renowned semioticians in world. During his brilliant career has published extensively on topic virtual realities and will present us latest research defining technology our times: Simulatron. Specifically, focus 2053 incident which took place inside world SimuLife during all users lost ability u...

Along with the success of the massively multiplayer role-playing gaming industry in Asia, online gaming-related crimes have grown at an amazing rate. Most of the criminal cases are related to virtual properties since markets have developed for the virtual properties giving them real world values. There has been little research and resulting technologies for MMRPG virtual property protection. In...

Recently Java programming environment has become so popular. Java programming language is a language that is designed to be portable enough to be executed in wide range of computers ranging from cell phones to supercomputers. Computer programs written in Java are compiled into Java Byte code instructions that are suitable for execution by a Java Virtual Machine implementation. Java virtual Mach...

JavaInJava is a Java virtual machine written in the JavaTM programming language. The system was built at Sun Microsystems Laboratories in order to examine the feasibility of constructing high-quality virtual machines using the Java programming language and to experiment with new virtual machine implementation techniques. In this paper we describe the overall architecture of JavaInJava and summa...

NPCEditor is a system for building a natural language processing component for virtual humans capable of engaging a user in spoken dialog on a limited domain. It uses a statistical language classification technology for mapping from user’s text input to system responses. NPCEditor provides a user-friendly editor for creating effective virtual humans quickly. It has been deployed as a part of va...

Parrot is a virtual machine designed to be a target for languages that have traditionally been run using an interpreter. The virtual machine and its assembly language include many high-level features such as objects, thread synchronization support, and garbage collection. It is set apart from other virtual machines by its register-machine structure, while many other contemporary VMs use a stack...

KEYWORDS Virtual Reality Modeling Language (VRML), distributed virtual environments, multiuser environments. ABSTRACT VRML —the Virtual Reality Modeling Language— has already become the standard for the distribution of 3D virtual worlds on the Internet. Recently several enhancements have been made to extend it by behaviors, most of them altering the current standard radically. In this paper we ...

In such an environment a query language will serve for more than "a souped-up version of X-Pointer". Our position focuses on the use of an XML query language as a view definition language that drives XML mediator systems. A mediator selects, restructures and merges information from multiple autonomous sources/sites. It exports an integrated XML view document. Possible applications of such media...

On the Web and on informatics systems, 3D virtual worlds used become big both in number and in size. Therefore, we propose in this paper a new method for retrieving 3D virtual worlds based on the semantics and the content. Firstly, we propose a new classified database of 3D virtual worlds given in VRML format. To achieve the semantic method, we construct an ontology that describes virtual world...
