An Augmented Reality system supplements the real world with virtual (computer-generated) objects that appear to coexist in the same space as the real world. While many researchers broaden the definition of AR beyond this vision, we can generally find Augmented Reality system to have the following properties: 1) Combines real and virtual objects in a real environment; 2) Runs interactively, and in real time; 3) Aligns real and virtual objects with each other.
Augment Reality can be thought of as a ?middle ground? between Virtual Environment (co ....etc

Augmented Reality
Introduction
Augmented Reality (AR) is a growing area in virtual reality research. The world environment around us provides a wealth of information that is difficult to duplicate in a computer. This is evidenced by the worlds used in virtual environments. Either these worlds are very simplistic such as the environments created for immersive entertainment and games, or the system that can create a more realistic environment has a million dollar price tag such as flight simulators. A ....etc

A mobile virtual reality service (VRS) will make the presence and presentation of the sounds and sights of an actual physical environment virtually available everywhere in real time through the use of mobile telecommunication devices and networks. Furthermore, the VRS is the conversion of a physical system into its digital representation in a three-dimension (3D) multimedia format. This paper addresses one aspect of the notion of bringing an actual multimedia environment to its virtual presence everywhere in real time .

Quantum cryptography becomes a reality
According to reliable sources from NEC, Commercial quantum cryptography, a revolutionary system that can produce quantum keys at a speed of 100Kbit/s and then broadcast it up to 40 kilometres along the commercial fibre optic lines will be available in the markets by the second half of 2005. Speaking in line with Kazuo Nakamura, senior manager of NEC's quantum information technology group at the company's Fundamental and Environmental Research Laboratories, it ca ....etc

Definition
Augmented reality (AR) refers to computer displays that add virtual information to a user's sensory perceptions. Most AR research focuses on see-through devices, usually worn on the head that overlay graphics and text on the user's view of his or her surroundings. In general it superimposes graphics over a real world environment in real time.
Getting the right information at the right time and the right place is key in all these applications. Personal digital assistants such as the Palm and the Pocket PC can provide timely informat ....etc

Mobile Virtual Reality Service (VRS)


A mobile virtual reality service (VRS) will make the presence and presentation of the sounds and sights of an actual physical environment virtually available everywhere in real time through the use of mobile telecommunication devices and networks. Furthermore, the VRS is the conversion of a physical system into its digital representation in a three-dimension (3D) multimedia format.

VRML is a language for creating 3D models using a set of primitive geometrical shapes. Some browsers such as Netscape have plug-ins ( Live 3Dand Cosmo Player) at enable you to view these 3D structures. The most well known open browsers are Openvrm, Freewrl,Vrmlview The most powerful aspect of VRML is that it provides sy access to manipulation and visualization of 3D objects for 'ordinary people'. In the past, 3D graphics of this quality was only accessible to those with powerful (and very expensive) workstations. An even more important aspect o ....etc

Virtual Reality (VR),
system that enables one or more users to move and react in a computer-simulated environment. Various types of devices allow users to sense and manipulate virtual objects much as they would real objects.

This natural style of interaction gives participants the feeling of being immersed in the simulated world.

Virtual worlds are created by mathematical models and computer programs. ....etc
