CHAPTER II: LITERATURE REVIEW

Introduction

This chapter defines a Virtual Reality (VR) technological characteristics and their relevance for VR and implications for learning. Evidence suggesting VR has the potential to be a new type of learning environment. Moreover, a number of possible tools and technologies for building VRLE will be introduced. So this chapter presents basic concepts of Virtual Reality and discusses its potential application in teaching via the Internet by creating learning systems in the form of three-dimensional, interactive virtual worlds. It welcomes the specification language standard VRML (Virtual Reality Modeling Language) as a means to create online virtual worlds that are accessible to students using browsers or browsers that incorporate VRML viewers.

The emergence of Internet as a communication medium has meant that access to information simple and fast. Most of this information resides in the popular Web pages, which often have text and images in two dimensions. The real world is three dimensional, so that by reducing the "world" Web two-dimensional information is missing, hence the desirability of integrating third dimension, allowing for example, tour the facilities of a museum or a university to get the information that will interest the visitor. This is a reality that can be achieved through a Modeling Language virtual reality as VRML (Virtual Reality Modeling Language).

An important field of computer science called "Virtual Reality" has important applications in education, to stimulate the learning process. Virtual reality applications get an effect called "immersion", which states that "students can fully interact with the artificial environment using the senses of touch, hearing, and the view through special devices that are connected to the computer, such as" data gloves "and small video monitors inside a helmet. These devices have sensors that detect movement accurately, affecting the virtual world in which students are immersed" (Garcia Ruiz, 1998). This technique can be moved to the Internet using VRML, the language with which you can create a cyberspace with virtual worlds, users can store and share information virtual worlds in this environment, where they act as active participants. Students can learn practically any area of ??knowledge using this technology.( Kirriemuir, 2011)

Related Review

Virtual Reality (VR) can be described as a multi-sensory, highly interactive computer environment that makes the user believe that he/she is actually experiencing a situation even though they are, in reality, participating in an artificial environment (Gigante, 1993; Kameas et al., 2000; Roussou, 2004). VR is defined as a Three-Dimensional (3D) graphical simulation model where a user can control the viewpoints and motion and interact intuitively in real time, making the virtual experience feel actual or real (Wilson, 1999; Moshell and Hughes, 2002). VR allows the user to experience situations that might be too dangerous in real life such as fire-fighters (Ericson and Smith, 2008). Through VR technology, users may explore the real world in a virtual setting, experiencing a given situation at a different scale ...
