When we talk about Virtual Reality (VR) technology we are referring to computer systems capable of generating an interactive three-dimensional (3D) interactive environment, immersive and multisensorial. As a result of its interactive nature, a VR application will be able to react immediately (in real time) to the user's activity in front of a situation or event that is presented. This reaction, user-perceived, causes an illusion of real presence within the simulated environment. In the paper VIRTUAL REALITY TECHNOLOGY we analyze some of the fundamental technological aspects required to achieve this.
