TYPES OF VIRTUAL REALITY SYSTEMS

Non-Immersive (Desktop) Systems: Non-immersive systems, as the name suggests, are the least immersive implementation of VR techniques. Using the desktop system, the virtual environment(VE) is viewed through a portal or window by utilising a standard high resolution monitor.

Semi-Immersive Projection Systems: Semi-immersive systems are a relatively new implementation of VR technology and borrow considerably from technologies developed in the flight simulation field. A semi-immersive system will comprise a relatively high performance graphics computing system which can be coupled with either a large screen projector system , multiple television projection systems .

Fully Immersive Head-Mounted Display Systems: All fully immersive systems will give a sense of presence that cannot be equaled by the other approaches discussed earlier, but the sense of immersion depends on several parameters including the field of view of the HMD, the resolution, the update rate, and contrast and illumination of the display.
