VR (virtual reality) has its roots from the combination of 3D images, computer-assisted instruction, computer gaming, entertainment experiences and equipment simulators. Most VR show immersive environments through mounting them on the head and they supplement or replace the real world and put you into the virtual world. More impressive fact about this VR is that one feels like he/she is in the virtual world like LITERALLY.
Some of this VR surround you in a CAVE (computer assisted virtual environment) through the use of world fixed displays. It’s important to note the application of this VR technology is necessary for the fields like entertainment, educational, and its civic and therapeutic value out ways its demerits which range from physical effects to the potential loss of connection to the reality.
Major merits are:
1. Training and education
VR plays a significant role in the training and teaching sector by providing easy ways to model complex situations that are as a matter of facts life and death problems which trying to solve them in a real world could prove dangerous. Let’s start with an example; a novice student is trying to learn driving, instead of putting the student behind the wheel, the student can use VR, and this can put the student in a safe position without them destroying their properties or others. Other applications of such kinds are
1. commercial aviation
2. military hardware control
3. helping medical students learn surgical without the use of live humans hence gaining immersive experiences without limitation and many more fields that this VR technology is not limited to.
2. Entertainment and Gaming
In partnership with various gaming software, headsets and goggles the VR technology insert gaming participants into this game world that they experience like it’s in real life situations. However such headsets can be costly at times especially those that are designed for the closed faced.
3. Help in Healing
Through simulation of traumatic or disturbing events, such technology can help people like the military soldiers overcome various PTSD (post-traumatic stress disorders) that they made encountered during their operations. The technology basically puts them in the virtual combat situations in modes like gaming, and this makes the members became tolerable to disabling stressors.
Other applications in healing; treating phobias example handling animals or objects.
Physical rehabilitation that is, giving patients the chance to refine ambulatory in a clinic setting before moving to a real life situation.
4. Planning and Architecture
Here applying the virtual reality technology to the field of planning and architecture gives a clear picture in virtual forms of how the outcome would be.It makes work easier since now websites can serve up fly-and this is by reconstruction of the real cities, the only thing left is to incorporate onscreen viewing into the VR headset
Demerits of VR are:
1. Despite the practical applications that VR provides to real life situation, it’s important to remember real life requires actual full mastery rather than the modeled. Hence poor mastery in the VR training can result to poor real life performance.
2. Continuous use of the VR leads to desensitization of one’s correspondence with real life situation. That is, the inability to perceive and react to the real world. This occurs mainly due to the preference of virtual reality over the reality.
3. The VR that becomes so real or too simulating can cause setbacks to any form of treatment.
