In this article I shall discuss the most basic VR terms to ensure everyone is up to scratch with the fundamentals on all things Virtual Reality – it is a good starter point for enthusiasts or those working in technology that want to break in to this market…
When you work in a niche industry it is easy to forget that not everyone will understand concepts and terms related to your industry.
See this article as a glossary, or at least a reference that you can use whenever you want to look something up that is VR related.
VR - Virtual Reality
Virtual Reality and VR was coined as a concept in the late 50s and 60s. It is a visualization technique that creates an artificial environment, and simulates the user's physical presence and user interaction with others. Virtual reality can also create artificial sensory experiences that can include vision ,touch , hearing and smell .
AR - Augmented Reality
Augmented Reality is a visual technique that uses live video which is then amplified or augmenteras of computer-generated graphics. A simple example of this could be a video where you see the nameplates over the heads of everyone attending. Or that you see an artificial list that appears on the fridge on what needs to be purchased. There are also promising applications in distance learning, and help more professionals who need visual aid in their work.
MR - Mixed Reality
Mixed Reality sometimes called hybrid reality, is a combination of real and artificial worlds to produce completely new environments and visualizations where physical and digital objects coexist and interact. The name MR is the newest of the three and consists of a mix of VR and AR.
The name of the VR equipment you have on your head. Can also be called VR goggles or HMD (Head Mounted Display) contains either fixed screens, or has space to tuck a cell phone. Contains (Oculus Rift, HTC Vive, OSVR, PSVR) even technology to detect how you tilt your head. May include headphones (Oculus Rift).

Technical VR terms
Technology to track what your eyes are watching, through your pupil filmed by small cameras.
Technology to change the resolution of the image dynamically. Used with Eyetracking and results in that only good quality (demanding for computer / mobile) where you look.
Bring to track where in the room your headset is used various external technicians with cameras and laser systems. With the "inside-out tracking" is used instead of a camera on the headset which makes the whole system simpler and has fewer parts.
Using the look in a VR experience to make choices. Watching a button click by holding gaze for a while.
FOV - Field of View.
The size of the field of vision that you see in your VR headset. A man looks about 240-270 degrees, with varying quality. Today's VR headset gives between 90 and 150 degrees.
Latency means delay or lag and is one of the most important parameters for good WR.The limit for bail latency is 20ms
Exercise to photon latency
Delay it takes from the moment you turn your head in VR, until a new updated and accurate picture appears in your eyes. Must be under 20ms for it to feel good.
The important part when it comes to things you have on your head. Weighed in the 90s several kilos, but now stands at 300-600 grams. The lower, the better. The ultimate goal is a VR headset that looks like a pair of glasses and weighs less than 100 grams
Video filmed with a special 360-camera that takes up everything that happens around it.Do not need to be operated by a cameraman, but brings new challenges for directors so the image can not be controlled in what the viewer sees. in the current situation mono and lacking depth perception. Can filmed and edited normally and also be live.
See above. 3D version of the 360. filmed with two cameras and two lenses. Provides 3D image depth. Can filmed and edited normally and also be live.
Technology that tricks the user into thinking that it goes in a straight line, when in fact goes in a circle. Allows one to simulate the long-distance transport in small spaces. In the current situation needed a circle of about 40 meters in diameter that you will not feel the difference.
GVS - galvanic vestibular stimulation
Is a technology for the electrical stimulation, a nerve in the ear to affect the balance. VR can for example make it possible to simulate the sensation of acceleration and moving up and down...
