Virtual Reality terms you should know
It is a kind of highly controlled physical system which assists in simulation of display motion into the real motion senses in VR world. It provides life to all captured digital elements and let users believe that they are playing with a world of all living things.
Eye Tracking works same as that of head tracking and assists to keep users eye in motion as per requirement of VR stuff. HMD assists in proper tracking of eye and head with integration to VR content,if talk about VR games then this feature makes you feel the reality inside gaming world and when you have to aim on targets then they can be controlled like real world movements.
Here we are going to talk about the sensors that track movement of users head and keeps images moving in such a manner that they match head positions perfectly. For example if you are using a Oculus Rift then the head tracking feature will force your head to look up, down, right and left so that you can see world in the way virtual reality wish to make you see.
It is described in terms of the ability to record all movements in such a manner that they appear to be a part of real world. It will help you to get a closer look of every element that you want to observe in VR content, same as that of real life. It is one of the biggest elements in the world of Virtual Reality that forces your senses to get involved with the tricky science of virtual environment without feeling that you are wondering in a fantasy world.
When you are looking at a series of images in the world of Virtual reality then refresh rate helps to control the movement of frames so that they can be managed to move at faster or slower rate as per requirement. Refresh rate controls lead and lag of series of images in such a manner that users avail a responsive experience. At standard rate, users need 60 frames per second.
Head Mounted Display (HMD)
This term will be more often used when you enter to the world of Virtual Reality because it is associated with reading and hearing abilities in VR technology. In simple terms, HMDs are the specialized form of hardware that is responsible to deliver VR experience to users. It is designed in shape of a helmet or goggle that users can strap on their face easily or can wear on their head. The usage depends upon need of you VR gear because some sensors work with head tracking whereas others do not need such elements.
If you have ever experienced the world of Virtual Reality then you surely might have noticed that whenever you move your head in the directive motion then the visuals do not keep up accordingly, this is called as latency. This is an unpleasant thing about Virtual Reality that adds a limitation to match virtual world with real world. The lag caused by this latency period is a complaint from VR content users and it occurs due to a variety of reasons.
The combination of VR and MR leads to immersive experience of users where high end manipulations can be done on images, sounds as well as other stimuli so that they can stay alive in artificial environment.
Field of View (FOV)
The term Field of View presents the angle of visual field in degrees where it is important to keep FoV higher to that immersion can be extended to higher end of scale. Technically, the viewing angle of human eye reaches up to 200 degrees thus it becomes important to raise angle of FoV so that higher immersion can be resulted.
Screen resolution actually describes the number of pixels to be displayed on screen during Virtual Reality scenes. Same as the concept of television monitor or computer screen, more number of pixels means much better resolution and much clearer as well as realistic quality of images. The technology of Virtual Reality serves with awesome resolution and cameras developed for capturing such images are designed to add more number of pixels per frame. With specially developed VR headsets, the screen is divided into two portions that are observed by each eye separately and the screen door effects added to VR technology makes users feel like they are watching through a door.
First of all it is important to know the actual meaning of VR that stands for Virtual Reality. The VR immersion is actually achieved by mixing two most important senses of living beings that are vision as well as hearing; for this VR technology utilizes headphones and headsets. With VR environment you will feel real life in photographs also and the experience with memories will go amazing.
It is simply the process of overlying of digital elements or data on the real world so that you can interact with reality and digital elements on same platform. Although, Augmented Reality technology is still running behind Virtual Reality but the day they will converge then real wonders will be created with mixed reality effects.
The convergence of Virtual and Augmented reality is known as mixed reality. MR creates blend of virtual world into the physical space and it has power to bring life into digital elements resulted by highly advanced camera units and VR+AR gears.
