Lets us first understand what Virtual is and what Reality is. The word virtual means near and Reality means what we experience as human beings. Therefore, it is clear that Virtual reality means Near-Reality. Alternatively, we can say it refers to a specific type of reality emulation.
In technical terms, the virtual reality is the term, which is used to describe the three-dimensional computer-generated environment, which can be interacted and explored by the person, and the person becomes the part of this virtual world within the environment and can manipulate the objects to perform the series of actions.
Virtual reality is a synthetic surrounding, which is created with the software and presented to the user in such the simplest way that the user suspends belief and accepts it as a true surrounding. On a PC and laptops, the virtual reality is primarily experienced through two to five sense such as sight and sound.
The simplest style of VR technology could be a three-D image that may be explored interactively at a private pc, typically by manipulating keys or the mouse so the content of the image moves in some direction or zooms in or out.
Virtual reality is divided into two parts:
The simulation of a true surrounding for coaching and education.
The development of associate unreal surroundings for a game or interactive story.
Features of Virtual Reality Systems:
There are many types of virtual reality systems available, but all these systems share the same characteristics as the ability to allow the person to view the 3- dimensional images. These all images appear life-sized to the user. It can change as the person moves around their environment, which corresponds within the changes in their field of vision. The objective is for a seamless join between the eye movements and person’s head to the appropriate response for example change in perception. This ensures that the virtual reality environment can be both realistic and enjoyable.
The virtual environment provides the appropriate responses in real-time as the person explores their surroundings. The main problem comes when there is a delay between the user’s actions and in system response, which disrupts their experience.
The technology of virtual reality:
Virtual reality becomes the most recognizable component in the head-mounted display. In the present time, human begins virtual creatures and then display technology. The biggest difference between immersive virtual reality systems is traditional user interfaces. VR is using in computer technology, which is used to create simulate the environment. The technology of VR helps in viewing a screen in the front of users and able to interact with 3D worlds.
Elements of VR Technology:
Impact of sound:
Sounds effects when it synchronizes with the visuals and creates very engaging effects. With the using of headphones 3D sound effects the person’s belief in a virtual environment.
Head and Eye Tracking:
The user’s head and eye tracking can be ensured using laser pointers such as mobile sensors and led lights. In a mobile sensor, there is accelerometer, which is used to detect the three-dimensional movement for angular movement and magnetometer to identify the position on the earth. If you need high accuracy of sounds, then sensors and cameras can be installed in the room where you can use the headset.
