Brief Guide: Virtual Reality Explained

Virtual reality is an amazing technology that can get a subject to escape the real world and get immersed in a computer-generated world. Experienced developers engaged in mobile app development UAE are finding ways to integrate this technology into their apps. But you may wonder how is it able to seem so real and get you as engaged as it is.

We shall consider how this technology operates so that you can have a better understanding of the next time you place the headsets on. It may also be able to inspire your next mobile app development UAE project.

Vision Simulation

The technology hinges on the ability to simulate the way the eye perceives reality. It is about creating a 3D image with dedicated screens for each eye and cutting out the perception of the real world so that whether you look right or left, what you see is what is on the screen. A mobile phone can then be used to render the images onto the screen.
The screen then has to be able to feed the eyes with pictures at a rate that is fast enough to make it believable. This means it should have a frame rate not less than 60 frames per second with the ability to move around freely at the same angle with the eye movement.

Timing is of the essence here as a lapse in the frame rate can make the eyes aware of the time gap and that would change the entire visual experience.

Images need to be flashed and refreshed fast enough for the eyes to find the action believable. It is all about tricking the eyes with speed.

Head and Eye Movement

Another element is the movement of the head and the eyes. Virtual reality uses laser pointers to track the movement of individual’s heads and eyes so that the image they see will correspond with their movement and thus create that 3D effect which is like the real world where every movement of the eye is met by an object.


Sound plays a big part in the way we perceive things in the real world but more so in the virtual world. The sound needs to be synchronized with the images that are flashed onto the screen to create the best reality as the person views the images. There needs to be coordination between the sound effects and the images on the screen. This is even the same when it comes to ordinary 2D videos.

Opportunity for Advancement

What we experience today is not the end of it. Several companies are working to create an even more exciting experience for VR enthusiasts. There is more that can be done to make the reality even more real with other elements like the ability to include smells and touch as part of the experience. In the coming years, we can expect to see more impressive VR graphics, better sound quality and much more, some of it we may not yet have imagined it but it will be a reality.
