The workings of virtual reality

Virtual reality is a way to create a computer-generated environment that immerses users into the virtual world. When we use a VR headset, we need a simulation set-up that makes us feel far away from the real environment.

While from the perspective of the experience we understand the concept, how the technical part that allow everything to happen. Do you really know how virtual reality works?

The main aim is a virtual reality simulation of vision. Each headset’s goal is to enhance the experience by creating 3D environments in depth. Each VR headset has attached screens (one for each eye), eliminating all interaction with the real world. Autofocus lenses are typically positioned between the screen and the user’s eyes to adjust according to the movement and position of the individual eye. Visuals on the screen can be displayed either by using a mobile phone or an HDMI cable connected to a PC.

Many businesses benefit from this new technology, especially those involved in construction and design. For more information BIM Technology, visit a site like

For virtual reality to create a truly immersive world there are certain prerequisites – a minimum frame rate of 60fps, the same refresh rate and a minimum of 100-degrees in the field of view, although the absolute ideal would be to have a 180 degree field of view.

Apart from the images, there are several other elements that aim to create a deep VR experience, making users truly engrossed in a virtual environment and these include sound quality and eye and head tracking abilities.
