When generally talking virtual realities it refers to a computer technology that involves creating a special unique world which mostly is in three-dimensional. The user of the world can explore and manipulate it while having a feeling as if he was in that world. This technology was invented by a combination of engineers, theorists and scientists and the most important thing with this is that they have also invented relevant applications and devices to enable achievement of this virtual reality goal. Virtual realities which are created artificially bring about sense-related experiences which may include smell, hearing, touch and sight. The most recent virtual realities are created in different devices which may include computer screens or in special virtual reality headset which are referred by the name head-mounted display.
In many occasions people have argued on what is exactly constitutes the virtual reality. People have given their view on this matter in which some of the views are true but unfortunately others are not. On that note let us look at what exactly is the virtual reality made of.
Images. The virtual reality has images that are mostly in three dimensional and this images appear in a life size depending on how exactly the user can see them from where he is looking from.
Ability to track a user’s motion. This generally is a special motion that involves specific body parts which are the head and the eye. This motion corresponds to the adjustment of the viewed three dimensional images on the user’s display so that is can consequently reflect on the change that is involved in this perspective.
However phenomenal virtual reality has been, it has also experienced various challenges in as much as computer technology is concerned. Some of the biggest challenges facing virtual reality include: finding of more natural ways that will give users a chance to interact more in the virtual environment, developing of better tracking systems and finding a way to decrease the time that it takes to build a virtual space.
