To enter this world you must wear virtual reality glasses, which allow you to view the scenes in front of you and track your movement in them.

 

 

Virtual Reality Features

• Allow free movement within the experience, especially head movement in all directions.
• According to the experience, they respond promptly to the user's actions through glasses and accessories.
• Integrate into VR experience

 

Integrating into the virtual reality

Integrating into the virtual reality experience is an important criterion in its success, as the user must feel that it is really within that virtual world, and to improve that sense uses many technologies and concepts including:

•          Reality content: The elements in the viewer and fit their sizes, materials made of them, and all design details are important and key to a good virtual reality experience.
•         Controls: Some glasses have experiment control buttons, and additional devices are attached to some types of glasses such as those that bind to hands and track their movement, where signals are taken from them to get reactions such as gun shootings such as.
•          Display: It is a part of glasses that specializes in displaying images separately for each eye, and in some types of glasses the display uses a mobile phone that supports virtual reality technology and installs virtual reality software.

•         Frame rate: that is, the frequency of images within the field of vision, the higher this rate the greater the immersion in the experiment, and the more about 60 - 120 frames per second for strong and influential experiments.
•          Motion tracking sensors: When entering a virtual world, you need to be able to sense the moment the head moves its destination, as well as move your hands and body, sometimes associated with VR PlayStation devices.
•          Audio: Providing audio and distributing it in 3D by eyewear earphones or external headphones is a very important part of improving the feeling of fusion in virtual reality.
