An introduction to Virtual Reality.

Technology has grown leaps and bounds during the last couple of decades. Developers are pushing the boundaries to create tech solutions that are innovative and unique. One such technology that has gained popularity in recent times is Virtual Reality.
It is an artificial environment created with software and presented to the user in a way that the user suspends belief and accepts it as a real environment. It includes three-dimensional images that appear to be life-sized from the user’s perspective. It also has the ability to track a user’s motions and eye movements, and correspondingly adjust images on the user’s display to reflect the change in perspective.
High performance computers and sensory equipment like headsets are used to accomplish this task. The virtual reality world must be large and detailed enough for users to explore and get immersed into. Here are the types of Virtual Reality,
Fully Immersive VR: For a fully immersive VR experience, three things are needed. First, a detailed virtual world to explore or simulation. Second, a powerful computer that can adjust our experience in real time. Third, hardware linked to the computer that immerses the user in the virtual world.
Non Immersive VR: It is an experience where users are not completely immersed in the VR world. For example, a realistic flight simulator on a PC with widescreen, surround sound, joystick and other controls, qualifies as non-immersive VR.
Collaborative VR: Similar to non-immersive VR, the user is not fully immersed in the virtual world. Here in collaborative VR, users can share their experience with other users in the virtual world. Collaboration is likely to become an important feature of VR in the future.
Web Based VR: Developers have built virtual worlds on the web using a technology called Virtual Reality Markup Language. It offers new ways to find and publish information, shop, share thoughts, ideas and experiences with friends online.
The promise of VR has loomed large over the world of computing, but remains largely unfulfilled. Although VR technology is being used in the fields of science, medicine, architecture and military, mainstream adoption of this technology remains to be seen.
