VR (virtual reality) means “reality that is not real”.
When you wear a VR headset equipped with sensors and a screen, you are surrounded by three-D images, sounds and other sensory information, which creates a super-realistic effect called “presence”. Though you know the sensory information surrounding you is not real, part of your brain believes it is—and acts accordingly.
VR is widely used in education, medicine, entertainment, shopping and travelling.
The barriers include time, cost and technical limitations.
There are endless possibilities.

It is challenging to show the judge and jury what actually happened at a crime scene or at the precise moment of impact during a serious accident. With VR, lawyers are now able to transport them directly into the scene of the crime or accident.
