Virtual reality in the courtroom: lawyers usually use photos to try to explain the mechanics of a crime or an accident to a jury(陪审团). 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 a VR, lawyers are now able to transport them directly into the scene of the crime or accident.
Virtual reality in sports: athletes use this technology to fine-tune certain aspects of their performance and VR is also used in the design of sporting clothes and equipment,such as running shoes. Virtual reality has been used to improve the audience's experience of a sporting event,too,like walking through a stadium, or even taking part in a game or an event.
