Participation is critical to learning and VR offers multisensory immersive environments that engage students and allow them visualize information. Training and simulation Perhaps the most practical use of VR is in training and simulations. VR simulators are especially useful for training that would otherwise be too expensive or too dangerous. Different training scenarios can be constructed and simply altered for variety. The US Navy uses flight simulators to help train pilots for general navigation as well as special assignments.
Distributed simulations allows users in remote locations to participate in the same environment.
Training tools can also be used for common citizens. For example virtual cars could be used for driver's education classes reducing the expense of cars and insurance and perhaps minimizing costly accidents by inexperienced drivers. Classroom Activities VR offers tools for increased student participation. VR allows natural interaction with information. Instead of reading about foreign places or watching a videotaped program, students can explore new worlds such as foreign countries, ancient times or the human body.
