Technologies like VRML and Shockwave have added more depth to the simulated experiences on the Internet. The future in a helmet. Virtual reality simulations mask reality and provide learners with a direct exposure to a task that normally could not be simulated. As compared to the large scenarios of software-based simulations, virtual reality simulations focus on a specific, complex task that normally might be too dangerous or expensive to simulate in a real world setting. Surgeons can learn how to perform a complex, life threatening surgery before they are faced with the real experience.
Fighter pilots can fly dangerous missions with the aid of a virtual reality flight simulator.
