Virtual Reality Games Can Improve Memory Retention of Safety Instructions

vrml writes: Using a virtual reality (VR) headset to experience risky situations as immersive 3D games improves memory retention of passenger safety instructions, according to research published in the IEEE Transactions on Visualization and Computer Graphics, and illustrated by a YouTube video. Researchers recruited occasional flyers: half of them played a VR gaming experience of an airliner water landing and evacuation, while the other half studied a real airline safety card. After one week, passengers who had studied the safety card suffered a significant loss of knowledge, while passengers who had played the VR game fully retained the safety knowledge gained. The research group has now made available its emergency water landing experience also for the Oculus Rift.

      It's probably easier to simulate the practical environment and mechanics of an aircraft than a hang glider, in which you're directing the flight controls with your body instead of a mechanical flight stick or yoke. Unless you've got a virtual hang glider controller hooked up in a large virtual environment, I can see how it might not work so well. On the contrary, you can create a reasonable flight simulator experience with a PC and some reasonably inexpensive accessories.

      In nearly all other forms of flight, simulators are used extensively to good effect, so I'd be careful about generalizing the lessons learned by one hang-gliding instructor.

      Basic flying skills are taught hands on on real aircraft (eg: C-172), developing up to aircraft like Piper Seminole for multi-engine certification. Lots of time is spent flying these aircraft before ever being in the airline industry.

      Where Simulators are a big help in the airline industry, to experienced pilots that know how to fly a plane, is:
      -Cost: Operating an empty 737 or A330 for training purposes only would be prohibitively expensive. Simulators allow more crew to get training at lower cost.
      -Procedure based training: Drilling over and over checklists. Checklists for normal operation, checklists for emergencies (eg: engine failure). By simulating these in the safety of a simulator, with a cockpit laid out exactly like the real plane (Not VR helmet, and not Microsoft Flight Sim with a keyboard), pilots will already be familiar with the scenario if faced with it in real life, and know where to reach for controls.
