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. -
Biofeedback Games and The Placebo Effect
vrml writes In medicine, it is well-known that sugar pills sometimes produce the same effects as real drugs (Placebo Effect). But could that happen with computers too? The first scientific study of the Placebo Effect in computing, just published by the International Journal of Human-Computer Studies , gives an affirmative answer. The experiment considered affective computing, that is those fancy applications that claim to know user's emotions by detecting physiological parameters with sensors. Researchers took two well-known affective computing systems and used them to control in real-time the state of an avatar that looked more and more nervous as users' stress level increased, and more and more relaxed as it decreased. But they also considered a third system in which, unbeknown to users, the sensors were disconnected from the computer and the avatar state was controlled by a random stream of physiological data instead of the real user's data. Results show that participants believed that the sham application was able to display their stress level. Even worse, only one of the two (costly) affective computing systems produced better results than the placebo. This suggests that evaluations of such novel computer applications should include also a placebo condition, as it is routinely done in medicine but not yet in computer science. -
Future Airline Safety Instructions Will Be Given By Game Apps
vrml (3027321) writes "They revealed the existence of their project only to aviation safety specialists at the recent FAA Conference on Cabin Safety in Philadelphia (PDF). Now a team of Italian researchers from the HCI Lab of the University of Udine has publicly released the first in a set of aviation safety apps on which they are working. Their mission is to propose novel, first-of-their-kind solutions to a well-known problem in aviation safety: passengers lack preparedness about what to do in aircraft emergencies, and do not pay attention or do not clearly comprehend the pre-flight briefings and safety cards used by airlines to instruct them about safety. So the project is re-inventing safety cards and briefings with new media, turning them into games and apps. The first game they decided to release focuses specifically on the 'Brace for impact' position: players can pose the body of their avatar in the 3D airplane cabin and get a personalized simulation of a crash landing . To win the game, you must save your avatar (and yourself)." -
People Become More Utilitarian When They Face Moral Dilemmas In Virtual Reality
First time accepted submitter vrml writes "Critical situations in which participant's actions lead to the death of (virtual) humans have been employed in a study of moral dilemmas which just appeared in the Social Neuroscience journal. The experiment shows that participants' behavior becomes more utilitarian (that is, they tend to minimize the number of persons killed) when they have to take a decision in Virtual Reality rather than the more traditional settings used in Moral Psychology which ask participants to read text descriptions of the critical situations. A video with some of the VR moral dilemmas is available, as is the paper."
