Safely Dive Into Your Fears with Virtual Reality

What makes you afraid? Not like jump-scares in movies or the rush of a roller-coaster, but what are your legitimate fears that qualify as phobias? Spiders? Clowns? Blood? Flying? Researchers at The University of Texas at Austin are experimenting with exposure therapy in virtual reality to help people manage their fears. For some phobias, like arachnophobia, the fear of spiders, this seems like a perfect fit. If you are certain that you are safely in a spider-free laboratory wearing a VR headset, and you see a giant spider crawling across your field of vision, the fear may be more manageable than being asked to put your hand into a populated spider tank.

After the experimental therapy, participants were asked to take the spider tank challenge. Subjects who were not shown VR spiders were less enthusiastic about keeping their hands in the tank. This is not definitive proof, but it is a promising start.

High-end VR equipment and homemade rigs are in the budget for many gamers and hackers, and our archives are an indication of how much the cutting-edge crowd loves immersive VR. We have been hacking 360 recording for nearly a decade, long before 360 cameras took their niche in the consumer market. Maybe when this concept is proven out a bit more, implementations will start appearing in our tip lines with hackers who helped their friends get over their fears.

Kind of the Opposite of a Lightsaber

Lightsabers are an elegant weapon for a more civilized age. Did you ever consider that cutting people’s hands off with a laser sword means automatically cauterized wounds and that lack of blood results in a gentler rating from the Motion Picture Association? Movie guidelines aside, a cauterizing pen is found in some first aid kits, but at their core, they are a power source and a heating filament. Given the state of medical technology, this is due for an upgrade, and folks at Arizona State University are hitting all the marks with a combination of near-infrared lasers, gold particles, and protein matrix from silk.

Cauterizing relies on intense heat, or chemicals, to burn flesh but this process uses less power by aiming the near-IR laser at only the selected areas, and since near-IR can penetrate soft-tissue it goes deep without extra heating. The laser heats the gold, and that activates the silk proteins. Early results are positive but lots of testing remains and it still will not belong in the average first aid kit for a while, lasers and all, but surgery for beloved pets and tolerable humans could have recovery time reduced with this advance.

If this doesn’t sate your need for magical space knight weaponry, we have options aplenty.
