A new VR device lets gamers feel water fountains, mud splatter, and crawling bugs on their lips. But, no, you can’t use it to kiss video game characters.
has come a long way since its bulky and cumbersome beginnings, it often lacks a fundamental element that can create a truly immersive experience: the sense of touch. Fortunately, engineers at Carnegie Mellon University have created a new device that lets you feel sensations on your lips, teeth, and tongue in virtual worlds—so if you can’t brush your teeth in real life, at least you’ll be able to do it in VR.
“Ultrasound waves have peaks and valleys, so we’re able to time it so that when the peak of multiple waves hits the same spot on your face at the same time, you can actually feel it,” Vivian Shen, a robotics PhD student at Carnegie Mellon University, told The Daily Beast. “That’s enough pressure that it actually dents your skin.”about the device with Craig Shultz, a postdoctoral fellow at the Human-Computer Interaction Institute ; and Chris Harrison, associate professor of the HCII.
The team created an array of 64 small ultrasound transducers that focus the waves on the wearer’s mouth, increasing the sensory effects. It’s not perfect. While it worked to create mouth-specific effects like brushing teeth or drinking water, it didn’t work as well for sensations that involved larger parts of the body like walking through cobwebs. However, it does offer some of the most promising results for haptic feedback on a user’s mouth.
