Ultrasound system targets mouth to create virtual reality haptic effects

3 mins read Communication
Researchers at Carnegie Mellon University have exploited the sensitivity of the mouth to devise a practical new way for people to receive tactile feedback in virtual worlds.

According to Eureka Alert, “Their system uses airborne ultrasound waves to create sensations on the lips, teeth and tongue, and is small and light enough to attach to the bottom of virtual reality (VR) goggles.”

Imagine a VR world that has a drinking fountain in it. "Every time you lean down and think you should be feeling the water, all of a sudden you feel a stream of water across your lips," said Vivian Shen, a second-year Ph.D. student in the Robotics Institute. "It's cool. It makes the experience much more immersive."

According to the media outlet, “Working in the Future Interfaces Group (FIG), Shen and Craig Shultz, a post-doctoral fellow in the Human-Computer Interaction Institute (HCII), have also used the system to create such haptic effects as raindrops, mud splatter and crawling bugs.
