CMU launches VR headset plug-in to reproduce the touch of lips and tongue in the Metaverse

 Golden Finance reports that researchers at Carnegie Mellon University have developed a hardware module mounted on the Meta Quest 2 headset that allows users to experience the touch of drinking water, brushing teeth, and kissing in VR. The working principle of the device is to use the thin and light ultrasonic transducer in the newly added module to aim the ultrasonic pulse at the position in and around the user's mouth, and to suspend and move the tiny particles by bombarding the tiny particles with high-energy ultrasonic pulses. In doing so, they create the sensation of touch on the user's lips, teeth, and even their tongue when they open their mouth. (IT House)
