Immersive Mouth Haptics in VR via Headset Ultrasound Phased Array

Vivian Shen, Craig Shultz and Chris Harrison researchers at Carnegie Mellon University have introduced a new approach to enhancing virtual reality experiences by integrating mouth haptics directly into VR headsets. This technology eliminates the need for additional accessories by utilizing a thin, compact beamforming array of ultrasonic transducers. These transducers are integrated into the headset, providing practical and user-friendly mouth haptics that render tactile sensations on the lips, teeth, and tongue.

This enables users to experience a new dimension of VR, where sensations such as taps and continuous vibrations can be felt along three-dimensional paths, all synchronized with graphical feedback to amplify realism and immersion. The research team has showcased a range of sensory demonstrations, including simulations of raindrops, mud splatter, cobwebs, and crawling bugs. While in-air haptics using ultrasonic phased arrays is not a new concept, this marks the first time such technology has been specifically integrated into a headset targeting the oral region, unlocking new and exciting applications in VR.
