The Multimodal Acoustic Trapping Display (MATD) makes use of ultrasound to trap, quickly move and color a particle in mid-air, to create volumetric shapes. Using the pressure delivered by ultrasound, the MATD can also create high-pressure points that our hands can feel and induce air vibrations that create audible sound.
