Metamaterial tactile displays with programmable virtual pixels
Overview
This research presents a metamaterial tactile display that overcomes resolution limits of conventional wave-mediated systems by engineering wave transmission through an optimized lattice of resonators. The system uses only eight peripheral actuators to generate localized virtual tactile pixels at any surface location with centimeter-scale resolution, operating within a bandwidth of 75-400 Hz. Four perceptual experiments confirmed that participants could localize, explore, and discriminate multi-pixel patterns comprising transient and sustained vibrations with accuracies ranging from 95.3% to 100%. The work provides engineering methods for designing tactile displays driven by few actuated degrees of freedom, with potential applications in various future domains.
