Live Demonstration: Compressive Subsampling for High-Speed Large-Area Tactile Sensing

This demonstration showcases how compressive subsampling enhances the temporal resolution of large-area tactile sensor arrays, achieving high spatiotemporal fidelity in systems previously limited by slow response times of raster scanning. By applying compressive subsampling, the tactile system can track dynamic interactions, such as a tennis ball ricochet, soft object deformation, and the impact of a fired foam projectile. Participants can interact with several tactile sensor arrays in compressive subsampling and traditional raster-scan modes, providing a direct comparison. Interactive experiments include: (1) indenting soft, rapidly deforming objects, (2) bouncing a tennis ball to observe impact angles, and (3) targeting a sensor ‘dartboard’ with a NERF gun. These hands-on experiences allow visitors to appreciate the ease of implementing compressive subsampling with standard tactile arrays and reveal its potential for high-temporal-resolution applications in robotics and tactile sensing.ISCAS Track: Sensory Circuits and Systems
