RollingStone: Using Single Slip Taxel for Enhancing Active Finger Exploration with a Virtual ...
summary
RollingStone builds a ball-based single slip taxel under the fingertip driven by two motors and tracked with an HTC Vive tracker to generate 2D slip (speed + angle) and short/long rotational pulses. Prototype uses a 3D-printed sanded ball and epicyclic gearing. Studies use 60% slower / equal / 60% faster slip ratios and a JND staircase to show discrimination independent of hand speed, require larger differences at higher slip, and find an angular JND near 53 degrees. User tests increase realism and enjoyment for two demo apps but not the fast dart game.
