Humanoid Identification of Fabric Material Properties by Vibration Spectrum Analysis.

As the roughness parameter in the red bars increased, the fine yarn fabric weights of 3.5 to 7.5 oz/yd 2 presented an increasing linear dependence on the roughness properties, while fabrics with thick yarn ranging from 7.5 to 15 oz/yd 2 demonstrated a decreasing trend on fingertip tactile perception, which means the participants were not able to discriminate these three thick-yarn fabrics simply relying on surface roughness only during the fingertip scanning on fabric surfaces.
