Noisy vibrotactile signals transmitted during tactile explorations of anobject provide precious information on the nature of its surface. Linking theproperties of such vibrotactile signals to the way they are interpreted by thehaptic sensory system remains challenging. In this study, we investigatedhumans' perception of noisy, stationary vibrations recorded during explorationof textures and reproduced using a vibrotactile actuator. Since intensity is awell-established essential perceptual attribute, an intensity equalization wasfirst conducted, providing a model for its estimation. The equalized stimuliwere further used to identify the most salient spectral features in a secondexperiment using dissimilarity estimations between pairs of vibrations. Basedon dimensionally reduced spectral representations, linear models ofdissimilarity prediction showed that the balance between low and highfrequencies was the most important cue. Formal validation of this result wasachieved through a Mushra experiment, where participants assessed the fidelityof resynthesized vibrations with various distorted frequency balances. Thesefindings offer valuable insights into human vibrotactile perception andestablish a computational framework for analyzing vibrations as humans do.Moreover, they pave the way for signal synthesis and compression based onsparse representations, holding significance for applications involving complexvibratory feedback.
