Tactile simulation of textile fabrics: Design of simulation signals with regard to fingerprint

This study describes a systematic approach to generate control signals of a tactile simulator to render the touch of textile fabrics. As a friction modulation tactile surface is used, control signals were generated from tribological measurements on real surfaces. Forces were acquired from an artificial finger, with a texture mimicking fingerprints. Then the signals are processed in frequency domain and send as control signal to the tactile stimulator. This paper focusses on the potential benefits of including the fingerprint information in the simulation of fabrics for achieving realistic tactile perception. A sensory analysis with 36 participants was carried out using the generated control signals, and results show a better discrimination without fingerprint information.

Automated summary

This study presents a systematic approach to generating control signals for a tactile simulator that simulate the touch of textile fabrics. By using a friction modulation tactile surface and acquiring forces from real surfaces with artificial finger mimicking fingerprints, control signals are generated and processed in the frequency domain before sending them to the tactile stimulator. The study focuses on the potential benefits of incorporating fingerprint information in fabric simulations to achieve a more realistic tactile perception. A sensory analysis with 36 participants using the generated control signals showed better discrimination without fingerprint information.
