TACTILE SURFACE TEXTURE CHARACTERIZATION METHOD

摘要

Tactile surface texture characterization method comprising at least the following steps: at least one force perceived by a force sensor during a relative displacement of said sensor with respect to a surface to be characterized is measured (211); one or more time and/or frequency parameters of an output signal delivered by said sensor, representative of the previously measured force, are calculated (213); and the value of a tactile descriptor is determined (215) from a plurality of tactile descriptors by applying a calculated transfer function, the transfer function being determined beforehand by regression from a learning database associating, for each descriptor, several values of the tactile descriptor in question with several values of one or more time and/or frequency parameters calculated from measurements carried out by the force sensor on several test surfaces representative of values of the tactile descriptor in question.
