# Fabric Tactile Prediction Method Based on Spider Diagram

## TL;DR

This study develops a tactile prediction model for fabrics using a spider diagram to link physical properties with subjective touch sensations.

## Contribution

A novel tactile prediction model for fabrics using a spider diagram and objective physical properties linked to subjective evaluations.

## Key findings

- Subjective tactile evaluations were collected from volunteer participants for three types of fabric sensations.
- A spider diagram was created to normalize and compare five physical properties across 15 fabric samples.
- The model successfully links physical properties to subjective tactile perception for reliable tactile prediction.

## Abstract

The detection and quantification of fabric tactile sensations are crucial in textile production and marketing as they are closely linked to textile comfort and serve as key criteria for consumers when selecting fabrics. Previous studies have predominantly focused on measuring the physical properties of fabrics, often neglecting correlations between these parameters and tactile sensations. This oversight complicates customers’ ability to assess the tactile experience of fabrics during online purchasing. This study first obtained subjective evaluations of three types of fabric tactile sensations through experiments involving volunteer participants. Subsequently, five objective physical properties that characterize fabric tactile properties were proposed and experimentally tested on 15 fabric samples categorized by yarn weight, weave pattern, and material. A fabric tactile spider diagram was created by normalizing the values of the five physical properties across the 15 fabric samples. The grading of the physical properties was then performed based on the proposed evaluation index. These spider diagrams were compared with the subjective evaluation results to analyze the physical properties that most significantly influenced subjective perception, ultimately leading to the development of a highly reliable fabric touch prediction model.
