Modelling and prediction of visual-haptic perception in textiles

Abstract

The study examines the contact and non-contact assessment of textile modalities under three task conditions, namely
visual, haptic, and visual-haptic combination. A comparative analysis shows that the cues perceived by flattened fabrics are
insufficient to stimulate the perception of softness during the purely visual condition. At the same time, the spatial
deformation caused by the action significantly stimulates the perception of softness in the purely haptic state. While in the
visual-haptic dual condition, the spatial deformation causes a folding formation that stimulates the perception of softness by
matching the visual and haptic cue information. The study outcomes are theoretically defined as Perceptual Conflict of
Interest (PCI), which further focuses on the PCI model of fabric perceptual prediction. Accordingly, this study also discusses
different concepts of sensory cue tracking and their impact on cloth modality assessment.
