Modelling and Prediction of Visual-Haptic Perception in Textiles

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.
