“…However, this interpretation is not consistent with the results of psychophysical studies analysing the velocity discrimination of visual [45], [46] or cutaneous [47], [48] stimuli. Moreover, we know from microneurographic recordings the responses of cutaneous mechanoreceptors to superficial brushing of the skin by the same textured stimulus that was used in the present study [27]. No saturation was observed in the frequency of discharges of the cutaneous receptors, up to a brushing velocity of 150°/s”.…”

To further elucidate the mechanisms underlying multisensory integration, this study examines the controversial issue of whether congruent inputs from three different sensory sources can enhance the perception of hand movement. Illusory sensations of clockwise rotations of the right hand were induced by either separately or simultaneously stimulating visual, tactile and muscle proprioceptive channels at various intensity levels. For this purpose, mechanical vibrations were applied to the pollicis longus muscle group in the subjects’ wrists, and a textured disk was rotated under the palmar skin of the subjects’ right hands while a background visual scene was projected onto the rotating disk. The elicited kinaesthetic illusions were copied by the subjects in real time and the EMG activity in the adductor and abductor wrist muscles was recorded. The results show that the velocity of the perceived movements and the amplitude of the corresponding motor responses were modulated by the nature and intensity of the stimulation. Combining two sensory modalities resulted in faster movement illusions, except for the case of visuo-tactile co-stimulation. When a third sensory input was added to the bimodal combinations, the perceptual responses increased only when a muscle proprioceptive stimulation was added to a visuo-tactile combination. Otherwise, trisensory stimulation did not override bimodal conditions that already included a muscle proprioceptive stimulation. We confirmed that vision or touch alone can encode the kinematic parameters of hand movement, as is known for muscle proprioception. When these three sensory modalities are available, they contribute unequally to kinaesthesia. In addition to muscle proprioception, the complementary kinaesthetic content of visual or tactile inputs may optimize the velocity estimation of an on-going movement, whereas the redundant kinaesthetic content of the visual and tactile inputs may rather enhance the latency of the perception.

“…Tangential force was acquired in order to determine the whole force induced by the friction between the slider and the investigated surfaces during dynamic friction contacts. The measurement conditions consisting of the pressure, the slider apparent contact area, the sliding distance and the velocity were chosen relative to fabric tactile conditions [49,50]. The normal load was applied by means of dead weights in order to have a nominal contact pressure of 6.5 kPa.…”

“…Therefore, the yarn surface appearance is closely related to the yarn surface hairiness. [12][13][14][15] Another key factor influencing appearance is yarn unevenness which refers to the mass variation of yarn. It is well known that an uneven yarn usually possesses a large amount of thick and thin regions.…”

In this study, Photoshop software was used to do image analysis on the photos of spun yarns. The result showed that yarn could be divided into two parts: the surface hairs and the stem. Based on this finding, a mathematical model of yarn unevenness was built to analyze the relationship between yarn unevenness and surface hairiness. The relationships among the coefficients of mass variance of the yarn, the stem and the surface hairs, expressed as CV t , CV s and CV h , respectively, were investigated in detail. Results indicate that the CV s of an uneven yarn always coincides with the irregularity of the yarn hairiness. More specifically, the CV t of a yarn cannot be better than those of both yarn hairiness and stem (CV h and CV s ), even if one of them is excessive. It is rare for CV t to be higher than CV s after removal of yarn hairs. In particular, it is irrational for the CV t value to be higher than both CV s and CV h , which prompts a rethinking of the exact distribution of yarn hairs on the yarn body.
