Tactile Sensations

Individuals with mirror-touch synaesthesia report consciously feeling tactile sensations on their own body when they see another person being touched. They have what may be called vicarious tactile sensations. Vicarious tactile sensations may almost seem unbelievable. How could one feel from the inside someone else’s sensations? First, I will focus on the intersubjective dimension of vicarious touch. In particular, I will examine whether it constitutes a kind of empathy. I will then argue that vicarious touch cannot be taken as evidence in favour of embodied social cognition. Second, I will focus on the intermodal dimension of vicarious touch. I will show how it differs from standard cases of idiosyncratic synaesthesia. I will then argue that it is a by-product of the multimodal nature of non-vicarious bodily experiences.

Tactile Sensations

Tactile sensations of fabrics are the primary property determining the wearing comfort of clothing; however, comprehensive evaluation of the fabric tactile property by considering the flexural buckling of fabrics under high curvature, hysteresis performance and thermal property has not been fully studied, leading to a clear gap between the existing measurement methods and application requirements. Herein, a simultaneous-integrated testing method, namely the Touch Sensation Tester for Fabrics (TST-F) was introduced to evaluate the mechanical–thermal sensory properties of woven fabrics. The introduced instrument used one device with a single mechanical sensor to test various mechanical properties by constructing different deformations of fabrics, and the thermal property was simultaneously measured using an infrared detector array, achieving an efficient characterization of the mechanical–thermal sensation properties of textiles. The measurement capacity and repeatability of the TST-F were statistically analyzed; the measurement indices and their relation with fabric mechanical–thermal sensation properties were also exhibited. Results showed that the TST-F was promising to characterize fabric touch sensations in terms of bending stiffness, compression softness with wrinkling, stretching tightness and thermal comfort by considering the infrared transmission and heat conductivity of textiles.

Intentional Movement

AbstractPeople form coherent representations of goal-directed actions. Such agency experiences of intentional action are reflected by a shift in temporal perception: self-generated motor movements and subsequent sensory effects are perceived to occur closer together in time—a phenomenon termed intentional binding. Building on recent research suggesting that temporal binding occurs without intentionally performing actions, we further examined whether such perceptual compression occurs when motor action is fully absent. In three experiments, we used a novel sensory-based adaptation of the Libet clock paradigm to assess how a brief tactile sensation on the index finger and a resulting auditory stimulus perceptually bind together in time. Findings revealed robust temporal repulsion (instead of binding) between tactile sensation and auditory effect. Temporal repulsion was attenuated when participants could anticipate the identity and temporal onset (two crucial components of intentional action) of the tactile sensation. These findings are briefly discussed in the context of differences between intentional movement and anticipated bodily sensations in shaping action coherence and agentic experiences.

Qualitative And Quantitative Characteristics

Modern consumers attach increasing importance to tactile sensations and the general perception of the surface of fabrics, therefore, the study of the structure and properties of woven textures is an urgent task of textile production. In textile technologies, organoleptic research methods are used mainly, which give a subjective visual and tactile assessment of the surface of the tissues. Therefore, there was a need to develop an instrumental method for determining the texture of fabrics, which was implemented on the basis of the existing method for studying the texture of hard surfaces. It is based on the idea of creating a constant mode of illumination of the object of observation, which is a tissue sample. The proposed method is based on the use of a special optical device for determining the qualitative and quantitative characteristics of textures and is a viewing chamber containing a mechanism for changing the lighting mode and a mechanism for capturing tissue images. For an objective assessment of the state of the surface of the tissues, the invoice indicator is calculated − the invoice coefficient. The implementation of the developed method allows to increase the efficiency of the processes of design-design of fabrics, to predict the appearance of fabrics and to ensure compliance with the texture of the fabric of the model of the garment.

Human Robot Collaboration

Tactile sensations are crucial for achieving precise operations. A haptic connection between a human operator and a robot has the potential to promote smooth human-robot collaboration (HRC). In this study, we assemble a bilaterally shared haptic system for grasping operations, such as both hands of humans using a bottle cap-opening task. A robot arm controls the grasping force according to the tactile information from the human that opens the cap with a finger-attached acceleration sensor. Then, the grasping force of the robot arm is fed back to the human using a wearable squeezing display. Three experiments are conducted: measurement of the just noticeable difference in the tactile display, a collaborative task with different bottles under two conditions, with and without tactile feedback, including psychological evaluations using a questionnaire, and a collaborative task under an explicit strategy. The results obtained showed that the tactile feedback provided the confidence that the cooperative robot was adjusting its action and improved the stability of the task with the explicit strategy. The results indicate the effectiveness of the tactile feedback and the requirement for an explicit strategy of operators, providing insight into the design of an HRC with bilaterally shared haptic perception.
