Tactile Sensations

The use of real textures is the optimal way to present realistic textures in a VR (Virtual Reality) experience. However, a system may require the presentation of numerous objects in a VR scene, making the use of real objects impractical. One way to address this issue is to present visual and tactile texture information simultaneously such that multiple different visual textures are associated with one tactile sensation. This tactile sensation must differ from the visual information only to the extent that the user still perceives the stimuli as consistent. This study examines the consistency required for the simultaneous presentation of visual and tactile sensations for the purpose of reducing the number of necessary real textures in future VR systems. An experiment was conducted using one-dimensional textures (i.e., line gratings), in which participants were asked whether the presented visual texture was finer or coarser than the tactile texture. The results suggest that the relative size of the “permissible range” (the range over which the difference between the visual and tactile sensation is not recognized) is correlated with the spatial period of the real texture.

Abstract The paper presents the validation procedure of the model used in the analysis of the composite blade for the rotor of the ILX-27 rotorcraft, designed and manufactured in the Institute of Aviation, by means of numerical analyses and tests of composite elements. Numerical analysis using finite element method and experimental studies of three research objects made of basic materials comprising the blade structure – carbon-epoxy laminate, glass-epoxy composite made of roving and foam filler – were carried out. The elements were in the form of four-point bent beams, and for comparison of the results the deflection arrow values in the middle of the beam and axial deformations on the upper and lower surfaces were selected. The procedure allowed to adjust the discrete model to real objects and to verify and correct the material data used in the strength analysis of the designed blade.

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.

Socrates' great educational innovation was in ascribing moral worth to the intellectual activity reflectively directed at one's own life. His concept of eudaimonia was so different from the ordinary that talking about it took on sometimes a paradoxical air, as in Apology 30b3. For him, reason is not a tool for attaining goals independently thought worthwhile; rather, rationality itself, expressed in the giving of reasons and the avoidance of contradictions, confers value to goals and opinions. Persons are reasonable, but obviously not the empirical human being. But education is aimed at the empirical man or woman and inevitably employs psychological means. How then is it possible that the result of education should grow out of the depths of each individual and be nevertheless valid for all individuals? In the Symposium, Plato gives Aristophanes the crucial move. Each of us is only half the whole person and we are moved by our desire for what we lack. In this context, to claim that the soul is immortal is to claim-at least-that the soul has a non-empirical dimension, that its real objects are not the objects of desire as such, and that a person's sensible life is not the true basis for the evaluation of his or her eudaimonia. However, in the soul which is not free from contradictions there is no advantage to right but unexamined options. There is in the life of the naïve just an insecurity which is not merely pragmatic. Even if a person never falters to the end of life, this is no more than moral luck. One is still guilty on the level of the logos, and liable to blame and punishment not for what one does, but for what one could have done.

This paper introduces computer vision systems (CVSs), which provides a new method to measure gem colour, and compares CVS and colourimeter (CM) measurements of jadeite-jade colour in the CIELAB space. The feasibility of using CVS for jadeite-jade colour measurement was verified by an expert group test and a reasonable regression model in an experiment involving 111 samples covering almost all jadeite-jade colours. In the expert group test, more than 93.33% of CVS images are considered to have high similarities with real objects. Comparing L*, a*, b*, C*, h, and ∆E* (greater than 10) from CVS and CM tests indicate that significant visual differences exist between the measured colours. For a*, b*, and h, the R2 of the regression model for CVS and CM was 90.2% or more. CVS readings can be used to predict the colour value measured by CM, which means that CVS technology can become a practical tool to detect the colour of jadeite-jade.

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.

Visual Artifacts

Augmented reality (AR) scenes often inadvertently contain real world objects that are not relevant to the main AR content, such as arbitrary passersby on the street. We refer to these real-world objects as content-irrelevant real objects (CIROs). CIROs may distract users from focusing on the AR content and bring about perceptual issues (e.g., depth distortion or physicality conflict). In a prior work, we carried out a comparative experiment investigating the effects on user perception of the AR content by the degree of the visual diminishment of such a CIRO. Our findings revealed that the diminished representation had positive impacts on human perception, such as reducing the distraction and increasing the presence of the AR objects in the real environment. However, in that work, the ground truth test was staged with perfect and artifact-free diminishment. In this work, we applied an actual real-time object diminishment algorithm on the handheld AR platform, which cannot be completely artifact-free in practice, and evaluated its performance both objectively and subjectively. We found that the imperfect diminishment and visual artifacts can negatively affect the subjective user experience.
