  • Formulation of tactile Gestalt inducing the comfortableness towards development of haptic device

    <p>To improve the tactile VR technology, we researched the haptic device technology that can provide the material feeling to the palm of hand. We adopted Velvet Hand Illusion (VHI), which is one of the tactile illusion phenomena, and tried to control this sensation. Since it is necessary to create the model of VHI mechanism, we tried to formulate it by applying law of pragnanz in Gestalt theory, which is famous for visual research, to VHI. In the formulation, we focused on the basic VHI stimulus in which two parallel lines (wires) reciprocated between the palms and formulated the VHI intensity by using the phase difference of two parallel lines movement and the speed difference of the two lines as explanatory variables. We conducted the psychophysical experiment and verified this formulation. It was found that our proposed model can explain the relationship between VHI intensity and the stimulus conditions when there was no velocity difference between the two lines. On the other hand, in the condition that included phase and velocity difference, our model explained the relationship between them in only large velocity difference condition. This result suggests that the phase difference and the velocity difference are interrelated, and we should clarify the relationship between them to improve the prediction accuracy of VHI in the future.</p>

  • Precision Enhancement of Fingernail Color Three-axis Tactile Sensor Using CNN

    WATANABE Keisuke, KOMURA Hiraku, OHKA Masahiro

    <p>In our previous study, we developed a fingernail color sensor capable of identifying the magnitude and direction of the force acted on fingers. The prototype is equipped with a small CMOS camera and green LEDs, and collected a dataset of vertical force and shear force acting on the index finger and fingernail color images using an electronic balance and a load cell. The dataset was trained by CNN to estimate forces from the images. In this study we produced individual CNN models, which learned individual fingernail color change data. RMSEs for nine human subjects were 0.12, 0.12 and 0.29 [N] for <i>F<sub>x</sub></i>, <i>F<sub>y</sub></i> and <i>F<sub>z</sub></i>, respectively. RMSEs of <i>F<sub>x</sub></i> and <i>F<sub>y</sub></i> are significantly smaller than those of previous studies.</p>

  • Formulation of tactile Gestalt to express variation in velvet hand illusion caused by out-of-phase cycles of two wires Reviewed

    <p>To develop a tactile display, we focused on the Velvet Hand Illusion (VHI), which is a tactile illusion phenomenon. The most important feature of VHI is that VHI is not generated in one wire but is generated in two or more wires. This means that we recognize the area surrounded by wires as a Gestalt and a smooth surface sensation is generated in the Gestalt. We assume that the VHI mechanism is related to the law of closure and the law of common fate in Gestalt theory. In this paper, we investigate the relationship between VHI and the law of closure by means of variation in a phase difference of two wires’ cyclic movement, and formulate VHI variation, taking into account the law of closure. We try to divide the law of closure into two factors: one of them is a factor of translation and the other is a factor of elasticity. We formulate the tactile Gestalt and verify the validity of this formulation by comparing the result of the psychophysical experiment to the estimation via the formulation. This work shows that the law of closure in the tactile Gestalt consists of the translation factor and the elasticity factor, and the VHI mechanism is described by the formulation of the tactile Gestalt.</p>

  • Enhancement process of Kinesthetic Illusion caused by stimuli of vibrations and movies

    HANAI Tetsuya, KOMURA Hiraku, Masakazu MHonda, OHKA Masahiro

    <p>The kinesthetic illusion (KI) is an illusion that when a suitable vibration stimulus is applied to tendons or muscles, the stimuli tend to feel as if the stimulated tendons or muscles were stretched to move related limbs. In the previous study, we investigated the process of strengthening the moving image in the process of repeating experiments performed by naïve persons who have not experienced the motion illusion so far. An experiment in which a vibration stimulus was applied to the Flexor Carpal Radius (FCR) tendon of the right hand was repeated 5 times to confirm the training effect on KI, which was evaluated by the magnitude estimation method. In the present study, we investigated the effect of the rubber hand illusion (RHI) on the KI with displaying a movie of the wrist extension movement on a display placed in front of the arm.</p>

  • Basic research to elucidate the mechanism of the haptic illusion inducing smoothness

    <p>There is an illusion phenomenon called Velvet Hand Illusion (VHI), in which two steel wires are sandwiched between both hands and rubbed back and forth to create a smooth sensation on the palm. In order to quantitatively evaluate the touch feeling of VHI, a series of psychophysical experiments was performed using the SD method and factor analysis to obtain the psychophysical dimension of tactile perception. As a result, it was found that the difference in VHI sensation between the dot-matrix VHI and the wire VHI was caused by the influence of each stimulating material. It was also clarified that VHI was a phenomenon caused by integration rather than lateral inhibition.</p>

    © 2018 Japanese Society of Tribologists. All Rights Reserved. In this paper, to put this research in context, we first provide a brief survey of the internet of things (IoT) and IoT-like networks. We then introduce our new actuator-sensor network, which is capable of obtaining environmental information through actuator movement configurations which rely on tribological contact. We coin a new word "informotion" which integrates "information" and "motion" to express the abovementioned situation; networks composed of informotion elements are called informotion network systems (INS), the controls of which are based on bio-inspired rules. As an example of INS developed in our laboratory, we introduce an actuator array capable of controlling smooth tactile feeling using the velvet hand illusion. If we accumulate adequate successful findings related to feeling control generated by INS, in future work we will work to increase the ease or comfort for individuals manipulating mechanical or robotic systems by improving the smoothness of tactile feel.
