This study investigates the influence of an area of warm stimulation on the waist to efficiently design a device that can provide higher thermal comfort to users. A device that could apply warmth on the waist by using four thermal units that utilize the Peltier element was developed. The experiment performed to determine spatial perception showed that the participants could not recognize a difference in the spatial pattern of stimulation using the developed device correctly. Furthermore, the results of experiments that evaluated the perceived intensity and the comfort indicated that a larger area of warm stimulation increased not only the perceived intensity but also the thermal comfort, whereas the intensity of the stimulation had less effect on the thermal comfort than the perceived intensity. Therefore, it is better to increase the area rather than the intensity of warm stimulation to improve the comfort provided by the thermal device., 2018, 10894, 10894, 106, 113, International conference proceedings
  • Refereed, Lecture Notes in Computer Science (including subseries Lecture Notes in Artificial Intelligence and Lecture Notes in Bioinformatics), Springer Verlag, Relative sensation of wetness of different materials, Mai Shibahara; Katsunari Sato; Astrid M. L. Kappers, Previous studies have already shown that an illusion of wetness can be elicited by touching a dry cold object. Both metal and cloth are materials that can cause this illusion. This paper investigated the relative sensation of wetness caused by some other materials at the same low temperature. Participants were presented with stimulus pairs of different materials such as metal, PVC, acrylic and paper, and they had to judge which of the two felt wetter. From the results we obtained a scale of relative wetness sensation. Subsequently, several physical properties of the materials were measured. We conclude that materials that cause the human skin to cool quickly, cause the stimulus to feel relatively wet. Interestingly, also stickiness can lead to a sensation of relative wetness, even when presented at room temperature., 2018, 10893, 10893, 345, 353, International conference proceedings

The module is composed of two different components miniaturized vibrator and four units of Peltier devices. The dimension of the vibro-thermal tactile feedback device is 16 × 32 × 7 mm, which is small enough for attaching to fingerpad.

  • Refereed, Lecture Notes in Electrical Engineering, Springer Verlag, Expression of 2DOF fingertip traction with 1DOF lateral skin stretch, Vibol Yem; Mai Shibahara; Katsunari Sato; Hiroyuki Kajimoto, To reproduce the sensation of rubbing on a surface, we need to laterally stretch the skin of the fingertip with two degrees of freedom (2DOF). Unfortunately, it is difficult to develop a compact 2DOF device for the fingertip because at least two actuators are required. However, if we can perceive the rubbing sensation regardless of the skin stretching direction, a device with 1DOF is sufficient. This study used a lateral skin deforming device with 1DOF, and evaluated the realism of the sensation. We found that even when the direction of skin stretch was opposite or perpendicular to the finger movement, users still perceived it as natural., 2018, 432, 21, 25, International conference proceedings
  • Refereed, IEEE TRANSACTIONS ON HAPTICS, IEEE COMPUTER SOC, Physical-Perceptual Correspondence for Dynamic Thermal Stimulation, Hsin-Ni Ho; Katsunari Sato; Scinob Kuroki; Junji Watanabe; Takashi Maeno; Shin'ya Nishida, Thermal displays have been applied in various haptic applications, from material simulation to interpersonal communication; however, there is insufficient knowledge about the temporal processing in human thermal sense to provide a knowledge basis for thermal display design. In this study, we investigated the physical-perceptual correspondence for dynamic thermal stimulation to shed a light on the temporal processing of human thermal sense. In the experiments, participants reported subjective timings of the temperature onset and temperature peak of continuous temperature changes applied to the thenar eminence. We found that the physical-perceptual correspondence was not consistent for warm and cold stimulations. For warm stimulation, the subjective experience always came after the corresponding physical event. On the other hand, for cold stimulation, while the subjective onset always lagged the physical onset, the subjective temperature peak preceded the physical temperature peak. We analyzed these results in the framework of linear systems theory. The results suggest that the senses of warmth and cold have distinct temporal filtering properties, with the sense of cold being more transient than the sense of warmth. These findings advance our knowledge regarding temporal processing in human thermal sense and serve as a basis for thermal display design., Jan. 2017, 10, 1, 84, 93, Scientific journal

    This paper investigates valuable functions for the fabric products that utilizes recently developed technologies to clarify a guideline for development of the products and technologies. The authors applied the brainstorming method and KJ method to systematically gather the functions for the fabric products and classified into 10 categories consisting of 40 functions. Furthermore, to estimate the requirements of each function, the authors applied the 10 categories to Maslow's hierarchy of needs. The authors carried out a questionnaire survey that asked requirements for each function toward university students. As a result, we confirmed that the Maslow's hierarchy of needs is effective to estimate the requirements for the functions of fabric products: the lower-order the functions such as health and defense are, the higher the requirements become.

  • Refereed, Transactions of the Society of Instrument and Control Engineers, The Society of Instrument and Control Engineers, Enhancement of Blood Flow to Support Exercise Using Local Thermal Stimulation for Ankle, SATO Katsunari; MIZUGUCHI Sayaka, The enhancement of blood flow is effective to improve performance of exercise and reduce fatigue after it. This paper proposed a wearable thermal device that enhances the blood flow by alternative hot and cold stimuli at a local point of the ankle. The previous studies showed that thermal stimuli using waters is effective to enhance the blood flow, and our compact device achieved it by simple method using a Peltier device. At first, we evaluated whether the thermal stimuli for a local point on ankle could enhance the blood flow or not comparing with a case of mechanical pressure stimuli and actual exercise. Then, we investigated that how the previous thermal stimulus influences the performance of exercise taking pedaling motion. The results of experiments showed that the proposed thermal device can enhance the blood flow enough so that it improved persistent of exercise and reduced subjective hardness during pedaling motion., 2017, 53, 3244-250, 244, 250
  • Refereed, Transactions of the Virtual Reality Society of Japan, THE VIRTUAL REALITY SOCIETY OF JAPAN, Effect of the Direction of Finger Pad Skin Stretch on Reproduction of Tracing Sensation, Shibahara Mai; Yem Vibol; Sato Katsunari; Kajimoto Hiroyuki,

    To reproduce tracing sensation on a surface, it was considered to require a skin-deformation device with at least two degrees of freedom. In contrast to such a conventional design, we hypothesized that the direction of shear deformation does not affect the realistic of tracing sensation, thus the device mechanism can be simplified. The experimental results showed that even when the direction of skin deformation was opposite or perpendicular to the finger movement, participants still perceived it as natural. Therefore, we concluded that when the finger moves, we do not need to precisely reproduce the direction of skin deformation.

  • Refereed, Transactions of the Virtual Reality Society of Japan, THE VIRTUAL REALITY SOCIETY OF JAPAN, Presentation of Thermal Sense to Finger Pad through thermal Stimulation on Finger Side, Sato Katsunari,

    This paper proposes a thermal display that can present a virtual thermal sensation to the finger pad using thermal stimuli on the side of the finger. The proposed method could help realize the thermal augmentation of real objects or simplify the design of a haptic display. This paper investigates the effect of proposed method in terms of perceived strength and reaction time of the virtual thermal sensation. The results indicate that a tactile stimulation is required for a virtual thermal sensation to be perceived on the finger pad similar to that observed in the thermal referral phenomenon. Furthermore, the vibrotactile stimulation appears to improve both the perceived strength and the reaction time.

  • Refereed, Transactions of the Virtual Reality Society of Japan, THE VIRTUAL REALITY SOCIETY OF JAPAN, Haptic-Through Systems: Tactile Information Transmission through Clothing, Kamiya Tomoki; Kajimoto Hiroyuki; Sato Katsunari; Yanagida Yasuyuki,

    It has been reported that haptic perception ability is diminished by wearing gloves and other clothing. To resolve this problem, we propose a transmission system of haptic information that consists of a haptic sensor on the surface of the clothing and a haptic display between the clothing and the skin. Using this system, haptic information is transmitted as if it penetrated the clothing. We named this concept "Haptic-Through", and the system having this function "Haptic-Through Systems" collectively. In this paper, as an example of Haptic-Through Systems, we implemented and evaluate a finger-mounted Haptic-Through System.

  • Refereed, Transactions of Japan Society of Kansei Engineering, Japan Society of Kansei Engineering, Effects on Haptic Impression Associated with Odor of Japanese Cypress to Haptic Sensation of Wood and Plastic Materials, INOUE Hikari; SATO Katsunari, This paper investigates how the odor stimulation changes the haptic sensations of materials. The authors examined associated haptic impression with odor of Japanese cypress and the actual haptic sensations of 4 wood (including cypress material) and 4 plastic materials with/without odor stimulation employing the semantic differential (SD) and rating scale methods to evaluate physical properties and impressions of the sample materials, respectively. The emotion coming from the materials and the odor were also examined using rating scale. The authors calculated the distance between the associated haptic impressions with cypress odor and the actual haptic sensation of the material, and compared the effect of odor stimulation. The results showed that the odor stimulation has the effect to make the actual haptic sensation related to the physical properties close to the associated haptic impression with the odor., 2017, Scientific journal

    Just as we select suitable clothes for specific situations, we also consider which fragrance will be suitable and emphasize the impression of the clothes we wear. The purpose of this study is to investigate the method used to select a fragrance as suitable or unsuitable for particular clothing. We examined the degree of conformity of the impressions of each combination among five pieces of clothing and six fragrances and checked the impression factors and individual preferences of each to discuss what affects the degree of conformity. We investigated some models using Covariance Structure Analysis based on the hypothesis that not only the similarity of factors but also preferences and impressions of clothes and fragrances affect the degree of conformity. As a result, we found that some combinations show high degrees of conformity of impression corresponding with the similarity of factors and the factor scores of clothes and fragrances.

This paper investigated whether controlling the surface temperature and softness of a cloth could reproduce the wet sensation or not. Participants scored their feelings after touching the cloth with different temperatures and softness.

The results confirm that users perceive hot or cold sensation even if there are no thermal stimuli on the finger pad by presenting stimuli to the finger side. Furthermore, the proposed method successfully improves thermal sensation by applying the same thermal stimuli to the finger side as the sensation on the finger pad., 2016, 9774, 512, 520, International conference proceedings

Furthermore, we clarify the current problems of the conductor such as the variation in the electrical resistance with time and the bending characteristics., 2014, 8619, 191, 197, International conference proceedings
  • Refereed, SENSORS AND ACTUATORS A-PHYSICAL, ELSEVIER SCIENCE SA, Droplet mu TAS using electro-conjugate fluid - Feedback position control of multiple droplets in flow channel matrix, Yoko Abe; Kenjiro Takemura; Katsunari Sato; Shinichi Yokota; Kazuya Edamura, This paper proposes a novel droplet transportation method for micro total analysis system (mu TAS), which we called as an active flow channel matrix, using an electro-conjugate fluid (ECF). The ECF is a kind of functional fluid, which generates a powerful flow when applying a high voltage across the electrodes. A droplet that is placed into the channel may move in any direction according to the channel flow generated by the ECF. Therefore, in order for the multiple droplets from different channels to be merged, they are moved to reach the desired intersection. According to this concept, we developed a prototype of the active flow channel matrix. Then, we measured two droplets' position and controlled the position of them by using image processing technique. The experimental results demonstrated the possibility of our concept for mu TAS.

  • Refereed, Journal of Robotics and Mechatronics, Fuji Technology Press, Presentation of rapid temperature change using spatially divided hot and cold stimuli, Katsunari Sato; Takashi Maeno, We propose a thermal display that presents a rapid temperature change using spatially divided hot and cold stimuli. The display exploits two characteristics of human thermal perception: spatial summation and the adapting temperature. Experimental results confirmed that users perceived separate individual thermal stimuli as a single stimulus because of spatial summation. Our thermal display successfully made the skin simultaneously more sensitive to both hot and cold stimuli by using spatially divided hot and cold stimuli, each of which separately adjusts the adapting temperature so that it enables users to perceive thermal sensation rapidly. The thermal display that we fabricated enabled users to perceive a different temperature sense by changing the temperature of hot and cold stimuli., 2013, 25, 3, 497, 505, Scientific journal
  • Refereed, 2013 IEEE VIRTUAL REALITY CONFERENCE (VR), IEEE, Haptic Transmission System to Recognize Differences in Surface Textures of Objects for Telexistence, Tadatoshi Kurogi; Masano Nakayama; Katsunari Sato; Sho Kamuro; Charith Lasantha Fernando; Masahiro Furukawa; Kouta Minamizawa; Susumu Tachi, In this paper, we propose a haptic transmission system for telexistence to improve the ability to sense the presence of remote objects. This system can transmit information about the existence and surface textures of objects in remote locations. The system consists of a conjugated haptic sensor and display. The sensor on the robot's finger detects the pressure, vibration, and temperature of a remote object, and the display provides above information on the operator's finger. Based on this information, the operator can understand what he/she is touching and whether its surface is hard or soft, cold or hot, and smooth or rough. With the use of our system, the operator can recognize the difference between objects such as silk and denim., 2013, 137, +, International conference proceedings
  • Refereed, ISWC 2013 - Proceedings of the 2013 ACM International Symposium on Wearable Computers, Thermon-thermo-musical interface for an enhanced emotional experience, Shimon Akiyama; Katsunari Sato; Yasutoshi Makino; Takashi Maeno, This report proposes a thermal media system, ThermOn, which enables users to feel dynamic hot and cold sensations on their body corresponding to the sound of music. Thermal sense plays a significant role in the human recognition of environments and influences human emotions. By employing thermal sense in the music experience, which also greatly affects human emotions, we have successfully created a new medium with an unprecedented emotional experience. With ThermOn, a user feels enhanced excitement and comfort, among other responses. For the initial prototype, headphone-type interfaces were implemented using a Peltier device, which allows users to feel thermal stimuli on their ears. Along with the hardware, a thermal-stimulation model that takes into consideration the characteristics of human thermal perception was designed. The prototype device was verified using two methods: the psychophysical method, which measures the skin potential response and the psychometric method using a Likert-scale questionnaire and open-ended interviews. The experimental results suggest that ThermOn (a) changes the impression of music, (b) provides comfortable feelings, and (c) alters the listener's ability to concentrate on music in the case of a rock song. Moreover, these effects were shown to change based on the methods with which thermal stimuli were added to music (such as temporal correspondence) and on the type of stimuli (warming or cooling). From these results, we have concluded that the ThermOn system has the potential to enhance the emotional experience when listening to music.Copyright © 2013 ACM., 2013, 45, 52, International conference proceedings

The Telesar4 system was implemented as a prototype, and feasibility experiments confirmed that the system provided the remote participant with the ability to see the event venue and local participants as naturally as though at the event; i.e., a realistic wide-range stereo view of the event venue was observed in real time. It was also confirmed that face-to-face communication was provided, as the local participants at the event were able to see the face and expressions of the remote participant in real time. It was further confirmed that the system allowed the remote participant not only to move freely about the venue by means of the surrogate robot but also to perform some manipulatory tasks such as a handshake and several gestures., 2012, 17, 1, 11, 21, Scientific journal
  • Refereed, 6TH INTERNATIONAL CONFERENCE ON SOFT COMPUTING AND INTELLIGENT SYSTEMS, AND THE 13TH INTERNATIONAL SYMPOSIUM ON ADVANCED INTELLIGENT SYSTEMS, IEEE, EffectON-enriching impressions of motions and physically changing motions via synchronous sound effects, Shimon Akiyama; Katsunari Sato; Yasutoshi Makino; Takashi Maeno, In this paper, we introduced EffectON, a system that enables users to hear sound effects, i.e., audio feedbacks, of their routine motions. We believe that there are three main benefits of people hearing sound effects corresponding to their motions: sonification of the motion or action, modification of the impression of motions, and a physical change in the motion itself. The unique hypothesis of this research proposes that by changing the condition of the sound effect itself and its presentation, all the three benefits would have different characteristics. These benefits must be highly subject to the way sound is presented, i.e., it would depend on parameters of sound, such as the length, volume, timing, and type, as well as the conditions of motion chosen (e.g., types, sites, parameters, etc.). We have developed two prototype devices: a step-based device and a knee-bend based device. The report first focuses on the third benefit of physically changing the users' motion by changing the "duration" of sound effects. To be specific, the step-based device is mainly used in this report to focus on the "gait," and four sound effects of two different types and durations were implemented to see if the walking speed of the subjects would change on hearing them. The experimental result showed that users naturally walk faster on hearing shorter duration sounds. This implies that there is great potential for naturally controlling or inducing a certain motion by appropriately choosing the sound effects that correspond with the motion., 2012, 856, 860, International conference proceedings
  • Refereed, Haptics Symposium 2012, HAPTICS 2012 - Proceedings, Presentation of thermal sensation through preliminary adjustment of adapting skin temperature, Shimon Akiyama; Katsunari Sato; Yasutoshi Makino; Takashi Maeno, Since the sense of touch inherently involves thermal phenomena, presenting thermal sensation on a handheld man-machine interface holds great potential. However, when users are in tactile contact with a device, it is difficult to enable them to perceive a thermal sensation at the same time as the relevant electronic event because the thermal responses of both a thermal display and the human skin are slower than mechanical or electrical responses. In order to overcome this problem, a suitable method for the presentation of rapid changes in temperature is required. While using a highly efficient thermal device and applying a large amount of energy may be one possible approach to speeding up thermal perception, the authors propose an alternative approach that uses a preliminary adjustment of the skin's adapting temperature without increasing the intensity of the thermal stimuli. The experimental results indicate that the proposed method is applicable for the improvement of thermal perception and, thereby, the response time. © 2012 IEEE., 2012, 355, 358, International conference proceedings
  • Refereed, Lecture Notes in Computer Science (including subseries Lecture Notes in Artificial Intelligence and Lecture Notes in Bioinformatics), Contact force and finger angles estimation for touch panel by detecting transmitted light on fingernail, Yoichi Watanabe; Yasutoshi Makino; Katsunari Sato; Takashi Maeno, In this paper, we propose a new method that can estimate a normal force and finger posture for touch panel devices by measuring transmitted light on fingernail. When a user touches a light source with their finger, the light (mainly red component) can be seen at a fingernail since the red light can go through the finger tissue. Based on this characteristic, we can estimate the manipulatory force by detecting the light intensity at the fingernail because the intensity of the transmitted light increases according to the applied force. We can also estimate the relative angles of the finger to a touch panel device. Even though the transmission through the finger tissue is diffusive, we can know the movement of the light source under the finger with a camera attached onto the fingernail. Therefore, a transient trajectory pattern of the light source is useful for estimating the relative direction between the finger and the device. When the posture of the finger is estimated, we can use "rotate" motion for manipulation. Our proposed method can be used as a new input device. © 2012 Springer-Verlag., 2012, 7282, 1, 601, 612, International conference proceedings

Experimental results confirmed that users perceived separate individual thermal stimuli as a single stimulus when the thermally stimulated area was small because of the low spatial resolution. The spatially distributed warm and cold stimuli enabled users to perceive the thermal sensation rapidly even if the cold stimulus was suddenly presented after the warm stimulus and vice versa. Furthermore, our thermal display successfully made the skin more sensitive to both warm and cold stimuli simultaneously by using spatially divided warm and cold stimuli, each of which separately adjusts the adapting temperature. © 2012 Springer-Verlag., 2012, 7282, 1, 457, 468, International conference proceedings

The thermo sensitive ink is employed to measure temperatures of the sensor surface on the basis of its color, which changes according to its temperature. The proposed method can be implemented in a simple structure so that we can integrate it with the finger-shaped GelForce technology that measures tactile information in terms of surface traction field. We implemented prototype sensors and confirmed that the proposed method can measure difference in temperature or material of objects based on the time response of measured temperature., 2011, 16, 3, 391, 398, Scientific journal

  • Refereed, IEEE TRANSACTIONS ON HAPTICS, IEEE COMPUTER SOC, Finger-Shaped GelForce: Sensor for Measuring Surface Traction Fields for Robotic Hand, Katsunari Sato; Kazuto Kamiyama; Naoki Kawakami; Susumu Tachi, It is believed that the use of haptic sensors to measure the magnitude, direction, and distribution of a force will enable a robotic hand to perform dexterous operations. Therefore, we develop a new type of finger-shaped haptic sensor using GelForce technology. GelForce is a vision-based sensor that can be used to measure the distribution of force vectors, or surface traction fields. The simple structure of the GelForce enables us to develop a compact finger-shaped GelForce for the robotic hand. GelForce that is developed on the basis of an elastic theory can be used to calculate surface traction fields using a conversion equation. However, this conversion equation cannot be analytically solved when the elastic body of the sensor has a complicated shape such as the shape of a finger. Therefore, we propose an observational method and construct a prototype of the finger-shaped GelForce. By using this prototype, we evaluate the basic performance of the finger-shaped GelForce. Then, we conduct a field test by performing grasping operations using a robotic hand. The results of this test show that using the observational method, the finger-shaped GelForce can be successfully used in a robotic hand., Jan. 2010, 3, 1, 37, 47, Scientific journal

Surfaces such as canvases or walls, provided the tactile sensations of the drawing surface while painting. However, this tactile experience has got lost because of advances in computer graphics software. Besides, a conventional multi-touch interface [1] can not provide tactile sensation. We propose a novel interactive painting interface called "Colorful Touch Palette" that may help us to rediscover our creativity. The user can touch the canvas having the electrode, select or blend tactile textures of their choice, draw a line, and experience the tactile sensations of painting as shown in Figure 1. Various tactile textures can be created by blending textures as paints. This interface can be used to design complex spatial tactile patterns for haptic-friendly products. Moreover, this system can be potentially used to create novel tactile paintings. © ACM 2010., 2010, International conference proceedings

As such, we seek the representation of the distribution of force vectors via an electrotactile display. The electrotactile display directly activates nerve fibers connected to mechanoreceptors, thereby representing a tactile sensation. The system has a simple structure, is easily controlled and, it has seen a number of different applications. However, the majority of the conventional electrotactile displays only present a symbolic sensation of contact. In this paper, we propose the design of electrotactile stimulation for the distribution of force vectors, on the basis of the concept of "tactile primary colors". Considering that a selective stimulation of mechanoreceptors enables the representation of the distribution of force vectors, we evaluate the proposed design in terms of the distribution, magnitude, and direction of a force vector. The results demonstrate that the proposed design is a viable approach to representing the distribution of force vectors. ©2010 IEEE., 2010, 121, 128, International conference proceedings

Recently there has been a substantial need and interest in haptic displays, which can provide realistic and high fidelity physical interaction in virtual environment. The aim of our research is to implement a wearable haptic display for presentation of realistic feedback (kinesthetic stimulus) to the human arm. We developed a wearable device FlexTorque that induces forces to the human arm and does not require holding any additional haptic interfaces in the human hand. It is completely new technology for Virtual Reality that allows user to explore surroundings freely. The concept of Karate (empty hand) Haptics proposed by us is opposite to conventional interfaces (e.g., Wii Remote, SensAble's PHANTOM, SPIDAR [Murayama et al. 2004]) that require holding haptic interface in the hand, restricting thus the motion of the fingers in midair., 2009, International conference proceedings

This grip-type haptic display enables us to control a virtual hand and perceive haptic information based on a reactive force and a spatially distributed tactile feedback. Because this proposed display does not need any actuators to produce the reactive force, a simple haptic display is developed. In a grip-type haptic display, it is difficult to perceive the finger position because of the fixed position of the user's fingers. However, we consider that it is possible to perceive the finger position by means of the effort exerted. Therefore, we performed an experiment to discriminate the applied force and confirm that the force discrimination threshold was sufficiently small. Then, we constructed a one-fingered prototype using an electrotactile display. Using this prototype, we qualitatively confirmed that the reactive force with the spatially distributed tactile feedback can produce dynamically changing haptic information. © 2009 SICE., 2009, 1089, 1094, International conference proceedings

Powerful haptic displays are large and heavy, interfering with movement in the virtual environment. Here, we focus on an illusion called pseudo-haptic feedback, which provides the results of haptic feedback using only visual impressions. Since pseudo-haptic feedback is known to be inappropriate for applications requiring strong force, a combination of pseudo-haptic feedback and real haptic feedback is proposed for a compact haptic display. This study examines the effectiveness of this combination by comparing the stiffness of two walls. Pseudo-haptic and real haptic feedbacks are applied to one wall, and only real haptic feedback is applied to the other wall. The results verify that the magnitude of the force perceived with the application of a combination of pseudo-haptic and real haptic feedbacks is greater than that of the force perceived by the application of only real haptic feedback. © 2009 SICE., 2009, 4332, 4337, International conference proceedings

Therefore, we have developed a new type of finger-shaped haptic sensor that can measure a three-dimensional force vector field over a contact surface. The sensor consists of a transparent elastic body, two layers of internal blue and red markers, and a CCD camera to capture the movements of the markers. Using the elastic theory, we can calculate the force vector field from the captured movements of the markers. However, the elastic theory cannot be applied to the finger-shaped sensor because of its complicated shape. Therefore, we use actual measurements for the calibration in order to develop a prototype of the sensor. Then, we evaluate its basic performance.

Since the flexible electrode substrate fits and deforms along with a curvature surface of the fingertip, the user doesn't feel undesirable pressure sensation from the electrode substrate and perceives the shape of a real object when they touch it through the substrate. This indicates that the developed electrotactile display can naturally attach surface textures on a real object. The experimental result indicated that the users correctly recognized the difference in position between an edge of a real object and that of an electrotactile stimulus, i.e., they precisely recognized spatially distributed tactile information from both the real object and the electrotactile display., 22 May 2013, 2013, "2A1, A13(1)"-"2A1-A13(4)"

In order to address this issue we designed and developed TELESAR V, with a 5 DOF torso and a 7 DOF arm attached to it so that the slave robot can have 6 DOF point of vision and 6 DOF arm endpoint accuracy with operator's posture. This structure enables the operator to freely move in his space and experience his extended bodily border while operating the robot and perform manipulatory task remotely.

Previously, several types of force feedback devices have been developed, however, an ungrounded force feedback devices are still not in practical use. Ungrounded force feedback devices do not require any origin of a reaction force outside an operator, which extends the range of working space to the infinite. Therefore, it is technically competent for a mobile interface. The present study develops a prototype of an ungrounded force feedback device using a gyroscopic torque. This prototype uses a Control Moment Gyro (CMG) as an actuator unit that generates a gyroscopic torque.

The two prototypes can detect contact condition of shoes to the ground and bending angle of knees respectively. These information can be used to add many kinds of sound effects to make users know their body conditions or to entertain them. For example, if every single steps of a walk emits funny sound, tough rehabilitation might be more enjoyable. The devices may change user's motion from bad manner to appropriate way with fun., 27 May 2012, 2012, "2P1, N03(1)"-"2P1-N03(2)"

  • ロボティクス・メカトロニクス講演会講演概要集, The Japan Society of Mechanical Engineers, 1A2-E02 Numerical Estimation of Mechanoreceptor Response to Represent Tangential Force using Electrotactile Stimulation, SATO Katsunari; Tachi Susumu, A tangential force on a fingertip improves the stability of a given operation in telexistence or virtual reality systems. This study seeks the representation of tangential force via an electrotactile display. A selective stimulation of mechanoreceptors has a potential to represent a natural tactile sensation using the compact electrotactile display. To represent the tangential force using the electrotactile stimulation, responses of RA and SAI receptors should be estimated. In this paper, we focused on a stick state when a tangential force is applied to a fingertip. We constructed a two-dimensional fingertip model and numerically estimated responses of each receptors using finite element method (FEM). Based on the results of FEM, we constructed a signal of electrotactile stimulation to represent the stick state., 2010, 2010, "1A2, E02(1)"-"1A2-E02(4)"

Slave robot of TELESAR3 consists of a 6 DOF robot head and pneumatic robot arms, is able to more faithfully represent large motion range and compliance of human. Master system of TELESAR3 is constructed by wearable sensor tubes, called Flexible Sensor Tube (FST), operator can possess virtually limitless freedom of movement.

In this study, we investigated the relation between the threshold that subjects can recognize time delay and the threshold that subjects are influenced by time delay. We evaluated postural sway of moving subjects based on the center of gravity and head position. At the same time, the objective rating by the questionnaire to the subjects. The results suggest that the area of the delay with the influence on postural sway exists though the delay cannot be recognized for non-expert subjects., 2010, 2010, "1A1, F28(1)"-"1A1-F28(4)"
  • ロボティクス・メカトロニクス講演会講演概要集, The Japan Society of Mechanical Engineers, 2A2-J12 Perception of Force based on Muscle Activities of Fixed Finger, SATO Katsunari; KAWAKAMI Naoki; Tachi Susumu, In this study, we propose the novel grip-type master hand that uses grasping force to control a robotic (or virtual) hand. The grip-type master hand enables us to control grasping force of the robotic hand. Furthermore, because proposed method doesn't need any actuators to produce reactive force, a simple haptic display seems to be archived. In the grip-type master hand, perception of finger position seems to be difficult because the finger position of the user is fixed. However, we consider that perception of finger position is possible from the muscle activities. Therefore, we perform a discrimination experiment of applied force by a fixed finger. From the result, we confirm the possibility of perception of finger position from muscle activities., 25 May 2009, 2009, "2A2, J12(1)"-"2A2-J12(3)"

In previous optical force sensors, an elastic body and cameras are fixed together. Contrarily, on our system, users can move tile-shaped elastic bodies freely on a flat face. The sensing process is as follows : first, the system detects its position, rotation and ID of each interface face by position markers attached on their bottom surfaces. Then, it calculates the force vectors on each interface by using cameras., 06 Jun. 2008, 2008, "1P1, I08(1)"-"1P1-I08(2)"

This elastic device allows an institutional and dexterous robot manipulation based on vision-based tactile-sensing technology. It provides universal manipulation that can tolerate the personal differences in hand sizes and grasping postures of the users.

We consider that detection of the shape variation is possible through measurement of force vector distribution. Shape variation of an object causes spread of uniform force vectors.In order to measure force vector distribution, the robotic hand was instrumented with vision-based tactile sensor developed by us. Using the robot hand, we have examined the method that detects the shape variation using force vector distribution. As it follows from the experimental result, the robotic hand is capable to detect the shape variation of clay. Therefore, proposed approach could allow us to drastically improve the robotic hand manipulation., 06 Jun. 2008, 2008, "1A1, H12(1)"-"1A1-H12(2)"

To achieve this, we proposed the electrotactile and kinesthetic integration. Our electrotactile display presents natural touch sensations of objects. In addition, this display is so small that it does not invade the moving range of fingers. The haptic interface for dexterous manipulation is realized by mounting it on a kinesthetic display that has wide workspace. We constructed the single-fingered prototype system. Then, we evaluated the manipulation efficiency resulting from the electrotactile-kinesthetic integration. From the result, we confirmed the tendency that the integration improves the accuracy of the manipulation., 11 May 2007, 2007, "1A2, A12(1)"-"1A2-A12(2)"

The proposed transmission system can simultaneously transmit kinesthetic, spatially distributed tactile, and thermal information. Users of this transmission system can recognize the shape and temperature of an object as the initial haptic impression, that a user perceives even if he/she does not move his/her fingertip after initially contacting the object. Therefore, we consider that the proposed transmission system may enable a user to perceive some initial haptic impressions and could therefore be utilized to improve the reality of the haptic sense perceived from a remote object., url

We consider that detection of the shape variation is possible through measurement of force vector distribution. Shape variation of an object causes spread of uniform force vectors.In order to measure force vector distribution, the robotic hand was instrumented with vision-based tactile sensor developed by us. Using the robot hand, we have examined the method that detects the shape variation using force vector distribution. As it follows from the experimental result, the robotic hand is capable to detect the shape variation of clay. Therefore, proposed approach could allow us to drastically improve the robotic hand manipulation., url

From the experimental results, it was found that thermal sensation is the main factor in wet perception of fabrics. In addition, it showed that a change in the contact area and the surface characteristics of the material causing adsorption affect the wet perception. These results concerning the wet perception is useful for constructing a system that virtually reproduces the wet perception of fabrics, and expects to make it more efficient the design, evaluation, and sales of fabric products.

Furthermore, our catalyzation methods using sc-CO2 could improve interaction between Pd and carbonyl carbon in nylon 6,6. We have considered the applications of conductive fibers and it was confirmed the possibility of using clothes and device as one unit by using conductive fiber for wiring. Furthermore, we performed prototype evaluation of two types of wearable computers which support human health.

At first, we confirmed that a warm stimulus with a music, which has bright impression, shows relatively strong emotional effect. Then, we obtained some basic results for design an interface to employ in our daily life. Finally, we constructed a wearable interface that presents the warm stimuli on back of our neck and confirmed its emotional effects when we use it with a home-theater system.

  • Grant-in-Aid for JSPS Fellows, 2011, 2012, 11J05919, Principal investigator, 触運動の相互作用性を再現可能な温度計測の実現による触感伝達の研究, 佐藤 克成, Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for JSPS Fellows, Keio University, 1600000, 1600000, 本研究の目的は、触運動の相互作用性を再現可能な温度センサの構築により、リアリティの高い触感の伝達を実現することである。前年度の研究において、示温塗料を用いた光学式温度計測技術を提案し、触感センサを実現した。また、計測された情報を提示可能な触感ディスプレイを構築するために、温度感覚提示手法を提案した。本年度は主に、提案した温度感覚提示手法を応用した触感ディスプレイを構築するために、その特性を評価した。また、温度感覚提示技術の触感伝達以外への応用として、音楽インタフェースを提案した。 従来の温度ディスプレイは、時間応答性の問題から、人が物体に触れた時に生じる急速な温度変化を再現できず、触感のリアリティが低下する。この問題に対し、人の知覚特性を利用し、温刺激と冷刺激を空間的に分割することで、錯覚的に大きな温度変化を急速に提示する手法を提案している。実験から、この手法を用いた場合に知覚される温度変化量が、温刺激と冷刺激の線形和として表現できることを示した。この知見を用いることで、提案する温度感覚提示手法を触感ディスプレイとして応用し、触感伝達システムを構築することが可能となる。 また、提案手法では温度変化を提示する際、消費エネルギーが従来手法の半分程度になることがわかった。消費エネルギーが少なくなることで、ウェアラブルインタフェースなど触感伝達システム以外への応用も期待できる。 その一例として、温度感覚が人にもたらす情動性に着目し、同様に情動性と関わりのある音楽と組み合わせた、メディアインタフェースを提案した。ヘッドホンの内部に温度ディスプレイを搭載し、曲調の変化に合わせて耳元の温度を温めたり冷やしたりすることで、曲の印象を変化させる。実験から、温度刺激を付加することで、また付加の方法により、音楽鑑賞体験の印象が変化することを示した。
