  • The purpose of this study were to compare light touch, two-point discrimination, position sense, and static balance ability and to examine the relationship of static balance ability and different senses in those who are wearing various heights of high-heeled shoes. Each 29 women was classified two different heights (below 3 cm, above 7 cm) by experience in wearing shoes. A t-test was used to determine the differences between low- and high-heeled shoe in light touch, two-point discrimination, position sense, and static balance ability. Pearson correlation was used to examine the relationship of static balance ability to these sensation. The results were as follows: 1) No significant differences in average light touch, position sense between two groups were found(p>0.05). But significant differences in average two-point discrimination, static balance ability were found(p<0.05). 2) Static balance ability was not significantly correlated with light touch, position sense, two-point discrimination(p>0.05). The results suggest that long time experience in wearing high-heeled shoe may be caused local sensory change and decreased static balance ability. Even though, static balance ability was not significantly affected but correlated with two-point discrimination, position sense, and light touch in order.

  • This paper presents an Electrotactile Display System (ETCS). One of the most important human sensory systems for human computer interaction is the sense of touch, which can be displayed to human through tactile output devices. To realize the sense of touch, electrotactile display produces controlled, localized touch sensation on the skin by passing small electric current. In electrotactile stimulation, the mechanoreceptors in the skin may be stimulated individually in order to display the sense of vibration, touch, itch, tingle, pressure etc. on the finger, palm, arm or any suitable location of the body by using appropriate electrodes and waveforms. We developed an ETCS and investigated effectiveness of the proposed system in terms of the perception of roughness of a surface by stimulating the palmar side of hand with different waveforms and the perception of direction and location information through forearm. Positive and negative pulse trains were tested with different current intensities and electrode switching times on the forearm or finger of the user with an electrode-embedded armband in order to investigate how subjects recognize displayed patterns and directions of stimulation.

  • Because of various stresses with rapid change of social structure, the number of the disabled increase steadily. So, the interest of touch garden which the disabled interact with nature and communicate with the non-disabled is more in demand. This study carried out a survey for landuse, facilities, therapeutic garden in creating touch gardens targeting the disabled using them. The results are as follows: At first, the appropriate natural facilities can lead return visit of the disabled. The second, general facilities for information and barrier-free are insufficient. The third, the disabled demand more places for sense of touch and vision, and, also they demand more places for feeling various living things and sense of the season. And the last, the disabled have no experience in therapeutic gardens, but they have consensus for creating special places for the disabled. This study carried out a survey for specially designated user such as the disabled, but through it, it is expected to establish developed design guidelines for creating touch gardens and therapeutic gardens.

  • In this paper, we use VR technologies including touch processing technologies and haptic devices to offer touch of fish objects to users. The Omni, a kind of haptic device and made by Sensable Inc., is used to implement multi touch model in VR space. In addition, Matlab/Simulink and proSENSE Virtual Touch Toolbox of Handshake Inc., are used as programing tools. Functions needed to describe the movement of x, y, and z axis respectively are applied to delineate the natural movement of fish objects modeled with 3D. Such movements offer realistic physical interactions to two users controlling multi point respectively. In experiment, to perceive the appearance of 3D object by touch and to feel the respiration by touch are well conducted. We also verify that it is possible to develop games or contents through multi participation in VR Space by using multi point.

  • This study was designed to measure taste sensitivity and the five basic senses by an educational classification instrument. The instrument was a rice kit that could use samples in a dry powder form or oil extract after long-term storage To test for taste, sucrose, salt, citric acid, and quinine sulfate were made at different concentrations and taste sensitivity was measured on a scale from level 1 to level 5. To obtain baseline data, an inspection tool for the five senses was used and randomly applied on 101 schoolchildren in the third and fourth grade in the city of Cheonan in Korea. The inspection tool was composed of 17 questions; 5 questions regarding visual characteristics and three questions each for characteristics regarding taste, hearing, smell, and touch. The average age of the schoolchildren was 9.5 years old and there were 49 third grade students (9 years of age), and 52 fourth grade students (ten years of age). There were slightly more male students than female students, 56 (55.4%) compared to 45 (44.6%), respectively. The average height of female students was higher than that of males, but the average BMI (body mass index) of the male students was slightly higher than that of female students (18.28 compared to 18.09, respectively). Female students were slightly more sensitive to salty tastes than male students (2.8 compared to 2.5, respectively). In the score distribution for each sense, touch sense was the highest at 7.59, sight sense was 7.49, hearing sense was 5.43, smell sense was 5.24, and taste sense was lowest at 3.69. Therefore, schoolchildren first tend to recognize and deem important the touch and sight of food before its taste.

  • The 1960s is a decade that is marked by new concepts of art making and art appreciation. Starting from Fluxus, the new art in the 1960s such as Happenings and performance art pursued the process of art making as an integral part of artistic experience. The traditional concept of art works that only appeal to vision soon became a site of contentious experiments and innovations in which the experience of seeing is accompanied by other sensual encounters of sound, smell, touch, and taste. These attempts can be seen as a revolutionary move to restore the sense of corporeality to the act of seeing that has been disembodied by the way in which western art has built the unifying, homeogenous field of vision. This paper delves into the works of Fluxus artists - Daniel Spoerri, Ben Vautier, Alison Knowles, Ay-O, and Takako Saito - who were central figures in taking art into the new age of post-ocularcentrism. Exploring the sense of smell, touch, and taste, these artists led the viewer to participate in their art making with the incorporated vision.

  • In recent years, the use of touch screens has expanded, and devices such as remote controllers have been developed in various ways to control and access contents at long range. The wireless-based touch screen is used in classroom, seminar room, and remote video conversation in addition to the TV remote control. The purpose of the study is to design a smart phone-based intuitive interface that can perform the role of a wireless mouse and a wireless keyboard at range using Bluetooth and to develop an application that integrates functions of a mouse and a keyboard. Firstly, touch interaction model for controlling software such as PowerPoint by connecting to a general PC on a smart phone has been studied. The most simple touch operation interface is used to reproduce the function of existing devices and design more simply. The studies of the extension of interfaces with various functions are important, but development of optimized interfaces for users will become more important in the future. In this sense, this study is valuable.

  • In order to be able to interact with the user to experience it as if it were real in virtual reality contents, input/output devices that make them feel the five senses of humans are required . In virtual reality (VR), devices that stimulate sight and hearing are the most representative. For a more realistic experience, suits and gloves that stimulate the sense of touch have recently been released, but there are not many cases applied to actual contents due to the limitation of device . In this paper, we analyze a virtual reality glove that can detect hand movement and touch in a virtual world. Based on the analysis, we propose an algorithm that can sense the intensity of collision with a VR object by tactile sense by improving the UI/UX using the vibration of the feedback method used in the existing virtual reality glove. In addition, the system implemented by the algorithm is applied to an actual case.

  • This Paper presents some of challenges of creating feedback force, through manipulation of master manipulator, allowing the user to feel objects within a virtual environment. A sense of touch for the virtual environment. A sense of touch for the virtual environments was generated by a virtual compliance control method. In theis system data communication between the master and slave, we used TCP protocol. In the experiments. A position error between the master and slave arm was about $13.56^{\circ}$ in case that the master and slave arm had not compliance properties of the virtual object, while they have the its properties the position error reduced by $2.43^{\circ}$.
