Outline:In 2000, a new standard (Japanese Industrial Standard, JIS S 0011) was enacted in Japan. The standard provided the perceptual sizes of tactile dots and bars for use in consumer products. However, the numerical values about these sizes were not determined based on data reliable enough. Therefore, objective and quantitative data for perceptual sizes of tactile dots and bars is required for revising this JIS and for devising other standards. In this study, we focused attention on cellular phones becoming common around the world and evaluated the influence of the height of tactile dots (0.0, 0.1, 0.3, 0.5 and 0.7[mm]) on the operational performance of cellular phone. In this experiment, each 20 sighted younger and older participants, whose hand was covered by a curtain, was asked to operate cellular phones with tactile dot on its key 5 and without tactile dot. Both groups performed better with a tactile dot than without it. However, with a dot height of 0.7mm, participants felt significant pain. We determined that there is an appropriate range of the height of tactile dot that improves the operational performance of cellular phones.

Outline:The feel of Braille and Braille readability vary according to the type of Braille output used. In this study, we have developed a model for measuring the 3D cross-sectional shape and size of Braille characters. We measured the sizes of Braille characters printed by three Braille output devices. These devices were made in three countries, namely, Japan, the United States, and Germany. We have also developed a tangible and 3D enlarged Braille model for understanding the relationship between a Braille output device and the 3D cross-sectional shape of the Braille characters outputted by it. This model was displayed at Braille-Big-Event to commemorate the 200th anniversary of the birth of Louis Braille-the inventor of the Braille coding system. Over 200 visitors at this event could easily identify the difference in the 3D cross-sectional shape of Braille characters outputted by different Braille output devices.

Outline:In this study, we developed a sound tactile interface that makes use of the human sensation of hardness. The interface comprises eight elastic objects having varying degrees of hardness. Each elastic object is shaped like a column. When a teacher or a child presses each elastic object, different funny sounds are produced depending on the hardness of the elastic object. The types of sounds used were "Do Re Mi sounds" and "Animal call sounds." We can switch between sound modes using a wireless remote control. The interface has a major advantage in that both healthy children and handicapped children can play with it together. In this paper, we would like conference participants to experience this interface.

Outline:Recently, Transparent-resinous-ultraviolet-curing-type Braille (TRUCT Braille) signs have been spread. However, it has said that TRUCT Braille reading is affected by the friction between forefingers' slipperiness to TRUCT Braille' readability. In previous study, for the purpose of decreasing this friction and enhancing TRUCT Braille readability, we invented a assistive tool of Braille Reading made by polyester non-woven fabric and found that old people with visual impairment wearing it enhances the reading speed and error rate of TRUCT Braille. However, we had to review its material and discuss the fabrication approach. In this study, we compared several materials with polyester non-woven fabric. As a result, we found that sateen weave fabric is better for assistive tool of Braille Reading because of its softness and slipperiness. And we invented fabrication approach of assistive tool of Braille Reading and made its test production.

Outline:Recently, many tactile guide maps have been installed at various public facilities with the enactment of "Barrier Free New Law". In tactile guide maps, some tactile symbols have been used for indicating some information items. Japanese Standards Association enacted Standardized Method of Displaying Tactile Guide Maps March 2007 (JIS T0922). Tactile symbols shapes are regulated by the JIS. However, other components of tactile symbol (such as edge, size etc) are unregulated because there are no sufficient research achievements regarding tactile symbols. In this study, for the purpose of investigating influence of tactile symbols edge clarity on their tactile symbols, we compared tactile symbols discriminability in two conditions with tactile symbol edge clarities (acute type (cutting method) and gentle type (screen printing method)). We made tactile symbol test pieces with various sizes by the two methods. And twelve older participants and twelve younger participants were asked to discriminate tactile symbol test pieces. From this study, we found the relation between tactile symbols edge clarity and discriminability of tactile symbols. It was also found that tactile symbols edge clarity influence on their discriminability when the size was particularly small.

Outline:To determine the effects of aging on the accuracy of perceived foot position, we conducted following experiment to 10 elderly and 10 young participants. Participants were asked to adjust the position of the target line as close as possible to either most medial or most lateral parts of their foot, while they wore a modified cape that obscured their view of their feet. Once they felt that target line was appropriately placed along the foot, the distance between the line and the foot was measured. No age-related differences were identified when they were asked to place the line along with the most lateral part of their foot. Both age groups tended to place the line 10-20 mm over the foot. However, the elderly displayed smaller errors than young when they were asked to place the line along with the most medial part of their foot. We also discussed the possible reasons that explain these features in the article.

Outline:Tactile dots (dot-shaped tactile symbols) placed on the operation keys of consumer products such as cellular phones contribute to improving accessibility for everyone, including persons with visual impairment. JISC (Japanese Industrial Standards Committee) and ISO (International Organization for Standardization) standardized tactile dots and bars. However, sufficient reliable data on the appropriate sizes and cross-section shapes of tactile dots and bars was not necessarily available. Therefore, more quantitative data for optimal dimensions of tactile dots and bars is required to revise existing standards and devise new standards. In this paper, we evaluated influences of the height (0.1, 0.3, 0.55 and 0.75 mm, without tactile dot) and the tip radius of curvature (0.1, 0.3, 0.5, 0.7 and 0.9 mm) of tactile dots on the operational performance in cellular phones. 16 sighted younger participants, whose hand was covered by a curtain, were asked to operate cellular phones with a tactile dot on its key 5 and without tactile dots. As the result, both too high and low height dots are not effective to improve the operational performance of cellular phones and there is an appropriate range of the height of tactile dots regardless of the tip radius of curvature. Furthermore, participants performed better at a particular height with larger tip radius of curvature.

Outline:Recently, touch-sensitive screens have been used for various devices: smartphones, slate PCs, personal media players, etc. Specifically, tablet terminals with a touch-sensitive screen have spread rapidly in the fields of education, medicine, business, etc. However, it has been pointed that their operability is influenced by the difficulty in sliding a fingertip. This study is aimed at examining the influence of the surface condition of the display on the operability of tablet terminals. We measured the coefficients of kinetic friction between the tip of the forefinger and several screen protection films. Our measurements indicate that the coefficient of kinetic friction of anti-glare (AG) film was about one-third that of hard coat (HC) film. Then, we conducted an experiment using these films to evaluate the relationship between the surface condition of the display and the operability. The results show that the surface condition of the display influences the accuracy and speed of operation.

Outline:Raised striped-pattern has been used as a drawing expression of tactile guide map. We are lacking in quantitative data regarding raised striped-pattern for designing easily understandable tactile map. In this study, we investigated the influence of interstices among the lines on tactile discriminability of raised striped-pattern. Ten younger persons and thirteen older ones were asked to distinguish the surface roughness according to 4 categories by comparing 10 raised striped-patterns of different interstices among the raised lines, which were prepared on the basis of the results of previous study. From this study, we found that 5.0mm interstice was necessary for distinguishing different surface roughness and those older persons were somewhat inferior to younger persons in sensitivity of surface roughness.

Outline:We investigated optimal vibrating conditions for inducing illusory elbow extension movement to develop various practical applications. The experimental factors were the vibration frequency (30, 50, and 70 Hz), vibration amplitude (three phases for each frequency condition), and contact press force (3, 5, 7, 9 N). We subjectively assessed the presence or absence of an illusion, and the vividness on a five-point scale. The results of this study showed that when the vibration amplitude and contact press force became higher than certain values at vibration frequencies of 50 or 70 Hz, the illusion was produced for 80% or more participants, and the vividness of the illusion was increased. Under these stimulation conditions, illusory elbow extension movement can be easily produced; we can develop an interface device that will only provide kinesthetic sensations without the actual motion. Such an interface device can be used for rehabilitation and education fields, and gaming devices.

Outline:The portability of touch-sensitive screen tablets provides high usability under various circumstances, and such tablets are increasingly utilized in the education and other fields. Meanwhile, the design of the graphical user interface (GUI) of such tablets requires careful consideration in order not to lose tablet operability in such diverse situations. In this study, we conduct an experiment to investigate the effect that touch-sensitive screen button size and spacing have on operability, while considering the influence of the angle that the forefinger makes when touching the screen. As a result, we could determine the conditions required for the size and spacing of buttons to allow fast and accurate operation independent of contact angle. Furthermore, we could reveal the relationship between contact angle and area, and investigate the impact of the contact angle when touching smaller buttons.

Outline:Braille is a well-known communication tool for the visually impaired. In recent years, as a result of advances in Braille printing technology, the use of transparent resinous ultraviolet cured type (TRUCT) Braille has spread rapidly. As one of the most popular Braille printing technologies, the screen printing method is applied for printing TRUCT Braille. However, the screen printing method produces TRUCT Braille prints of poor quality. In this study, in order to improve the printing quality, we created a device for printing TRUCT Braille. Additionally, we evaluated TRUCT Braille readability for Braille beginner readers by focusing on horizontal and vertical Braille dot distances using our created device. From this study, we found that it was easy to print TRUCT Braille using our device. Braille beginner readers found it easy to read TRUCT Braille with adequate horizontal and vertical Braille dot distances. These findings support the use of TRUCT Braille for new Braille beginner textbooks, as well as for printing Braille signs in public facilities.

Outline::Tactile dots located on operation keys of consumer products such as cellular phones contribute to improving accessibility for older people and people with visual impairment. The Japanese Standards Association (2000) and the International Organization for Standardization (2011) standardized tactile dots. However, reliable data on the appropriate sizes and the shapes was not necessarily available. The purpose of this study is to evaluate influences of the height (0.1, 0.3, 0.55, and 0.75 mm) and the tip radius of curvature (0.1, 0.3, 0.5, 0.7, and 0.9 mm) of tactile dots on the operational performance of cellular phones in younger and older people. Sighted younger and older participants, whose hand was covered by a curtain, operated cellular phones with a tactile dot on its key 5 and without a tactile dot. As the result, both participants performed better at a particular height with larger tip radius of curvature. Furthermore, older participants operated better at high dots like 0.55-0.75 mm. In contrast, younger participants performed better at 0.3 mm and relatively poorly at 0.1 mm and 0.75 mm. Thus, comparatively high tactile dots are useful for improving the accessibility of products for the older and there is an appropriate height range for the younger.

Outline::Tactile dots and bars serve as tactile landmarks so that people with visual impairment can use same consumer products as those used by sighted people. However, reliable age-related data on the appropriate sizes and the shapes was not necessarily available. The purpose of this study is to evaluate influences of edge radius of curvature of tactile dots and bars on their discriminability in younger and older people to determine the appropriate size of tactile bars (as distinguished from tactile dots). Sighted younger and older participants tactually discriminated the tactile dots and bars presented individually, in random order, by a two-alternative forced-choice task. The results showed that both participants discriminated tactile bars from tactile dots faster and more accurately as the dimensional difference between bar length and width increased, regardless of conditions of edge radius of curvature. Therefore, longer dimensional difference between width and length of tactile bars is an important factor to discriminate tactile bars correctly. On the other hand, tactile dots with a larger edge radius of curvature have higher discriminability than tactile dots with a smaller edge radius of curvature in the case of dots of identical height.

Outline:This paper presents a novel sports training system. We developed a visual real-time feedback system that directly transmits a bird's eye view from a drone camera to a player's eyes. Individual physical ability, experience and intuition is important; however, in team sports such as baseball, football and volleyball, players need to perform spatial cognition such that they immediately understand where they, their teammates and their opponents are on the field as if they could see it from a bird's eye view. The objective is to validate the feasibility of the bird's eye view feedback system. In an experiment, nine participants moved and stood between two experimenters as a cut-off man with or without the system. Using the system produced significantly less error than with no system (p < 0.05). In conclusion, this bird's eye view feedback system can improve human spatial cognition.

However, we are lacking quantitative data regarding raised dot patterns for the design of easily understandable tactile maps. In this study, we investigated the influence of dot distances on discrimination of dot patterns used in tactile guide maps by conducting an experiment to find highly discriminable combinations of dot patterns by comparing pairs of dot patterns. The results showed that combinations of dot patterns with a larger difference in dot distances had higher discriminability. When the differences were the same, the combinations of wider dot distances had lower discriminability. Dot patterns with more than 5.0 mm differences in dot distances were highly discriminable for sighted persons, whereas those with more than 4.0 mm differences were highly discriminable for blind persons.

Outline:The satisfactory vibrating conditions and the perceptual properties of inducing illusory horizontal shoulder flexion were investigated in this study. The experimental factors were the vibration frequencies of 30, 50, 70, 90, 110, and 130 Hz. We subjectively assessed the presence or absence of an illusion and its vividness on a 5-point scale. Simultaneously, the perceptual time it took for an illusion to appear and the maximum illusory angle was measured. It was found that the maximum occurrence rate of the illusion was 98% at a vibration frequency of 70, 90, 110 Hz. The illusory angle was approximately 30°. It took 7s for an illusion to appear. Based on this knowledge, we plan to develop an interface device that will provide kinesthetic sensations only without the actual motion in a future study. This device could potentially be used for tactile feedback technology in the virtual reality space.

Outline:Identification of the hardness of an object in a human hand is different according to the hardness of the object. For example, chiropractors identify stiffness in the muscle by using their thumb, which can press more forcefully than the forefinger. However, it has not been shown experimentally if the characteristics of hardness discriminability are different according to fingers. In this study, to clarify the relation between different fingers pressing elastic objects and the characteristics of hardness discriminability, we investigated the differential threshold of hardness using the forefinger and thumb. Additionally, the influence of press force and press displacement on the characteristics of hardness discriminability was clarified. We used 7 elastic test pieces with different Young's moduli as the presented stimuli. We also used the test pieces with hardness sensation judged as 'hard' in our previous research. We conducted the experiment using the constant stimuli method to calculate differential threshold of hardness as one evaluation index of hardness discriminability when using the forefinger and thumb. The results of this experiment showed that the hardness discriminability of the thumb was better than that of the forefinger. In addition, these results suggested that press displacement but not press force should be used to estimate the hardness discriminability and that the thumb is better than the forefinger to discriminate the displacement. These findings clarify the mechanism underlying hardness discriminability in the human hand.

Outline:Identification of the hardness of an object in a human hand is different according to the hardness of the object. For example, chiropractors identify stiffness in the muscle by using their thumb, which can press more forcefully than the forefinger. However, it has not been shown experimentally if the characteristics of hardness discriminability are different according to fingers. In this study, to clarify the relation between different fingers pressing elastic objects and the characteristics of hardness discriminability, we investigated the differential threshold of hardness using the forefinger and thumb. Additionally, the influence of press force and press displacement on the characteristics of hardness discriminability was clarified. We used 7 elastic test pieces with different Young's moduli as the presented stimuli. We also used the test pieces with hardness sensation judged as 'hard' in our previous research. We conducted the experiment using the constant stimuli method to calculate differential threshold of hardness as one evaluation index of hardness discriminability when using the forefinger and thumb.

Outline:The vibrating conditions necessary for induction of the illusion of the metacarpophalangeal joint of index finger flex movement and the perceptual properties of the illusion itself were investigated in this study. The experimental factors were vibration frequencies of 50, 70, 90, 110, 130, 150, 170 and 190 Hz. Subjects were asked to evaluate the presence or absence of an illusion and its vividness on a 5-point scale. Simultaneously, the perceptual time it took for an illusion to occur from beginning vibration and the maximum illusory angle were measured. It was found that the occurrence rates and the vividness of the illusions were highest at the vibration frequencies of 70, 90, 110, and 130 Hz. The response time was about 5 seconds, and the maximum illusory angle was approximately 40 degrees. These findings could potentially be useful in developing a new interface device using kinesthetic sensation.

Outline:The purpose of this study was to identify the key joint kinematics characteristics during walking that related to Locomotive syndrome (LS) in order to develop some kind of device which can assess the risk of LS from gait on a daily basis. For this purpose, joint kinematics data during walking were obtained from 54 healthy community-dwelling elderly subjects (10 belong to LS). From these data, we calculated time-normalized lower limb joint angles on three planes during one gait cycle. For each time point, we also calculated averages and standard deviations of joint angles within the 5 trials. Principal component analysis (PCA) was conducted using input matrix made from the time–normalized lower limb joint angle kinematics (3 Planes × 3 Joints × 101 poins × 2 parameters). To determine Principal Component Vector (PCV) related to LS, we conducted t-tests on the Principal Component Scores of each PCV related to LS between LS group and non-LS group. To understand joint kinematics related to LS, we reconstructed them from each PCV related to LS. Among these PCVs, PCV 6 affect walking speed from hip and anlke joint angles point of view, and PCV 12 affect walking speed from cadence point of view. These PCVs revealed that LS group walks smaller walking speed than non-LS group. Further, PCV 9 related to ROM during walking on sagittal plane: LS group tended to showe smaller ROM than non-LS group. However, this PCV did not relate to spatiotemporal variables such as walking speed or step length. These findings suggest the possibility to develop some kind of sensor systems to assess LS using thesecharacteristics .

Outline:

Hardness identification is one of the most important tactile senses in humans. People use their hands in various ways to identify the hardness of an object. For example, acupuncturists identify stiffness in a muscle by pressing down with their forefinger held flat over the affected area. However, experimental evidence for the role of the pressing method in the identification of an object's hardness even when the same finger is used has not been shown yet. In this fundamental study, we investigated the differential threshold of hardness for different finger postures of pressing (pressing down with one's forefinger held "flat" or "vertically") to determine the relationship between the different finger postures of pressing and hardness identification. We used seven elastic test pieces, each with a different Young's modulus, as the presented stimuli. We conducted an experiment using the constant method to calculate the differential threshold of hardness as a measure of hardness identification. The results showed that the differential threshold of hardness was higher when pressing down with a forefinger held "flat" than when pressing down "vertically" with the same force. This finding will be useful in evaluating the tactile identification of hardness in acupuncturists.

Outline:© 2015 IEEE.Touch-sensitive screen terminals enabling intuitive operation are used as input interfaces in a wide range of fields. Tablet terminals are one of the most common devices with a touch-sensitive screen. They have a feature of good portability, enabling use under various conditions. On the other hand, they require a GUI designed to prevent decrease of usability under various conditions. For example, the angle of fingertip contact with the display changes according to finger posture during operation and how the case is held. When a human fingertip makes contact with an object, the contact area between the fingertip and contact object increases or decreases as the contact angle changes. A touch-sensitive screen detects positions using the change in capacitance of the area touched by the fingertip; hence, differences in contact area between the touch-sensitive screen and fingertip resulting from different forefinger angles during operation could possibly affect operability. However, this effect has never been studied. We therefore conducted an experiment to investigate the relationship between size/spacing and operability, while taking the effect of fingertip contact angle into account. As a result, we have been able to specify the button size and spacing conditions that enable accurate and fast operation regardless of the forefinger contact angle.

Outline:Japanese Industry Standards (JIS) S 0021 (Packaging - Accessible Design - General Requirements) indicate the design policy for easy-to-use packaging and containers, targeting various individuals including elderly persons and individuals with disabilities. The JIS S 0021 includes tactile signs that are necessary to ensure the ease of distinguishing and handling as well as the ease of using those packaging and containers. The JIS S 0021 prescribes tactile signs on shampoo containers and notches for beverage paper packaging containers as tactile signs to distinguish the contents of the package and to differentiate between containers with the same or similar shapes. The policy was expanded to include tactile signs for body soaps when the standard was amended in 2014, and this was attributed to the fact that organizations of visually impaired demanded tactile signs for body soap, since body soap is often packaged in containers with shapes similar to those for shampoos and hair conditioners. Hence, tactile signs prescribed for body soap in JIS S 0021 guidelines were recently expanded to commercially available body soap containers. In the present study, experiments were performed to study the shapes of tactile signs for distinguishable body soap container. Specifically, shapes were studied through the following two steps: 1) tactile signs were selected based on experiments to evaluate the ease of distinguishing between multiple tactile signs, in a hearing survey involving visually impaired; and 2) experiments were performed to evaluate the tactile signs assuming that they were manufactured in collaboration with the Japan Cosmetic Industry Association, which is an industry organization of manufacturers for body soap and other products. It should be noted that the experiments involving distinguishing between products prioritized tactile signs on the top surfaces of the containers instead of on the side, since visually impaired tend to distinguish between pump containers by touching the top surfaces of the containers in hotels and public restrooms. The results of the experiments were used for tactile signs in the amended JIS S 0021 in 2014 for body soap. This study described evaluation experiments performed on the distinguishability of tactile signs on the top surfaces of pump type body soap containers to determine the factors that should be considered when establishing JIS tactile signs for body soap containers.
