(Summary) Tactile walking surface indicators (TWSIs) are installed on footpath to support independent travel for the blind. There are two types of TWSIs, attention patterns and guiding patterns. The attention pattern is usually installed at the crosswalk entrances. The direction of the crossing can be acquired by the row of the projection of the attention pattern through the soles of the shoes. In addition, truncated domes or cones of the attention pattern were arranged in a square grid, parallel or diagonal at 45 degrees to the principal direction of travel. However, the international standard organization (ISO) allows a wide-ranging size. In this research, the direction indicating performance was compared at the same intervals for the five diameters specified by the international standard. As a result of the experiment, the diagonal array does not indicate the direction of travel, but the projection row does indicate the direction of travel in the parallel array. When the attention pattern is installed at a crosswalk entrance, a parallel array should be installed in the direction of the crossing.

(Summary) Amyotrophic lateral sclerosis (ALS) is a progressive, intractable disease that causes the body to gradually become weaker. A communication device for the handicapped with a high degree of disability (see Fig. 1) is often used for a seriously ill ALS patient. However, the degree of the symptoms differs in each patient, so it is necessary to select a suitable input switch. Moreover, the selection of the switch is greatly influenced by differences in knowledge and experience, so support is often advanced preceded by a subjective evaluation [1]-[6]. This research developed an evaluation apparatus capable of measuring the movement of the finger from the displacement of the lever using a sensor built into the input switch. As a result, appropriate support is expected to evaluate patient's remaining function based on objective data when the input switch is selected.

(Summary) The authors have been continuously researching tactile walking surface indicators and audible pedestrian signals used for crossing intersections. A pedestrian walks to the opposite side of the crosswalk using audible pedestrian signals. The position where the audible pedestrian signal is set up clearly influences the pedestrian's path. We performed an intersection crossing experiment with road noise for different positions where the audible pedestrian signal was set up. Vehicle road noise is thought to influence walking pedestrians. However, we could not clearly separate the difference of where the audible pedestrian signal was set up from the influence of the road noise. We therefore conducted the experiment with no road noise in the intersection to determine the difference of the position where the audible pedestrian signal was set up. The research results were compared with and without road noise to specify the road noise influence.

(Summary) When a person with visual impairment attempts to cross the road without any assistive systems such as audible pedestrian signals, it is hard to judge correctly the direction to cross the road and the timing to start walking. Recently, the assistive guiding and wayfinding system which utilizes the infra-red (IR) technology has been developed and applied to assist the visually impaired persons to cross the intersection in Japan. The same system is used as an audible signage in the United States. When using this system, the user has a hand held IR receiver terminal and moves it horizontally to search the direction of the IR transmitter. When the user finds the direction, he/she starts walking toward that identified direction. This study examines the coordination between the direction of the terminal held by the user and the direction of human sense of the user. The result shows, when moving the hand held terminal with keeping elbows close to his/her sides, the user can find the walking direction more correctly and walk toward the identified direction more precisely. In addition, when using the receiver with 10 degrees of light receiving angle, the user can find the walking direction that is similar to the one identified in the case of using the modern tactile walking surface indicator.

(Summary) In Japan, it is reported about 90% of the persons with visual impairment are the persons with low visual capability. However, the database of the low visual capability and the standard about the easily comprehensible visual information presentation are not existed yet. Therefore, the categories of colour similarity of the persons with low visual capability are measured. However, measuring various colour combinations is placing a burden on the object person. Therefore, in this research, development of the categories of colour similarity estimation algorithm is proposed. Applying the generalization capability of the artificial neural network, the distribution of the categories of colour similarity will be obtained from the limited colour combination measures.

(Summary) Obstacles, especially small differences in floor level and ramp in housing often cause difficulties for manual wheelchair users with regard to access. The degree of difficulty is dependent on body frame, the diameter of the wheelchair's casters, and the user's ability to propel the wheelchair. To estimate the difficulties associated with various types of level differences and ramps quantitatively, the load on user and the ability of the user were studied. Using the date for overcoming the level differences, we attempted to determine quantitative scales for reasonable height and shape of level differences of ramps for manual wheelchair users.

(Summary) An experiment to evaluate a tactile walking surface indicator for visually impaired persons was usually carried out in the outdoor environment, and the weather and the seasons affected on the schedule and the result. We constructed the evaluation system within the building so we could conduct walking experiments that were unaffected by the weather regardless of the four seasons. The subjects of this system were not only a visually impaired person and a sighted deaf person but also general person. The laboratory provided a soundproof and shaded structure consisting of the walls and the ceiling. External sound and light were blocked. The hue could be adjusted by three-color fluorescent lamps, and the light could be adjusted from daytime brightness to a dim moon light. Research into the walking of visually impaired persons at nighttime is a pressing problem as the barrier-free transportation law has been enacted in Japan. An international standard has been discussed, and a scientific basis for that standard is now required.

(Summary) Maneuverability of wheelchair depends not only on mechanical efficiency but also on the environmental condition where the wheelchair runs. So, we have been aiming to comprehend mechanism of influences of road/floor conditions on maneuvering the wheelchairs quantitatively. In this paper some information obtained through many test runs of experimental wheelchair on longitudinal slopes are reported. The load/distance rate that is momentum needed to move l m, is useful to evaluate difficulty in maneuvering the wheelchair quantitatively. Furthermore, knowledge about factor that causes failure in negotiating a longitudinal slope by the wheelchair was acquired. Making use of the knowledge, the indicator that can estimate whether a wheelchair rider will be able to negotiate a longitudinal slope on the basis of measurement of his/her traction force using simple push-pull gauge for example.

(Summary) this paper describes the merits for power consumers brought by the combination use of photovoltaic generation and nighttime power storage using the storage battery. The merit of the combination system is calculated based on the insolation and consumers load pattern. The merit using insolation at the specific region and general load pattern has been already reported. This paper examines the influence due regional and load pattern differences, and studies the changes of the merit and the optimal storage battery capacity. The other hand, it is difficult to measure the actual load pattern of the ordinary residence, so this paper uses the generalized load pattern to comparatively examine the difference in merit and optimal storage battery capacity from those for the actual load pattern.

(Summary) In this paper we examine the merits that a practical photovoltaic system combining photovoltaic generation with storage batteries would provide if it used in ordinary residences. Various configurations and operation methods could be envisaged for such a system. In this research we examined the optimal battery capacity, operation methods, and economic effects for a system emphasizing economical merits for the user. We first calculated the hourly amount of photovoltaic generated electricity each month, and used data on average load patterns from actual measurements to calculate battery capacity. Next, taking battery capacity and phtovoltaic module capacity/price as parameters, we calculated and evaluated the economic merits for ordinary residences. The results showed that the optimal battery capacity for combination with 3 or 5kW photovoltaic generation is around 10kWh, and that a combined system provides merits even though it entails higher photovoltaic module costs than the use of photovoltaic generation alone.

Using the wheelchair, we investigated the influences of floor surface conditions and position of the rear wheels on manuevering it. The result shows that the faster the wheelchair runs, the less momentum per 1 meter traveling when running on soft surface floor, and that shifting the position of rear wheels forward might make the running performance of wheelchair slightly efficient. And, it became clear that the center of gravity of wheelchair-rider would be shifted backward at push phase. That might have an effect on improving running performance of the wheelchair.

(Summary) In order to make a guideline of housing and building design which considered the wheelchair users, it is also neccesary to take into consideration wheelchair user's dynamic components other than spatial components. This study critically investigates whether the mentioned standards in the existing guideline are satisfying all the needs of wheelchair users. We used the methods of quantitative evaluation of driving a manual wheelchair and collected the dynamic data under the different conditions of flooring materials, ramps and levels. The rate of a physical load and capacity on driving a manual wheelchair drawn from this research can be utilizable as a new index of floor design.

(Summary) In this paper we examine the merits that a practical photovoltaic system combining photovoltaic generation with storage batteries would provide if it used in ordinary residences. Various configurations and operation methods could be envisaged for such a system. In this research we examined the optimal battery capacity, operation methods, and economic effects for a system emphasizing economical merits for the user. We first calculated the hourly amount of photovoltaic generated electricity each month, and used data on average load patterns from actual measurements to calculate battery capacity. Next, taking battery capacity and phtovoltaic module capacity/price as parameters, we calculated and evaluated the economic merits for ordinary residences. The results showed that the optimal battery capacity for combination with 3 or 5kW photovoltaic generation is around 10kWh, and that a combined system provides merits even though it entails higher photovoltaic module costs than the use of photovoltaic generation alone.

(Summary) To prevent visually impaired persons from falling from railway platforms, we performed an experimental study to evaluate the effect of widening the tactile ground surface indicators(TGSI) that warn them when they are nearing the platform edge. The focus of the evaluation was the detectability of dot tiles and the stopping distance required after they had been detected. As a result, it was not only proved that the typical width of 300 mm is effective, but also that adding 100 mm improved that effectiveness. The detection rate reached 100 % when the width was 600 mm.

(Summary) There are individual differences in the degree of disorder and appearance of low vision people, but in many cases discrimination of light and darkness is possible. Therefore, it is considered effective to use flashing light as support for low vision people. As support for such low vision, research is being conducted in this laboratory to introduce a light emitting blinking block at the entrance to the pedestrian crossing. In this study, as an introduction study of the development of luminescent block for support to amblyopia, we asked subjects to evaluate the intensity of blinking stimulus when presenting blinking light to subjects and the goodness of visibility by sensory evaluation, Consider the blinking method best suited for support.

(Summary) Of the five human senses, vision is said to account for 80% of the in-formation acquired. The presentation of light is an effective way to convey visual information. A blinking presentation especially attracts attention. A low-vision person acquires peripheral information through residual vision. In this case, light effectively supports the travel of low-vision persons. A blinking light stimulates more than a continuous light. However, a blinking light is not sufficiently compatible with the surrounding environment. This research investigates an environmentally friendly blinking pattern to arouse attention.

(Summary) The gaps and steps between platforms and trains reduce the accessibility and mobility of persons with wheelchair in railway transportations. Using an experimental platform, the observations were performed how gaps and steps influence their capabilities for wheelchair users with spinal cord injuries. A quantity of Normalized Driving Force (NDF) was introduced to evaluate the abilities of getting on/off trains. Dynamic wheelchair driving force was measured by using torque meter equipped on the wheelchair to analyze the power boarding on trains. To improve practical accessibility of persons with wheelchair, an assistive device for boarding trains was designed and verified.

(Summary) Since about 90% of the vision impaired in Japan are said to have low visual capacity (hereafter referred to as ``LVs''), TWSIs visual recognizability has great significance. For color conspicuity, sufficient data on LVs is not yet collected, while the data on people with no vision impairment are ready. In order to study proper TWSIs colors, based on scientific-evidence and independent from conventional wisdom, we created a system to measure the conspicuity focusing exclusively on colors. In conclusion the system's usability to measure color conspicuity for LVs was verified.

(Summary) Information technology makes possible to develop sophisticated assistive systems for persons with visual impairment. Guiding and wayfinding systems utilizing infra- red (IR) technology have been developed in United States and the technology is applied to the intersection in Japan. In order to use the system described above, a person with visual impairment has to have a hand-held terminal or a hands-free terminal with eyeglasses. When the person is going to cross the roads, he/she will find the direction to go utilizing the directivity of the terminal. The points to check whether the walking route to the opposite side of the crosswalk will be good or not are: (1) The relation between the direction of a terminal held by the user and the direction based on his/her sensation is well coordinated or not. (2) How to be trained/learned for coordinating his/her body with the information of arm's or head's direction. This paper describes the research on human characteristics of directing and the system coordination between arm or head and foot for utilize IR system.
19.	Osamu Sueda : Systematic Research on Tactile Walking Surface Indicators in Japan, Proceedings of The 12th International Mobility Conference, Vol.C1-3, 1-6, Hong Kong, Nov. 2006. (Summary) The tactile walking surface indicators, TWSIs, were invented by Mr. Seiichi Miyake in Okayama Prefecture, Japan, in 1965. The TWSIs have been used worldwide. In the process of spreading all over the world, many types of TWSIs have been designed in many countries and some of them have been adopted as standards or guidelines in the countries. Internationally, the necessity of standardization grew with the wave-like expansion of worldwide globalization. The Japanese government carried out systematic research on TWSIs. In the experiment, parameters were designed to include not only the patterns that existed at that time but also the patterns that would be designed in the future. From the experiment, the detectability of individual patterns became clear and the discriminability between the attention pattern and the guiding pattern was also clarified. From this data, the optimal dimensions of the two kinds of patterns were determined as JIS T9251. Also the new pattern for the platform edge at railway station was developed in order to notify the blind of the inside/outside of the platform to prevent them from falling down onto the tracks.

(Summary) The riding comfort of manual wheelchairs is greatly influenced by tactile walking surface indicators (TWSIs) that are usually set on sidewalks for visually impaired person. The goal of our research is to understand how block patterns and their vertical vibrations influence the ride of manual wheelchairs. This paper also presents a system that easily measures the vibration characteristic of the walking frame. Using various tactile walking surface indicators as a rugged path, this system measured the vibration when using various walking frames. This paper, therefore, considers the vibration influence of TWSIs on wheelchairs with and without suspension equipped wheels and various walking frames.

(Summary) 近年．機械的な不確かさやパラメータの時変性を有する系に対してセルフチューニング制御やインテリジェント制御などの適応·学習制御が応用され，その有用性が検証されている．本稿では，棒ねじれ系の近似モデルとして扱われている3慣性系速度制御をCMACを用いて行う．CMACはモデリングなどの手間を省くことが可能な上，演算アルゴリズムも簡単であるが，外乱などに対する安定性·ロバスト性能は良いとは言えない．そこで，非線形ロバスト制御器の一つであるスライディングモードコントローラ(以下SMC)を状態フイードバック制御器として適用する．提案手法であるCMACがSMCを補催する制御系がSMCのみによる制御系よりも制御精度が良いことを示し，同時に外乱に対するロバスト性も存在することを数値計算により示す． (Link to Publication Site) ● Publication site (DOI): 10.1109/ICSMC.2004.1401224 (Link to Search Site for Scientific Articles) ● Summary page in Scopus @ Elsevier: 2-s2.0-15744368791 (DOI: 10.1109/ICSMC.2004.1401224, Elsevier: Scopus)

(Summary) 本稿では3慣性系の位置制御に対するトラッキング制御を行うことを目的とする．これまでも様々な制御手法や設計方法が提案されている.しかし，状態フイードバックによる制御を行う場合，モデリングをはじめ，厳密なシステム同定が不可欠になる．そこで本提案手法では，従来のフイードバックコントローラに適応フイードフォワードコントローラ(以下，AFC)を付加したフイードバック誤差学習の形をとる2自由度制御系を構成する.AFCにはニューラルネットワークの一種である小脳演算モデル(以下，CMAC)を用いる．提案手法であるPID制御器とCMACによる目標追従制御とする．これより提案手法であるCMACをAFC(フイードフォワード補償器)として用いた制御系が従来のPID単体による制御や，それにNNを付加した制御系に比べて学習が高速且つ良好な制御特性を示すことを検証する

(Summary) ``Guide/Warning block improvement investigative commission'' of The Ministry of Transportation, MOT, carried out following three researches on the structure for installation of tactile ground/floor surface indicators, TGSI's, on railway platform. 1) The maximum distance between the platform edge and TGSI's was studied. In Japan, TGSI's shall be placed 80cm or over back from platform edge. We performed an experiment with 34 blind persons, asking them whether or not they felt ``astonishment (or danger)'' because the distance was shorter than they had expected. As the result, we determined that the distance shall be maximum 100cm as a rule. 2) The special structure of TGSI's at the edge of platform was designed to notify the direction toward/against for the edge. As the result of study, we determined that one linear protrusion line neighboring at 9cm from the dots on the safe side of the platform shall be installed for direction. 3) The lower limit of the interval between two TGSI arrays was studied to prevent the fall-down from another side of edge at narrow platform with 35 blind persons. As the result, we determined that the ideal interval is 60cm, or at least 40cm or over in case 60cm is not applicable.

(Summary) The gap between the amount of available information that an intellectually handicapped person understands and the amount of available information that a person without such a difficulty understands is becoming increasingly wider. In other words, the environment of information surrounding an intellectually handicapped person is relatively worse than before due to the progress made in information technology. However, this progress in information technology also holds out the promise of improving the information environment of hte intellectually disadvantaged.

27.	Osamu Sueda : Issues in the Now-Familiar Information Society, Osaka Forum -Abstracts-, 59-62, Osaka, Oct. 2002. (Summary) How can we secure accessibility of information in the IT society for poor people, people with disabilities, and elderly people in developing countries? This is the biggest issue in the current global community. In the United States, Section 508 of the Rehabilitation Act has been effectively enforced since June 22nd, 2001, which has greatly affected not only the United States but also Japan. And, the companies concerned and the administrative authorities have united in promoting the measures to deal with the influence. How far will the current development of IT-related equipment and the current computarization of information go ahead, while taking the accessibility for people with disabilities into consideration? I would like to survey the latest IT-related equipment and how the standards have been improved with consideration for peolpe with disabilities and elderly people, in order to think about future problems.

(Summary) When blind or vision-impaired persons travel alone they might encounter problems and hazards in various situations. Tactile walking surface indicators (TWSIs) were invented in Japan in 1965. It is for this reason that TWSIs perceived through use of a long white cane, through the soles of the shoes and through use of residual vision have been developed. They are now used around the world to help blind or vision-impaired persons to travel independently. At present, TWSI patterns and installation methods vary from country to country. This paper outlines the international standard by which these are reflected. Moreover, an international standard of acoustic orientation signals are outlined in this paper, and the installation method is examined.

(Summary) An experiment to evaluate a tactile ground surface indicator for visually impaired persons was conducted in a simulated outdoor environment in which the weather and the four seasons were controlled. We constructed the evaluation system so we could conduct walking experiments that were unaffected by the weather regardless of the four seasons. The subjects of this system were a visually impaired person and a sighted deaf person. The laboratory provided a soundproof and shaded structure consisting of the walls and the ceiling. External sound and light were blocked. The hue could be adjusted by three-color fluorescent lamps, and the light could be adjusted from daytime brightness to a dim evening environment.

(Summary) Crossing an intersection is one of the most risky actions for a person with visually impairment. A visually impaired pedestrian is guided to the crosswalk entrance by the tactile walking surface indicators "TWSIs". TWSIs are necessary for persons with visually impairment to walk independently. Audible pedestrian signals are also necessary for them to cross intersections. TWSIs support approaching the intersection, and audible pedestrian signals support crossing the intersection. However, the support of audible pedestrian signals may not necessarily be related to the support of the TWSIs. This research sought to verify how visually impaired persons are guided by different positions where the audible pedestrian signals are set up.
