Summary:The objectives of this paper are to investigate the effects of auditory feedback and tactile feedback on usability of touch panel and to find out the improving mechanism of touch panel usability. Four kinds of stimulus conditions are prepared with the absence or presence of auditory feedback and vibration feedback. In experiments, subjects are given phone number task under the stimulus conditions. In order to evaluate the usability, task duration is measured by using timer counter function in the touch panels, and eye-fixation duration is measured with an eye tracking system. From the experimental results of 24 subjects, it was found that not only the task duration but also the fixation duration on the touch panel are influenced by the stimulus conditions. Accordingly, the reason why the task duration under the condition with auditory feedback or vibration feedback becomes shorter seems to depend on the fixation duration on the touch panel. Since it is well known that auditory reaction time and tactile reaction time are faster than visual reaction time, it was guessed that subjects could more quickly judge the completion of phone number input by using auditory and tactile senses.

Summary:わが国では自動車の安全性能向上により交通事故の件数が減少しているが、高齢人口の増加に伴い、高齢者の事故件数は増加している。高齢者が事故を起こす原因として加齢による認知機能・身体機能の低下がある。著者らはこれまで転倒予防靴下の開発を行ってきた。そして、足関節の背屈を支持し、母趾の外反を抑制する機構を備えた靴下を履くことで、足関節の背屈角度と母趾の伸展角度が増加し、下垂足の軽減に効果がみられ、転倒予防に役立つことが示唆された。他方、今川らは下垂足患者に対し、内反・尖足対策用の軟性短下肢装具を用いた場合の歩容改善について報告している。今回、高齢者が事故を起こす原因の一つである身体機能の低下、すなわち疲労に着目し、足関節と母趾の形状を矯正する靴下を用いて運転時の疲労軽減に関する基礎実験を行った。健常高齢者9名を対象とし、まず普段着用している靴下と従来の軟性短下肢装具(背屈位を支持する装具)を用いた「ペダル踏みかえ実験」、次に今回試作した靴下(内反小趾対策靴下)を用いた同実験を行った。結果、従来の軟性短下肢装具よりも内反小趾対策靴下のほうが精神的負担を感じにくいうえ、姿勢安定性に寄与する可能性が示唆された。

Summary:【目的】交通環境では排気ガスをはじめとする悪臭物質が自動車室内へと流れ込んでいる．そこで本研究では自動車の空調システムにおいて異臭原因物質の主成分であるプロピオン酸，吉草酸，酪酸に着目し，各物質がマウスの自発運動能におよぼす影響を調べた．また，定量的な評価をおこなうため，各物質の投与方法は腹腔内への注射による投与とした．【方法】本研究には18週齢のC57BL雄性マウス24匹を用いた．全てのマウスに対し，自発運動能測定システム（Wheel Manager, MED Associates Inc.）を用いて回し車（直径10.9cm）の回転数を60分間測定し，controlデータとした．次に24匹のマウスを，注射の有無による影響を調べるためのリンゲル液投与群，悪臭物質による影響を調べるためのプロピオン酸（1µg/kg）投与群，吉草酸（1µg/kg）投与群，酪酸（0.5µg/kg）投与群の4群各6匹ずつに分けた．なお，4群のcontrolデータにおいて一元配置の分散分析をおこなった結果，各群の間に統計学的な有意差はなかった（P>0.05）．各物質をそれぞれの群のマウスの腹腔内に投与し，controlデータと同様に自発運動能を60分間測定した．各物質の投与による統計学的有意差の検定にはウィルコクソンの符号順位和検定を用いた．【結果および考察】リンゲル液を投与した群では投与の有無による統計学的な有意差はなかった（P>0.05）ため，注射による腹腔内投与の影響はないと判断した．プロピオン酸，吉草酸，酪酸を投与した群では，controlデータと比較して回転数が減少した．とくに酪酸を投与した群においては，統計学的な有意差があった（P<0.05）．本研究を通して，悪臭物質がマウスの自発運動能に影響をおよぼすことがわかった．以上のことから，ヒトにおいても悪臭物質は快／不快の感覚に影響を与えるだけではなく，運動能に影響を与える可能性が示唆された．

Summary:The purpose of this research is to investigate the load of back muscles in driving the wheelchairs. Two types of wheelchairs were used in this research. One of them was a usual self-propelled wheelchair, other one was a new type with lever devices. These studies were performed on 10 healthy young subjects, who had normal neurological history. Electromyography (EMG) recording was carried out in 8 muscles (trapezius, upper and lower portion of deltoid, latissimus dorsi, triceps brachii, common digital extensor, brachioradialis, flexor digitorum profundus) during driving the wheelchairs. As a result, the EMG data indicated that the load of back muscles was lower during driving the new type of wheelchair than usual one. Additionally, these studies were performed on 4 spinal cord injury victims. However the results of them did not indicate similar trends to healthy subjects.

Summary:In the field of research for the intelligent transportation system (ITS) and the roving robot, the driver-support system auto-recognizing road sings and the robot control system auto-recognizing behavior-indication signs are variously suggested. Both systems use the dynamic image processing to acquire features such as the shape and design of sings. Artificial sings valid for the machine vision are sometimes used for these researches. However, this study uses general road sings adopted in public roads, because machines such as robots and vehicles are supposed to be live together in real environments. In this paper, nine kinds of one third of sings for size such as "Stop," "No entry" and "No passage" are prepared, and then some experiments to recognize these signs are carried out under various kinds of measurement condition.

Summary:For the design and development of vehicles, it becomes more important than ever to offer the comfortable driving environment. This study focused on the air-conditioning system of a car, and the comfortableness for a driver was evaluated using the bioengineering technology. The experiments were carried out by electroencephalogram measurement and electrocardiograph measurement for a driver near the air conditioning outlet inside the passenger car. As a result, the correlation between the comfortableness and the thermal environment was gained: 1. It became clear to be able to evaluate the amenity using electroencephalogram measurement (content rate of α wave) and electrocardiograph measurement (LF/HF value). Though it is said that it is more comfortable when the LF/HF value is lower, and when the content rate of α wave is higher, both measuring results were well corresponded. 2. It was proven that the peak of the amenity for both data appeared at some temperature (temperature of car's interior or near the air-condition outlet) as experimental results. 3. It was also proven that not only the temperature but also the humidity influence the amenity.

Summary:The purpose of this study is to inspect how the vestibular sensation would be influenced by the visual or the auditory stimulation. A rotatory chair, the 16 speakers and the 4 laser pointers were used for stimulators. These stimulators were placed in the dark anechoic room. From the experiment results, it was found that the perception of rotatory motion was clearly influenced by the moving sound sources and the moving lights in some subjects. However, the other subjects were little influenced. We also examined the reason why the difference of the perceptions between two groups was occurred.

Summary:［Abstract］For the disabled and the long-lived, wheelchairs are effective to expand their field of activities. It is well known that wheelchair users are exposed to whole-body vibration when they move around on wheelchairs. Then, this paper discusses the whole-body vibration in driving an electrically powered scooter. We executed experiments to measure three axes of the frequency weighted r.m.s. acceleration on seat surface of an electrically powered scooter at three types of road surface. The experiment results suggest that the user of electrically powered scooter was exposed to considerable amplitude of whole-body vibration. In addition, it is recognized that the future work is to propose countermeasures for improving the discomfort and health effect from whole-body vibration of an electrically powered scooter seat by using 12 axes acceleration measurement based on ISO2631-1.
- Effects of differences in the control switch of air conditioning units on maneuverability, 樹野 淳也, 中村 一美, 米原 牧子, 田中 一基, 竹原 伸, 近畿大学次世代基盤技術研究所報告, 3, 47, 54, 2012 06 , http://ci.nii.ac.jp/naid/120005730407
Summary:[Abstract] Most traffic accidents are caused by inattentive driving. Inattentive driving occurs when drivers operate devices unrelated to driving. This paper evaluates the maneuverability of control switch of the air conditioning unit. We performed an experiment to compare the operation of three kinds of control switches: lever switch, knob rotary switch, and dial rotary switch. The experimental results showed that the subjects could perform the tasks more accurately using the knob rotary switch compared to that using the dial rotary switch and lever switch. The difference in the operation of three different control switches is as follows: In the case of the knob rotary switch and lever switch, the subjects are able to hold the switch at the central position by arm kinesthetic sense, and the motion error gets canceled when the subjects operate the control switch continuously. In contrast, in the case of the dial rotary switch, subjects are not able to recognize the switch rotation without visual confirmation, and the error accumulates whenever the subjects operate the switch. The next stage of this research involves the development of a switch that operates without visual confirmation. In the future, it is expected that the control switch of the air conditioning unit will not only possess a merchantable design but will also produce better results during its operation.
- Effect of surface texture on glossiness and color for wrinkly textured surfaces in automotive interior, 米原 牧子, 樹野 淳也, 中村 一美, 竹原 伸, 近畿大学次世代基盤技術研究所報告, 3, 73, 77, 2012 06 , http://ci.nii.ac.jp/naid/120005730411
Summary:[Abstract] Texture is one of the important factors to characterize appearance of products. However, its quantitative evaluation is difficult and the proper evaluation method has not been developed yet. In order to solve this problem, in the present study, we proposed several parameters applicable for quantitative texture evaluation. Effects of surface roughness on glossiness and surface color were investigated for wrinkly textured surfaces in car interior. With decreasing skewness Rsk, glossiness increased. The lightness L* and color coordinate b* change with the arithmetical mean roughness, Ra. The present experimental results showed that the texture can be evaluated quantitatively by using three combined parameters: surface roughness, glossiness and surface color.

Summary:[Abstract] The touch panel iswidely used in many applications; ATM, FA instrument, car navigation system, cell phone and so on. Although the advantage of the touch panel is that change and update work are easy compared to mechanical switches, the touch panel has a serious problem that it gives no click feeling to operators. Therefore, as a result of researches on touch panel with tactile feedback, some items have been available commercially. However, there are few researches to evaluate the touch panel with tactile feedback. Then we carry out experiments where subjects enter sixteen telephone numbers to touch panel. So, we discuss the affects of differences in sensory feedback on task duration of subject.

Summary:For the design and development of vehicles, it becomes more important than ever to offer the comfortable driving environment. This study focused on the air-conditioning system of a car, and the comfortableness for a driver was evaluated using the bioengineering technology. The experiments were carried out by electroencephalogram measurement and electrocardiograph measurement for a driver near the air conditioning outlet inside the passenger car. As a result, the correlation between the comfortableness and the thermal environment was gained: 1. It became clear to be able to evaluate the amenity using electroencephalogram measurement (content rate of α wave) and electrocardiograph measurement (LF/HF value). Though it is said that it is more comfortable when the LF/HF value is lower, and when the content rate of α wave is higher, both measuring results were well corresponded. 2. It was proven that the peak of the amenity for both data appeared at some temperature (temperature of car's interior or near the air-condition outlet) as experimental results. 3. It was also proven that not only the temperature but also the humidity influence the amenity.

Summary:In the field of research for the intelligent transportation system (ITS) and the roving robot, the driver-support system auto-recognizing road sings and the robot control system auto-recognizing behavior-indication signs are variously suggested. Both systems use the dynamic image processing to acquire features such as the shape and design of sings. Artificial sings valid for the machine vision are sometimes used for these researches. However, this study uses general road sings adopted in public roads, because machines such as robots and vehicles are supposed to be live together in real environments. In this paper, nine kinds of one third of sings for size such as "Stop," "No entry" and "No passage" are prepared, and then some experiments to recognize these signs are carried out under various kinds of measurement condition.

Summary:The purpose of this research is to investigate the load of back muscles in driving the wheelchairs. Two types of wheelchairs were used in this research. One of them was a usual self-propelled wheelchair, other one was a new type with lever devices. These studies were performed on 10 healthy young subjects, who had normal neurological history. Electromyography (EMG) recording was carried out in 8 muscles (trapezius, upper and lower portion of deltoid, latissimus dorsi, triceps brachii, common digital extensor, brachioradialis, flexor digitorum profundus) during driving the wheelchairs. As a result, the EMG data indicated that the load of back muscles was lower during driving the new type of wheelchair than usual one. Additionally, these studies were performed on 4 spinal cord injury victims. However the results of them did not indicate similar trends to healthy subjects.
