JOURNAL FREE ACCESSComfortable working area for knob and lever controls was developed to modify the concept of conventional working area. A proposed working area based on the actual working comfort of an operator avoids dichotomy which is the reachability of control devices, and shows a distinct shape compared with existing normal working area following the Farley's concept. It is shown that the distance from the body to control devices and the slope of a work table have the quadratic effect to working comfort, and that the most comfortable area for the controls is located at the distance of about 2-4cm in the sagittal direction and about 42-43cm in the frontal direction from the shoulder respectively, which is located outside the existing normal working areas. The result of the response surface analysis indicates that a little slope of the control panel, about 15°, improves the working comfort. From the study, it was found that the working comfort varies within the working area even if each position is equally far from the body. It is suggested that the conventional normal working area needs to be refined based on the actual working comfort. Moreover, the comfortable working area could differ from control to control, and the primary working area souhld be determined by the type of a control. It is expected that the isocomfort working area generated in this study is used as a useful guideline for control panel layout.View full abstractDownload PDF (2606K) -

JOURNAL FREE ACCESSUnder the rapid industrialization in Asia, participatory approaches have been used as a practical means of ergonomic improvements in small enterprises. Recent experiences confirm that participatory training and research activities can lead to concrete results including ergonomic workplace improvements in different socio-cultural conditions. These participatory activities have been known to be successful when they focus on (1) learning from local good examples, (2) group work methods for identifying feasible solution by the local people and (3) developing practical intervention tools. It is concluded that participatory ergonomic approaches have a large potential for changing workplaces in terms of the safety, health and well-being of workers in small enterprises.View full abstractDownload PDF (503K) -

JOURNAL FREE ACCESSThis paper investigates the job-related low back pains (LBP) in Kuro industrial complex where the manufacturing industries are prevailing. The accident compensation claims during 1992 to 1994 were reviewed and total of 726 LBP related claims were analyzed among 7970 compensation claims. A LBP database was constructed to analyze the back injury profiles of this area. The most frequent cause of LBPs was the manual materials handling related lifting, lowering, carrying, pushing or pulling (45.9%) and the second-most frequent cause was fall and slip (29.8%) and collision (7.9%) was the following cause of LBPs.View full abstractDownload PDF (1500K) -

JOURNAL FREE ACCESSUser's sensibility has an important effect upon appreciating household electronic appliances, and user's feeling of satisfaction with products has a good effect on the choice of product on purchasing those items. In this point of view, the human-oriented approach of product development system can be adopted as Human Sensibility Ergonomics. The target of changed development system is to define user's sensibility factors and to apply them to design and development. In this study, the human sensibility ergonomics approach and usability test have been applied to the development of an electronic product model.View full abstractDownload PDF (533K) -

JOURNAL FREE ACCESSIn this study the relations between foot circumference, width and length changes were experimentally checked using chiefly the method of measurements with projected contours. 162 young men, 396 young women and 42 aged women participated in the experiments. The results showed that the forepart shape of the foot is a very important factor in the determination of the comfort feeling when shoes are on. Thus, when deciding the overall size of a shoe which best fits a given individual, it appears that the foot girth is a more decisive variable to take in account that the general width itself. In particular, differences in foot shapes in individuals, between standard type and wide type, are most remarkable in the foot anterior part, especially, as far as the foot girth is concerned.View full abstractDownload PDF (521K) -

JOURNAL FREE ACCESSThe working posture in a 0G environment is quite different from that in a 1G environment. However, the human engineering data cannot always be collected in a 0G environment. Therefore, data for manned space systems is often collected in a 1G environment. In these cases, subjects may have their muscles strained from maintaining the 0G posture. If so, the data is invalidated. This report studied the validity of collecting human engineering data in a 1G environment for the manned space systems. In this experiment, subjects assumed the 0G posture in a 1G environment to compare with their performance with subjects in a 1G posture. These subjects demonstrated better performance with the 0G posture than the subjects in the 1G posture. From this result, it is concluded that collecting human engineering data in a 1G environment for manned space systems is valid.View full abstractDownload PDF (2887K) -

JOURNAL FREE ACCESSAlthough evaluation of control/display mapping layout has been discussed for a long time, there have been very few methods that enable the quantitative evaluation of those layouts. In this paper, a new method is proposed to calculate the quantitative index that enables the evaluation of multiple control/display layout. The method is based on the idea of complexity of control/display mapping. The index is calculated from the vectors from controls to associated displays. A series of experiments is carried out to validate the efficiency of the index. Using five-by-five control/display models on computer display, subjects are asked to respond to the randomly selected display as quickly as possible by selecting correct control. Six different patterns are used that have different values of the proposed complexity index. The result shows that the proposed index can partially explain the response time, learning speed, and number of errors. The method is also applied to the previous studies that discuss on four-by-four layout patterns. The proposed complexity index is also able to explain the response times and error rates in the results of those studies.View full abstractDownload PDF (865K) -

JOURNAL FREE ACCESSIn previous studies, it has been considered that the pitch frequency included in vocal cord characteristics, the duration and the amplitude contribute to emotion which is conveyed to listeners. But it is reported that the hearing test of synthetic voice which is generated by changing these parameters is conducted and that, as the results, emotion of “joy” could not be sufficiently expressed. Accordingly, vocal tract characteristics in “joy” and that in “surprise” were derived to investigate parameters which contribute the judgement of emotion of “joy”. As the result, the first and the second formants in “joy” were larger than those in “surprise” and the third formant in “joy” was smaller than that in “surprise”. Synthetic voice was, then, generated by changing these parameters, and hearing experiment was conducted. As the result, it was found that these parameters were used in judgement of emotion of “joy”.View full abstractDownload PDF (887K) -

JOURNAL FREE ACCESSThe purpose of this study is to examine the measurement methods of the electromyogram (EMG) and the event related potential (ERP) in order to evaluate the fabric hand while a subject touches a fabric voluntarily. Subjects were asked to touch some types of fabrics repeatedly during some of 10s. EMG and ERP were measured before and after the moment when the subject touched the fabric. The result showed that the variations of EMG patterns in voluntary touch of a fabric were related to physical features of a fabric. Some subjects showed the ERP components related to active touch.View full abstractDownload PDF (7231K) -
