JOURNAL FREE ACCESSResearch on a train collision was conducted to gather valuable information to minimize the risk of injury to passengers in the accident, and to explain the following features.
94 percent of collisions at railway crossings occur when a train hits the side of a car. 92 percent of them between trains do when a moving train runs into a stationary train.
A questionnaire, distributed to train accident victims, shows that they were injured mainly by bumping against hand rails, floor, other passengers or windows. The interaction between passengers during the train-impact was especially significant. And one of the effective factors injuring the passengers is how they fall from standing position in a train.
A simulation of the above collision was carried out. The simulation showed, from a point of view of a whole train consist, the necessity of taking a measure to reduce passenger injuries.View full abstractDownload PDF (6450K) -

JOURNAL FREE ACCESSLately many train station in Japan have started to play music indicated a departure of a train (Hence forth it will be referred to as bell music). The objective of our research was to analyze such bell music and its psychological effective. The results of a questionnaire showed that the more a would be passenger is hurrying the more he/she relies upon audio sensory input, in other words what he/she hears. Many expressed a positive liking toward bell music Forthemore, thorough various tests of phrase pattern, it was discovered the bell music should have a slitely faster tempo than regular walking pace, a ascending melody line, and a chord movement going from dominant to tonic. It was also discovered that “correct” tempo differed according to the manner that rythm was kept and also that age made a difference in the way the tempo was felt.View full abstractDownload PDF (1037K) -

JOURNAL FREE ACCESSThis paper presents the results of analysis by using Kansei Enineering as a technique for evaluating the thermal environments. We carried out an experiment to measure the effect of dehumidification under the different room temperature in the climatic chamber. The subjective evaluation based on five factors of thermal sensation were made of a change in humidity and temperature using semantic differential method to examine impressions of static design. The correlations among the subjective evaluation results and humidity and temperature were then analyzed by a multivariate analysis method.
The subjective evaluations of several conditions were plotted on plane with the five factors of thermal sensation. When the temperature is less than 30°C, the dehumidification influenced the subjective evaluation greatly. As the temperature is from 26°C to 30°C, the subjective evaluation about “Comfort” and “Hot/Cold” were changed on a large scale by dehumidifying from 80% to 45%. The result of analysis using quantification method of the first type showed the relationship between the environmental parameters and the words that used semantic differential method for evaluating the thermal environment.
This study suggests that there are correlations between the subjective evaluation results and some environmental parameters.View full abstractDownload PDF (1055K) -

JOURNAL FREE ACCESSThe lifiting motion is often used in the mouse cursor positioning in its retrograde process, whereas it is not used in the tasks by the other pointing devices. This fact seems to cause difference among individual mouse users in the pointing tasks. We present a user model of the pointing tasks with lifting motions. The user model includes 5 parameters corresponding to the human characteristics of visual and motor functions, and their values are obtained by measuring the motion of a mouse for each user. We propose the three types of individual user models, and discuss the application of the models to the optimization problem of movement ratio.View full abstractDownload PDF (5610K) -

JOURNAL FREE ACCESSIn this study, the simple manipulative task of “pick and place” has been performed with instructions available through a computer. The method of measuring the amount of memorized information throughout the learning process can be applied to analyze the effect of kinds of parts, the number of assembled parts, and the memorization sequences. From the results of analysis, the following observations were made
(1) The place of part stored memorization method with sequence of “place of part stored-assembling position-part assembled” can be applied to the case of kinds of parts is less than number of assembled parts.
(2) The assembling position memorization method with sequence of “assembling position-part assembled-place of part stored” can be applied to the case of number of assembled parts is greater than or equal to kinds of parts.
The effective memorization method and the memorization sequence can be used to investigate the individual inclination in feasible memorization method and the memorization sequence.View full abstractDownload PDF (10659K) -

JOURNAL FREE ACCESSAs a basic study of alarm design for home electronic appliances, impression of several alarm sound pattern was experimentally studied. Sixteen types of alarm stimuli were developed by changing pause interval and number of repetitions. These stimuli were generated on a personal computer system using approximated sine waves of 2kHz and 4kHz frequencies. Young and elderly male subjects, and young, middle aged and elderly female subjects were employed as the subjects. They were required to evaluate their impression of the stimuli with regard to eight criteria related to feelings of imminence or urgency, each of which could be evaluated on scale of seven grades. The experimental results showed that the longer the pause interval, or the fewer the number of repetitions, the lower the impression of imminence or urgency. No significant difference in impression of urgency was observed between alarms using the 2kHz and 4kHz frequencies. It was generally observed that female subjects showed a greater impression of urgency than male, and that elderly subjects showed a lower impression of urgency than younger subjects towards the same alarm pattern.View full abstractDownload PDF (5166K)
