JOURNAL FREE ACCESSSome experiments on self-paced manual preview control were performed to investigate human characteristics concerning the tracking speed, the error and properties of the eye-movement at such control tasks. We obtain the following basic results.
The increase of the lengths and the complexities of the input preview signals seems to effect on the tracking speed rather than the error. They stimulate the acceleration of the speed, the decrease of the tracking accuracy and the forward movement of the distribution of the eye-fixations. The average smoothing time of the eye-movement does not so change in each situation.
Morerover, we can see that the average speed and the tracking error have a quantitative relation which is proper to the given input signal. In view of information theoretical study on this relation, we have a conclusion that the signal processing time-lag of the human controler seems to be in proportion to the minimum channelcapacity which is necessary to realize the input-output distortion (tracking error) generated by him.View full abstractDownload PDF (958K) -

JOURNAL FREE ACCESSThe purpose of this study was to investigate the usefulness of a simulational approach to the analysis of systematic behaviors in train operation.
The computer simulation was based on the fact that the human operative actions in normal conditions consisting of sequential control behaviors.
The simulation gave quantitative measures for the compatibility of train operation (coefficient of control stability, sensitivity, etc.). Some possibilities of applying the results of the simulation to evaluating the motorman's cab design were suggested.
The method was applied to electric railcar (Series 101) trains of the Yamanote Loop Line in Tokyo and it was suggested that the method would be applicable not only to improving the cab design but also to evaluating the effects of operative environment including location of railway signals and other track conditions.View full abstractDownload PDF (610K) -

JOURNAL FREE ACCESSA series of experiments on sensory measurement (paired comparison) of roughness of turned surface was carried out. The purpose of the present investigation is to clarify individual differences on the measurement and to assess three models: Kruskal's nonmetric multidimensional scaling, Factor analysis and Carroll-Chang's vector model. The results are: (1) With first model, the structure of sensory measurement of roughness and group differences are derived. (2) With second model, inter-individual homogeneity become clear. (3) With last model, inter-individual heterogeneity become clear. Differences among three models and usefuleess in industrial inspection are discussed. The limitation of these models are also discussed.View full abstractDownload PDF (1022K) -
