 note = {As the first step of non-linear modeling of pilot control characteristics by means of the sampled-data control theory, it is needed to delineate human operator's input sampling characteristics in continuous manual control tasks.  This research was conducted to measure the visual information intake frequency (input sampling frequency) of the human operator.  As the experimental result, a clear distinction in the opepator's performance was noted between the above and the below the forced input sampling frequency of 4-5 Hz. From this finding, it was estimated that the frequency of human operator's input sampling lies in the range of 4-5 Hz., 資料番号: NALTM0255000, レポート番号: NAL TM-255},
