The pressure exerted by the index finger tip was continuously recorded while the human subject was trying to maintain the pressure at the level of a given pressure (this pressure is named 'target pressure', 0.5〜500g) with optical information for ten minutes, and the results obtained under various conditions were analysed. 1) The errors tended to be minimal in the range between 40 and 50g target pressure, and increased approximately in proportion to the target pressure above 50g. 2) When the subject relaxed his index finger, the errors decreased with decreasing target pressure in the range of less than 50g. 3) The errors were increased by excluding optical information. In target pressure less than 50g, the increment of the errors due to a decrease in the skin pressure intensity was further increased by exclusion of optical information. 4) In small target pressures, the errors tended to decrease transiently in evening, while in large target pressures the errors showed a gradual indrease from morning toward evening. 5) The errors showed generally minimal values 2 or 3 minutes after the beginning of the measurement, and thereafter increased more remarkably in large target pressures than small ones.
