Book excerpt: The psychophysical Method of Constant Stimulus Differences was used to determine difference thresholds and Weber ratios for both direct and remote lifting of two standard weight stimuli. A Model 8 Master-Slave Manipulator was used for remote lifting. For 1000-gram weight, difference thresholds were 65.42 and 110.45 grams for direct and remote lifting, respectively. Corresponding difference thresholds for a 3000-gram standard were 149.33 and 195.69 grams. The difference threshold indicates the fineness of weight discrimination which can be expected of a worker. Increases in difference thresholds as a function of remote lifting reflect the loss of feel associated with remote handling. The difference threshold is proposed as a criterion of the fidelity of cues reflected to the operator by the remote-handling system. (Author).

Book excerpt: Mn's abilty to make differential and absolute judgments of remotely handled masses was invesigaed under simulted weightessness condtions. An analysis of the results revealed: () remote handling under weightlessness conditions produes increments in jus-notceable differences which are roughly proportional to the mas of the remote manipulator components involved in handling the stimulus objects; (b) differential sensitivity for mass can be improved by increasing the accelerative force imposed upon the stiulus objecs; (c) absolute jugments tend to be less under weightlessness condiions for either direct or remote handling; and (d) remote handling tends to prodce greater and more variale estimates of both weight and mas.

Available in PDF, EPUB and Kindle. Book excerpt: Man's ability to estimate weights was determined for two lifting conditions: direct manual lifting and remote lifting by means of an Argonne National Laboratory Model 8 Master-Slave Manipulator. The effect of interpolated weight-lifting experience upon absolute judgments of weight was also examined. Results show that: (a) means of estimates made by subjects who lift weights remotely are greater than means of estimates made by subjects who lift the same weights directly; (b) subjects tend to underestimate weights lifted directly; (c) estimates for the remote-lifting condition, even though more accurate on the average, are more variable; and (d) the tendency for subjects to underestimate weights which follow heavier weights and overestimate those which follow lighter weights is more pronounced for direct lifting than for remote lifting.
