An experiment to evaluate audio-visual instructions about parts position in an assembling task

Effect of Instructions on Parts' Positions during an Assembly Task on Efficiency and Workload

“…However, no differences were found between Condition-B and Condition-A as well as between Condition-B and Condition-N [8], although there should have been differences according to the 2nd hypothesized outcome as the search time had decreased in that case.…”

“…Therefore, we hypothesize that in a complex assembly task in which the workers cannot memorize the assembly processes, positional instructions regarding the location of the parts will enhance the task's efficiency as well as make the work more comfortable for the worker because of reduced mental stress. Previously, we conducted an experiment in which we restricted instructions to visual and/or auditory during an assembly task in which educational blocks were used to investigate the effect of the parts' positions in-structions [8]. However, because some results left room for reconsideration, an additional experiment was conducted.…”
