Augmented Reality (AR) is expected to be applied to manuals for assembling or inspecting tasks
instead of traditional paper-based ones. Our previous study revealed that when an AR manual was
experimentally used for a wiring task, efficiency became higher and human error decreased.
However, in order to practically apply AR manuals in actual work situations, some human factor
requirements should be clarified in advance. Thus, in this study, we attempt to make it clear what
kinds of effects they have on performance by some conditions or restrictions. Particularly
considering that a user wears a head-mounted display (HMD) and sees images presented by that
superimposed on the real view, we examine the effects of those through some experiments. From
the results, we found that a monocular HMD is better to be worn on nondominant eye, that
information of an AR manual should be given part by part or one by one when the real view is
complicated, and so on. We suggest conditions that do not affect their performance, or rather that
enhance it in actual work situations, in this study.
