Classifying errors in the use of electronic manuals on a tablet and considering interface improvements

A case study of a collaborative robot assembly manual for non-experts

Abstract

In order to reduce the cost of assembling collaborative robots, we aim to realize a system in which users of collaborative robots can assemble them themselves by referring to an electronic manual on a tablet. To realize this system, it is necessary to provide an interface for the electronic manual that does not interfere with the work. We conducted several experiments in which non-experts assembled a collaborative robot using an electronic manual and remote support from experts. For example, there were errors where non-experts inadvertently skipped reading the electronic manual when they had to repeat similar work. In this research, we summarize these errors and problems with the interface, and describe our plan for improving the interface.
