When applying augmented reality (AR) in maintenance and assembly, visual search can be performed more efficiently and with less effort using attention guiding techniques (AGTs). However, the focus of attention caused by AGTs could also lead to a failure to recognise obvious changes in the environment, which is referred to as change blindness. In an experiment, six participants wore HoloLens 2 and performed three conditions in a controlled order: search without the help of AGT (baseline), search with arrow as AGT and search with attention funnel (AF) as AGT. In each condition, the trials varied in terms of search angle. In addition, 40% of the trials contained changes of the surrounding virtual objects that participants were required to detect as a secondary task. Search time and change detection were measured. It was hypothesized that AGTs in general, and especially AF, would draw more attention on the search target. This should lead to a reduction in both search time and change detection. The statistical analysis revealed that at small and medium search angles, AF and arrow resulted in significantly faster search times compared to baseline but showed no differences among themselves. At large search angles, only arrow showed an advantage over baseline. In terms of change detection, arrow showed worse results compared to baseline and AF, while baseline and AF did not differ significantly. Contrary to the hypotheses, arrow and not AF led to a reduction in both search time and change detection. Possible reasons for this will be discussed.
