Abstract
AR devices have the potential to augment the space of exhibitions, provide flexible and diverse interactions between visitors and exhibits, and enhance the viewing experience. To keep the virtual objects from blocking the real exhibits, the virtual objects may appear out of view and cause extra searching efforts for the visitors. Current studies have provided multiple guidance methods to deal with the out-of-view problem, yet they haven’t provided specific advice in the exhibition scenario. This research conducted a within-subject experiment in an exhibition to compare three kinds of guidance methods (i.e., arrow, radar, and spatial sound) with relative positions covering 270° of azimuth and 60° of elevation. In this task, participants searched for a virtual object corresponding to the exhibit and completed a NASA TLX questionnaire after the experiment. The findings are summarized into specific application strategies for AR-assisted exhibitions, e.g., the arrow method is recommended for the upper part of the view (0° ~ 30°) while the radar method is more suitable for the lower half of the view (-30° ~ 0°). This research contributes to HCI design in AR HMD by comparing three kinds of guidance methods while considering the positions of the virtual objects.

Using AR HMD in exhibition: Effects of guidance methods and spatial relative positions
AR devices have the potential to augment the space of exhibitions, provide flexible and diverse interactions between visitors and exhibits, and enhance the viewing experience.
