Depth cues for augmented reality stakeout

ABSTRACT

We present the results of a study that compares a range of depth cues for an augmented reality (AR) stakeout application. AR stakeout is the process of placing a real pole on a virtual marker on the ground. Such an application is for example relevant for construction work or surveying. In AR stakeout, interaction takes place at a distance of about 2m from the eye; a distance that has been neglected by AR depth perception research. We compared the performance of six different AR depth cue conditions at two different accuracy requirements. Subjective preferences were strongly in favour of "cast circle", a depth cue introduced in this paper, while there was no significant difference in performance between the conditions. An analysis of the movement patterns indicated that the participants' targeting strategy relied on kinesthetic rather than visual feedback. These movement patterns provide a vantage point for future strategies of targeting support.
