Comparison between binocular and monocular augmented reality presentation in a tracing task

Abstract

To establish the superiority of monocular presentation in augmented reality (AR) over binocular presentation, we report two experiments involving a tracing task with an AR image covering a visual field observed in both the monocular and binocular conditions. In Experiment 1, the subjective visibility of the AR image and the accuracy of the tracing task were measured. In Experiment 2, participants identified a character in the AR image while tracing. The AR image was less visible in the monocular condition than in the binocular condition. Hence, participants could observe the real world more easily in the monocular condition, and the resulting performance on the tracing task was better in the monocular condition. Information acquisition from the AR image in the monocular condition was equivalent to that in the binocular condition. These results exhibit the superiority of monocular AR presentation for the performance of manual tasks.
