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.

55‐1: Invited Paper: Superiority of Monocular Augmented Reality when Continuous Viewing is Required

“…This revealed that participants might be able to distribute their attention to the peripheral field of view more efficiently in the monocular condition. In a previous study [15], a wider UFOV in the monocular condition had been demonstrated; however, participants only briefly looked at an AR image. In the present study, we demonstrated that a wider UFOV was observed not only when the observation duration was short, but also when continuous viewing was required.…”

“…We have proposed a monocular AR system to solve this problem [13,14,15]. This is an AR presentation style of images, in which images are presented to one of the user's eyes, not to both of their eyes.…”

“…See following Figure 5. It has been found that if AR is developed for smart glasses the monocular vision should be preferred because it has superiority compared to binocular vision due to comfort [24]. Also, an AR system should be lightweight, comfortable and have a large battery life for outside.…”

“…Other characteristic is monocular vision versus binocular vision of smart glasses. Akihiko Kitamura et al concluded the monocular presentation is superior for real-world tasks than binocular presentation, even when observers need to pay attention to an AR image and the image is less visible in monocular presentation [24]. Also, the parallax problem, binocular displays where both eyes see the same image causes significantly more discomfort than monocular displays, both in eye strain and fatigue [25].…”

A survey of augmented reality: Making technology acceptable in outdoor environments

“…One possibility would be that of using equipped glasses. These glasses need to be suitable for outdoor use, taking into account the weight, size and field of vision, for instance, Akihiko Kitamura et al in their studies about monocular versus binocular vision, conclude that monocular are superior to binocular glasses for real-world tasks, especially when observers need to pay attention to an AR image, because the image is less visible in the monocular presentation [16]. Binocular displays cause significantly more discomfort than monocular displays due to the parallax problem [29].…”
