Visibility and Accuracy in a Monocular Augmented Reality System
Some types of AR display have a large field of view so that the AR image may cover the real world. In a binocular AR presentation, the AR image must prevent observation of the real world. However, it is expected that observers can acquire information more easily in a monocular AR presentation because they can observe the real world without any visual interference by using the eye to which the AR image is not presented. The purpose of this study was to examine the superiority of widespread monocular AR presentation in covering the real world information.
Participants traced around a star-shaped figure on a pen tablet monitor using a stylus pen. While tracing, an AR image, which was a translucent, square and covered the entire star-shaped figure, was presented. We controlled the contrast ratio (CR) between the luminance of the AR image and the background on the pen tablet monitor, and controlled the contrast ratio between the background and the star-shaped frame to control the visibility of the star-shaped frame. Each CR was high, medium, or low. When it was difficult to observe the star-shaped frame, participants could not trace the frame accurately in the binocular condition. On the other hand, the accuracy of the task under the monocular condition was consistently better, which suggested that the monocular presentation enables observers to see the real world without interference. The monocular AR presentation can be useful for visual information devices to assist with manual tasks.
