Description

The ideal AR x-ray vision should enable users to clearly observe and grasp not only occludees, but also occluders. In this paper, we report a first evidence for the validity of a vergence-based selective rendering both occludee and occluder layers with dynamic opacity in AR x-ray vision. Using the gaze depth as a trigger to select the layers has an essential advantage over using other gestures or voice commands in the sense of avoiding collision between user's intentional selection and unintentional actions. Experiments with a visual paired-comparison task shows that the proposed method has achieved a 20% higher success rate, and reduced 30% of the average task completion time than a non-selective method using a constant and half transparency. The results prove the feasibility of vergence-based AR x-ray vision.
