Use of Random Dot Pattern for Achieving X Ray Vision with Stereoscopic Augmented Reality Displays
This paper presents a possible solution to some of the challenges involved with creating a stereoscopic augmented reality 'X ray vision' display, which enables presentation of computer generated (virtual) objects as if they lie behind a real object surface, while maintaining the ability to effectively perceive any information that might be present on that surface. The method involves overlaying random dot patterns onto a real object surface prior to rendering a virtual object. Results from preliminary experiments have shown that the use of random dot patterns can be effective in contributing to the percept of transparency for the case of flat real surfaces with subtle textures. This suggests that the addition of such patterns may also help in perceiving the correct depth order of virtual objects in such images. Moreover, experimental results indicate that, by controlling the relative dot size and dot density of the patterns, it should be possible also to retain sufficient information about the real surface. Future research should be aimed towards the feasibility and effectiveness of applying this method to more realistic AR conditions.
