Video see-through augmented reality stereo microscope with customized interpupillary distance design

We developed the Scope+ system, a video see-through augmented reality (AR) stereo microscope with computer graphics technology for medical and biological purposes (Figure 1d). We found out that it was inconvenient for medical scientists or researchers to look up information in reference books or do other tasks while using microscopes simultaneously. To solve the critical problems, we modify the structure of conventional microscope and implement AR technology for a better user experience. Not only text or video information, but also computer-generated content can be overlaid onto the real macro scene (Figure 2b); therefore users don't need to move away from the eyepieces anymore.
