Abstract:
A micro mirror array plate (MMAP) can present images in mid-air, and several studies using it have been reported [Kim et al. 2014] [Matsuura and Koizumi 2018].We have also developed a method to observe and interact with a 3DCG object in mid-air using MMAP [Takazaki et al. 2018]. In our former method it is possible to observe a stereoscopic 3DCG object in mid-air and interact with it by hand directly. However, the mid-air image using theMMAPhas a problem that the hand always occludes the image regardless of the positional relationship between the hand and the mid-air image.
In this study, we aim to resolve the conflict of occlusion that may occur in direct hand interaction with a mid-air 3DCG object using a MMAP. We propose a method to project an image on a hand when a mid-air stereoscopic 3DCG object should occlude the hand by analyzing the positional relationship between the 3DCG object, the hand and the user’s viewpoint (Figure 1).
