| Abstract(in English) | Photometric consistency in Mixed Reality is generally regarded as an important issue. However, it is not well investigated about what kind of photometric inconsistency can make the observers feel a sense of discomfort in the Mixed Reality space. We focus on shadows in MR, and implement quantitative examinations about the position and the size of light source for virtual objects. We also conduct on an experimental investigation about photometric consistency of real/virtual shadows by changing the resolution of the light source map generated from a fisheye image of the lighting environment. According to the results, lower resolution map can display shadows which are perceived as perceptually correct. |
