複合現実空間におけるShape-COGIllusion知覚の新たな知見

摘要

Mixed reality (MR) is the technology which merges real and virtual worlds in real-time. In MR space, a real object can be changed its visual appearance by superimposing a CG image (CGI) on it. We confirmed that the presence of center-of-gravity (COG) can be changed by MR visual stimulation in our previous work. And we named this illusion the "Shape-COG Illusion". In this paper, we verify effects of superimposing virtual object of a pole on real object of a pole. We measured the perceived COG of180 combinations of real objects and virtual objects. We analyzed relationship between COG of real/virtual objects and perceived COG.%我々はこれまで，実物体に重心の異なる仮想物体を重畳描画すると実際と異なる重心を知覚する現象を発見し，Shape-COG Illusionと名づけた.本論文では，実物体より仮想物体の重心が近い場合，仮想物体の重心が極端に遠い場合に仮想物体·実物体の重心が変化した際の知覚される重心の傾向を調べるため，重心の異なる実物体と仮想物体の組み合わせ計180組に対して，重心位置を回答させる実験を行い，傾向の分析を行った.
