没入型仮想空間における奥行き知覚誤差の計測と補正

Immersive projection displays like CAVE systems are essential for creating immersive virtual environments (VEs). However, they induce depth perception errors that depend on the direction of view. This prevents the use of immersive VEs in various fields. We created a typical immersive VE and measured the depth perception errors. Using this experimental environment, we focused on the contradiction in depth information between that given by the viewer's congestion and that given by the viewer's focus. Our measurement results clarified the effect of this contradiction and the characteristics of depth perception errors in immersive VEs. We also tested error correction polynomial fitting using correction tables. The correction table calculated using the measured data was effective in correcting depth perception errors.
