Direct measurement of sensuous depth imaged by 3-D display observer
H Kuribayashi, M Date, H Takada, S Suyama, T Hatada
The quantitative measuring method of the imaging depth using sensuous distance expression of a human is proposed. With the adjustment method, it is difficult to measure psychically perceived depth of 3-D images, because the observer can compare precisely the physical distances by optical triangulation information when he watches two targets at the same time. In our proposed method, observer presents the perceived depth as distance between forefinger and thumb. The measured depth agreed well with the actual depth, when observer imaged distance between two real objects aligned in depth direction. The effect of monocular depth cues (relative size, contrast, color difference) could be also confirmed. Then we measured the perceived depth when observer saw a 3-D image displayed by a DFD display, in which an apparent 3-D image was produced by only overlapping two 2-D images displayed at different depths. The results showed that DFD display can produce accurate depth as well as real objects. Moreover, the perceived depth tended to be enhanced when monocular depth cues were added synergistically.
