If there is no pictorial depth cue such as size, the patch, which is a small closed region, may stand out. Incidentally, if two fields of random dots that are identical except for a slight shift in a region are presented in rapid alternation, the region appears as an entity reciprocating above the background (RDK). With these phenomena, a number of studies have attempted to reveal several types of perception such as texture, subjective contour, or motion. While Klymenko et al. (1989) reported that a flickering region appeared as a background when the temporal frequency was high, most studies have not focused on depth perception. This study investigates apparent depth of a patch of dynamic random noise within a static field of random dots. Dynamic random noise involves spatiotemporal changes and stimulates moti...

During the different experiments we investigated the effect of providing haptic sensation on Human’s instable stereopsis depth perception. From the different result and discussions we find that such haptic-stereo coupling improved the instability of stereopsis depth perception. As well clearly
