Abstract Perceived depth position of autostereoscopic stimulus Kazuki HOJI The glassless stereogram which is known as autostereogram is usually presented on opaque papers or displays and not superimposed to real world. If the vergence angle was identical to the object behind the autostereogram which is displayed on transparent media, it may be easier to fuse it and as the vergence angle is the cue to the perception of absolute distance between object and observers, the apparent depth position may be same as the object behind. Thus, this type of transparent autostereogram may be used for a simple image to superimpose the additional objects to the real object at illusory perceived depth position. However, as the property of the apparent position of this type of transparent autostereogram is unknown, it was investigated in this study. The result showed that although the perceived position was close to the object behind the stereogram, the position is nearer than the theoretical point which is deduced from the vergence angle and the nearer the physical position of stereogram, the closer the apparent depth position becomes. key words autostereoscopic stimulus depth position physical distance vergence angle ii
