This paper describes studies on perception of virtual object locations. It explores the behavior of some factors related to depth perception, especially the effect of inter-pupillary distance (IPD) mismatch and the interplay of image blur and binocular disparity. IPD mismatch (which is caused by errors in estimation of the parameter) results in a certain perceptual error of virtual objects' depth. Blur of images is also a source of error in depth representation. It was found, in some cases, to be a very strong depth cue. The results of a series of experiments conducted on IPD mismatch and image blur are also presented.
