Psychometric functions were collected to measure biases and sensitivities in certain classical
illusory configurations, such as the Müller-Lyer. We found that sensitivities (thresholds or …

Under identical viewing conditions, observers made two types of judgement about the
shape of stereoscopically defined surfaces: one required an estimate of viewing distance for …

As we move through the world, our eyes acquire a sequence of images. The information from
this sequence is sufficient to determine the structure of a three-dimensional scene, up to a …

The present study compared the relative effectiveness of differential perspective and
vergence angle manipulations in scaling depth from horizontal disparities. When differential …

Binocular disparity and motion parallax are powerful cues to the relative depth between objects.
However to recover absolute depth, either additional scaling parameters are required to …

Technological innovations have had a profound influence on how we study the sensory
perception in humans and other animals. One example was the introduction of affordable …

Virtual reality (VR) is becoming an increasingly important way to investigate sensory
processing. The converse is also true: in order to build good VR technologies, one needs an …

We present here a method for calibrating an optical see-through head-mounted display (HMD)
using techniques usually applied to camera calibration (photogrammetry). Using a …

The literature on vertical disparity is complicated by the fact that several different definitions
of the term “vertical disparity” are in common use, often without a clear statement about which …

It is often assumed that the brain builds 3D coordinate frames, in retinal coordinates (with
binocular disparity giving the third dimension), head-centred, body-centred and world-centred …
