Training School lectures:
Day 1: Monday 27th June: Basic anatomy & physiology of visual system
1.1 Jenny Read: The eye
Basic anatomy / physiology of the eye. Photoreceptors, retina, pupil, , lens, cornea. Rods, cones, colour perception. Dynamic range, cone adaptation.
1.2 Bruce Cumming: Eye movements
Eye muscles. Saccades, fixation, pursuit, microsaccades. Measuring eye movements. Vergence.
1.3 Bruce Cumming: The visual brain
Basic anatomy /physiology of brain areas involved in vision. Techniques for studying brain, e.g. single-unit recording, multi-electrode arrays, fMRI, PET, EEG – pros & cons. Brain areas involved in perceiving 3D; ventral/dorsal streams: difference between “perceiving” and “acting”.
1.4 Jenny Read: Stereopsis
Disparity, stereopsis. Stereoacuity and stereoblindness. Binocular vision disorders: amblyopia, strabismus. The correspondence problem. Issues with mobile eyes; epipolar lines, search zones. Different forms of human stereopsis: fine/coarse, contour vs RDS. Demos: measure your stereoacuity with different clinical stereotests such as Randot, Titmus, ASTEROID.
Day 2: Tuesday 28th June: Introduction to psychophysics
2.1 Simon Watt: Measuring perception of the 3D world?
Using tape, marker pens, and string to explore different ways to measure the magnitude and precision of perceptual estimates—something that turns out to be surprisingly challenging.
2.2 Ignacio Serrano-Pedraza: Signal detection theory
Dprime; decision criterion; hits, misses, false alarms, correct rejects. ROC curves.
2.3 Jenny Read: The human contrast sensitivity function
Spatial and temporal frequency. Difference between band-pass luminance CSF and low-pass chromatic CSF; applications to encoding of colour. Fourier spectra of images. Models of the CSF.
2.4 Ignacio Serrano-Pedraza: Channels and the human disparity sensitivity function
The human DSF and its poor spatial/temporal resolution compared to contrast. Stereo anisotropy. The idea of channels and the masking/adaptation approach to studying them.
Day 3: Wednesday 29th June: Reconstructing the world in 3D
3.1 Simon Watt: Why the visual system isn’t a measurement device
Perception as inference, Emmert’s law, the ‘problem’ of multiple cues, sensory integration (a.k.a. optimal way of combining different depth cues), combining sensory inout and prior knowledge of the world (Bayes Theorem as a general mechanism).
Slides are available to attendees only.
3.2 Andrew Glennerster: Visual cues to depth
Optic array, sampling the optic array by moving your head around in it, motion parallax cues to depth; optic flow; conceptual similarity between flow/motion parallax and disparity. Visual stability. Task-dependency in vision versus reconstruction.
3.3 Andrew Glennerster: Perceiving depth & distance
Absolute vs relative disparity, metric depth. Size and slant perception. Vertical disparities.
3.4: Simon Watt: Focus cues
Accommodation and retinal blur. Differences between real-world and stereoscopic 3d displays, cause of vergence-accommodation (V-A) conflict, effects of V-A conflict, tolerance to V-A conflict.
Slides are available to attendees only.
Day 4: Thursday 30th June: Current and future 3D displays
4.1 1 Ignacio Serrano Pedraza: Adaptive psychophysical procedures
Bayesian staircase procedures, threshold and slope estimation.
4.2 Andrew Glennerster: Head-mounted displays and immersive virtual reality.
‘Reconstructing’ the D world around us (or not). Navigating, pointing. “Fictional stable world” as an example of cue combination. ‘Correct stereo for all head positions’ versus stereo as a sub-sample of possible views.
4.3 Simon Watt: Focus cues in S3D
Specific and general solutions, compensation for small disparities, eye-gaze-dependent approaches, volumetric displays, fixed-viewpoint volumetric displays (a.k.a. multi-focal-plane displays), evaluation studies of these.
Slides are available to attendees only.
4.4 Gordon Love: Replicating accommodation cues with technology
Multi-plane, birefringent, lightfield displays.
Slides are available to attendees only.
Day 5: Friday 1st July: Applications of 3D technology
5.1 Nicolas Holliman: Visit to The Core to see 3D Decision Theatre
5.2 Naeem Soomro: S3D displays for laparoscopic surgery
5.3 Panel discussion: What would the ideal 3D display system look like?
