[vslist] Postdoc, Research Assistant positions at York University, Toronto

[Rob Allison]

TWO POSITIONS AT THE CENTRE FOR VISION RESEARCH, YORK UNIVERSITY, TORONTO=
, CANADA

Two positions are available in the laboratory of Dr. Rob Allison at the Y=
ork University Centre for Vision Research. We are seeking enthusiastic co=
llaborators to participate in an interdisciplinary programme of research =
in the psychophysical study of human vision.=20

Facilities of the lab include advanced graphics generators, stereoscopes,=
 shutter glasses with fast phosphor monitors, search coil and video eye m=
ovement monitors, motion tracking devices and technology for presentation=
 of advanced virtual environments. Areas of interest for the laboratory i=
nclude depth perception especially stereopsis, eye movements, perception =
of self-motion, and applications to telepresence and virtual reality.=20

The York Centre for Vision Research is an interdisciplinary centre spanni=
ng the laboratories of 23 faculty members in the Departments of Psycholog=
y, Computer Science, Biology and Philosophy (see www.cvr.yorku.ca ). Memb=
ers pursue fundamental and applied research in visual, vestibular and aud=
itory perception, eye-movements, computer vision, virtual reality and rob=
otics.=20

Applicants for these positions should send their c.v., selected reprints =
and the names of 3 referees to:=20

1. Post-doctoral fellowship in depth perception

The project is funded by the Premier=92s Research Excellence program. The=
 initial appointment is for a period of one year with possible renewal fo=
r an additional year. The salary is consistent with current MRC/NSERC sta=
ndards and will be adjusted according to the candidate=92s level of exper=
ience. =20

The candidate should have a PhD in the visual sciences and background in =
visual psychophysics, experimental psychology or computational modeling o=
f human vision. The post-doctoral fellow will design, conduct and analyse=
 experiments that aim to identify basic perceptual mechanisms for perceiv=
ing the three-dimensional layout of the environment. The candidate should=
 have excellent quantitative and analytical skills and experience conduct=
ing behavioural experiments.=20
The project will study will study mechanisms of depth cue combination. Ef=
forts in computer vision and the modeling of neural processing have demon=
strated how difficult it can be to reconcile and =91fuse=92 varied and of=
ten conflicting sensory information. We will focus on cue integration in =
depth perception particularly under conditions of surface transparency an=
d occlusion. A secondary goal for the project will be to explore these is=
sues in a state of the art head-mounted augmented reality display. In man=
y augmented reality or heads-up display applications, monocular images ar=
e superimposed upon stereoscopic images, which may differ in portrayed sl=
ant or curvature. We plan to explore under what conditions the disparate =
surface captures and combines with the superimposed texture and under wha=
t circumstances transparency occurs. The successful applicant will be enc=
ouraged to pursue their own research goals and to interact with the other=
 members of the Centre for Vision Research.


2. Research assistant/associate=20

A pre- or post-doctoral research associate is sought to study perceptual =
human factors issues in simulation and virtual environments. The initial =
contract will be for a period of one year with possibility of renewal. Sa=
lary will be commensurate with experience. The candidate should have expe=
rience in the design of immersive of virtual environments or in applied e=
xperimental psychology. The successful candidate will join a team of comp=
uter and behavioural scientists in an interdisciplinary effort to study h=
uman visual perception in advanced virtual environments.=20
