Professor Brian Rogers

Emeritus Fellow and Dean of Degrees at Pembroke College; Emeritus Professor of Experimental Psychology

I started my academic career as an undergraduate student in Physics and Mathematics but, within a year, I became enticed by the much newer and exciting subject of Psychology.  After graduating, I completed a doctoral dissertation on visual perception at Bristol University before moving to St Andrews and my first academic position as a Lecturer and subsequently as a Reader in Psychology.  In 1984, I moved to Oxford and was appointed to a Lectureship and Fellowship, where I have been ever since.  

As an experimental psychologist, my research interests are in all aspects of human visual perception but specifically in the perception of the 3-D world.  There are many sources of information about the 3-D world but two of the most important are binocular stereopsis (using two eyes) and motion parallax (as a consequence of our movements).  Our research has shown that human observers are able to use both the small differences or disparities between the images reaching the two eyes and the patterns of relative motion generated as we move around to identify and discriminate the fine details of object structure and layout.

I am also interested in the long-standing philosophical debate between those who see perception as a process of inference and guessing based on sparse information and those who believe that the available information about the world is rich and only needs to be “picked up”.  My own view is that perception is better understood as an evolved process that allows us to extract the affordances (meanings) of the world rather than a process for identifying images and objects.

Discovering how humans and other animals perceive the world has important implications for the design and construction of machine vision systems, robotics and the development of display technologies for 3-D TV and cinema.  To this end, we have an active collaboration with the Department of Engineering Science in Oxford as well as with many other universities around the world.
