  • When: 30th April 2012 14:00 - 15:00
  • Where: Phys Theatre C
  • Series: CS Colloquia Series
  • Format: Colloquium


The human visual system is extraordinary powerful, but it is not a perfect seeing device. In this talk I will use the example of binocular vision to explore visual processing. I will describe some of the biology of the binocular visual system, some of the limitations that the biology presents, and I will describe methods used to probe the relative importance of binocular vision, versus other sources of 3-D visual information. These methods allow us to predict where and when binocular vision provides a powerful source of 3-D information, and is therefore useful to inform the design and production of devices across a range of HCI applications.


Julie Harris is interested in visual perception, with particular interests in how binocular vision and eye movements are used for the perception of shape and depth and the control of action in 3-D space. Current projects include how binocular information is used for distance perception, how gaze patterns can be described in simple mathematical terms, and how we perceive motion in three dimensions.
