Discussion Meeting “Vision for Movement”.

May 2015. Discussion Meeting “Vision for Movement”.

The aim of this workshop was to bring together people working on humans, non-human animals and robots who are studying visual guidance for spatial tasks from aimed locomotion and path control to navigation and spatial knowledge. The goal was to bring together a collection of PIs with talks that would be pitched at an accessible level, such that we would all be able to learn about the cutting edge and hot topics in cognate disciplines. The attendees were from biology, psychology, neuroscience and engineering departments and certainly had different outlooks on vision, however, three themes emerged. The first was the consideration for the task dependency of vision. i.e. that different tasks have different requirements. Therefore we should not expect to find general purpose neural circuits, cognitive processes or successful engineering solutions underpinning visually guided behaviour. The second theme concerned dynamics and the idea that vision and action go hand in hand through the world. Of course, both these themes reflect the philosophy of Gibson, who featured predominantly in the intro slides of many of our presenters. The third theme concerned the degree of visual processing required for different tasks. This was highlighted most clearly in talks about robotics, where performance, rather than biological plausibility, are key. We learned that in robot navigation a major dichotomy exists between two classes of approach: where vision is used either in an unprocessed or a semantic way. Looking at the biological evidence for navigation (insect, human and rodent) and eye movements, we see that this distinction is still a major discussion point. Overall, the discussion meeting was a great success in bringing people together, highlighting the similarities across disciplines and blurring boundaries between animal and computational research.
