Active Gaze and Control of Locomotion.

Under current funding from the EPSRC (2001-2004) we have been investigating the visual information used in steering. As part of this work we have developed a preliminary model where active gaze (where you look and when) is a key component in simplifying the available information and making the task of steering at high speed "simple". The aim of this project is to develop the active gaze model beyond its current status and gain a greater understanding of how humans solve problems such as high speed steering with specific patterns of gaze sampling and visual processing. This type of analysis has the potential to feed into models of the skilled user and the design of assistive devices and the themes outlined overlap with research being undertaken by Volvo for in-car fatigue monitoring. The model also has the potential to feed into robotic control systems that seek to mimic the manner in which humans exploit the breadth of visual information available

The role of predictive information during goal-directed action in children

Approximately 5% of the primary school population present with developmental co-ordination disorders (DCD). Previous research by our group has suggested that these children may have problems shifting visual attention in movement contexts. This research examines this as a contributory factor in DCD and in particular explores the extent to which children with DCD can use predictive information regarding imminent events to direct attention. Understanding the development of dynamic attention and where it may be deficient can assist in shaping remedial programmes for this group.
