Complex Motion Processing in Primate Visual Cortex. As we move through the world, a dynamic visual image is projected onto our retinas. The pattern of movement in the retinal image contains information about three-dimensional structure in the environment and the time of impending collisions. Our visual systems are expert at exploiting this information, enabling us to navigate through complex visual environments at a level far beyond the most sophisticated artificial systems. We plan to investiga ....Complex Motion Processing in Primate Visual Cortex. As we move through the world, a dynamic visual image is projected onto our retinas. The pattern of movement in the retinal image contains information about three-dimensional structure in the environment and the time of impending collisions. Our visual systems are expert at exploiting this information, enabling us to navigate through complex visual environments at a level far beyond the most sophisticated artificial systems. We plan to investigate complex motion processing in the primate brain by recording the responses of neurons in identified regions of the visual cortex of macaque monkeys to a range of behaviourally relevant motion stimuli.Read moreRead less
Functional Assessment of Head-eye Coordination during Driving. 238 people per 100,000 population were hospitalized and 9 people per 100,000 died as a result of road-transport related injury in Australia in 2002. We will address this issue by assessing the head eye coordination strategies for young drivers, for proficient drivers and for aged drivers to determine those behaviors and strategies that are associated with various levels of performance. This insight could be affectively communicated t ....Functional Assessment of Head-eye Coordination during Driving. 238 people per 100,000 population were hospitalized and 9 people per 100,000 died as a result of road-transport related injury in Australia in 2002. We will address this issue by assessing the head eye coordination strategies for young drivers, for proficient drivers and for aged drivers to determine those behaviors and strategies that are associated with various levels of performance. This insight could be affectively communicated to others and would provide the basis for educational material and methods that would improve operator skill, safety, and performance. These individual improvements would provide overall benefits such as improved transport efficiency, reduced accident rates, saved lives and a reduction in related social costs.Read moreRead less
Vision Impairment and Fitness to Drive. Vision is fundamental to driving. Intuitively vision impairments will significantly affect fitness to drive. However the relationship between vision and crash risk is not well understood and current tests are unreliable. This study will describe the way in which specific vision conditions affect driving performance. The study will examine the effects of visual field loss on drivers' ability to monitor information, allocate attention and minimise the effect ....Vision Impairment and Fitness to Drive. Vision is fundamental to driving. Intuitively vision impairments will significantly affect fitness to drive. However the relationship between vision and crash risk is not well understood and current tests are unreliable. This study will describe the way in which specific vision conditions affect driving performance. The study will examine the effects of visual field loss on drivers' ability to monitor information, allocate attention and minimise the effect of distractions. Outcomes of the study will enable the development of evidence-based guidelines for assessment of vision for driving and effective countermeasures to enhance mobility and reduce crash risk.Read moreRead less
Driving in the Fog: Speed Illusions Caused by Variations of Object Contrast. Accurate judgement of the speed of 3D motion is essential to many real world tasks, from driving a vehicle to playing sports. Illusions of perceived speed can occur when the range of brightness levels (ie. the contrast) is reduced, such as in fog, when suffering from cataracts, or when using some sunglasses. This raises issues of safety for drivers (pilots/captains etc). It is expected that advances in the understanding ....Driving in the Fog: Speed Illusions Caused by Variations of Object Contrast. Accurate judgement of the speed of 3D motion is essential to many real world tasks, from driving a vehicle to playing sports. Illusions of perceived speed can occur when the range of brightness levels (ie. the contrast) is reduced, such as in fog, when suffering from cataracts, or when using some sunglasses. This raises issues of safety for drivers (pilots/captains etc). It is expected that advances in the understanding of these effects will inform road safety policy and practice to benefit drivers and pedestrians and to guide the manufacturing of eyewear and display devices (eg. military heads-up-displays). It is also anticipated that this project will be able to answer the much-debated question 'What colour should cricket balls be?'

Every time we pull up to a traffic light or overtake another vehicle our brain is making a whole series of critical decisions about when and how to carry out the manoeuvre accurately and safely. This project seeks to better understand the processes involved. Using the latest, high fidelity GPS and accelerometer technology, highly accurate measurements of driver behaviour and vehicle dynamics will be made in a real vehicle. Understanding when and how we carry out these types of basic tasks will play a central role in future brake, suspension and steering system design; will help guide the specifications of road and road sign design; and will help motivate additions or alterations to current driver training programmes.Read moreRead less

Pedestrian and cyclist fatalities are a major road safety problem, accounting for a third of road fatalities at an estimated cost of $2.5 billion/year. Late recognition of pedestrians and cyclist by drivers is the main reason for these collisions. We have shown that innovative visibility designs which involve strategic placement of reflective markers on the moveable joints can greatly enhance visibility and hence safety of these vulnerable road users. We will extend this research to incorporate evaluation of these visibility solutions in real-world environments and encourage the widespread use of these designs in the real-world through education and policy change.Read moreRead less
