Relationship of retinal directionality to human retinal anatomy variations. This project aims to improve measurement of retinal directionality, which is the reduction in brightness when a light beam’s entry into the human eye is shifted from the centre to the edge of the pupil. This influences retinal image quality and can be used to measure changes in shape of the peripheral eye. This project will apply advanced technologies in holography, and heads-up displays to explore how retinal directiona ....Relationship of retinal directionality to human retinal anatomy variations. This project aims to improve measurement of retinal directionality, which is the reduction in brightness when a light beam’s entry into the human eye is shifted from the centre to the edge of the pupil. This influences retinal image quality and can be used to measure changes in shape of the peripheral eye. This project will apply advanced technologies in holography, and heads-up displays to explore how retinal directionality changes during accommodation (focusing). The expected outcome is improved understanding of retinal stretching changes during focusing. The benefit is that the project will lead to advancements in retinal imaging.Read moreRead less

This project aims to develop novel tests of visual function relevant to the modern night driving environment. Night driving is challenging for all drivers and has been linked to poor visibility under low light conditions. This project will characterise the visual challenges of the modern night driving environment, develop visual tests that incorporate the dynamic light levels typical of night-time roads and assess the association of these tests with night driving performance. The outcomes will contribute new knowledge regarding dynamic visual processing and the ageing visual system and will inform vision testing, potential interventions to improve visual function for night driving and reduce the dangers of night driving.Read moreRead less

Summary
The role of outdoor activity in myopia development. It has recently been found that spending more time outdoors may reduce the risk of developing short sightedness. This project will examine the underlying basis of these associations and improve understanding of environmental factors involved in the cause of short sightedness, an eye problem that is a major cause of vision impairment globally.
Sensory impairments and driving: can older drivers cope with distracters? This research adopts a multi-disciplinary approach to investigate the problems of older drivers, and drivers in general. The research will provide a clear understanding of how visual and auditory distracters impact upon the driving behaviour and safety of individuals with vision and hearing impairment and those experiencing age-related declines in cognitive skills. The research is highly significant in terms of improving o ....Sensory impairments and driving: can older drivers cope with distracters? This research adopts a multi-disciplinary approach to investigate the problems of older drivers, and drivers in general. The research will provide a clear understanding of how visual and auditory distracters impact upon the driving behaviour and safety of individuals with vision and hearing impairment and those experiencing age-related declines in cognitive skills. The research is highly significant in terms of improving our understanding of how sensory impairment and age-related changes impact upon driving performance, the impact of an increasingly complex driving and in-vehicle environment and will provide tangible benefits for the road safety of the wider community.Read moreRead less
Improving the visibility and safety of pedestrians, roadworkers and cyclists. Pedestrian and cyclist fatalities cost Australia ~$2 billion/year, accounting for a third of road users killed or seriously injured. Late visual recognition by motorists is the main reason these collisions occur. While visibility aids to improve pedestrian and cyclist conspicuity have been advocated, they have had limited success. We will use innovative driving measurement techniques to advance understanding of pedest ....Improving the visibility and safety of pedestrians, roadworkers and cyclists. Pedestrian and cyclist fatalities cost Australia ~$2 billion/year, accounting for a third of road users killed or seriously injured. Late visual recognition by motorists is the main reason these collisions occur. While visibility aids to improve pedestrian and cyclist conspicuity have been advocated, they have had limited success. We will use innovative driving measurement techniques to advance understanding of pedestrian and cyclist visibility and the effectiveness of different visibility aids for enhancing pedestrians and cyclist recognition. We will develop novel visibility aids to maximise pedestrian and cyclist conspicuity and evidence-based educational programs to improve the safety of vulnerable road users.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
