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
Removing the blinkers: a wider study of the human eye. Peripheral aberrations, wide-field retinal imaging and optical parameters. This project will study peripheral (side vision) optics of the human eye and its role in the limits of visual performance. This will improve ocular measurements and contribute towards improved diagnosis and treatment of ocular diseases and short-sightedness.
Advanced methods for intraocular imaging. The ability to image the retina of the human eye at high resolution is fundamental to improving understanding of ocular physiology, ocular optics and disease diagnosis. This project applies the relatively new application of active optics to vision science. This project will investigate the advantages of using new beam shaping techniques for characterising the optics of the eye, improving retinal imagery and improving fixation stability.

Using visual science to reduce the dangers of night driving. 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 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
Optical defects of the eye and their relationship to visual performance. All of us will need ophthalmic correction (spectacles, contact lenses and/or refractive surgery) at some stage in our lives. This research is important to the whole Australian community as it will lead to improved equipment for measuring optics of the eye and their effects on spatial vision, better techniques for measuring vision, and obtaining a better understanding of the contribution of the optics to human vision.

This research is important to the whole Australian community as it will lead to improved equipment for measuring optics of the eye and their effects on spatial vision, better techniques for measuring vision, and obtaining a better understanding of the contribution of the optics to human vision. It will provide information about how correcting optical defects through customized refractive surgery and how inducing optical defects (eg with progressive addition lenses) affect vision, and will thus guide developments in refractive surgery and spectacle lenses.

Audio-visual Information for Speech-hand Gestures. How does audio-visual information influence human movement and communication? We will investigate whether speech and hand gestures involve shared information about the timing of rhythmic movements. Using dynamical systems theory and brain imaging techniques, we will study rhythms that emerge during simultaneous speaking and finger tapping in both stutterers and non-stutterers, and in left-handers and right-handers. The communicative interaction ....Audio-visual Information for Speech-hand Gestures. How does audio-visual information influence human movement and communication? We will investigate whether speech and hand gestures involve shared information about the timing of rhythmic movements. Using dynamical systems theory and brain imaging techniques, we will study rhythms that emerge during simultaneous speaking and finger tapping in both stutterers and non-stutterers, and in left-handers and right-handers. The communicative interaction of two persons performing speech-hand gestures will be examined. Results will clarify how brain asymmetry affects gestural coordination in stutterers, how stuttering can be treated, and the hypothesis that speech and language evolved from a communication system based on hand gestures.
