How human vision separately determines object and scene motion. This project aims to enhance understanding of how people process visual scenes containing multiple moving objects of interest. The project intends to measure human visual performance to determine how the brain processes multiple motion signals simultaneously. Expected outcomes include an increased understanding of how we are able to use an evolving visual scene to distinguish between changes due to self-motion and those due to the m ....How human vision separately determines object and scene motion. This project aims to enhance understanding of how people process visual scenes containing multiple moving objects of interest. The project intends to measure human visual performance to determine how the brain processes multiple motion signals simultaneously. Expected outcomes include an increased understanding of how we are able to use an evolving visual scene to distinguish between changes due to self-motion and those due to the motion of multiple moving objects such as crowded city footpaths and busy roads. The results will improve our understanding of failures to see moving objects in challenging viewing conditions (for example, high density traffic), and inform work in the design of autonomous driving and augmented reality display systems.Read moreRead less
Peripheral and central mechanisms of sensory coding and integration. The research described in this proposal seeks to provide generic answers to fundamental questions about sensory processes, the nature of perceptual experience, and how these are subserved by the nervous system. The study of inter-sensory interactions in perception has the potential to be incorporated into the development of virtual reality-type computer-based technologies. The neurophysiology research will provide basic informa ....Peripheral and central mechanisms of sensory coding and integration.

The study of inter-sensory interactions in perception has the potential to be incorporated into the development of virtual reality-type computer-based technologies. The neurophysiology research will provide basic information that has the potential to deepen our understanding, and even enhance possible treatment, of neurological conditions that involve sensory systems.Read moreRead less
How do bees orchestrate smooth landings? The results should pave the way for the development of novel, biologically inspired strategies for the control of landing in unmanned aerial vehicles. Endowing aircraft with the capability of autonomous flight and landing has been a major challenge in engineering technology.

Moving between day and night: Navigational strategies and foraging costs of temporal niche partitioning. This study involves fundamental research to identify the navigational strategies and the foraging cost in animals that occupy different temporal niches. It will make use of the unique research opportunities in Australia, by working with endemic fauna that allows scientists to address questions that would otherwise be hard to answer. The project will introduce the novel technique of differenti ....Moving between day and night: Navigational strategies and foraging costs of temporal niche partitioning. This study involves fundamental research to identify the navigational strategies and the foraging cost in animals that occupy different temporal niches. It will make use of the unique research opportunities in Australia, by working with endemic fauna that allows scientists to address questions that would otherwise be hard to answer. The project will introduce the novel technique of differential GPS to track the paths of ants which has the potential to revolutionise the field of insect navigation. Salience-dependent navigational strategies analysed in this study will be of great interest in the field of engineering and robotics.Read moreRead less
Moving to be seen: a comprehensive analysis of movement-based signal design. Papers on visual motion processing and animal signal design regularly feature in major journals, and the programs of international conferences. We can thus be confident that theoretical advances will attract international attention. We will develop further state-of-the-art methods in motion analysis, with our overall approach likely to serve as a framework for future research programs, although our techniques will have ....Moving to be seen: a comprehensive analysis of movement-based signal design. Papers on visual motion processing and animal signal design regularly feature in major journals, and the programs of international conferences. We can thus be confident that theoretical advances will attract international attention. We will develop further state-of-the-art methods in motion analysis, with our overall approach likely to serve as a framework for future research programs, although our techniques will have applications outside of biology. In addition, we will learn much about the social behaviour of a group of native reptiles about which relatively little is known. Research on the social behaviour of animals is readily comprehended by non-specialists and plays an important role in attracting young people to careers in science.Read moreRead less

These benefits range from areas like road safety to clinical neuropsychology.Read moreRead less
Perceiving and tracking moving objects. Processing and tracking moving objects poses challenges for human perception. To succeed, visual processing must accumulate analyses of the object from its different positions. Perceptual experiments will reveal human limits and yield insights into the underlying mechanisms, providing a basis for understanding object tracking in tasks like driving.
Form and motion interactions in human motion perception. Vision works efficiently to detect the motion of both ourselves and other objects by combining motion and pattern information. This project will determine how the visual system achieves this and also create a detailed model that will be directly applicable to areas ranging from clinical neuropsychology to the analysis and design of visual displays.

Just add noise: the benefits of neural and stimulus noise for perception. This project aims to improve visual perception by maximising the beneficial effects of neural and stimulus noise, i.e. stochastic resonance (SR). SR challenges conventional thinking that noise decreases performance. We expect to reveal the underlying mechanisms using experimental and computational approaches.

This project aims to improve visual perception by maximising the beneficial effects of neural and stimulus noise, i.e. stochastic resonance (SR). SR challenges conventional thinking that noise decreases performance. We expect to reveal the underlying mechanisms using experimental and computational approaches. This project is expected to generate unprecedented insights into how noise influences brain processing, leading to a possible re-evaluation of the function of noise in the brain. Expected outcomes include protocols to optimise human performance through SR, and an augmented reality set-up to apply SR to real-world settings. Economic and social benefits include the ability to individually optimise performance in visual tasks using noise.Read moreRead less
