Reducing fire deaths - a new approach to smoke alarms. Disturbingly, those most at risk of dying in residential fires are also least likely to awaken to the current smoke alarm signal, now mandatory in Australian residences. This project will develop a new alarm (using Gibsonian, naturalistic sounds and/or a voice signal) and compare its waking efficacy with the current smoke alarm. Testing will involve three vulnerable groups; sleep deprived young adults, children and alcohol intoxicated. The r ....Reducing fire deaths - a new approach to smoke alarms. Disturbingly, those most at risk of dying in residential fires are also least likely to awaken to the current smoke alarm signal, now mandatory in Australian residences. This project will develop a new alarm (using Gibsonian, naturalistic sounds and/or a voice signal) and compare its waking efficacy with the current smoke alarm. Testing will involve three vulnerable groups; sleep deprived young adults, children and alcohol intoxicated. The research is innovative with important implications for community public safety, the national and international smoke alarm industry, performance based models of building safety and our theoretical understanding of cognitive processing during sleep.Read moreRead less
Waking up to a fire - optimising the smoke alarm signal. On any one night a significant proportion of the population is at risk of sleeping through the current smoke alarm in a fire emergency. Significant risk factors for not awakening include being a child, sleep deprivation, being a heavy sleeper, use of sleeping tablets, alcohol intoxication, and being aged over 60. Yet research suggests that a different alarm signal will awaken these groups more effectively at a lower volume. This innovati ....Waking up to a fire - optimising the smoke alarm signal.

Using innovative occlusion and training research designs on a driving The proposed project examines the contribution of a mental model approach to the perception of time and speed of own and other vehicles using innovative occlusion and training research designs on a driving simulator. Participants will be asked to make time and speed estimations under varying environmetal conditions such as urban and rural scenes, straight and curved roads, and with and without engine noise, and under drug states. The generality of the findings will be tested on an instrumented car. The project will increase our understanding of factors influencing speed perception, a critical component of safe driving behaviour.Read moreRead less
Experimental and computational assessment of the mechanical, musculo-skeletal and neuromuscular contributions to rhythmic multi-joint arm movements. The human body is a complex mechanical system that is controlled by a vast neural network comprising many millions of connections. To date, realistic descriptions of the interactions between these neuro-mechanical features have proved elusive.

The human body is a complex mechanical system that is controlled by a vast neural network comprising many millions of connections. To date, realistic descriptions of the interactions between these neuro-mechanical features have proved elusive. This project seeks to develop a mathematical model that accurately describes the essential features of the control system for human movement, and yet is simple enough to inform the design of artificial devices to generate or assist movement. The knowledge derived should improve mechanical and neural prosthetic systems, and guide rehabilitation protocols. The work will ultimately provide a considerable benefit to the community by reducing the social cost of a range of movement disorders.Read moreRead less
An inverse control approach to resolving the neural basis of spatial and muscular dependencies in coordinated multi-limb movements. Each year 48,000 Australians suffer from stroke with many survivors left with problems that limit limb function. With reduced duration of hospital care, the opportunities for retraining in the period immediate following stroke are rapidly diminishing. Effective and efficient strategies of rehabilitation that will maximise the level of recovery following stroke will ....An inverse control approach to resolving the neural basis of spatial and muscular dependencies in coordinated multi-limb movements. Each year 48,000 Australians suffer from stroke with many survivors left with problems that limit limb function. With reduced duration of hospital care, the opportunities for retraining in the period immediate following stroke are rapidly diminishing. Effective and efficient strategies of rehabilitation that will maximise the level of recovery following stroke will result in benefits expressed in terms of enhanced quality of life and functional life-span, as well as significantly reduced costs of health care. In understanding the fundamental principles underlying the stability and adaptability of movement coordination, this research is likely to make a significant contribution to the design of programs for movement rehabilitation.Read moreRead less

Spatio-Temporal Precision of Interceptive Action. Interceptive actions like hitting a moving target require precise, accurate positioning and timing. This project aims to empirically document how spatial and temporal constraints affect performance of interceptions and to quantify the speed-accuracy trade-off for interceptions. The speed-accuracy trade-off for movements aimed at stationary targets has been extensively documented - slower movements are more accurate.

This project aims to empirically document how spatial and temporal constraints affect performance of interceptions and to quantify the speed-accuracy trade-off for interceptions. The speed-accuracy trade-off for movements aimed at stationary targets has been extensively documented - slower movements are more accurate. There has been no corresponding documentation for interception. This project will fill the gap and provide a rich data set for developing an understanding of interception through modeling work. An understanding of the factors governing interception has potential applications in road safety, sports and neurological rehabilitation.Read moreRead less
