Using Virtual Reality to Examine Gait and Postural Sway Changes in Eye Disease

A consequence of eye disease is progressive vision loss that can impact on how visual information is detected and utilised for visually guided behaviour. In this study we will examine the effect of vision loss on judgements of self-motion. We will use virtual and augmented reality to simulate vision loss and postural sway in response to viewing a simulation of a moving world. A pressure board will measure sway and gait in response to increasing simulated vision loss. In addition, these body measurements will be correlated with objective judgements of self-motion speed and direction to see if they can predict changes in self navigational behaviour. This research will tell us not only about the consequences of vision loss, but also its impact on self-motion behaviour.

Lead Academic: Dr Sieu Khuu, School of Optometry and Vision Science

Sieu Khuu

Sieu’s research program is primarily focused in the discipline of visual perception with emphases on cognitive and visual neuroscience. This research seeks to understand the computational rules underlying the extraction and processing of visual information and how this information is used by the visual system to aid visually guided behaviour. This research focuses on the following areas: 1) To contribute to the understanding of visual perception with emphasis on the computational processes that underlies the perception of 3D motion and form. 2) To understand how the visual system detects image contrast, and how efficient and focused measures of this visual function can be applied to vision screening and the diagnosis of visual dysfunction.



Mentor: Jacinta Walz

Jacinta Walz

Jacinta is currently an undergraduate Advanced Science student and research assistant at UNSW studying Vision Science and Mathematics. She is currently researching visual system markers for cognitive deficits in traumatic brain injury and, the impact of environmental factors, such as luminance, on depth perception. She will complete Honours next year (2020) with the School of Optometry and Vision Science at UNSW. It is her aim to study and research different ways to monitor and manage visual impairment and, support those living with low vision.
