I enjoyed studying about the properties of light and sound in my high school physics class. When I got to university, I took a course called “Light and Sound” in my first year. One third of the course was dedicated to visual and auditory perception, taught by a very engaging professor. So, from first year University, I was hooked.
A strong curiosity about what you are studying. Attention to detail. A tenacious stick-to-it attitude to see projects through to completion. A logical mind is a bonus but not a necessity. What you might solve logically can also be solved by trial and error – that’s where the stick to it attitude is crucial.
I conduct psychophysical experiments on human space perception. How do we perceive the space around us, and our movement through it, via vision, hearing, and our vestibular (balance) sense organs?
Due to the fact that our eyes are separated in our heads, each eye gets a slightly different view of the world. One consequence of this is that objects at different distances from us project images that fall on slightly different positions in the two eyes. These slight differences are called disparities and are the basis of magic eye pictures and many other 3-D displays. My research on stereoscopic vision is concerned with three general questions: (1) How is it that we see a single world from two laterally separated eyes? Under what conditions do we perceive a single stable world and under what conditions do we experience double vision? (2) How might we design the most ergonomic stereoscopic display -- one that reduces fatigue and enhances the robustness and speed of stereoscopic vision? (3) How does the brain recover a rich, unambiguous 3-D representation of the world when binocular disparities are either absent or ambiguous?
Humans are primarily visual animals. Nevertheless, perceiving events in the world usually involves two or more senses. A complete account of perception needs to consider, in addition to how individual senses are processed, how inputs from different senses are combined in perception. Recently, interest has focused on how inputs from different senses, such as vision and audition, are coordinated. I am interested in identifying and evaluating the conditions under which an auditory stimulus affects visual perception in motion displays. In addition, I am investigating how visual, auditory and vestibular signals are combined in our perceptions of our own movements. This has particular implications for pilots and astronauts who often become disoriented when these sources of information conflict with one another or are out of balance.
I’ve been playing drums and gigging for over 25 years. Gigs have ranged from playing for 2 people to 2000 people in pubs, theatres, weddings, parties, and street corners. I’m still keen to play and have branched out to guitar in the last 5 to 10 years.
