Biography
Associate Professor Cass is a vision scientist, psychophysicist and cognitive scientist. He researches sensory processing and decision making in order to produce systems that improve performance, productivity and ultimately the lives and wellbeing of those who use them.
While there is no shortage of technologies that aim to help us find our way around or make decisions, most fail to take the limitations of our brains into account when they present us with reams of information.
His research aims to find ways of processing sensory information in a way that is most digestible for the human brain.
"The brain is constantly bombarded with vast amounts of sensory information every second. Yet somehow, we perceive that the world makes sense and is highly organised. I am interested in how the brain achieves this."
One stream of his work involves understanding how the human brain is able to make sense of the infinite combination of sensory events it is exposed to in everyday life. This can involve how we combine information within a given sensory system (for example, vision) or between sensory systems (for example, vision and audition).
Another stream of his research uses virtual and augmented reality technologies to create human-machine systems and interfaces that are optimised to the processing constraints of the human brain, including how cognitive load and stress affect our ability to extract multiple sources of information.
