The ANU is talking about some interesting research showing that our eyes can only keep track of three things at once.
the maximum number of signals that can be perceived can only increase to three: far less than if the limit was due purely to signal-to-noise limitations.
“Clearly, there is another processing limit being imposed by the visual system, most likely an attentional bottleneck. To see more than three different directions of motion, and hence more than three moving objects, you have to selectively attend to them, one by one,” he explained.
Dr Edwards said that the new insight into the ability of the average person to keep track of numerous moving objects has important health and safety implications for a whole range of areas such as road design and planning, operator training for vehicles, aircraft and for large equipment, sports training and other activities that demand a lot of our visual system.
But will anyone pay attention?
