This video takes an insight into how we process multiple information sources, such as alarms and bridge sensors and how perception is affected by other factors such as night conditions, fatigue and movement.
In fact, CHIRP released a book as well, called "Perception, Decision Making and Fatigue at Sea", addressing this issue. The book provides recommendations for seafarers and operators, explaining how the eyes work with the brain.
According to the book, there are limitations that can affect someone's vision, which are the following:
- Size and distance
- What and where
The “what and where” is very important as it provides information about detail and colour. In order for the “where” system to work better, dim light is necessary, using peripheral vision and it adapts more easily to moving objects. However, “what and where” require different brain activity. This means that they can't both peak simultaneously.
