Both internal and external factors are contributing to the complexity of the driving environment. Traffic conditions, sophisticated car management systems, ubiquitous communication devices, and so on demand increased levels of visual and cognitive attention from drivers. Despite this, modern in-car information displays increasingly more and more information. As a result, the displays are cluttered and distracting, negatively influencing the driving performance. To address these distractions, this research investigates the potential of displaying and delivering information in driver's peripheral vision via peripheral vision interface in a driving environment. Experimental findings suggest some benefits of implementation of such an information interface. However, the driver's perception of information presented by a peripheral vision interface is reduced due to cognitive load and optic flow generated while driving. The driver's perception varies depending on type of visual stimuli used to display information. The results are discussed and possible further developments are proposed.
