ABSTRACT
Humans are inherently limited capacity creatures; that is, they are able to process only a small amount of the sensory information that is typically available at any given time. Although it is unclear what the exact nature of this limited capacity is, the inability of humans to simultaneously process multiple sources of sensory information places a number of important constraints on their attentional processing of stimuli both in the laboratory and in a number of real-life settings. The act of driving represents a highly complex skill requiring the sustained monitoring of integrated perceptual and cognitive inputs. However, limited published research has attempted to examine the potential beneficial or detrimental effects of such vibrotactile in-car systems on driving performance, and subsequently, on safety on the road. Several studies have explicitly assessed the utility of vibrotactile cues in simulated driving scenarios. The chapter also presents an overview of the key concepts discussed in this book.
