Introduction
In-vehicle systems can do much to improve both the driver experience and safety while driving. However, the plethora of new capabilities and services becoming available through in-vehicle systems can also have the opposite effect by adding to distractions and, more subtly, by ...
Cognitive load
In lay terms, cognitive load can be defined as the amount of work a subject’s brain is doing at any given time. Cognitive load affects, among other things, the subject’s ability to learn, his ability to respond to and interpret stimuli, and his ability to perform even commonplace tasks. As Ton de Jong writes in “Cognitive load theory, education research and ...
Spatial auditory displays
Today, in-vehicle audio systems are designed so that users perceive all sounds emitted by most non-music applications as coming from a single location in the vehicle. In contrast, spatial auditory displays cause users to perceive sound as coming from different locations in a three-dimensional space. These perceived locations may be different positions inside the vehicle, or even locations slightly ...
Improvements to driver performance
Spatial auditory displays can improve driver performance because it can improve the human-machine interface the driver uses to communicate with his vehicle. These improvements, essentially error reduction, shortening of response times, and better comprehension, enable better task performance and, hence, a) lessen the effort required to perform a driving-related or a ...
Conclusion
As more and more applications are introduced into vehicles, the need to minimize their impact on the driver’s ability to perform his primary task—drive safely—will only increase. Spatial auditory displays will prove invaluable both for facilitating human-machine interaction in the vehicle and as an enabling technology for new ...
