Some human factors design issues and recommendations for automobile navigation information systems

This paper addresses some of the major human factors issues associated with automobile navigation information systems. Human factors objectives of navigation efficiency, ease, safety, and roadway use efficiency are specified. Major decision trade-offs for the display of navigation-related information and the operator control of navigation functions are addressed. When appropriate, design recommendations are made based on the current state of human factors knowledge. For every case, major underlying human factors concerns associated with various design alternatives are discussed.
