Simplifying the Possibilities: Properties and Prioritization of Driver Interface Design

As technology advances, it is possible to present the driver with more information and communication options than ever before. Intelligent transportation system products will make new and additional demands on the driver's attentional and cognitive abilities. Today, in-vehicle cellular phones and faxes are common, and soon wireless communication with the Internet and various other forms of specialized information will be available to drivers as well. The challenge is to develop a human-machine interface (HMI) that is beneficial yet simple and easy to use as more demands are made on the driver. This paper provides guidance in utilizing human factors properties to ensure simplicity and prioritization of tasks in HMI development
