Visual Sampling of In-Vehicle Text Messages

io, navigation, information systems and other sources is to develop methods to present text information that are efficient, simple, and place the fewest demands on the driver's attention. While such data should enhance drivers' experience in terms of overall enjoyment, travel time and efficiency, improperly displayed and controlled text messages may distract drivers and lead them to miss critical driving events. The design of text message format and control therefore becomes an important influence on the drivers' overall visual sampling behavior. Current guidelines provide direction for the development of advanced in-vehicle displays, which include principles that apply to the presentation of text information such as appropriate fonts and message complexity (1, 2). However, these guidelines focus primarily on succinct vehicle state and navigation information, with the intent of minimizing display induced distraction.
