enough for rapid comprehension. The organization of contents seems oriented to a user browsing at work or home, not the driver. The colors and fonts are not legible and readable for viewing in the typical ambient light or viewing-distance conditions of vehicles. The interactions are oriented to detailed desktop targets, not the simplified dashboard layouts. Internet-based displays still seem in need of design for the specific target market and conditions of the driver en route.
The approach to the UI development process, the specific UI design results, and the lessons learned seem to have value for designers of current and nextgeneration traveler information systems and consumer devices in general. Note: This paper is adapted from ( Marcus 1999).
