ABSTRACT
The sophistication of in-vehicle technologies is rapidly increasing. Vehicles now come equipped with driver assistance systems, such as collision avoidance and electronic stability control, as well as complex in-vehicle information systems (IVIS), such as navigation, telecommunication, and entertainment systems. As IVIS complexity has increased, consumer tolerance for poor design has decreased (Stanton and Young 2003), and where consumers once considered usability a bonus, they are now likely to expect that the products they purchase are usable (Jordan, McClelland, and Thomas 1996). Therefore, designing usable IVIS can provide vehicle manufacturers with an important competitive advantage.
