A study on a split-view navigation system

Abstract

CNS (Car Navigation System) provides traffic information with an intention to offer safe and comfortable driving experience. However, because too much information is presented into a single screen it often becomes information-crowded. This paper analyzed four commercial CNS products to collect information elements and conducted user studies such as focused groups, surveys and interviews to determine what information is needed for each position of the seat; the driver and the passenger seat. The result showed that there is clear difference in information priority between driver and the person on passenger seat. Based on such finding, this paper proposes using split-view based CNS. Split-view CNS contributes to enhance user satisfaction of driving experience by providing different information to needed for a driver and a passenger.
