NAVIGATION DEVICE AND METHOD FOR MANAGING INFORMATION SHARED BY A PLURALITY OF NAVIGATION DEVICES

摘要

Within a group consisting of a plurality of vehicles, users of the vehicles have difficulty in communicating with one another. A navigation device (12) includes a monitor (23) having a display screen on which map information stored in a map information storage unit (24) is displayed. The navigation device (12) includes: a communication unit (21) which can communicate with other navigation device (12) via a server device (11) or directly; a touch panel (28) for inputting handwritten information by operation on the display screen and acquiring a position coordinate of the handwritten information on the display screen; a handwritten information storage unit (25) for storing the position coordinate of the handwritten information and shape data on the handwritten information; and a common information managing unit (27) for managing handwritten information whose position coordinate is converted into longitude-latitude information in the map information and associated with map information as common information shared by the local and other navigation device (12).
