NAVIGATION DEVICE, NAVIGATION SYSTEM, CONTROL METHOD, NAVIGATION METHOD AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To present useful information to a user in a simple manner and provide additional information in augmented reality.

SOLUTION: A navigation device has an imaging unit capable of communicating with an information processor which stores and manages voice file information including vector information indicating directivity of voice files to be reproduced on a map. The navigation device comprises: transmission means for transmitting current position information acquired by a position information acquisition unit; imaging screen display means for starting the imaging unit to display an imaging screen on a display unit; acquisition means for acquiring the vector information included in the voice file which is reproducible with the current position information in the navigation device from the information processor to which the transmission means transmitted the current position information; first determination means for determining whether the vector information included in the voice file can be displayed on the display unit by using the directivity; and display means for displaying the vector information on the imaging screen when the first determination means determines that the vector information can be displayed on the display unit.
