Patent ID: 8825086

Claim:
A direction display device comprising: a wireless communication section to perform near field wireless communication with an external device; a barometric pressure measuring section to measure barometric pressure; a converting section to convert the barometric pressure measured by the barometric pressure measuring section into an altitude value; an orientation measuring section to measure an orientation of a specified direction; an operation section to receive an input operation; a display section to display information; a registration controlling section to obtain current positional information by the wireless communication section from an external positioning device to store the current positional information as registered positional information while correlating the current positional information to registered orientation information which is of the measured orientation, when the input operation of registration instruction of measured orientation has been detected; a registration position extracting section to extract the registered positional information according to which a difference between the altitude value converted by the converting section and an altitude value obtained from the registered positional information stored is within a predetermined range; and a display controlling section to cause, when one or more pieces of the registered positional information has been extracted by the registration position extracting section, the display section to indicate a direction regarding the registered orientation information stored so as to be correlated to the registered positional information, according to the current position measured by the positioning device and a position regarding the registered positional information extracted.
