The direction display device includes: a wireless communication section (48) to perform near field wireless communication; a barometric pressure measuring section (56); a converting section (41, 421) to convert barometric pressure into altitude; an orientation measuring section (58) to measure an orientation of a specified direction; an operation section (44); a display section (46); a registration controlling section (41) to obtain current positional information from an external positioning device on the basis of a registration instruction of the measured orientation to store the current positional information as registered positional information so as to be correlated to registered orientation information; a registration position extracting section (41) to extract the registered positional information including an altitude value whose difference from the converted altitude is within a predetermined range; and a display controlling section (41) to cause the display section to indicate a direction regarding the registered orientation correlated to the registered positional information. |
