  • Publication number: 20110037621
    Abstract: A data display device includes: a position obtaining unit obtaining current position data of a mobile object; a direction obtaining unit obtaining traveling direction data of the mobile object; a display control unit causing a display unit to display a current position and a traveling direction of the mobile object based on the current position data and the traveling direction data of the mobile object; and a determining unit determining that the mobile object has entered or exited a parking lot based on the current position data of the mobile object. The display control unit causes the display unit to display the mobile object so the current position of the mobile object is not changed and only the traveling direction of the mobile object is changed, from a determination that the mobile object has entered the parking lot until a determination that the mobile object has exited the parking lot.
