MOBILE ELECTRONIC DEVICE AND ITS DIRECTION DISPLAY METHOD

摘要

Provided is a mobile electronic device capable of effectively preventing erroneous recognition by a user that a displayed direction is correct when its reliability is lowered by a change of the ambient environment. A direction display method of the device is also provided. If a mobile electronic device (100) is mounted on a charger (200) having a speaker (201) while information on the direction calculated according to geomagnetism detected by a geomagnetic sensor (108) is displayed on a display unit (107), updating of the information on the direction repeated up to them is stopped and information on a predetermined direction is continuously displayed on the display unit (107). This enables a user to correctly recognize that the information on the direction displayed on the display unit (107) is incorrect, thereby preventing misleading of the user by the unreliable information on the display unit (107).
