  • Patent number: 8046928
    Abstract: A method and device for calibrating a mobile terminal including a motion sensor reduces erroneous calibrations. The method of calibrating a mobile terminal by detecting an inclination of at least two directions preferably includes: activating a calibration mode for calibrating an error of the motion sensor. When a calibration mode is activated, a user interface screen for calibrating the motion sensor is output. The user interface screen outputs a coordinate system for displaying at least two facets of information; and inclination information of at least two directions received from the motion sensor is output as one image on the coordinate system.
