The present invention relates to a method for mitigating the inconvenience of being unable to touch a specific input object at an edge in a portable device having a large screen in the situation of having to use only one hand as a thumb cannot reach the edge of the screen. A specific object on the whole screen of a portable device can be touched with one hand as the function of snapping and panning, by which the snap action of the portable device is recognized via an acceleration sensor already installed in the portable device and the edge of the screen is moved to a position capable of being touched by a thumb, is realized. To achieve the purpose of the present invention, the method is characterized in reaction only to the snap action of a wrist, which is a motion with high acceleration for a short time, in handling an acceleration value to prevent confusion between general tilt or motion and the action of scrolling a screen. If an acceleration value in a Z-axis direction instead of eight desired direction of a user is too great or a snap action is conducted too rapidly and too many times, the motion is determined to be an undesired motion such as fall, and the action of scrolling a screen is not conducted. The method for scrolling a screen via a snap action using an acceleration sensor uses a technique for reducing the prevention of generation actions by the present action as the screen is automatically restored to a default screen when another screen is opened by touching a specific object after screen scroll in terms of operation or the screen is restored to an original screen if there is touch for a predetermined time. |
