Method and apparatus for navigating content on screen using pointing device

摘要

A method and an apparatus for navigating content larger than a display screen of a terminal using a pointing device are provided. The method includes acquiring, when a pointing position is changed on a screen partially displaying a content that is larger than the screen, a current pointing position by tracking the change of the pointing position, comparing an X axis displacement and a Y axis displacement from an initial pointing position as a starting position to the current pointing position with a predefined X axis threshold value and Y axis threshold value, respectively, determining a movement direction as one of an X axis, a Y axis, and an XY (diagonal) axis directions based on the comparison result, and scrolling the content in the movement direction to display an off-screen part of the content.

1. A content navigation method using a pointing device, the method comprising:
acquiring, when a pointing position is changed on a screen partially displaying a content that is larger than the screen, a current pointing position by tracking the change of the pointing position; comparing an X axis displacement and a Y axis displacement from an initial pointing position as a starting position to the current pointing position with a predefined X axis threshold value and Y axis threshold value, respectively; determining a movement direction as one of an X axis, a Y axis, and an XY (diagonal) axis directions based on the comparison result; scrolling the content in the movement direction to display an off-screen part of the content; determining whether the current pointing position stays without movement over a predefined time period; storing a setting value indicating that the starting point is to be reset when the current pointing position is determined to stay without movement over the predefined time period; determining to reset the starting point when the stored setting value indicates that the starting point is to be reset; and resetting the starting point to be the current pointing position when the determination is made to reset the starting point.
