Method and apparatus for operating graphic menu bar and recording medium using the same

A non-transitory recording medium, suitable for recording a computer program, wherein the computer program comprises a plurality of program codes, which is loaded into a portable electronic device to execute a method for operating a graphic menu bar which comprises:

• providing a graphic menu bar, which comprises M graphic items arranged in sequence, wherein M is a positive integer;
• displaying N connected graphic items of the M graphic items along a coordinate axis direction in the graphic menu bar on the touch screen, wherein N is a positive integer smaller than M;
• and
• in response to detecting a touch signal in one of the N connected graphic items and the touch signal being moved toward the coordinate axis direction for a first displacement by the touch screen, moving the graphic menu bar displayed on the touch screen along a direction opposite to the coordinate axis direction for a second displacement, wherein the second displacement is equal to the product of the first displacement and (M−N)/N.

An apparatus for operating a graphic menu bar, comprising:

• a touch screen, for detecting a touch signal;
• a graphic menu bar generating module, for generating a graphic menu bar, wherein the graphic menu bar comprises M graphic items arranged in sequence, and wherein M is a positive integer;
• and
• a graphic menu bar displaying module, for displaying N connected graphic items of the M graphic items along a coordinate axis direction in the graphic menu bar on the touch screen, wherein N is a positive integer smaller than M;
• and
• wherein
• in response to detecting a touch signal in one of the N connected graphic items and the touch signal being moved toward the coordinate axis direction for a first displacement by the touch screen, the graphic menu bar displayed on the touch screen is moved toward a direction opposite to the coordinate axis direction for a second displacement, wherein the second displacement is equal to the product of the first displacement and (M−N)/N.
