Abstract

An exemplary content scrolling system includes a display unit for displaying content, a scroll bar for scrolling the displayed content, and a processing unit for scrolling the displayed content based on a scroll input of the scroll bar. The processing unit includes a scroll amount calculating module and a content scrolling module. The scroll amount calculating module is for calculating for calculating a scroll amount mapping to the scroll input according to a particular formula. The content scrolling module is for scrolling the displayed content according to the scroll amount. Related exemplary content scrolling methods are also provided.
