ABSTRACT:
The screen display scale is changed in an easy and intuitive manner, without intermediate steps or operations, and without taking up additional screen display area. At least one so-called scroll bar must be displayed on the screen and be functional at any time that the scale could be changed by the user. Additional function is loaded onto screen scroll bars to support the change of scale function as well as the scrolling function. The scroll bar is composed of a bar and a slider, and the slider position and size respectively indicate the location of working area relative to the virtual screen and the relative size of the working area as a function of the total size of the virtual screen area. Scrolling, or panning, is accomplished by moving the slider within the bar. In addition, the size of the slider can be changed in order to effect a change in the scale of the working area, thereby providing a zoom function for the scroll bar. The size of the slider can be changed in a number of ways, but all of them are intuitive and easily used by the user without requiring either intermediate steps or operations or taking up additional screen display area.
