7.2.4-6 Appropriate Use of Soft Sliders

A soft slider should be considered as an input device when the range of possible values and the ratio of a value to that range need to be displayed.

Additional Information:
A soft slider (also called a slider bar or a scroll bar) is an input format used to directly manipulate a variable over a set range of values. Soft sliders are typically maneuvered via pointing interfaces, such as a touch screen or mouse. They may require careful hand-eye coordination to ensure that the pointing device does not leave the linear path of the slider nor overshoot or undershoot the intended target. If the user's tasks do not permit careful hand-eye coordination, then other interfaces, such as arrow keys, should be used. The slider sometimes is combined with arrow buttons.
