US Patent 9442646 Numeric input control through a non-linear slider

The disclosed non-linear slider control enables a single control to rapidly change orders of magnitude in the scale of control by varying the bounds and quantization interval based on the value before the user begins a slide operation. The bigger the value is at the start, the larger the bounds and the interval. At the end of the slide operation, the bounds and step interval value are recomputed such that the end of the slider operation is centered in the new bounds.
