Numeric input control through a non-linear slider

摘要

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.

主权项

1. A system for operating a nonlinear slider control comprising:
a computing device having a processor and having built-in or connection to a display device and one or more input devices, the computer device operating software to display a slider control on the display device, the slider control having:
a slider track;a slider on the slider track visually representing a current slider value;wherein the slider control is initialized with a current slider value and uses that current slider value to determine a range and a step interval size for the slider track; andwherein after a change to the current slider value, the range and step interval size for the slider track are redetermined based on the changed current slider value and such that determination and redetermination of range and step interval size place the slider position at a mid-point of the slider track.
