Method for controlling position indicator of curved slider
View Patent ↗The presently disclosed technology provides curved slider GUIs with user interface sensitivity independent from a distance between a cursor and a radial center of the curved slider on a display. An area of operation is defined by an area between parallel bounds oriented equidistant from a radial center of a curved slider and extending from the outermost limits of the curved slider in both directions. Because of the geometry of the area of operation, a distance required to operate an entire range of the curved slider is independent from a distance between the cursor and the radial center of the curved slider. Since a distance that the cursor moves on the display often directly corresponds to movement of a physical input device, the presently disclosed technology results in a more intuitive operation of curved slider because the physical input motions more directly correlate to movements of the curved slider.
1. A method of manipulating an indicator on a curved slider, the method comprising:
defining a first bound corresponding to a first line that intersects a first limit of the curved slider and a second bound corresponding to a second line that intersects a second limit of the curved slider, wherein the first bound and the second bound are parallel and equidistant from a radial center of the curved slider;
associating a position of a cursor in a direction orthogonal to the first and second bounds to a position of the indicator on the curved slider where the position of the cursor is not directly on the curved slider; and
displaying on a display device the indicator at the position of the indicator on the curved slider.
2. The method of claim 1 , wherein the control panel is round.
3. The method of claim 1 , wherein a direction of curvature of the curved slider is adjustable for a right-handed or a left-handed user.

7. The method of claim 1 , wherein there is a linear relationship between movement of the cursor and movement of the indicator on the curved slider.
8. The method of claim 1 , wherein a distance of the cursor from one or both of the first and second bounds is equivalent to a distance of the indicator from one or both of the first and second bounds.
9. The method of claim 1 , wherein a distance of the cursor from one or both of the first and second bounds is proportional to a distance of the indicator along the curved slider.
